Wagmi is a collection of React Hooks containing everything you need to start working with Ethereum. Wagmi makes it simple to connect your wallet, display ENS and balance information, sign messages, interact with contracts, and much more —all with caching, request deduplication, and persistence. Developers can inject functionality with webhooks available in the Wagmi npm package. Wagmi is supported by GitHub sponsors and a Gitcoin grant.

Alchemy Notify

Alchemy Notify is a handy toolkit of APIs that register interested parties to notifications and updates when events take place on-chain. Users can set up notifications to get updates when tokens enter a known wallet address. Developers can build notifications into dApps to keep teams up to date with events happening on a blockchain.
