Solana's perpetual contract decentralized exchange (DEX), BULK, has successfully raised $8 million in a seed funding round. The financing was led by 6th Man Ventures and Robot Ventures, with additional investments from Big Brain Holdings, Wintermute, and Solana co-founder Anatoly Yakovenko. BULK aims to address issues like high priority fees and network congestion by integrating its execution layer directly into Solana's validator stack. The DEX plans to launch a testnet in the coming weeks, with a mainnet launch anticipated in the fourth quarter.
