Overview
Extended Exchange is a hybrid perpetuals trading platform built on Starknet that combines the performance of centralized exchanges with the non-custodial security of decentralized finance. Its primary value is delivering up to 50x leverage, sub-10ms order latency, and on-chain settlement — all without surrendering custody of user funds.
Formerly known as X10, Extended was founded by an ex-Revolut team with backgrounds from Goldman Sachs, Deutsche Bank, Bitget, and R3. The team raised $6.5M to build a crypto exchange designed to fill the institutional trust gap left by collapsed centralized platforms like FTX. Extended operates a Central Limit Order Book (CLOB) with off-chain order matching and on-chain settlement via Starknet zero-knowledge proofs, inheriting Ethereum's security layer.
Secure
All assets held in Starknet smart contracts; Extended has zero custodial access, backed by Ethereum ZK-proof validation.
Web
Accessible via app.extended.exchange and Ready Wallet mobile app on iOS and Android for seamless on-the-go trading.
