Aionex is an independent development company on the Perpl Protocol. We are building a gas efficient fully decentralised exchange (DEX) for the Perpl Protocol. Perpl is a high-performance, orderbook-based perpetuals DEX launching on Monad. We are backed by top crypto-native investors and building the next evolution of on‑chain trading—one that combines CEX‑level performance with DeFi composability and transparency. Our mission is to bring the speed, efficiency, and capital depth of traditional finance on‑chain, without compromise.

- Proficiency in Rust.
