50 Validators Projects on Near Network

In this article, you'll learn Near Validators and 50 Validators Projects on Near Network

The mission of NEAR is to empower people to manage their assets, data, and the power of governance. Validators support this mission by ensuring a single entity cannot control or manipulate the way a network governs itself or manages data. 

In the NEAR Proof-of-Stake network, a decentralized pool of validators process transactions to keep the network secure. In return, these validators receive a reward for doing so. This system also allows delegators – entities that would like to provide security but may not have the hardware to do – to delegate their tokens to validators.

The NEAR network is now secured by 100 block producing validators, and thousands of delegators. However, our mission is to bring more validators and delegators online to further decentralize the network. 

Please join the validator community to secure the NEAR network, support decentralization, and earn rewards.

Benefits

  • Support NEAR’s mission to empower people to manage their assets, data, & governance
  • Secure the NEAR network 
  • Decentralize data and governance
  • Earn staking rewards
  • Provide staking service for delegators and earn commission

Block Producing Validators

Validators are responsible for producing blocks and the security of the NEAR network. Since Validators validate all shards, they can run the validator node on an 8-Core CPU, with 16GB of RAM, and 1 TB SSD of storage. The current plan is to have 100 Validators. The cost of running a block-producing validator node is estimated to be $330 per month for hosting. 

The current active Validators are available on the Explorer. The minimum seat price to become a block-producing validator is based on the 100th proposal. (If more than 100 proposals are submitted, the threshold will simply be the stake of the 100th proposal, provided that it’s larger than the minimum threshold of 67,000 $NEAR.) The current seat price to become a block-producing validator is updated live on the Explorer. Any validator nodes with stakes higher than the seat price can join the active set of Validators.

Rewards

Protocol Rewards

45m $NEAR are distributed per year to the validators and delegators. Current reward rate is ~12% given the amount staked. For more details about the Validator’s economics.

Commission Fee

Validators have the ability to charge a commission on the delegation staked to their node. Each validator may decide their own commission fee structure and how reward distribution works. The typical commission fee is around 5%.

Top 20 Crypto Wallet for iOS you Need to Know

As an investor or a crypto enthusiast, you may have now been familiarized with Bitcoin, Crypto and its transactions. With the advent of technology, you can even transact using your smartphone. But, as you know, you need Crypto wallets to store and transact your Crypto.

The idea of accessing Crypto from your smartphone seems legit; after all, who wants to invest in digital ledgers and high-end software when you have mobile applications.

In this article, you'll learn What is Crypto Wallet for iOS, Top 20 Crypto Wallet for iOS you Need to Know?

What Are iOS Crypto Wallets?

As the name implies, they are iOS-based mobile applications designed to help store cryptocurrency. The only difference between these applications and the generic mobile wallets is that they are only compatible with iOS devices.

Simply put, with an iOS crypto wallet, you can store crypto on your iPhone or iPad, which has the added benefit of allowing you access your funds instantaneously. Apart from instant access to your crypto stash, there are other benefits of using iOS wallets. Likewise, you should note that there are also inherent risks associated with this model of wallets.

What Are the Benefits of Using iOS Crypto Wallets?

You can simply click the app to verify your identity and access different tools made available for the tracking and transacting cryptocurrency. Needless to say, this functionality is the major reason why mobile wallets are becoming quite popular.

It helps crypto practitioners evade threats associated with entrusting the security of their private keys to web wallets. You only need to download an app from a trusted source instead of worrying about verifying crypto sites whenever want to utilize wallets.

Using an iOS mobile wallet entails crypto holders to download an application on the Appstore. Since Apple often scrutinizes the apps listed on its mobile marketplace, it is rare to fall victim to scammers that use fake apps to lure people into disclosing sensitive information regarding their crypto holdings.

What Are the Downsides of Adopting An iOS Wallet?

Users might permanently lose access to their crypto holdings when they misplace their devices. Considering that the wallet is embedded on mobile phones, a damaged or lost phone could cause users to panic, especially if they do not have a way of recovering lost wallets.

In cases where users lose their devices to experienced hackers, there is no guarantee that they will still have access to the content of the wallet once reactivated on another device.

How Can Users Circumvent These Risks?

To mitigate the risk mentioned above, iOS wallet users must ensure that their devices do not fall into the hands of malicious entities or anyone they do not trust.

Also, it is imperative to only adopt wallets availing recovery processes for lost wallets. When you opt for a wallet that provides a recovery phrase, you can rest assured that it is possible to recover your funds if you lose or damage your iOS device.

Likewise, we suggest that you take extra care if your iOS has already been jailbroken. Note that jailbreaking an Apple device gives you access to restricted third-party apps and strips you of Apple’s regulatory framework governing the Appstore. Hence, you ought to verify the authenticity of the wallet app you are about to download and ensure that it is not linked to a fraudulent scheme.

You can also ensure the safety of your holdings while utilizing an iOS wallet app by adopting it as a secondary crypto storage system. It is advisable to opt for a hardware wallet as the primary storage facility where you hold a large fraction of your crypto holdings. And if you must use a mobile wallet to supplement this, you should only store an inconsequential sum of crypto on your iOS wallet to mitigate the risk of losing all your funds to a single attack.

How to Chose iOS Wallet Apps?

