Bulk

Bulk is a Solana perps DEX that runs as a sidecar inside the validator stack itself, with sub-40ms finality and a CLOB-style matching layer. The team raised $8M seed in 2025 from 6th Man Ventures, Robot Ventures, Wintermute, and Anatoly Yakovenko, and rebates 12.5% of taker fees back to validators running its Bulk-agave client.
