Metamask: How to provide intelligent contracts on the ZKKSYNC -A -Test with Remix and Metamask
As a developer, the introduction of intelligent contracts on tests is a crucial step when testing and validating your functions before they are provided in production environments. A popular choice for this purpose is the ZKKSYNC ERA, which offers a safe and reliable test environment for blockchain applications.
In this article, we conduct you through the process of providing intelligent contracts on the ZKSync ERA testnet with a remix with metamask as a injected provider.
What is metamask?
Metamask is a popular in Ethereum-based wallet with which users can interact with the Ethereum network. It also supports decentralized applications (DAPPS) and non-fungial tokens (NFTS) via the integrated DAPP interface and makes it a significant tool for developers who want to test intelligent contracts in various blockchain environments.
zksync era testnet
The ZKSync ERA testnet is a testnet with which developers can test their smart contract simplifications without risking real means. It is a fully functional Ethereum network with the same architecture as the Mainnet, but differentiated with some important ones:
- The testnet uses a modified Ethereum version (e.g. 4.x) instead of the latest version.
- The test network has reduced the calculation resources compared to the Mainset.
- The testnet has less intelligent contracts for testing.
remix and metamast
In order to provide intelligent contracts on the ZKKSync -A -Test with a remix with metamask, you need:
- Remix : A popular web -based development environment for building and providing DAPPS. You can download Remix’s latest version from the official website.
- Metamask
: The wallet based in Ethereum, which we mentioned earlier.
Here you will find a step-by-step instructions for providing intelligent contracts on the ZKKSYNC-ERA test with a remix with metamask:
Step 1: Set up Metamask and Remix
Install Metamask and Remix on your computer, as described in the official documentation.
Step 2: Install ZKSync-erasertestnet.js
To use ThezkKSync ERA testnet, you must install the “ZKKSYNC-ERASERSTET.JS” package. You can do this with NPM or yarn:
`Bash
NPM Install ZKSync Erasertestnet-Js
Step 3: Create a new contract
Create a new contract for Remix, which will be provided at the ZKKSync ERA Testnet. Follow the official remix documentation to create a new contract.
For example, if you want to provide a simple smart contract mycontract
with two variables, you can do this:
`JavaScript
Import {contract} from ‘@remix-starter/dapp-connector’;
Import {ZKSyncerasertestnetjs} from ‘ZKSync-Erasertestnet-js’;
Const mycontract = {
init: async (context) => {
// initialize the contract variables
context.state.myvar = ‘Hello, world!’;
return;
},
};
Const Contract = new contract (MyContract);
// provide the contract in ZKKSync era testnet
console.log (‘contract for zkkssync era testnet’);
`
Step 4: Use metamask with remix
If you have created a new smart contract and provided for ZKSync ERA Testnet, use Metamask with a remix as an injected provider. You can do this from:
- Open the remix in your web browser
- Click on “Prepare” or “Provide Treaty”
- Selecting
ZKSyncerasertestnet-Js
from the dropdown list of the providers
Metamask then injects the contract address and ABI into the provision process so that they can interact with the implemented contract.
Step 5: Test your intelligent contract
If metamask and remix are configured correctly, you can now test your smart contract on ZKKSync ERA. You can use the DAPP interface in Tools from Remix or third-party providers such as OpenSPELIN TESTRPC to interact with your smart contract.
