Flowra Launches Open Orderflow Auction to Bring More Competition to Solana Block Building

Flowra has launched an Open Orderflow Auction for Solana, introducing a new block-building framework designed to make the network’s MEV market more competitive and potentially increase validator revenue.

The system allows registered searchers to compete for transaction inclusion through an open auction instead of relying primarily on closed orderflow channels. Flowra says the model can improve price discovery for Solana blockspace while giving validators access to a broader pool of competing bidders.

MEV, or maximal extractable value, refers to the value that can be generated from how transactions are ordered and included in blocks. Searchers compete to identify opportunities such as arbitrage, while validators ultimately control which transactions are processed.

In early testing on a single validator, Flowra said its infrastructure increased compute units per block by 20.6%, moving the validator from 84% to 101% of the Solana network average. The company also reported higher block fees than comparable validator software, 100% block production and 99.999% block engine uptime.
