Withdrawal Integrations

After the withdrawal transaction, the create_tx service is called. Then, information about this transaction is sent to the Defy interface. After reviewing this transaction, it is accepted or rejected. If rejected, the transaction ends here. If accepted, we handle all communication with the exchange to which the money was sent.

After all the transactions in between are completed, we specify that you start the on-chain transactions via the webhook you sent to us. You also send the transaction hash information with the send_tx service. We also send this information to the other exchange. Thus, the travel rule actions where the money is sent are completed.
