MEV and priority fees flow through channels that are hard to see and harder to access. Flowra brings them into the open — creating a transparent auction where validators, users, and searchers all participate on equal footing.
Today's Solana infrastructure tends to concentrate ordering power among a small number of providers. MEV flows through private channels, fee levels are hard to read, and validators have limited flexibility in how they participate.
Without a clear view of block congestion or competing fee levels, users tend to set fees defensively high. A more transparent market could help bring those costs closer to what's actually needed.
A single provider currently handles the majority of Solana validator infrastructure. This makes it difficult for validators to explore alternatives or optimize independently.
MEV opportunities are often handled through private arrangements that are difficult to observe from the outside. More openness here would benefit the ecosystem as a whole.
Solana's Gulf Stream architecture routes transactions privately to leaders by design. Most validators and searchers have limited visibility into MEV opportunities as a result.
Flowra builds an Open Orderflow Auction directly on Solana. Multiple validators share pending transactions to form an accessible stream. Searchers participate through a standard API, and the resulting competition creates better outcomes for validators, users, and the ecosystem.
Users can observe real-time fee levels across the network, making it easier to set fees at a level that's actually appropriate for current conditions.
MEV opportunities are auctioned openly, and a portion of the proceeds flows back to the users who originated the transactions — inspired by Ethereum's MEV-Share.
Validators can choose their own terms and select from multiple auction participants — giving them more options and greater control over how they engage with the ecosystem.
The orderflow stream is standardized and accessible through an open API — welcoming a wider range of searchers to participate and contribute to a healthier market.
Flowra connects pending transactions to an open stream of competing searchers, and routes the best bundles into the block — all within Solana's natural block cadence.
Validators run the Flowra client, which observes and forwards pending transactions via a Banking Stage hook.
Transactions are deduplicated and broadcast to all searchers in a standardized gRPC stream — no private access required.
Searchers detect MEV opportunities and submit tip-bearing bundles. Mini-auctions run in 200ms cycles matching Solana's block time.
The highest-tip bundles are selected with conflict-aware logic. Atomic execution ensures all transactions in a bundle succeed or none do.
Winning bundles are included first in the block. Validators maximize revenue. Users benefit from fair, transparent ordering.
When orderflow moves through an open auction, the benefits don't stay with infrastructure providers — they flow through to the people who actually secure and use the network.
When more searchers compete openly for the same orderflow, the tips they pay to validators naturally increase. Those tips feed directly into validator revenue — which is what determines staking yields for everyone who has SOL staked.
Flowra's open auction is designed to attract a broader pool of searchers, intensifying competition and passing the upside along to validators and their delegators.
Open auction competition drives tip revenue higher, benefiting validators and everyone who delegates to them.
Higher validator tip income flows through to staking APR, improving returns for passive SOL holders over time.
MEV proceeds that once disappeared into private channels are returned — partially — to the users who created them.
More transparent infrastructure attracts more participants, more searchers, and a more resilient Solana DeFi ecosystem.
Flowra is working toward a more transparent and accessible MEV ecosystem — one that works a little better for everyone involved.
