Flowra launched its Open Orderflow Auction on 21 August 2026, a block-building framework that lets registered searchers bid openly for Solana transaction inclusion instead of routing through closed orderflow channels. The Seoul-based company also introduced Programmable Block Policy, which lets validators define their own transaction inclusion rules at the block-building layer without changes to the Solana protocol, with sanctions and risk screening supplied through a collaboration with Honeypot. In early testing on a single validator, a Flowra-enabled setup raised compute units per block by 20.6%, moving that node from 84% to 101% of the network average, with 100% block production and 99.999% block engine uptime.
