Ethers.js

Overview​

Ethers.js is a compact library designed to enable developers to interact with the Ethereum blockchain. By using Ethers.js, you can interact with smart contracts deployed on Soneium Minato.

Install​

To install Ethers.js, run the following command:

$ pnpm i ethers

Setting Up the Provider and Connecting to Minato​

To begin using ethers.js, set up your provider as shown below:

import { ethers } from 'ethers';

const rpc = 'https://rpc.minato.soneium.org/'
// Connect to the Soneium Minato RPC
const provider = new ethers.JsonRpcProvider(rpc);

Reading Data from Soneium Minato​

You can read data from Soneium Minato by using the provider. For instance, to get the balance of a specific wallet address, you can use the getBalance method:

import { ethers } from 'ethers';
import { provider } from './config'

const address = '0xYourWalletAddress';
const balance = await provider.getBalance(address);
console.log(`Balance: ${ethers.formatEther(balance)} ETH`);

Writing Data to Soneium Minato​

To send transactions or interact with accounts, you need to create a signer using your private key. This allows you to sign and send transactions:

import { ethers } from 'ethers';
import { PRIVATE_KEY, provider } from './config';

const signer = new ethers.Wallet(PRIVATE_KEY, provider);

const tx = {
  to: '0xDestinationAddress',
  value: ethers.parseEther('0.01'),
  gasLimit: 21000,
  gasPrice: ethers.parseUnits('20', 'gwei'),
};

// Send the transaction
const transaction = await signer.sendTransaction(tx);

Interacting with Smart Contracts​

Ethers.js provides a simple interface to interact with Ethereum smart contracts. Below is an example of interacting with an ERC20 contract on Soneium Minato.

Read the values from the contract:

import { ethers } from 'ethers';
import { erc20Abi } from './ABI';
import { USDC_ADDRESS, SENDER_ADDRESS, SPENDER_ADDRESS } from './config';

const contract = new ethers.Contract(USDC_ADDRESS, erc20Abi, provider);
const allowance = await contract.allowance(SENDER_ADDRESS, SPENDER_ADDRESS);

Send contract function:

import { ethers } from 'ethers';
import { erc20Abi } from './ABI';
import { PRIVATE_KEY, USDC_ADDRESS, SENDER_ADDRESS, SPENDER_ADDRESS, provider } from './config';

const signer = new ethers.Wallet(PRIVATE_KEY, provider);
const contract = new ethers.Contract(USDC_ADDRESS, erc20Abi, signer);
const amount = "1000000";
await contract.approve(SPENDER_ADDRESS, amount);
