Web3 OpenAPI Compliant Service Generator for Solidity Smart Contracts

Web3j Open API

Web3j-OpenAPI is a OpenAPI client and server generator from Solidity smart contracts. it provides a way to interact with the Ethereum blockchain via simple and intuitive HTTP requests, abstracting the coding layer. These interactions can be done using :

  • Plain HTTP requests
  • Via the Swagger-UI, which is generated with every project
  • A client application using the webj3-openapi-client implementation

The workflow can be summed in the following steps:

  • Writing a Solidity smart contract
  • Generating the corresponding OpenAPI project using Web3j-OpenAPI
  • Running the generated project as a standalone server
  • Sending HTTP requests using Swagger-UI, client application or Curl request.

Getting started with Web3j-OpenAPI

To generate an OpenAPI project using the Web3j-OpenAPI generator, you need to have the Epirus-CLI installed on your machine (Note - the Epirus CLI has replaced the Web3j CLI). It’s easy to do (for Windows instructions head here):

$ curl -L get.epirus.io | sh

Create a Hello World project

To create a base OpenAPI project using a Hello World contract, run the following :

$ epirus openapi new

You can also generate a Web3j-OpenAPI project using the Web3j-OpenAPI-gradle-plugin.

Configure the project

After having the generated project, you can use the Epirus-CLI to run it using the following command (Note: You will need to create an Epirus Account).

$ epirus login
$ epirus run rinkeby|ropsten

Alternatively, you can configure your application with the following environment variables:

$ export WEB3J_ENDPOINT=<link_to_your_Ethereum_node>
$ export WEB3J_PRIVATE_KEY=<your_private_key>
$ export WEB3J_OPENAPI_HOST=localhost
$ export WEB3J_OPENAPI_PORT=9090

Run the project

If you aren't using the Epirus-CLI, you may run the project using the following Gradle target:

$ cd <project_folder>
$ ./gradlew run

Then, you should be seeing the server logs.

Interact with the project

SwaggerUI

The easiest way to interact with the generated project is via the generated Swagger-UI which can be found on http://<host>:<port>/swagger-ui.

Web3j-OpenAPI client

Also, you can use our client implementation via adding the following dependency to your project:

dependencies {
    implementation "org.web3j.openapi:web3j-openapi-client:4.7.1"
}

Then, within the application:

val service = ClientService("http://localhost:9090")
val app = ClientFactory.create(<AppNameApi>::class.java, service)

// Then you have access to all the API resources
val receipt = app.contracts.contractName.deploy()

println("Deployment receipt: ${receipt.contractAddress}")

// ...

What makes a smart contract a perfect solution for my business?

A smart contract enables you to achieve various feats that seem unfathomable. Also, you get to protect the information of your enterprise in the best possible manner. When you have the power to expand your operation, you should be wise enough to choose the most appropriate solution. There are times when you have to think of something exemplary, it also gives you more about the perfection of the tools. At such a time, you need to have a proper understanding of the features and get things planned in a permanent fashion.

It does not matter which domain you are related to, you get to think about the possible solutions from every domain. Also, you get to manage various other tasks that seem very difficult otherwise. Before you introduce this ledger-based framework in your firm, you need to ready for the outcomes. Every time you come across a decentralized network, you start to pave way for something more dynamic. This gives you the power to react on time and with more efficacy for the long term. Also, you get to review the overall working with a set of proficient developers.

Whether you directly connect with the blockchain or not, your business draws a large number of benefits from the smart contracts. The very core of this solution enables you to create a fitting structure around every company. Also, you get to come with a prominent fix that empowers the proponents of your project. The vision of your investors gets broadened and you get the insights to envision things properly. Every time you do it, you get things worked up properly, you get to maintain a proper flux of funds. In this way, your business gets whatever you want in a very short duration.

How should I develop and implement smart contracts in my business?

By introducing this solution, you prepare your startup to scale up the steps of success. Also, it helps your business overcome all types of issues whether they are temporary in nature or permanent. You need to understand the predilection of every course of action so there is never any obstacle in the way. Moreover, it becomes very easy for your organization to spread its wings because it has befitting tools to support its working. This may also happen in with support structures that ease the expansion of business in a very lesser time.

In every industry, there is a scope of decentralization and you can make it even easier through a string of services. All the crypto-based programs help you get closer to the customers with a reliable method of payment. With this structure, it is possible for every business to do something exceptional. Whether you want it or not, you get to work on many expeditionary campaigns. Also, you help others expand the work and things can get more explicable flawlessly. The working of this solution gives you a high quantum of accuracy in every possible manner.

The prospects of your company can get much better and promising because you have a lesser number of agents deployed. You might find these differences odd, but they can highly impact the development as well as transactions. When you want to touch base with your team or some consultants, you get a better idea about the entire thing. Also, that happens without having you wasting your time. There could be subtle errors in the initial phases of the development of tokens or any other distributed ledger. If decentralization is at the core, you need to have more potential to conceptualize new methods.

How should I find professionals who could develop custom-built smart contracts?

You can certainly get such experts but the search has to be very thorough in nature. Also, the whole thing has to be planned to the hilt and things could be working seamlessly. When you get things working at an impressive pace, you might lack clear objects. Even if there is a projected solution for some problems, you must not employ them before proper rounds of review. This approach gives you satisfactory results in every domain and keeps you one step ahead when it comes to getting what you precisely need.

It is vital that you work with people who have an idea about what’s happening in your firm. By working with such people, you get more certainty in every step sans wasting a large quantum of resources or time. You might be able to find some other options but they all resort to decentralization in the end. The best way to implement this solution is to give more time to every single process through many methods. Also, you need to get things aligned with a proper solution and help the developers give shape to their visions.

Upshot

With the experts of Coin Developer India, it is possible for every startup to get a bespoke smart contract.
