Customers Bank (CUBI) launched the new CUBIX API on 1 November 2024, replacing the legacy CBIT (Tassat-based) API. As of 20 November 2024, Paxos no longer supports CBIT transfers, and customers must migrate to the CUBIX API to avoid interruptions to their deposit and withdrawal processes. To enable fiat deposits and withdrawals via the CUBIX API, please follow the instructions below.
Customers unable to make this switch can continue to make deposits or withdrawals through wire transfers. For more details, please visit: How to Fund Your Account With a Wire Transfer.
