- Flowra launches its Open Orderflow Auction to introduce competitive bidding for Solana transaction inclusion.
- The new Programmable Block Policy gives validators more control over transaction inclusion and compliance requirements.
Solana’s ecosystem is undergoing a major infrastructure shakeup. Flowra, a blockchain infrastructure company has launched a new block-building system for Solana called the Open Orderflow Auction (OOA), which is designed to create more competition around transaction ordering and give validators a larger share of the value generated by MEV.
Right now, a huge portion of Solana’s transaction ordering and MEV (Maximal Extractable Value) market remains tightly concentrated. Traditionally, many validators rely on closed orderflow channels.
Flowra’s new open auction system changes that by allowing registered searchers to compete for transaction inclusion through an open auction instead of relying on private orderflow channels. Flowra says this approach could improve price discovery while giving validators more opportunities to earn from the demand for Solana blockspace.
Early testing showed promising results. On one validator, a Flowra-enabled setup increased compute units per block by 20.6%, taking the validator from 84% to 101% of the network average. The company also reported higher block fees than comparable validator software, along with full block production and 99.999% block engine uptime during the test.
Flowra Adds Validator Controls and Compliance Screening
Alongside the auction, Flowra has introduced Programmable Block Policy, giving validators more control over which transactions are included in their blocks. This could be useful for validators that need to follow specific regulatory or institutional requirements without making changes to the Solana protocol itself.
Flowra has also announced a collaboration with compliance infrastructure provider Honeypot to bring sanctions and risk screening to this block-building layer.
The company said its approach draws from Ethereum’s competitive block-building market, where open bidding has helped increase proposer revenue. Flowra believes Solana’s high transaction throughput and low latency could support a similar model.
Flowra is currently onboarding institutional-grade validators to the Open Orderflow Auction, with a wider rollout expected as participation grows. The system is now available to validators and searchers operating within the Solana ecosystem.