  • The Jurisdictions Where the Wallet Service Is Available: The first factor that you should consider before kickstarting your research is the jurisdiction that the iOS wallet app you are considering supports.
  • The Number of Cryptocurrencies It Supports: You should check that the platform supports all of your favorite coins.
  • Security is another important detail that you should consider: authentication (2FA) - process that would eliminate the risks of losing your digital asset to entities that might have stolen your identity.
  • The Reputation of the iOS Crypto Wallet Provider
  • The Customer Support Culture of the iOS Crypto Wallet
  • Beginner-Friendliness and User Experience
  • Additional Features Available on The iOS Wallet

Jaxx LibertyThis is the best Bitcoin wallet for iPhone users who are new to the world of cryptocurrencies. While it is meant for the beginners, it remains feature-rich for experienced users. The wallet can hold more than 85 different digital assets, and thanks to its gamified user-interface, new users find it an easy and enjoyable experience.

It comes with a host of features that sets it apart from other iOS Bitcoin wallets. For starters, you get to store and transact multiple currencies and not just Bitcoin. If you deal with multiple cryptocurrencies, Jaxx Liberty enables you to keep them all in one place, adding to the convenience factor. We like that the Jaxx Liberty development team is highly involved with the app users. They are open to suggestions and are happy to accept requests.

What makes it one of the best Bitcoin wallets for iOS is its unified dashboard, where you can see all your wallets, and it also gives you a complete picture of all of your holdings. There is a portfolio module that enables you to stay abreast of the latest value of your holdings in real-time.

You will also find a blockchain news viewer integrated within the iOS application that keeps you updated on the breaking news and latest developments in the crypto world. There is built-in support for ShapeShift, using which you can exchange Bitcoin with any other cryptocurrency, and vice-versa, without needing to leave your wallet.

There is an improved security model for Jaxx Liberty, where all your sensitive information will be protected by a strong password that uses AES-256 encryption. Nevertheless, the iOS app may lag a little on some occasions. All in all, it is one of our favorites, and you should definitely try it.

BRDThe Bread wallet is a mobile wallet for Bitcoin and Bitcoin Cash. The wallet was established in 2015. It is available on both Android and iOS. Users are in control of their private key. The wallet only supports Bitcoin and Bitcoin Cash which makes it somewhat limited when compared to competitors. The wallet connects directly to the Bitcoin network. This ensures that Bread does not see any sensitive information and users are at no risk of the servers going down or being hacked.

The wallet is hierarchical deterministic. The code is open-source. It does not have multi-signature optionality. There is also no option for users to enable two-factor authentication.

The wallet has a very straightforward user interface which makes it easy and intuitive for beginners to use. However, it also has features which offer security to more advanced users. Bread has recently expanded their services from being a wallet to also being a decentralized platform for cryptocurrency users. They raised money for the expansion via an ICO. The native token of the ICO, BRD, provides users of the Bread decentralized platform with certain rewards such as discounts on services. Overall, Bread has good reviews as a wallet but is limited in its functionality and the building of the decentralized platform may take resources away from the wallet. The support help has been noted to be good.

CoinomiCoinomi is a popular and probably the best Bitcoin wallet for iPhone because it can store over a whopping 500 coins. This wallet for iOS has always kept its focus on privacy. The app is easy and quick to install and allows you to exchange your crypto coins from within the wallet. Despite the questionable allegations of a security bug in the Desktop app back in 2019, Coinomi has maintained a good reputation among investors and crypto enthusiasts

This is a feature-rich Bitcoin wallet meant for advanced users. But beginners and intermediates can also use it to learn the advanced levels. As said, Coinomi has an extensive crypto coin coverage, providing true ownership and native support for over 125 blockchain assets. The wallet also supports over 382 tokens. Since it has ERC20 token standard support, you can add your preferred amount of customized tokens as you like. Coinomi is SegWit-enabled, meaning you can make transactions that are much ‘lighter.’ You can also set custom or dynamic fees where you can set your own fee to be used or decide a fee that gives you the best value for money at the time.

Since crypto coins are always at the risk of hacks, Coinomi offers private key storage that is kept entirely restricted to your iOS device. Therefore, unless you purposely provide others access to your iOS device, no one can extract the private keys. Apart from security, Coinomi also takes care of the user’s privacy. In short, Coinomi excels at privacy as it doesn’t collect any personal information from the user. The best thing about it is that the app even goes as far as to hide your IP address.

What we like the most about this iOS Bitcoin wallet is its user-friendliness. You will find clearly visible options, easy navigation, and all these at just a few taps and clicks at most.

Furthermore, it is not just wallets, but Coinomi also offers a wallet exchange feature as well. This means you can exchange one cryptocurrency for another without having to leave your device.

All these features make Coinomi one of the best Bitcoin wallets for iPad. Nevertheless, while the features are easy to understand and utilize, it is common for beginners to get overwhelmed with so many features.

Conclusion

Remember, a bitcoin exchange IS NOT a safe place to store your bitcoins. A bitcoin wallet will offer much better security features than your typical bitcoin exchange. Even when using a wallet, we recommend adhering to the following points: 

  • ALWAYS set a pin to protect your wallet
  • Write down your 12 – 24 seed phrase and store it somewhere safe
  • DO NOT store large amounts of bitcoins on your mobile wallet, only on hardware wallets.

Understanding the Crypto Fundraising Models

What is an Initial Coin Offering (ICO)?

