ethers-opt

Collection of heavily optimized functions for ethers.js V6

Features

• Various functions and classes extending utility of ethers.js

• Custom fixtures / tasks for hardhat to improve scripting (for more info see ./src/hardhat/README.md)

• Inherited classes ( Provider, Signer ) to address multiple known issues of ethers.js

• Provider (JsonRpcProvider) returns FeeData from node as-is without multiplication for various usage

• FeeData optimized for BNB Chain & Polygon network, it fixes buggy behavior of what ethers.js provider does by default

• Static network by default with network validation without any additional functions, just use the class provision as-is

• Multicall provider inherited and enabled by default.

• Contract calls are aggregated to multicall if they don't specify any additional override params ( like blocktags, only the latest block call will be aggregated )

• Helpful batching class to fetch historic data ( like logs ) at the maximum speed

TO-DO

• [x] Test cases

• [x] Basenames support / Universal Resolver support for ETH ENS

• [] ENS support for alternative chains? ( Like BNB Chain for example )

• [] Optimism Deposit / Withdrawal ( aka Fault Proof )

• [] Arbitrum Deposit / Withdrawal

• [] Test EIP-7702

• [] Example blockchain indexer

• [] Port for Viem

• [] Network that checks if common contracts (Multicall, OpGasPriceOracle) exists

Quick Start

import { Provider, ProxySigner } from 'ethers-opt';

async function main() {
    const provider = new Provider('https://rpc.mevblocker.io', undefined, {
        chainId: 1,
    });

    // VoidSigner can't sign but useful to populate transaction objects btw
    const signer = ProxySigner.fromAddress((await provider.resolveName('vitalik.eth') as string), provider);

    console.log(await signer.populateTransaction({ to: signer.address, value: 0n }));
}
main();
