Extended DEX: Revolutionizing On-Chain Trading with Institutional-Grade Performance

In the rapidly evolving world of decentralized finance (DeFi), Extended is making waves as a next-generation perpetual decentralized exchange (perp DEX) built on Starknet. Developed by a team of former engineers from Revolut, Extended aims to deliver institutional-grade performance while ensuring full user custody. With its innovative approach to on-chain derivatives, the platform is poised to redefine how traders engage with both cryptocurrency and traditional financial markets.

What is Extended DEX?

Extended is not just another trading platform; it represents a significant leap forward for modern on-chain traders. By enabling leveraged perpetual trading across crypto and traditional finance (TradFi) markets, Extended allows users to utilize USDC as collateral and offers leverage of up to 100x. The platform’s unique mission combines a fintech-grade user experience with the transparency and self-custody features inherent in DeFi, quickly establishing itself as one of Starknet’s leading applications by total value locked (TVL).

The Three-Phase Vision Behind Extended

Extended’s ambitious roadmap is structured around three strategic phases aimed at evolving the exchange into a comprehensive on-chain financial network.

1. Phase One focuses on delivering a high-performance perpetuals engine with extensive market coverage.
2. Phase Two introduces unified margin logic, allowing traders to manage risk and capital across perps, spot, and lending within a single system.
3. Phase Three aims to open this unified margin framework to external protocols, enabling developers to build interoperable financial applications on Extended’s infrastructure.

This phased approach reflects the team’s commitment to reshaping the DeFi market structure and expanding beyond traditional perp DEX boundaries.

Differentiation in a Crowded Perp DEX Landscape

In a market dominated by platforms like Hyperliquid, Extended sets itself apart through its unified margin vision, support for TradFi markets, and a focus on mobile-native integrations. These features position it as a more flexible and capital-efficient alternative to conventional perp DEXs. The combination of fintech polish, Starknet scalability, and cross-asset market access gives Extended a unique competitive edge, signaling a shift toward a more integrated, user-centric derivatives infrastructure.

How Does Extended Work?

Extended operates through a hybrid architecture that combines off-chain execution with on-chain settlement, creating a fast and trustless trading environment. The core design utilizes an off-chain matching engine to process orders, evaluate risk, and sequence transactions, while all final settlements occur on Starknet. This structure ensures low-latency trading without compromising user custody or transparency.

When a user submits an order, the off-chain engine evaluates margin requirements and matches the order within its central limit order book. Once matched, the trade is finalized on Starknet, where STARK proofs validate the transaction, ensuring compliance with on-chain rules.

Extended Vaults and Security

Extended Vaults are specialized smart-contract containers designed to automate trading strategies while preserving user custody. Users can allocate capital into predefined vault strategies that operate within strict, transparent parameters, optimizing execution quality and reducing operational overhead. Each vault is isolated, ensuring that user deposits remain protected from system-wide failures.

The security model of Extended is built on self-custody, transparency, and cryptographic enforcement. All user assets are stored in Starknet smart contracts, and the system employs strict risk controls, including margin checks and liquidation safeguards, to protect user capital.

Conclusion

Extended emerges as a high-performance, self-custodial perp DEX that seamlessly blends fintech-level execution with Starknet’s scalability. Its hybrid architecture, automated vault strategies, and rigorous security framework position it as a foundational component of the evolving on-chain financial ecosystem. As the DeFi landscape continues to mature, Extended is set to play a pivotal role in shaping the future of on-chain trading.