In the crypto world, an Initial Coin Offering (ICO) is equivalent to an Initial Public Offering (IPO) (IPO). The term "Initial Coin Offering" refers to a fundraising model that aids in the capitalization of the cryptocurrency industry. An ICO can be launched by a company or a new coin to raise funds. Interested investors can participate in the initial coin offering in exchange for a new crypto token issued by the company.

The process begins with a new or established company looking to raise capital for growth. It is a fundraising event for a new cryptocurrency asset, company, or venture.

What is an Initial DEX Offering (IDO)?

A crypto token offering that runs on a Decentralized Exchange is an Initial Decentralized Exchange (DEX) Offering. Liquidity pools (LP) play an essential role by providing liquidity after the sale. The initial DEX offering during a token generation event allows users to lock their funds in exchange for new tokens, providing a cost-effective and more accessible way for projects to distribute tokens.

Initial DEX offerings are similar to ICOs and IEOs in that they seek to raise funds and bootstrap a project. Unlike ICOs and IEOs, where tokens are sold before listing, IDOs are immediately listed on a decentralized exchange.

What is an Initial Exchange Offering (IEO)?

An Initial Exchange Offering (IEO) is a type of crowdfunding managed by an exchange platform. Unlike an ICO, where the project team is in charge of fundraising, an Initial Exchange Offering is made through an exchange platform. Users can directly purchase tokens in IEO using funds from their exchange wallet.

IEO is a simple fundraising model in which users only need an exchange platform account with some funds to participate. Where the exchange is staking its reputation for a project on its platform, IEOs provide a high level of trust and transparency.

What is an Initial Farming Offering (IFO)?

Initial Farming Offering (IFO) is a fundraising model that assists newly launched Defi projects in raising capital through participation in pre-sales events. The Initial Funding Offering (IFO) is the successor to the Initial Coin Offering (ICO), which depicts a crowdsourcing method used by crypto projects to raise capital in the early stages.

Investors can raise the capital needed for the available projects by participating in DEX's re-sales event. IFOs, which serve to raise funds for crypto projects, are both similar and distinct from IEOs and ICOs.

What is an Initial Liquidity Offering (ILO)?

An Initial Liquidity Offering (ILO) is a fundraising model in which a new token is offered to buyers who agree to contribute to a liquidity pool. Because the token is attracting new buyers, the Automated Market Maker (AMM) can function. It allows multiple projects and startups to raise funds by selling tokens on Defi-based DEX platforms instead of conducting an ICO.

ILOs are simple to carry out on Defi-based DEX platforms because they have many investors who may be interested in purchasing the crypto tokens immediately for a higher price. These DEXs use the AMM mechanism, which manages liquidity pools through highly skilled liquidity providers.

What is an Initial NFT Offering (INO)?

NFTs have played various roles in reaching out to the target audience and generating interest in new tokens or any business. NFT can be used as a marketing tool to attract customers by providing them with some benefit that benefits the NFT holder. At such times, the initial offering of NFT is the opportunity for the customer to acquire the NFT and use the utility for a specific project.

This INO (Initial NFT Offering) can be used as a marketing strategy or fundraising model. The main thing is to look at the number of people interested in the use case and the project's popularity. Sometimes a free NFT offering will include a few tasks to complete that will help spread the project to more people.

Please contact Suffescom Solutions, an IDO Development Company, if you want to develop any fundraising models.

Obtener La Dirección De La Billetera Usando WalletConnect En Android

El crecimiento de la tecnología Blockchain ha sido tan rápido que incluso aquellos que no han oído hablar de las criptomonedas o conocen su funcionamiento buscan invertir y explorar este campo. Según un estudio realizado por The Independent, el 11% de los británicos encuestados dijeron que estarían interesados ​​en las criptomonedas o la tecnología blockchain si se familiarizaran más con ella. A medida que el rumor en torno a las criptomonedas continúa extendiéndose por todo el mundo y más empresas emergentes desarrollan nuevas formas de utilizar la tecnología blockchain todos los días, no es de extrañar que más personas estén interesadas en invertir en este espacio.

En este breve artículo, aprenderemos cómo conectar una billetera criptográfica a nuestra aplicación de Android usando Jetpack Compose y WalletConnect.

¿Qué son las CryptoWallets?

Cuando hablamos de criptomonedas, hay algo muy importante llamado CryptoWallet. CrypoWallets están diseñados para almacenar activos digitales y validar transacciones. Una billetera guarda información secreta utilizando una clave privada utilizada para firmar transacciones. Las billeteras criptográficas son una forma segura de almacenar y administrar sus monedas y tokens, pero existen algunos tipos diferentes de billeteras en el mercado:

  1. Billeteras populares
    — Billeteras de escritorio
    — Billeteras web
    — Billeteras móviles
  2. Carteras frías
    - Cartera de hardware
    - Cartera de papel

¿Qué es Wallet Connect?

WalletConnect es un protocolo abierto para comunicarse de forma segura entre Wallets y Dapps (Web3 Apps). El protocolo establece una conexión remota entre dos aplicaciones y/o dispositivos utilizando un servidor Bridge para transmitir cargas útiles. Estas cargas útiles se cifran simétricamente a través de una clave compartida entre los dos pares.

La conexión la inicia un compañero que muestra un código QR o un enlace profundo con un URI estándar de WalletConnect y se establece cuando la contraparte aprueba esta solicitud de conexión. También incluye un servidor Push opcional para permitir que las aplicaciones nativas notifiquen al usuario las cargas útiles entrantes para las conexiones establecidas.

