WhatsABI
WhatsABI is a TypeScript library for extracting ABIs from Ethereum bytecode, even for unverified contracts.
What is WhatsABI?
WhatsABI, created by Google and Infura alumni Andrey Petrov, is a TypeScript library that extracts the ABI of a smart contract from its bytecode, regardless of whether it is verified or what source language was used. Developers can query events, interfaces, selectors, and use database loaders from just the Ethereum smart contract address. WhatsABI supports proxy resolution and works with Ethers.js, Viem, and other provider libraries.
