We build TypeScript tooling for Ethereum, notably [wagmi](https://github.com/wagmi-dev/wagmi), [viem](https://github.com/wagmi-dev/viem), and [abitype](https://github.com/wagmi-dev/abitype). Our libraries are used by organizations like ENS, Sushi, Foundation, Shopify, and Stripe.

Gitcoin uses wagmi for this very website to allow you to connect your wallet, sign messages, submit transactions, etc.  Other developers build tools on top of our libraries as well, like RainbowKit, which is also used on this site. Our tools have quick become foundational infrastructure for folks building dApps on Ethereum.
