POST
/v1/transfer
This endpoint allows you to initiate a transfer of funds between a specific user and the partner account. The partner's balance is always involved in the transaction, acting as either the source or the destination.

Direction Logic:#

User to Partner: If sourceExternalUserId is provided, funds are moved from the user's balance to the partner treasury.
Partner to User: If destinationExternalUserId is provided, funds are moved from the partner treasury to the user's balance.

Constraints & Rules:#

Asset Support: Currently, only cryptocurrency and stablecoin transfers are supported. Internal transfers for fiat currencies (e.g., EUR) are not available at this time.
No User-to-User Transfers: Direct transfers between two different users are not supported. All movements must involve the partner account.
Requirement: The request must specify the amount, currency, and at least one of the external user IDs.
Asynchronous Processing:
Requests are accepted and scheduled for processing asynchronously. Business logic errors, such as insufficient funds or invalid parameters, are not validated at the initial request stage.
