Etherscan Integration Turns Contract ABIs Into npm Packages
Etherscan's Cards tab now surfaces GitMyABI, generating typed npm packages from any verified contract. Developers import the bindings via npm install and get viem-based TypeScript support.

Etherscan has added GitMyABI to its Cards tab, letting developers convert any verified smart contract ABI into an installable npm package with full TypeScript support. The integration goes live as the tool's beta, launched by Swiss Web3 firm AxLabs on February 7, 2025, goes into broader distribution.
The mechanic is straightforward. Developers browsing a verified contract on Etherscan click the GitMyABI card in the Cards tab. The service extracts the contract's ABI – the JSON interface that tells client code how to call contract functions and read events – and publishes it as an npm package under the @gitmyabi scope. Each contract gets a specific package, like @gitmyabi/aethusdc for a given USDC contract on Ethereum.
The TypeScript bindings use the viem type system. That means autocomplete on function names and arguments, compile-time checks for parameter types, and IDE warnings before a transaction hits the mempool. A developer who passes a string where a uint256 is expected sees the error in their editor, not in Etherscan's transaction status page.
