About Frens

Our mission is to make transacting with anyone on the internet as frictionless as sending a message — so that we make crypto safe, simple, and social for all.

We are building WeChat on crypto rails: a global messaging super-app where transactions are as easy to send as messages. Think of it as texting with a crypto wallet that natively supports on-chain actions like token swaps, NFT mints, Polymarket bets, payments, and more.
