Solana Validators Get Boost with Flowra's Open Orderflow Auction

Flowra has launched its Open Orderflow Auction for Solana validators, introducing an open block-building system that allows registered searchers to compete for transaction inclusion while giving validators greater control over blockspace and MEV revenue.

The auction lets registered searchers compete transparently for transaction inclusion on Solana blocks. Flowra's single-validator test raised compute units per block by 20.6%, with comparable block fees higher, demonstrating the potential of this new system.

Programmable Block Policy lets validators set inclusion rules and support compliance screening without protocol changes. This feature allows validators to control how blocks are constructed while retaining verifiability and auditability.

The Open Orderflow Auction is now available to validators and searchers, with Flowra continuing onboarding institutional-grade validators ahead of a broader rollout.
