- 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

$3

- [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

``ts
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 }));
