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

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.

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:

Ethereum Ecosystem Overview | Top 200 Project Built on Ethereum (ETH)

In this article, you'll learn Ethereum, Ethereum Ecosystem Overview | Top 200 Project Built on Ethereum (ETH)

1. What is Ethereum?

Ethereum is a blockchain-based computing platform that enables developers to build and deploy decentralized applications—meaning not run by a centralized authority. You can create a decentralized application for which the participants of that particular application are the decision-making authority.

Ethereum Features

  • Ether: This is Ethereum’s cryptocurrency.
  • Smart contracts: Ethereum allows the development and deployment of these types of contracts.
  • Ethereum Virtual Machine: Ethereum provides the underlying technology—the architecture and the software—that understands smart contracts and allows you to interact with it.
  • Decentralized applications (Dapps): A decentralized application is called a Dapp (also spelled DAPP, App, or DApp) for short. Ethereum allows you to create consolidated applications, called decentralized applications.
  • Decentralized autonomous organizations (DAOs): Ethereum allows you to create these for democratic decision-making.

These are Ethereum’s essential features. Before going deep into the Ethereum tutorial, let’s discuss each of these features in more detail.

1.1. Ether

Ether (ETH) is Ethereum’s cryptocurrency. It is the fuel that runs the network. It is used to pay for the computational resources and the transaction fees for any transaction executed on the Ethereum network. Like Bitcoins, ether is a peer-to-peer currency. Apart from being used to pay for transactions, ether is also used to buy gas, which is used to pay for the computation of any transaction made on the Ethereum network.

Also, if you want to deploy a contract on Ethereum, you will need gas, and you would have to pay for that gas in ether. So gas is the execution fee paid by a user for running a transaction in Ethereum. Ether can be utilized for building decentralized applications, building smart contracts, and making regular peer-to-peer payments.

1.2. Smart Contracts

Smart contracts are revolutionizing how traditional contracts work, which is why you need to use the tutorial to become more familiar with them. A smart contract is a simple computer program that facilitates the exchange of any asset between two parties. It could be money, shares, property, or any other digital asset that you want to exchange. Anyone on the Ethereum network can create these contracts. The contract consists primarily of the terms and conditions mutually agreed on between the parties (peers).

The smart contract’s primary feature is that once it is executed, it cannot be altered, and any transaction done on top of a smart contract is registered permanently—it is immutable. So even if you modify the smart contract in the future, the transactions correlated with the original contract will not get altered; you cannot edit them.

The verification process for the smart contracts is carried out by anonymous parties in the network without the need for a centralized authority, and that’s what makes any smart contract execution on Ethereum a decentralized execution.

The transfer of any asset or currency is done in a transparent and trustworthy manner, and the identities of the two entities are secure on the Ethereum network. Once the transaction is successfully done, the accounts of the sender and receiver are updated accordingly, and in this way, it generates trust between the parties.

  • Smart Contracts Vs. Traditional Contract Systems

In conventional contract systems, you sign an agreement, then you trust and hire a third party for its execution. The problem is that in this type of process, data tampering is possible. With smart contracts, the agreement is coded in a program.

A centralized authority does not verify the result; it is confirmed by the participants on the Ethereum blockchain-based network. Once a contract is executed, the transaction is registered and cannot be altered or tampered, so it removes the risk of any data manipulation or alteration.

Let’s take an example in which someone named Zack has given a contract of $500 to someone named Elsa for developing his company’s website. The developers code the agreement of the smart contract using Ethereum’s programming language.

The smart contract has all the conditions (requirements) for building the website. Once the code is written, it is uploaded and deployed on the Ethereum Virtual Machine (EVM).

EVM is a runtime compiler to execute a smart contract. Once the code is deployed on the EVM, every participant on the network has a copy of the contract. When Elsa submits the work on Ethereum for evaluation, each node on the Ethereum network will evaluate and confirm whether the result given by Elsa has been done as per the coding requirements.

Once the result is approved and verified, the contract worth $500 will be self-executed, and the payment will be paid to Elsa in ether. Zack’s account will be automatically debited, and Elsa will be credited with $500 in ether.

