Ethers V6

The ethers.js library is a comprehensive and concise library for engaging with the Ethereum Blockchain and its surrounding ecosystem.

Some of the main features are:

• Import and export JSON wallets (Geth, Parity and crowdsale)
• Import and export BIP 39 mnemonic phrases (12 word backup phrases) and HD Wallets
• Meta-classes create JavaScript objects from any contract ABI, including ABIv2 and Human-Readable ABI
  Connect to Ethereum nodes over JSON-RPC, INFURA, Etherscan, Alchemy or Metamask

The biggest difference between v5 and v6 is in the use of modern ES6 features. The major changes can been seen on:

• BigNumbers
• Contracts
• Importing
• Providers
• Signatures
• Transactions
• Utilities
• Removed Items

For more information check the Ethers v6 documentation.

Implementation Example

Package Install:

npm install ethers

Using Wallets

Tab -> Wallet.createRandom();
Tab -> new Wallet(PRIVATE_KEY);

Using Provider

Tab -> JsonRpcProvider
Tab -> Web3Provider (Injected Wallets i.e Metamask)

Full Example of Sending a Transaction

import { ethers } from 'ethers';
import {contract_abi,contract_adress} from "./contract";
import dotenv from 'dotenv'; 
dotenv.config();

const skale_provider = "https://staging-v3.skalenodes.com/v1/staging-fast-active-bellatrix";
const provider = new ethers.JsonRpcProvider(skale_provider);
const pk = process.env.PRIVATE_KEY || "";
const signer = new ethers.Wallet(pk, provider);

const contract = new ethers.Contract(contract_adress, contract_abi, signer);

async function ContractSendTx() {
    const data = await contract._mintTest.populateTransaction(signer.address);
    data.gasLimit = ethers.toBigInt(500000);
    data.gasPrice = ethers.toBigInt(100000);
    data.nonce = await provider.getTransactionCount(signer.address);

    const tx = await signer.sendTransaction(data)

    console.log(tx.hash);

}
ContractSendTx();
