What is Extended?
Extended is a non-custodial perpetuals exchange built on Starknet by an ex-Revolut team. Traders deposit into a single cross-asset margin account, then go long or short on crypto and tokenized TradFi markets with up to 100x leverage, using yield-bearing tokens as collateral. Trades settle via zk proofs anchored to Ethereum, and Extended has cleared multi-billion-dollar cumulative volume.
