Fixed and floating quotes
Explain rate protection and expiry before a user creates an order.
Floating quotes
A floating quote is an estimate. In live mode the final output can change while a provider processes the exchange.
Fixed quotes
A fixed quote can be protected for the provider’s deposit window. The server checks whether the provider returned the information needed for a fixed-rate request.
Expiry and refresh
Use expiresAt to decide when a quote needs refreshing. The exchange interface refreshes estimates and clears a stale value when the pair or amount changes.