1.3. Ethereum Virtual Machine

EVM, as mentioned above in this Ethereum tutorial, is designed to operate as a runtime environment for compiling and deploying Ethereum-based smart contracts. EVM is the engine that understands the language of smart contracts, which are written in the Solidity language for Ethereum. EVM is operated in a sandbox environment—basically, you can deploy your stand-alone environment, which can act as a testing and development environment. You can then test your smart contract (use it) “n” number of times, verify it, and once you are satisfied with the performance and the functionality of the smart contract, you can deploy it on the Ethereum main network.

Any programming language in the smart contract is compiled into the bytecode, which the EVM understands. This bytecode can be read and executed using the EVM. Solidity is one of the most popular languages for writing a smart contract. Once you write your smart contract in Solidity, that contract gets converted into the bytecode and gets deployed on the EVM, thereby guaranteeing security from cyberattacks.

a. How Does EVM Work?

Suppose person A wants to pay person B 10 ethers. The transaction will be sent to the EVM using a smart contract for a fund transfer from A to B. To validate the transaction; the Ethereum network will perform the proof-of-work consensus algorithm.

The miner nodes on Ethereum will validate this transaction—whether the identity of A exists or not, and if A has the requested amount to transfer. Once the transaction is confirmed, the ether will be debited from A’s wallet and will be credited to B’s wallet, and during this process, the miners will charge a fee to validate this transaction and will earn a reward.

All the nodes on the Ethereum network execute smart contracts using their respective EVMs.

b. Proof of Work

Every node in the Ethereum network has:

  • The entire history of all the transactions—the entire chain
  • The history of the smart contract, which is the address at which the smart contract is deployed, along with the transactions associated with the smart contract
  • The handle to the current state of the smart contract

The goal of the miners on the Ethereum network is to validate the blocks. For each block of a transaction, miners use their computational power and resources to get the appropriate hash value by varying the nonce. The miners will vary the nonce and pass it through a hashing algorithm—in Ethereum, it is the Ethash algorithm.

This produces a hash value that should be less than the predefined target as per the proof-of-work consensus. If the hash value generated is less than the target value, then the block is considered to be verified, and the miner gets rewarded.

When the proof of work is solved, the result is broadcast and shared with all the other nodes to update their ledger. If other nodes accept the hashed block as valid, then the block gets added to the Ethereum main blockchain, and as a result, the miner receives a reward, which as of today stands at three ethers. Plus, the miner gets the transaction fees that have been generated for verifying the block. All the transactions that are aggregated in the block—the cumulative transaction fees associated with all the transactions are also rewarded to the miner.

c. Proof of Stake

In Ethereum, a process called proof of stake is also under development. It is an alternative to proof of work and is meant to be a solution to minimize the use of expensive resources spent on mining using proof of work. In proof of stake, the miner—who is the validator—can validate the transactions based on the number of crypto coins he or she holds before actually starting the mining.

So, based on the accumulation of crypto coins the miner has beforehand, he or she has a higher probability of mining the block. However, proof of stake is not widely used as of now compared to proof of work.

d. Gas

Just like we need fuel to run a car, we need gas to run applications on the Ethereum network. To perform any transaction within the Ethereum network, a user must make a payment, in this case paying out ethers, to get a transaction done, and the intermediary monetary value is called gas.

On the Ethereum network, gas is a unit that measures the computational power required to run a smart contract or a transaction. So, if you must do a transaction that updates the blockchain, you would have to shell out gas, and that gas costs ethers.

In Ethereum, the transaction fees are calculated using a formula (see screenshot below). For every transaction, there is gas and its correlated gas price. The transaction fees equal the amount of gas required to execute a transaction multiplied by the gas price. “Gas limit” refers to the amount of gas used for the computation and the amount of ether a user is required to pay for the gas.

Below is a screenshot from the Ethereum network showing the transaction cost. You can see for this particular transaction, the gas limit was 21,000, the gas used by the transaction was 21,000, and the gas price was 21 Gwei, which is the lowest denomination of ether. So, 21 Gwei * 21,000 gave the actual transaction fees: 0.000441 ethers, or about 21 cents as of today. As mentioned, the transaction fee goes to the miner, who has validated the transaction.

To understand the gas limit and price, let’s consider an example using a car. Suppose your vehicle has a mileage of 10 kilometers per liter and petrol costs $1 per liter. Under these parameters, driving a car for 50 kilometers would cost you five liters of petrol, which is worth $5. Similarly, to perform an operation or to run code on Ethereum, you need to obtain a certain amount of gas, like petrol, and the gas has a per-unit price, called gas price.

