## What it is
TypeChain generates TypeScript bindings from Ethereum smart contract ABIs, giving statically typed access to contract methods and events. It is now soft-deprecated in favor of ABItype/Wagmi/Viem, with only critical fixes merged.

## Use cases
- generate typescript types for solidity contract abis
- type-safe ethereum smart contract calls in typescript
- integrate contract bindings into hardhat tests
- autocomplete for web3 contract methods in ide
- generate typed clients from truffle artifacts

## When to choose
- you maintain an existing codebase already using TypeChain bindings
- you need typed contract bindings for a toolchain not covered by Viem
- you only need critical fixes on a stable codegen pipeline

## When to avoid
- starting a new project - prefer Viem, Wagmi, or ABItype
- you want actively developed tooling with ecosystem support
- you parse ABIs directly in the TypeScript type system already

## Facets
- artifact type: library
- maturity: maintenance
- function: type-system, sdk
- domain: blockchain, developer-tools, web-development
- platform: -
- tags: ethereum, solidity, smart-contracts, abi, web3, code-generation, hardhat, truffle, deprecated, nodejs, typescript