¿Qué es Jetpack Compose?

Jetpack Compose es una herramienta moderna de Android para crear interfaces de usuario nativas desarrollada por Google Developers. Jetpack Compose se compara con SwiftUI utilizado en el desarrollo de aplicaciones iOS. Esta analogía se basa en un diseño más sencillo, menos código y más lógica comercial.

Jetpack Compose simplifica el desarrollo de la interfaz de usuario en las aplicaciones de Android y permite un desarrollo de aplicaciones más rápido. El lema de Jetpack Compose es menos código, herramientas potentes, API Kotlin intuitivas y desarrollo rápido de aplicaciones.

Conectar Wallet a la aplicación de Android

En esta sección, vamos a conectar Wallet a nuestra aplicación de Android y obtener la dirección de usuario mediante Wallet Connect SDK .

Dependencias de configuración

Dentro build.gradledel archivo (Módulo) debe agregar las siguientes implementaciones.

    // Wallet Connect
    implementation 'com.github.WalletConnect:kotlin-walletconnect-lib:0.9.6'
    implementation "com.github.komputing:khex:1.0.0-RC6"
    implementation "org.java-websocket:Java-WebSocket:1.4.0"
    implementation 'com.squareup.moshi:moshi:1.8.0'
    implementation "com.squareup.okhttp3:okhttp:4.9.1"

    // Hilt
    implementation "com.google.dagger:hilt-android:2.38.1"
    kapt "com.google.dagger:hilt-compiler:2.38.1"
    implementation "androidx.hilt:hilt-navigation-compose:1.0.0-beta01"

Después de esto, agregue kaptcomplementos de empuñadura en la parte superior del build.gradlearchivo.

plugins {
    // Other plugins...
    
    id 'dagger.hilt.android.plugin'
    id 'kotlin-kapt'
}

Agregar classpath al build.gradlearchivo (Proyecto)


    dependencies {
        // Hilt
        classpath 'com.google.dagger:hilt-android-gradle-plugin:2.40.5'
    }

Y no olvide agregar la siguiente línea a su build.gradlearchivo. Si está utilizando Android Studio Canary, debe agregar esta línea a su settings.gradlearchivo. Luego haga clic en el botón sincronizar ahora.

maven { url 'https://jitpack.io' }

Configuración del módulo de empuñadura

Para conectar WalletConnect, necesitamos un archivo y un par de objetos de red. Para crear estos objetos vamos a utilizar Inyección de Dependencia. El siguiente código es nuestro módulo Wallet Connect.

@InstallIn(SingletonComponent::class)
@Module
object WalletConnectModule {

    @Provides
    @Singleton
    fun provideMoshi(): Moshi = Moshi.Builder().build()

    @Provides
    @Singleton
    fun provideOkhttpClient(): OkHttpClient = OkHttpClient.Builder().build()

    @Provides
    @Singleton
    fun provideSessionStorage(
        @ApplicationContext context: Context,
        moshi: Moshi,
    ): WCSessionStore = FileWCSessionStore(File(context.cacheDir, "session_store.json").apply { createNewFile() },
        moshi)
}

Configurar BirdgeServer

Para conectar nuestra aplicación a Wallet, necesitamos un Servidor Socket. Aquí hay un código sobre cómo generar este servidor.

class BridgeServer(moshi: Moshi) : WebSocketServer(InetSocketAddress(PORT)) {

    private val adapter = moshi.adapter<Map<String, String>>(
            Types.newParameterizedType(
                    Map::class.java,
                    String::class.java,
                    String::class.java
            )
    )

    private val pubs: MutableMap<String, MutableList<WeakReference<WebSocket>>> = ConcurrentHashMap()
    private val pubsLock = Any()
    private val pubsCache: MutableMap<String, String?> = ConcurrentHashMap()

    override fun onOpen(conn: WebSocket?, handshake: ClientHandshake?) {
        Log.d("#####", "onOpen: ${conn?.remoteSocketAddress?.address?.hostAddress}")
    }

    override fun onClose(conn: WebSocket?, code: Int, reason: String?, remote: Boolean) {
        Log.d("#####", "onClose: ${conn?.remoteSocketAddress?.address?.hostAddress}")
        conn?.let { cleanUpSocket(it) }
    }

    override fun onMessage(conn: WebSocket?, message: String?) {
        Log.d("#####", "Message: $message")
        try {
            conn ?: error("Unknown socket")
            message?.also {
                val msg = adapter.fromJson(it) ?: error("Invalid message")
                val type: String = msg["type"] ?: error("Type not found")
                val topic: String = msg["topic"] ?: error("Topic not found")
                when (type) {
                    "pub" -> {
                        var sendMessage = false
                        pubs[topic]?.forEach { r ->
                            r.get()?.apply {
                                send(message)
                                sendMessage = true
                            }
                        }
                        if (!sendMessage) {
                            Log.d("#####", "Cache message: $message")
                            pubsCache[topic] = message
                        }
                    }
                    "sub" -> {
                        pubs.getOrPut(topic, { mutableListOf() }).add(WeakReference(conn))
                        pubsCache[topic]?.let { cached ->
                            Log.d("#####", "Send cached: $cached")
                            conn.send(cached)
                        }
                    }
                    else -> error("Unknown type")
                }
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

    override fun onStart() {
        Log.d("#####", "Server started")
        connectionLostTimeout = 0
    }

    override fun onError(conn: WebSocket?, ex: Exception?) {
        Log.d("#####", "onError")
        ex?.printStackTrace()
        conn?.let { cleanUpSocket(it) }
    }

    private fun cleanUpSocket(conn: WebSocket) {
        synchronized(pubsLock) {
            pubs.forEach {
                it.value.removeAll { r -> r.get().let { v -> v == null || v == conn } }
            }
        }
    }

    companion object {
        val PORT = 5000 + Random().nextInt(60000)
    }
}

Crear instancia de Wallet Connect

        config =
            Session.Config(UUID.randomUUID().toString(), "https://bridge.walletconnect.org", key)
        session = WCSession(
            config ?: return,
            MoshiPayloadAdapter(moshi),