If the user provides less than the amount of gas to run an operation, then the process will fail, and the user will be given the message “out of gas.” And Gwei, as noted above, is the lowest denomination of ether used for measuring a unit of a gas price.

1.4. Decentralized Applications (Dapps)

Let’s compare decentralized applications with traditional applications. When you log in to Twitter, for example, a web application gets displayed that is rendered using HTML. The page will call an API to access your data (your information), which is centrally hosted. It’s a simple process: your front end executes the backend API, and the API goes and fetches your data from a centralized database.

If we transform this application into a decentralized application when you log in, the same web application gets rendered, but it calls a smart contract-based API to fetch the information from the blockchain network. So, the API is replaced by a smart contract interface, and the smart contract will bring the data from the blockchain network, which is its back end.

That blockchain network is not a centralized database; it’s a decentralized network in which the participants of the network (the miners) validate (verify) all the transactions that are happening using the smart contract on the blockchain network. So, any transaction or action happening on a Twitter-type application that has now been transformed will be a decentralized transaction.

A Dapp consists of a backing code that runs on a distributed peer-to-peer network. It is a software designed to work in the Ethereum network without being controlled by a centralized system, as mentioned, and that is the primary difference: it provides direct interaction between the end-users and the decentralized application providers.

An application qualifies as a Dapp when it is open-source (its code is on Github), and it uses a public blockchain-based token to run its applications. A token acts as fuel for the decentralized application to run. Dapp allows the back end code and data to be decentralized, and that is the primary architecture of any Dapp.

1.5. Decentralized Autonomous Organizations (DAOs)

A DAO is a digital organization that operates without hierarchical management; it works in a decentralized and democratic fashion. So basically, a DAO is an organization in which the decision-making is not in the hands of a centralized authority but preferably in the hands of certain designated authorities or a group or designated people as a part of an authority. It exists on a blockchain network, where it is governed by the protocols embedded in a smart contract, and thereby, DAOs rely on smart contracts for decision-making—or, we can say, decentralized voting systems—within the organization. So, before any organizational decision can be made, it must go through the voting system, which runs on a decentralized application.

Here’s how it works. People add funds through the DAO because the DAO requires funding in order to execute and make decisions. Based on that, each member is given a token that represents that person’s percentage of shares in the DAO. Those tokens are used to vote in the DAO, and the proposal status is decided based on the maximum votes. Every decision within the organization must go through this voting process.

While some Ethereum dApps may appear similar to traditional web applications from a user perspective, dApps are capable of operating and transacting in a peer-to-peer fashion without the need for a central authority. Ethereum continues to be the most widely adopted platform of its kind, Ethereum blockchain remains the second largest, in large part because of the project’s success in attracting developers to build dApps on its network.

Steem: The Blockchain for Smart Media tokens (SMTs) and Dapps

Steem - The Blockchain That Will Tokenize The Web

Welcome to the official repository for Steem, the blockchain that will revolutionize the web, and soon the blockchain for Smart Media Tokens!

Steem is the first blockchain which introduced the "Proof of Brain" social consensus algorithm for token allocation.

Being one of the most actively developed blockchain projects currently in existence, it's become fertile soil for entrepreneurial pursuits. It has also become home for many cryptocurrency centric projects.

Steem aims to be the preferred blockchain for dApp development with Smart Media Tokens at its core. With SMTs, everyone can leverage the power of Steem.

Originally, Steem was announced on the Bitcointalk forum prior to the start of any mining. (Steem is currently not mineable)


  • Free Transactions (Resource Credits = Freemium Model)
  • Fast Block Confirmations (3 seconds)
  • Time Delay Security (Vested Steem & Savings)
  • Hierarchical Role Based Permissions (Keys)
  • Integrated Token Allocation
  • Smart Media Tokens (soon)
  • Lowest Entry-Barrier for User Adoption in the market
  • Dozens of dApps already built on Steem and many more to come

Technical Details

  • Currency symbol STEEM
  • SBD - Steem's very own stable coin with a one-way peg
  • Delegated Proof-of-Stake Consensus (DPOS)
  • 10% APR inflation narrowing to 1% APR over 20 years
    • 75% of inflation to "Proof of Brain" social consensus algorithm.
    • 15% of inflation to stakeholders.
    • 10% of inflation to block producers.


