Metamask: how to distribute intelligent contracts on Zksync was testnet using Remix and Metamask
As a developer, the launch of intelligent contracts on testnets is a crucial step in the test and validation of their functionality before distributing them into production environments. A popular choice for this purpose is the testnet of the Zksync era, which offers a safe and reliable test environment for Blockchain applications.
In this article, we will guide you through the process of distribution of intelligent contracts on Zksync was testnet using Remix with Metamask as an injected supplier.
What is Metamask?
Metamask is a famous Ethereum -based portfolio that allows users to interact with the Ethereum network. It also supports decentralized applications (APPS) and non -whistling (NFT) token through its integrated DAP interface, making it an essential tool for developers who wish to test intelligent contracts on various blockchain environments.
Zksync was testnet
Zksync was testnet is a testnet that allows developers to test their implementations of intelligent contracts without risking the funds of the real world. It is a completely functional Ethereum network with the same Mainnet architecture, but with some key differences:
- Testnet uses a modified Ethereum version (for example 4.x) instead of the latest version.
- The testnet reduced computational resources compared to the mainnet.
- The testnet has fewer intelligent contracts available for tests.
Remix and Metamask
To distribute intelligent contracts on Zksync was testnet using remix with Metamask, you will need:
- Remix : a popular web -based development environment for the construction and distribution of DAPP. You can download the latest version of Remix from the official website.
- Metamask : the Ethereum -based portfolio that we mentioned previously.
Here is a step-by-step guide to distribute intelligent contracts on Zksync was Testnet using Remix with Metamask:
Step 1: Set up metamask and remix
Install Metamask and Remix on the machine, as described in the official documentation.
Step 2: Install Zksync-Erasertest.js
To use Thezksync testnet Era, you will have to install the ZKSync-Erasertest.js package. You can do it using npm or yarn:
Bash
NPM Install Zksync-Erasertestnet-Js
`
Step 3: Create a new contract
Create a new contract on Remix that will be distributed on Zksync era testnet. Follow the official Remix documentation to create a new contract.
For example, if you want to distribute a simple intelligent contractMycontractwith two variables, you can do it:
Javascript
Import {Contract} from ‘@Remix-Starter/APP-CONNECTOR’;
Import {ZksynceSertestnetjs} from “Zksync-Erasertestnet-Js”;
Const MyContract = {
Init: Async (Context) => {
// Initialize the variables of the contract
Contest.state.myvar = ‘Hello, world!’;
return true;
},
};
Const Contract = new contract (MyConttract);
// Distribute the contract to Zksync was testnet
Console.log (‘Distribution of the contract to Zksync was testnet’);
`
Step 4: Use Metamask with Remix
After creating a new intelligent contract and distributed on Zksync was testnet, he uses Metamask with remix as an injected supplier. You can do it with:
- Opening of the remix in your web browser
- By clicking on "Distribute" or "distribute the contract"
- Selection ofzksycesertestnet-js` from the provider drop-down list
Metamask will then inject the address of the contract and in the distribution process, allowing you to interact with the distributed contract.
Step 5: Test your intelligent contract
With Metamask and Remix configured correctly, now you can test your intelligent contract on Zksync was testnet. You can use the DAP interface in Remix or third -party tools such as OPENZAPPELIN TESTRPC to interact with the intelligent contract.