        )
        session?.offer()
    }


    fun connectWallet(context: Context) {
        resetSession()
        activeCallback = object : Session.Callback {
            override fun onMethodCall(call: Session.MethodCall) = Unit

            override fun onStatus(status: Session.Status) {
                status.handleStatus()
            }
        }
        session?.addCallback(activeCallback ?: return)
        context.startActivity(Intent(Intent.ACTION_VIEW).apply {

    }

    fun Session.Status.handleStatus() {

        // val walletType = session?.peerMeta()?.name ?: ""
        userWallet.value = address
    }

    private fun sessionClosed() {

    }
}

 Obtener La Dirección De La Billetera Usando WalletConnect En Android

AndroidでWalletConnectを使用してウォレットアドレスを取得する

ブロックチェーンテクノロジーの成長は非常に急速であるため、暗号通貨について聞いたことがない、またはその仕事について知らない人でも、この分野に投資して探索しようとしています。The Independentが実施した調査によると、調査対象の英国人の11%が、暗号通貨やブロックチェーンテクノロジーに慣れれば、それに興味があると答えています。暗号通貨に関する話題が世界中に広がり続け、より多くのスタートアップがブロックチェーンテクノロジーを使用する新しい方法を毎日開発しているので、より多くの人々がこの分野への投資に興味を持っているのも不思議ではありません。

この短い記事では、JetpackComposeとWalletConnectを使用して暗号ウォレットをAndroidアプリに接続する方法を学習します。

CryptoWalletsとは何ですか?

私たちが暗号通貨について話すとき、CryptoWalletと呼ばれる最も重要なものがあります。CrypoWalletsは、デジタル資産を保存し、トランザクションを検証するように設計されています。ウォレットは、トランザクションの署名に使用される秘密鍵を使用して秘密情報を保持します。暗号通貨ウォレットは、コインやトークンを安全に保管および管理する方法ですが、市場にはいくつかの異なるタイプのウォレットがあります。

  1. ホットウォレット
    —デスクトップウォレット
    — Webウォレット
    —モバイルウォレット
  2. コールドウォレット
    —ハードウェアウォレット
    —ペーパーウォレット

WalletConnectとは何ですか?

WalletConnectは、WalletとDapps(Web3 Apps)の間で安全に通信するためのオープンプロトコルです。プロトコルは、ペイロードを中継するためにBridgeサーバーを使用して、2つのアプリやデバイス間のリモート接続を確立します。これらのペイロードは、2つのピア間の共有キーを介して対称的に暗号化されます。

接続は、QRコードまたは標準のWalletConnect URIを使用したディープリンクを表示する1つのピアによって開始され、カウンターパーティがこの接続要求を承認したときに確立されます。また、オプションのプッシュサーバーが含まれており、ネイティブアプリケーションが確立された接続の着信ペイロードをユーザーに通知できるようにします。

Jetpack Composeとは何ですか?

Jetpack Composeは、GoogleDevelopersによって開発されたネイティブUIを作成するためのAndroidモダンツールです。Jetpack Composeは、iOSアプリ開発で使用されるSwiftUIに例えられます。この例えは、より簡単な設計、より少ないコード、およびより多くのビジネスロジックに基づいています。

Jetpack Composeは、AndroidアプリでのUI開発を簡素化し、アプリ開発を高速化します。Jetpack Composeのモットーは、コードの削減、強力なツール、直感的なKotlin API、および迅速なアプリケーション開発です。

ウォレットをAndroidアプリに接続する

このセクションでは、WalletをAndroidアプリに接続し、WalletConnectSDKを使用してユーザーアドレスを取得します

依存関係の設定

(モジュール)ファイル内build.gradleに、以下の実装を追加する必要があります。

    // Wallet Connect
    implementation 'com.github.WalletConnect:kotlin-walletconnect-lib:0.9.6'
    implementation "com.github.komputing:khex:1.0.0-RC6"
    implementation "org.java-websocket:Java-WebSocket:1.4.0"
    implementation 'com.squareup.moshi:moshi:1.8.0'
    implementation "com.squareup.okhttp3:okhttp:4.9.1"

    // Hilt
    implementation "com.google.dagger:hilt-android:2.38.1"
    kapt "com.google.dagger:hilt-compiler:2.38.1"
    implementation "androidx.hilt:hilt-navigation-compose:1.0.0-beta01"

この後、プラグインをファイルの先頭に追加kaptしてhiltしbuild.gradleます。

plugins {
    // Other plugins...
    
