21 pool types, priced with each venue's own math. Geyser or plain RPC. Sub-millisecond quotes. Live /swap-stream WebSocket broadcasting every confirmed DEX swap with native + USD prices. On-chain fee enforcement with an immutable router program.
Pool state, vault balances and tick arrays via Yellowstone gRPC, or from blocks over plain RPC. No RPC on the quote path.
1 to 5 hops in one instruction, one slippage check on the final output.
Every swap settles through the open-source flow-router program: sequential DEX CPIs, a route-level minimum, an optional output-token fee. First generation audited by SigIntZero.
Dual-channel Geyser discovery — account stream + block stream. SQLite persistence for instant restart.
WS /swap-stream broadcasts every confirmed DEX swap with native + USD prices. Filter by DEX, mint, pool, or trade size. About 110 swaps per slot on mainnet.
Tick walks, bonding curves, vault shares, fee tiers: quotes match the program's output to the atom.
Server and router are MIT-licensed Rust: flow-trades-solana and flow-router-solana. Build them yourself with cargo build --release.
Read the API docs, point the server at an RPC (and optionally a Geyser endpoint), and start serving quotes in minutes.
