About Us

WalletConnect is the web3 communications protocol. Since our founding in 2018, we have empowered endless connections between wallets and apps, linking the web3 ecosystem together and fueling brand-new user experiences.

We began with a single API and are now pushing the boundaries of wallet technology to build up a suite of APIs, all with our signature agnosticism (any wallet, any app, any chain). In March 2022, we raised our $11M Series A from USV, 1kx, Coinbase and other leading investors, and are looking to grow.