    id 'dagger.hilt.android.plugin'
    id 'kotlin-kapt'
}

build.gradle(プロジェクト)ファイルにクラスパスを追加する


    dependencies {
        // Hilt
        classpath 'com.google.dagger:hilt-android-gradle-plugin:2.40.5'
    }

build.gradleそして、ファイルに以下の行を追加することを忘れないでください。Android Studio Canaryを使用している場合は、この行をsettings.gradleファイルに追加する必要があります。次に、[今すぐ同期]ボタンをクリックします。

maven { url 'https://jitpack.io' }

ヒルトモジュールのセットアップ

接続WalletConnectするには、ファイルといくつかのネットワークオブジェクトが必要です。これらのオブジェクトを作成するには、依存性注入を使用します。以下のコードは、WalletConnectモジュールです。

@InstallIn(SingletonComponent::class)
@Module
object WalletConnectModule {

    @Provides
    @Singleton
    fun provideMoshi(): Moshi = Moshi.Builder().build()

    @Provides
    @Singleton
    fun provideOkhttpClient(): OkHttpClient = OkHttpClient.Builder().build()

    @Provides
    @Singleton
    fun provideSessionStorage(
        @ApplicationContext context: Context,
        moshi: Moshi,
    ): WCSessionStore = FileWCSessionStore(File(context.cacheDir, "session_store.json").apply { createNewFile() },
        moshi)
}

BirdgeServerをセットアップする

アプリをウォレットに接続するには、ソケットサーバーが必要です。このサーバーを生成する方法のコードは次のとおりです。

class BridgeServer(moshi: Moshi) : WebSocketServer(InetSocketAddress(PORT)) {

    private val adapter = moshi.adapter<Map<String, String>>(
            Types.newParameterizedType(
                    Map::class.java,
                    String::class.java,
                    String::class.java
            )
    )

    private val pubs: MutableMap<String, MutableList<WeakReference<WebSocket>>> = ConcurrentHashMap()
    private val pubsLock = Any()
    private val pubsCache: MutableMap<String, String?> = ConcurrentHashMap()

    override fun onOpen(conn: WebSocket?, handshake: ClientHandshake?) {
        Log.d("#####", "onOpen: ${conn?.remoteSocketAddress?.address?.hostAddress}")
    }

    override fun onClose(conn: WebSocket?, code: Int, reason: String?, remote: Boolean) {
        Log.d("#####", "onClose: ${conn?.remoteSocketAddress?.address?.hostAddress}")
        conn?.let { cleanUpSocket(it) }
    }

    override fun onMessage(conn: WebSocket?, message: String?) {
        Log.d("#####", "Message: $message")
        try {
            conn ?: error("Unknown socket")
            message?.also {
                val msg = adapter.fromJson(it) ?: error("Invalid message")
                val type: String = msg["type"] ?: error("Type not found")
                val topic: String = msg["topic"] ?: error("Topic not found")
                when (type) {
                    "pub" -> {
                        var sendMessage = false
                        pubs[topic]?.forEach { r ->
                            r.get()?.apply {
                                send(message)
                                sendMessage = true
                            }
                        }
                        if (!sendMessage) {
                            Log.d("#####", "Cache message: $message")
                            pubsCache[topic] = message
                        }
                    }
                    "sub" -> {
                        pubs.getOrPut(topic, { mutableListOf() }).add(WeakReference(conn))
                        pubsCache[topic]?.let { cached ->
                            Log.d("#####", "Send cached: $cached")
                            conn.send(cached)
                        }
                    }
                    else -> error("Unknown type")
                }
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

    override fun onStart() {
        Log.d("#####", "Server started")
        connectionLostTimeout = 0
    }

    override fun onError(conn: WebSocket?, ex: Exception?) {
        Log.d("#####", "onError")
        ex?.printStackTrace()
        conn?.let { cleanUpSocket(it) }
    }

    private fun cleanUpSocket(conn: WebSocket) {
        synchronized(pubsLock) {
            pubs.forEach {
                it.value.removeAll { r -> r.get().let { v -> v == null || v == conn } }
            }
        }
    }

    companion object {
        val PORT = 5000 + Random().nextInt(60000)
    }
}

WalletConnectインスタンスを作成する

WalletConnectViewModelMoshi、OkHttpClient、およびWCSessionStoreを作成して挿入します。いくつかのアイテムが必要ですBridgeServer、、Session.Callbackセッション、SessionConfig。そのオブジェクトを生成し、必要な関数を記述します。

@HiltViewModel
class ConnectWalletViewModel @Inject constructor(
    private val moshi: Moshi,
    private val client: OkHttpClient,
    private val storage: WCSessionStore,
): ViewModel() {

    var userWallet = MutableStateFlow("")
    private set

    private var config: Session.Config? = null
    private var session: Session? = null
    private var bridge: BridgeServer? = null
    private var activeCallback: Session.Callback? = null

    init {
        initBridge()
    }

    private fun initBridge() {
        bridge = BridgeServer(moshi).apply {
            onStart()
        }
    }

    private fun resetSession() {
        session?.clearCallbacks()
        val key = ByteArray(32).also { Random().nextBytes(it) }.toHexString(prefix = "")
        config =
            Session.Config(UUID.randomUUID().toString(), "https://bridge.walletconnect.org", key)
        session = WCSession(
            config ?: return,
            MoshiPayloadAdapter(moshi),
            storage,
            OkHttpTransport.Builder(client, moshi),
            Session.PeerMeta(name = "Example App")
        )
        session?.offer()
    }


