Best Practices

Prepare Accounts Early: Add and verify your bank accounts and wallets during your company onboarding process, before you need to create ramp requests.
Multiple Accounts: You can add multiple bank accounts and wallets to support different currencies and use cases.
Security: Never share private keys or seed phrases. Fundflow only needs your wallet address for verification.