Getting started with Steem is fairly simple. You can either choose to use docker-images, build with docker manually or build from source directly. All steps have been documented and while many different OS are supported, the easiest one is Ubuntu 16.04.


Just want to get up and running quickly? We have pre-built Docker images for your convenience. More details are in our Quickstart Guide.


We strongly recommend using one of our pre-built Docker images or using Docker to build Steem. Both of these processes are described in the Quickstart Guide.

But if you would still like to build from source, we also have build instructions for Linux (Ubuntu LTS) and macOS.

Dockerized P2P Node

To run a p2p node (ca. 2GB of memory is required at the moment):

docker run \
    -d -p 2001:2001 -p 8090:8090 --name steemd-default \

docker logs -f steemd-default  # follow along

Dockerized Full Node

To run a node with all the data (e.g. for supporting a content website) ca. 14GB of memory, and growing, is required:

docker run \
    --env USE_WAY_TOO_MUCH_RAM=1 --env USE_FULL_WEB_NODE=1 \
    -d -p 2001:2001 -p 8090:8090 --name steemd-full \

docker logs -f steemd-full

CLI Wallet

We provide a basic cli wallet for interfacing with steemd. The wallet is self-documented via command line help. The node you connect to via the cli wallet needs to be running the account_by_key_api, condenser_api, and needs to be configured to accept WebSocket connections via webserver-ws-endpoint.


See doc/devs/ for test build targets and info on how to use lcov to check code test coverage.


Config File

Run steemd once to generate a data directory and config file. The default location is witness_node_data_dir. Kill steemd. It won't do anything without seed nodes. If you want to modify the config to your liking, we have two example configs used in the docker images. ( consensus node, full node ) All options will be present in the default config file and there may be more options needing to be changed from the docker configs (some of the options actually used in images are configured via command line).

Seed Nodes

A list of some seed nodes to get you started can be found in doc/seednodes.txt.

This same file is baked into the docker images and can be overridden by setting STEEMD_SEED_NODES in the container environment at docker run time to a whitespace delimited list of seed nodes (with port).

Environment variables

There are quite a few environment variables that can be set to run steemd in different ways:

  • USE_WAY_TOO_MUCH_RAM - if set to true, steemd starts a 'full node'
  • USE_FULL_WEB_NODE - if set to true, a default config file will be used that enables a full set of API's and associated plugins.
  • USE_NGINX_FRONTEND - if set to true, this will enable an NGINX reverse proxy in front of steemd that proxies WebSocket requests to steemd. This will also enable a custom healthcheck at the path '/health' that lists how many seconds away from current blockchain time your node is. It will return a '200' if it's less than 60 seconds away from being synced.
  • USE_MULTICORE_READONLY - if set to true, this will enable steemd in multiple reader mode to take advantage of multiple cores (if available). Read requests are handled by the read-only nodes and write requests are forwarded back to the single 'writer' node automatically. NGINX load balances all requests to the reader nodes, 4 per available core. This setting is still considered experimental and may have trouble with some API calls until further development is completed.
  • HOME - set this to the path where you want steemd to store it's data files (block log, shared memory, config file, etc). By default /var/lib/steemd is used and exists inside the docker container. If you want to use a different mount point (like a ramdisk, or a different drive) then you may want to set this variable to map the volume to your docker container.

PaaS mode

Steemd now supports a PaaS mode (platform as a service) that currently works with Amazon's Elastic Beanstalk service. It can be launched using the following environment variables:

  • USE_PAAS - if set to true, steemd will launch in a format that works with AWS EB. Containers will exit upon failure so that they can be relaunched automatically by ECS. This mode assumes USE_WAY_TOO_MUCH_RAM and USE_FULL_WEB_NODE, they do not need to be also set.
  • S3_BUCKET - set this to the name of the S3 bucket where you will store shared memory files for steemd in Amazon S3. They will be stored compressed in bz2 format with the file name blockchain-$VERSION-latest.tar.bz2, where $VERSION is the release number followed by the git short commit hash stored in each docker image at /etc/steemdversion.
  • SYNC_TO_S3 - if set to true, the node will function to only generate shared memory files and upload them to the specified S3 bucket. This makes fast deployments and autoscaling for steemd possible.

