DEX Filament, an oracle-based perpetual contract, announced the completion of a $1.10 million seed round led by Lingfeng Innovation Fund, with participation from Halo Capital and Spyre Group. Other major participants include angel investors from well-known Web3 projects such as Polygon, Router Protocol, Stakecito, Chorus One, Archerman Capital, and CoinBureau, as well as former core contributors to Binance, Sei, and Tendermint. Filament was developed by teams who have worked at Goldman Sachs, BlackRock, Persistence, Nethermind, and Open Status, and is based on the Sei network. The platform introduces a new hybrid model that combines compartment-based liquidity pools with order books, enabling them to operate efficiently in low-liquidity conditions.
