wagmi
React Hooks for Ethereum
wagmi is a collection of React Hooks containing everything you need to start working with Ethereum. wagmi makes it easy to "Connect Wallet," display ENS and balance information, sign messages, interact with contracts, and much more, all with caching, request deduplication, and persistence. We create a wagmi Client and pass it to the WagmiConfig React Context. The client is set up to use the ethers Default Provider and automatically connect to previously connected wallets. Next, we use the useConnect hook to connect an injected wallet (e.g. MetaMask) to the app. Finally, we show the connected account's address with useAccount and allow them to disconnect with useDisconnect. First, configure your desired chains to be used by wagmi, and the providers you want to use. -

TypeChain
TypeScript bindings for Ethereum smart contracts
TypeChain generates only TypeScript typings (d.ts) files, if you're looking for "opinionated", "batteries included" solution check out our new project: eth-sdk. It generates typesafe, ready to use ethers.js wrappers and uses etherscan/sourcify to automatically get ABIs based only on smart contract addresses. Under the hood, eth-sdk relies on TypeChain. Interacting with blockchain in Javascript is a pain. Developers need to remember not only a name of a given smart contract method or event but also it's full signature. This wastes time and might introduce bugs that will be triggered only in runtime. TypeChain solves these problems (as long as you use TypeScript). TypeChain is a code generator - provide ABI file and name of your blockchain access library (ethers/truffle/web3.js) and you will get TypeScript typings compatible with a given library. -