System Requirements

For a full web node, you need at least 110GB of disk space available. Steemd uses a memory mapped file which currently holds 56GB of data and by default is set to use up to 80GB. The block log of the blockchain itself is a little over 27GB. It's highly recommended to run steemd on a fast disk such as an SSD or by placing the shared memory files in a ramdisk and using the --shared-file-dir=/path command line option to specify where. At least 16GB of memory is required for a full web node. Seed nodes (p2p mode) can run with as little as 4GB of memory with a 24 GB state file. Any CPU with decent single core performance should be sufficient. Steemd is constantly growing. As of August 2017, these numbers were accurate, but you may find you need more disk space to run a full node. We are also constantly working on optimizing Steem's use of disk space.

On Linux use the following Virtual Memory configuration for the initial sync and subsequent replays. It is not needed for normal operation.

echo    75 | sudo tee /proc/sys/vm/dirty_background_ratio
echo  1000 | sudo tee /proc/sys/vm/dirty_expire_centisecs
echo    80 | sudo tee /proc/sys/vm/dirty_ratio
echo 30000 | sudo tee /proc/sys/vm/dirty_writeback_centisecs

Web3 React: Building Modern Ethereum dApps

web3-react (beta)


This is a hosted version of packages/example.


Experimental Connectors  Not stable

Getting Started

  • yarn
  • yarn bootstrap
  • yarn start

In addition to compiling each package in watch mode, this will also spin up packages/example on localhost:3000.

Running Tests

  • yarn test --watch


This version of web3-react is still in beta, so unfortunately documentation is pretty sparse at the moment. The packages/example, TSDoc comments, and the source itself are the best ways to get an idea of what's going on. More thorough documentation is a priority as development continues!

Adding Connectors

If you're interested in using web3-react with a wallet that doesn't have an "official" connector package, you're in luck! This library was designed to be highly modular, and you should be able to draw inspiration from the existing connectors to write your own! That code can live inside your codebase, or even be published as a standalone package. From time to time, if there's sufficient interest and desire, PRs adding new connectors may be accepted, but this should be brought up in an issue or discussion beforehand.

Upgrading from v6

While the internals of web3-react have changed fairly dramatically between v6 and v8, the hope is that usage don't have to change too much when upgrading. Once you've migrated to the new connectors and state management patterns, you should be able to use the hooks defined in @web3-react/core, in particular useWeb3React (or usePriorityWeb3React), as more or less drop-in replacements for the v6 hooks. The big benefit in v8 is that hooks are now per-connector, as opposed to global, so no more juggling between connectors/multiple roots!

Useful Commands

Add a dependency

  • yarn lerna add <DEPENDENCY> --scope <PACKAGE>

Remove a dependency

  • Delete the relevant package.json entry

Because of a lerna bug, it's not possible to prune yarn.lock programmatically, so regenerate it manually:

  • yarn lerna exec "rm -f yarn.lock" --scope <SUBPACKAGE>
  • yarn clean --scope <SUBPACKAGE>
  • yarn bootstrap

Web3 React: Building Modern Ethereum dApps

TDN: A Micro-framework for Building Decentralized Applications

TDN: Let data transfer safely, make the network stable, secure, and highly available.

As the network interconnection, TDN includes peer-to-peer, centralized gateway, proxy & relay service, LAN, RPC, Near, etc.

As the framework of decentralized applications, TDN uses the Layer and Group models. We built this framework because we feel that the blockchain is very limited. If you want a more open and free distributed application development technology, and Pluggable, lightweight application framework, TDN can satisfy you.


  • install lastest Rust and cd ./tdn
  • cargo run --example simple Congratulation, you are running a trusted distributed network :)

more sample


  • Support different data structures
  • Support different consensus algorithms
  • Support different permission mechanisms
  • Support different account systems
  • Applications can communicate with others
  • Trust can be passed on and accumulated

4-type Applications

TDN can build 4-type network for applications. Use feature to control. (Tip: one group, is one chain, is one application)

  • single. Support only one group, and no layers. Like Bitcoin.
  • std (default). Support only one group, and multiple layers (cross-chain, Interactive with other groups).
  • multiple. Support many groups (in one runtime, support many applications), and no layers. Like Ethereum.
  • full. Support many groups, and multiple layers.


TDN with future

TDN Groups And Layers

Pluggable library

  • tdn-did decentralized identity.
  • tdn-storage Storage library, include Local file, Local db, Distributed db, Decentralized db.
  • tdn-permission Group permission library, include permissioned & permissionless group algorithm.

