Flash Trade V2

Developer documentation for the Flash Trade v2 API — the Flash perpetuals engine with near-instant, gasless execution. All endpoints are under the /v2 path prefix.

What's different from v1

• One account per wallet. All positions and orders live in a single per-owner Basket (one position per market) — no standalone Position/Order accounts. Identify a position with (owner, marketSymbol, side).

• Funds lifecycle. Funds move through deposit → delegate → trade → withdraw. Account & funds calls submit to your Solana RPC; trading calls submit to the v2 RPC endpoint.

• Streaming. A wallet's state streams as a basket snapshot (raw bytes + metrics) rather than separate positions/orders arrays.

See ProtocolConcepts for the full conceptual model.
