Extended

Extended is a digital trading platform designed to bring crypto and traditional finance markets into one account. Its unified margin system lets users trade across markets and use multiple assets as collateral, rather than managing separate margin arrangements. The platform also offers yield-generating collateral and trading with leverage of up to 100x.

Extended says its product is powered by a system with open-source smart contracts, full self-custody, and verifiable execution. Its underlying infrastructure uses Starknet, a general-purpose zk-chain secured by Ethereum, where state transitions are verified to support transparent and trustless execution. Extended describes its chain as a work in progress and presents the platform as comprising the Extended interface, its underlying chain, and tools for external builders.

The company provides documentation and developer resources, including an API and SDK, alongside platform statistics and builder resources. Users can access the trading app and connect with the community through X, Discord, and Telegram.
