Submit an offramp transaction

This endpoint initiates an offramp transaction, allowing users to convert cryptocurrency into fiat and transfer the funds to a designated bank account.

The exchange operation is triggered automatically upon confirmation of the crypto payment. Once received, the system releases the corresponding fiat amount to the account provided by the user during the creation of the fiatAccount.

Fiat withdrawals can be directed to third-party accounts or accounts owned by the customer.
