Flint

Flint (Flint Labs) is building fully on-chain market infrastructure on Solana. Its first live product, Flint Spot, is a multi-maker prop AMM for USDC-quoted spot: market makers plug in their own quoting and risk logic, Flint handles transaction submission, fees and matching, and fills from Solana aggregators settle on-chain. A fully on-chain perpetuals DEX is in development, with borrow/lend also on the roadmap. The team is backed by Ergonia, a crypto-native market-making firm with deep Solana trading experience, and is hiring remote engineers, quants and a marketing lead.
