Flowra has launched its Open Orderflow Auction for Solana, an open block-building system that lets registered searchers compete transparently for transaction inclusion. The framework is intended to broaden participation in Solana’s MEV (maximal extractable value) market, improve price discovery and give validators a larger share of blockspace-related revenue. In testing on a single validator, Flowra said compute units per block rose 20.6%, moving from 84% to 101% of the network average, while block fees were higher than those of comparable validator software. The same setup recorded 100% block production and 99.999% block engine uptime. Flowra has also introduced Programmable Block Policy, which lets validators set transaction-inclusion rules and support regulatory or institutional compliance screening without changing the Solana protocol. The company is onboarding institutional-grade validators and said its auction is available to validators and searchers across the Solana ecosystem.
