SANDBOX - v2.2.5 - 2025-02-11

We’re pleased to introduce version 2.2.5 in the Sandbox environment, featuring robust improvements to our Payments API.

Key changes include enhanced security, improved transaction handling, and expanded blockchain integrations.


Key Enhancements

  • Automated Travel Message for Crypto Offramps
    A new feature generates a travel rule compliance message after receiving crypto in an offramp transaction.

  • Prevent Chain, Token, and Address Changes Mid-Transaction
    Users can no longer alter key transaction details once a transfer begins, reducing errors and fraud risks.

  • Updated Supported Fiat Currencies List
    Our onramp/offramp services now support an expanded list of fiat currencies.

  • Solana Infrastructure Enhancements
    Migrated Solana webhooks and RPC services for better performance and reliability.

  • Enhanced TRY Transfers
    Adjusted the data source for Turkish Lira (TRY) transfers to improve accuracy and processing speed.


Bug Fixes

  • API Key Exposure in Error Messages
    Resolved an issue where API keys were unintentionally included in error responses.

  • BigInt Error in Approval Step Function
    A hotfix was implemented to prevent transaction failures due to incorrect handling of large numbers.

  • OTP Issues
    Fixed one-time password (OTP) authentication issues affecting some users.

  • Tron Approval Overspending
    Adjusted Tron approval mechanisms to prevent unintentional over-allocation of funds.


Action Required

  • Review Fiat Currency Handling
    Check integrations for the updated list of supported fiat currencies.

  • Enhance Transaction Validations
    Adjust workflows to prevent chain, token, and address modifications mid-transaction.