    fun connectWallet(context: Context) {
        resetSession()
        activeCallback = object : Session.Callback {
            override fun onMethodCall(call: Session.MethodCall) = Unit

            override fun onStatus(status: Session.Status) {
                status.handleStatus()
            }
        }
        session?.addCallback(activeCallback ?: return)
        context.startActivity(Intent(Intent.ACTION_VIEW).apply {
            data = Uri.parse(config?.toWCUri() ?: return)
        })
    }

    fun Session.Status.handleStatus() {
        when (this) {
            Session.Status.Approved -> sessionApproved()
            Session.Status.Closed -> sessionClosed()
            Session.Status.Connected,
            Session.Status.Disconnected,
            is Session.Status.Error,
            -> Log.e("WC Session Status", "handleStatus: $this", )
        }
    }

    private fun sessionApproved() {
        val address = session?.approvedAccounts()?.firstOrNull() ?: return
        /* Provider name*/
        // val walletType = session?.peerMeta()?.name ?: ""
        userWallet.value = address
    }

    private fun sessionClosed() {

    }
}

以上です!ユーザーがいずれかのボタンをクリックしたら、connectWallet関数を呼び出します。接続が成功した場合、sessionApproved関数が呼び出され、UIが更新されます。

What is Keplr Wallet | How to Install and Use Keplr Wallet

Flutter SDK for Building Plugin Packages For The Web3 Wallet

web3wallet-sdk

"Web3 Wallet" SDK for integrating substrate-based blockchains as plugins.

Building a web3plugin dart package

1. Create your plugin repo

create a dart package

flutter create --template=package web3plugin_setheum
cd web3plugin_setheum/

add dependencies in pubspec.yaml

dependencies:
  web3wallet_sdk: ^0.1.0

and install the dependencies.

flutter pub get

2. Build your polkadot-js wrapper

The App use a polkadot-js/api instance running in a hidden webView to connect to remote node.

Example: setheum: https://github.com/Web3SettersClub/web3plugin-setheum/tree/master/lib/js_service_setheum

3. Implement your plugin class

Modify the plugin entry file(eg. web3plugin_setheum.dart), create a PluginFoo class extending Web3walletPlugin:

class PluginSetheum extends Web3walletPlugin {
  /// define your own plugin
}

3.1. override Web3walletPlugin.basic

  @override
  final basic = PluginBasicData(
    name: 'setheum',
    ss58: 25,
    primaryColor: Colors.deepPurple,
    gradientColor: Colors.blue,
    // The `bg.png` will be displayed as texture on a block with theme color,
    // so it should have a transparent or dark background color.
    backgroundImage: AssetImage('packages/web3plugin_setheum/assets/images/bg.png'),
    icon:
        Image.asset('packages/web3plugin_setheum/assets/images/logo.png'),
    // The `logo_gray.png` should have a gray color `#9e9e9e`.
    iconDisabled: Image.asset(
        'packages/web3plugin_setheum/assets/images/logo_gray.png'),
    isTestNet: false,
  );

3.2. override Web3walletPlugin.tokenIcons

Define the icon widgets so the Web3 Wallet App can display tokens of your chain with token icons.

  @override
  final Map<String, Widget> tokenIcons = {
    'SETM': Image.asset(
        'packages/web3plugin_setheum/assets/images/tokens/SETM.png'),
    'SETUSD': Image.asset(
        'packages/web3plugin_setheum/assets/images/tokens/SETUSD.png'),
  };

3.3. override Web3walletPlugin.nodeList

const node_list = [
  {
    'name': 'Setheum Node 1 (Hosted by Setheum Foundation)',
    'ss58': 25,
    'endpoint': 'wss://rpc-newrome.setheum.xyz',
  },
];
  @override
  List<NetworkParams> get nodeList {
    return node_list.map((e) => NetworkParams.fromJson(e)).toList();
  }

3.4. override Web3walletPlugin.getNavItems(BuildContext, Keyring)

Define your custom navigation-item in BottomNavigationBar of Web3 Wallet App. The HomeNavItem.content is the page content widget displayed while your navItem was selected.

  @override
  List<HomeNavItem> getNavItems(BuildContext context, Keyring keyring) {
    return [
      HomeNavItem(
        text: 'Apps',
        icon: SvgPicture.asset(
          'packages/web3plugin_setheum/assets/images/logo.svg',
          color: Theme.of(context).disabledColor,
        ),
        iconActive: SvgPicture.asset(
            'packages/web3plugin_setheum/assets/images/logo.svg'),
        content: SetheumEntry(this, keyring),
      )
    ];
  }

3.5. override Web3walletPlugin.getRoutes(Keyring)

Define navigation route for your plugin pages.

  @override
  Map<String, WidgetBuilder> getRoutes(Keyring keyring) {
    return {
      TxConfirmPage.route: (_) =>
          TxConfirmPage(this, keyring, _service.getPassword),
      CurrencySelectPage.route: (_) => CurrencySelectPage(this),
      AccountQrCodePage.route: (_) => AccountQrCodePage(this, keyring),

      TokenDetailPage.route: (_) => TokenDetailPage(this, keyring),
      TransferPage.route: (_) => TransferPage(this, keyring),

      // other pages
      // ...
    };
  }

3.6. override Web3walletPlugin.loadJSCode() method

Load the polkadot-js/api wrapper you built in step 2.

