  • Submit a Pre-Integration Form: You will be asked to complete a short form to help us understand your business model, use case, and technical requirements.

  • Complete Compliance Checks: Our team will conduct standard compliance reviews, including KYB (Know Your Business) and AML (Anti-Money Laundering) checks.

  • Review and Execute the Legal Agreement: You will receive our legal agreement for review. Our legal team will work closely with yours to address any questions and ensure the contract is fully executed.

  1. Confirm your Sandbox Details. Once onboarding is complete, you will be asked to:
