About

We're Payy - and we're building the future of global consumer banking built on crypto rails. Think Revolut, Venmo or CashApp - but global, fast and self custodial. Our app is written in React Native, but all the core app logic is written in Rust and compiled into Typescript. We also built Payy Network, a decentralised ZK rollup for payments. There are a lot of fun and challenging things to work on!

Payy is part of Polybase Labs. Twitter
