Extended, formerly known as X10, is enhancing its hybrid derivatives exchange, offering open access to users following a successful invite-only launch that saw $300 million in trading volume. The platform features unified portfolio margining, allowing users to trade both spot and perpetual contracts with a single collateral pool, improving capital efficiency—a practice still uncommon in DeFi. Extended achieves ultra-low latency of 10-20ms through centralized order processing with trustless on-chain settlement, supported by StarkWare's StarkEx technology. CEO Ruslan Fakhrutdinov emphasizes a trust-minimized architecture with permissionless withdrawals, and plans for migration to Starknet. A standout feature of Extended is the segregation of user collateral into individual sub-accounts, ensuring complete transparency and legal risk mitigation, unlike other platforms that pool funds. With a focus on asynchronous, parallelized settlement, Extended aims to match the efficiency of centralized exchanges without offering its own token at this stage, instead planning to introduce a points program soon.
