Execute a previously quoted swap (pay-per-call)

Token returned from POST /api/v1/quote

Late-bound output recipient, honoured by venues that bind the recipient at execution time (Chainflip, Garden, Houdini Swap, Layerswap, Mayan, NEAR Intents, Rift, RAVN two-hop routes). Every other venue fixes the recipient when it prices the quote: supplying a DIFFERENT address here is rejected with INVALID_REQUEST rather than silently ignored, because the payout would otherwise go to the address the quote was priced for while this call reported success. Supply destinationAddress on the quote call instead, and it is honoured by every venue including same-chain ones. A known non-wallet address (a listed token's mint/contract, this swap's own tokens, the native-coin sentinel, burn addresses, Solana core programs, and — via an on-chain lookup that fails open — a Solana token account or program) is rejected with INVALID_REQUEST on either call — funds sent there are unrecoverable. An empty string means not supplied.

Late-bound refund recipient, honoured by venues that read one at execution time (Chainflip, Garden, Houdini Swap, NEAR Intents, Rift). Every other venue, Mayan, Layerswap and RAVN two-hop routes included, fixes the refund address when it prices the quote: one that differs from the refund the quote was priced with is rejected with INVALID_REQUEST rather than silently ignored. A quote priced without one refunds where it was priced (normally userAddress) at these venues, so a refundAddress here other than userAddress is rejected too, when userAddress is a valid address on the input chain (selling native Bitcoin with no quoted refund, a venue that can execute uses this one). Supply refundAddress on the quote call instead.
