ABI Data — grab your smart contract’s ABI as JSON from Etherscan, Polygonscan, Arbiscan, BaseScan, BscScan, FTMScan, Snowtrace, GnosisScan
Fetch smart contract ABI JSON to use with wagmi and ethers.js in your app. Records are cached for 365 days, so after the initial request for a contract, the API will respond very quickly from the CDN. This is just a simple wrapper around various *scan APIs.