Projects used it

  • ESSE - full-type - An open source encrypted peer-to-peer system. Own data, own privacy.
  • group-chat - multiple-type - Group Chat for ESSE and TDN Ecological.

For more information, please visit:

Core QA

  1. What is Layers & Groups? Simply Group is application, one application is one group, Layer is communication between apps. In the Group, users can define everything. The Layer is divided into upper and lower, upper is this application depends on others, lower is others depends on this. If app is an independent application that does not interact with other applications, then you can completely ignore Layer.
  2. Different consensus? Consensus is expensive. Not all applications require global consensus to be used. Local consensus can speed up the usability of applications. Local consensus can be different. Users can define self-consensus in different applications. The results of the consensus can also be sent to different applications through the layer. In this way, the consensus results can be passed to the upper layer. After the upper layer consensus is obtained, a larger range and stronger consensus irreversible result can be formed.
  3. Different permission? Why do we need a different permission mechanism? Because in different applications, some applications require an open permissionless environment, such as Bitcoin, and some require a permissioned environment. For example, We built a synchronization which is distributed between my own devices is inaccessible to outsiders. At the same time, Layer supports applications in different permission environments, allowing data interaction.
  4. Different block & transaction data structure? Similarly, different applications have completely different data structures. Therefore, in the TDN, we use a common byte stream format. Users can customize the data format of the application. The communication with the TDN is only serialization and deserialization.
  5. Different account system? In the TDN, there will be a default p2p network address (PeerId) in the p2p system. The user can use the PeerId to replace the ip address. The TDN will search the PeerId in the network and establish a connection. At the same time, the user can also Fully customize the account model and connection verification method of the application.

⛓ Hook for fast network switching or getting info about current network. To change the current network, set the target chainId to switchNetwork function. If the user does not have the target network in the wallet, it will automatically ask permission to add it to the wallet.


import { useChain } from "react-moralis";

function Chains() {
  const { switchNetwork, chainId, chain, account } = useChain();
  return (
      <button onClick={() => switchNetwork("0x1")}>Switch to Ethereum</button>
      <p>Current chainId: {chainId}</p>


💰 Gets the price nominated in the native token and usd for a given token contract address


  • chain (optional): The blockchain to get data from. Valid values are listed on the intro page in the Transactions and Balances section. Default value: current chain (if the chain is not supported it will use the Eth chain).
  • address (optional): A user address (i.e. 0x1a2b3x...). If specified, the user attached to the query is ignored and the address will be used instead.
  • exchange (optional): The factory name or address of the token exchange. Possible exchanges, for different chains are: ETH mainnet: uniswap-v3, sushiswap, uniswap-v2, BSC mainnet: pancakeswap-v2, pancakeswap-v1. Polygon mainnet: quickswap. If no exchange is specified, all exchanges are checked (in the order as listed above) until a valid pool has been found. Note that this request can take more time. So specifying the exchange will result in faster responses most of the time.
  • to_block (optional): Returns the price for a given blocknumber (historical price-data).


import { useTokenPrice } from "react-moralis";

const TokenPrice = () => {
  const { fetchTokenPrice, data: formattedData, error, isLoading, isFetching } = useTokenPrice({ address: "0x1f9840...1f984", chain: "eth" });

Ethereum Boilerplate: React Components and Hooks for fast Building dApps

How to Create Defi Decentralized Apps (dApps) on Etherium Using React

React Native Defi Decentralized Applications(dApps) Uygulaması

Bu proje, Ethereum network üzerinde DeFI(Decentralized Finance) dApps P2P (Peer-to-Peer) para transferi yapan bir app geliştirmesi yapmamızı sağlar.

Örnek bir akıllı sözleşme, bu sözleşme için bir test, bu sözleşmeyi dağıtan örnek bir komut dosyası ve yalnızca kullanılabilir hesapları listeleyen bir görev uygulaması örneği ile birlikte gelir.

Aşağıdaki yönergelerle uygulamayı çalıştırmayı deneyin:

  • Uygulamada öncelikle hardhat kullanarak blockchain network komutla "npx hardhat node" oluşturmalısınız
  • Uygulamayı kullandığınız platform iOS ise "yarn ios yada npm run ios" android ise "yarn android yada npm run android" komutlarıyla çalıştırabilirsiniz.

Hardhat için kullanabileceğiniz komutlar :

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
node scripts/sample-script.js
npx hardhat help
