Technical Architecture
Learn how Extended trading infrastructure handles self-custody, onchain risk checks, execution, settlement and the protocol migration from Starknet to Arc.
Overview of Extended Architecture
Extended uses self-custodied smart contracts and protocol-level checks around collateral movement, funding, liquidation and account health. User-defined price constraints and independent mark prices are part of the execution and risk model, while validity proofs provide verifiable state transitions.
Performance and Execution Quality
The architecture is designed for exchange-like responsiveness while preserving verifiable settlement. Matching and risk workflows are optimised for active markets, with the protocol evolving toward a dedicated high-throughput application layer for sequencing and financial state transitions.
Settlement and Network Evolution
Extended originally settled on Starknet and is transitioning settlement to Arc. The migration reflects the protocol’s focus on financial-market infrastructure, USDC settlement and future integrations while preserving users’ account data, positions and program history through the transition.
