Sandbox vs Production

The sandbox environment is designed to simulate production behavior while providing a safe testing environment:

​
Automated Compliance Approval

In sandbox, the compliance process is streamlined for testing:
  • Auto-Approved - Compliance submissions are usually approved within minutes
  • Dummy Data - Use mock data as inputs to simulate the flow
  • Magic Value - Use magic values to trigger different behaviors for testing
In production, KYC/B applications undergo real compliance review

​
Simulated Transactions

All money movement in sandbox is simulated:
  • Virtual Account Deposits - Use the simulate deposit endpoint to mimic bank deposits
  • Testnet Token - Transactions use testnet tokens and are processed on a testnet network
  • Testnet Wallets - All wallet addresses are on blockchain testnets
Only send testnet assets to testnet wallets. Real-world funds sent to testnet wallets cannot be recovered, and HIFI is not responsible for any resulting loss.

​
Transitioning to production

When you’re ready to move from sandbox to production:
  1. Generate production API keys in the dashboard
  2. Update your base URL from sandbox.hifi.com to production.hifi.com
  3. Update API keys in your environment variables
  4. Remove simulation calls - Delete any simulate-deposit endpoint usage
  5. Enable real KYC - Provide real user information and documents
  6. Test thoroughly - Start with small transactions before scaling