  @override
  Future<String> loadJSCode() => rootBundle.loadString(
      'packages/web3plugin_setheum/lib/js_service_setheum/dist/main.js');

3.7. override plugin life-circle methods

  • onWillStart(), you may want to prepare your plugin state data here.
  • onStarted(), remote node connected, you may fetch data from network.
  • onAccountChanged(), user just changed account, you may clear cache of the prev account and query data for new account.

Example: setheum

4. Fetch data and build pages

We use https://pub.dev/packages/mobx as the App state management tool. So the directories in a plugin looks like this:

__ lib
    |__ pages (the UI)
    |__ store (the MobX store)
    |__ service (the Actions fired by UI to mutate the store)
    |__ ...

To query data through Web3walletPlugin.sdk.api:

(polkawallet-io/polkawallet_plugin_kusama/lib/service/gov.dart)

  Future<List> queryReferendums() async {
    final data = await api.gov.queryReferendums(keyring.current.address);
    store.gov.setReferendums(data);
    return data;
  }

To query data by calling JS directly:

(polkawallet-io/polkawallet_plugin_kusama/lib/service/gov.dart)

  Future<void> updateBestNumber() async {
    final int bestNumber = await api.service.webView
        .evalJavascript('api.derive.chain.bestNumber()');
    store.gov.setBestNumber(bestNumber);
  }

While we set data to MobX store, the MobX Observer Flutter Widget will rebuild with new data.

5. Run your pages in example/ app

You may want to run an example app in dev while building your plugin pages.

See the setheum example: setheum

Thanks to the www.polkawallet.io Team for this framework used on the Web3 Wallet

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add web3wallet_sdk

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  web3wallet_sdk: ^0.1.1

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:web3wallet_sdk/web3wallet_sdk.dart'; 

example/lib/main.dart

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:web3wallet_sdk/api/types/networkParams.dart';
import 'package:web3wallet_sdk/web3wallet_sdk.dart';
import 'package:web3wallet_sdk/storage/keyring.dart';
import 'package:web3wallet_sdk_example/pages/account.dart';
import 'package:web3wallet_sdk_example/pages/dAppPage.dart';
import 'package:web3wallet_sdk_example/pages/keyring.dart';
import 'package:web3wallet_sdk_example/pages/setting.dart';
import 'package:web3wallet_sdk_example/pages/tx.dart';

import 'pages/staking.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final WalletSDK sdk = WalletSDK();
  final Keyring keyring = Keyring();

  bool _sdkReady = false;

  Future<void> _initApi() async {
    await keyring.init([0, 2]);

    await sdk.init(keyring);
    setState(() {
      _sdkReady = true;
    });
  }

  void _showResult(BuildContext context, String title, res) {
    showCupertinoDialog(
      context: context,
      builder: (BuildContext context) {
        return CupertinoAlertDialog(
          title: Text(title),
          content: SelectableText(res, textAlign: TextAlign.left),
          actions: [
            CupertinoButton(
              child: Text('OK'),
              onPressed: () {
                Navigator.of(context).pop();
              },
            )
          ],
        );
      },
    );
  }

  @override
  void initState() {
    super.initState();
    _initApi();
  }

Android BIP Wallet for Minter

Android BIP Wallet

BIP Wallet TESTNET is an application for buying, selling, and exchanging MNT—digital coin used in the Minter blockchain’s test network.

Featured on Telegram’s official blog, Minter has put a lot of effort into designing a fast, robust, and user-friendly mobile wallet.

Tired of having to memorize those long strings of symbols they call blockchain addresses? Quit that! With BIP wallet, you can transfer funds to an e-mail address and even a username. What’s more, it takes only five seconds for a transaction to be completed.

Download

Latest version always available at Google Play,

Documentation

Javadoc available in code comments

Build

1. Clone repository

git clone https://github.com/MinterTeam/minter-android-wallet.git

// see latest stable release tag
git checkout ${latest.tag}

2. Install Android SDK (if not installed yet)

3. Build via gradle

3.1 Create keystore for app signing

First, locate your JDK path and add $JAVA_HOME/bin directory to your $PATH variable

export PATH=$PATH:/path/to/jdk/

Default JDK locations:

  • Windows: C:\Program Files\Java\jre7\bin
  • macOS: /Library/Java/JavaVirtualMachines/jdk-$VERS.jdk

Second. Create keystore file via keytool

Example:

keytool -genkey -v -keystore wallet.keystore -alias wallet_alias -keyalg RSA -keysize 2048 -validity 10000

Or via Android Studio. See google examples: link

Third. Put keystore values to $HOME/.gradle/gradle.properties

minter_key_alias=$KEY_ALIAS_YOU_WERE_SET
minter_key_password=$KEY_PASSWORD_YOU_WERE_SET
minter_key_store_file=$KEY_STORE_FILE_PATH_YOU_WERE_SET
minter_key_store_password=$KEY_STORE_FILE_PASSWORD_YOU_WERE_SET

3.2 Assembling

cd /path/to/minter-android-wallet

// Testnet flavor
./gradlew :clean :app:assembleNetTestRelease

// Mainnet flavor
./gradlew :clean :app:assembleNetMainRelease

Built apk file will be stored at:

  • For testnet: app/build/outputs/apk/netTest/release
  • For mainnet: app/build/outputs/apk/netMain/release

4. Testing

Unit tests:

./gradlew :app:testNetTestDebugUnitTest

UI test (emulator or physical device required)

./gradlew :app:connectedNetTestDebugAndroidTest
