app.fortiblox.com/api/tx/build
Build an unsigned, simulated X1 swap transaction (base64 v0) for the given payer through the on-chain FortiBlox Router — routed, impact-capped, simulated before return; the 25 bps protocol fee is enforced in-program. Sign it with the payer key and broadcast via POST /api/tx/send (free). Amounts are raw base units. Requires a prior quote.
