Bulk
An institutional-grade perpetual DEX on Solana that embeds its matching engine into the validator stack for sub-40ms trade finality.
Overview
Bulk is a decentralized perpetual futures exchange engineered for institutional and high-frequency trading on Solana. Instead of running as an ordinary program, Bulk forks the Jito-Agave validator client into a binary called bulk-agave, embedding its matching engine directly into validator nodes through a sidecar called Bulk-Tile. This lets orders bypass Solana's general transaction queue while assets stay in Solana custody.
The result is colocation-grade performance: roughly 20 millisecond order matching and about 40 millisecond trade finality, with gasless trading that charges only matching fees. A leaderless BULKBFT consensus, first-in-first-out matching, and cryptographic sorting keys protect against front-running and reordering. Bulk raised an 8 million dollar seed round led by 6th Man Ventures and Robot Ventures, with backing from Wintermute and Solana co-founder Anatoly Yakovenko as an angel, and is rolling out mainnet in 2026 with 30 percent of token supply reserved for the community.
Bulk is built for traders and desks that want centralized-exchange speed with on-chain verifiability, under a one-exchange, infinite-markets vision spanning crypto, real-world assets, and more. Traders connect a Solana wallet, and developers can integrate over REST and WebSocket APIs. Architecture and API references live at docs.bulk.trade.
The Problem
Solana's perpetuals scene has lagged its spot markets, partly because general-purpose blockspace cannot match the speed and fairness that institutional and high-frequency traders require. Latency, gas unpredictability, and front-running push serious flow to centralized venues.
The Solution
Key Features
Validator-Embedded Matching
A forked bulk-agave validator client runs the matching engine inside validator nodes, bypassing the general transaction queue.
Roughly 40ms Trade Finality
Orders match in about 20 milliseconds and reach finality in around 40 milliseconds.
Gasless Trading
Traders pay only matching fees, with no unpredictable network gas costs on trades.
Key Strengths
How Developers Use Bulk
Institutional and HFT Trading
Desks run latency-sensitive strategies with colocation-grade speed on a decentralized venue.
Permissionless Market Listing
The one-exchange, infinite-markets design lets anyone list new perpetual markets.
API-Driven Algo Trading
Developers build trading systems over REST and WebSocket with signed, replay-protected orders.
