Crypto Withdrawal

This module enables Partners to transfer digital assets from their balance to any external blockchain address.

Key Principles#

Network Fees: Blockchain fees are dynamic. You must check the current fee before initiating a withdrawal to ensure your balance is sufficient.
Network Accuracy: Assets must be sent via their supported networks (e.g., Ethereum/Polygon).
Compliance (Travel Rule): Every withdrawal requires recipient information (name, wallet type, receiver type) to comply with AML regulations.

Core Endpoints#

Get Network Fee
Retrieve real-time gas fee estimates. Essential for accurate balance calculation.
Create Crypto Withdrawal
Initiate an asynchronous transfer to any external address with required Travel Rule data.
Get Withdrawal Details
Track the transaction status and retrieve the blockchain Transaction Hash (txId).
CAUTION
Network Selection is Final. Sending cryptocurrency to an incompatible network or an incorrect address will result in the permanent loss of funds. We cannot reverse or recover these transactions.

Integration Workflow#

1.
Estimate Cost: Call Get Network Fee for your chosen currency and network. This is crucial because the fee is deducted in addition to the withdrawal amount.
2.
Verify Balance: Ensure your Partner Master Wallet has enough funds to cover: Withdrawal Amount + Network Fee.
3.
Execute: Call Create Crypto Withdrawal. Provide the destination address and the mandatory compliance data (name, walletType, receiverType).
4.
Monitor:
Webhooks: Recommended for receiving the transactionHash and final status automatically.
Polling: Use Get Crypto Withdrawal Details to check the progress and confirmations.

Important Notes#

Asynchronous Processing: Withdrawals are queued and undergo risk checks before being broadcast to the blockchain.
Travel Rule: For institutional or large transfers, providing accurate recipient data is mandatory for successful processing.
TxID Availability: The blockchain hash is generated and visible in the details/webhook only after the transaction is successfully broadcast (SENT status).
