Filament (Filament Finance) is a hybrid on-chain perpetual / derivatives DEX built on the Sei Network. It pairs an off-chain orderbook with a Compartment-Based (COMB) liquidity pool to deliver deep liquidity even in thin markets, offering up to 30x leverage on crypto perpetuals using USDC collateral and oracle-based mark prices. Filament Pro is the flagship trading platform, and the project exposes a signature-authenticated REST + WebSocket order-book API at orderbook.filament.finance for market makers and programmatic traders. The team draws on experience from Goldman Sachs, BlackRock, Persistence, and Nethermind; the protocol's smart contracts were audited by PeckShield. Added to the API Evangelist network as a portfolio-lead stub and enriched from the provider's public documentation.
