FAQ
Technical & compliance questions.
Which assets and networks are supported?
USDC and USDT payouts on EVM networks (Polygon, Arbitrum, Optimism, Base, BSC, Ethereum), Tron, and Solana. Exact asset availability depends on the network.
How do webhooks and idempotency work?
Webhooks are signed with HMAC so you can verify authenticity. Requests accept an idempotency key so retries never create duplicate payouts.
Is there a test environment?
Yes. Test and live modes are fully separated, each with its own scoped API keys, so you can build the full flow in the sandbox before going live.
What does onboarding (KYB) involve?
You submit your business information for Know-Your-Business review. A compliance officer reviews and approves your organization before you can send live payouts.
How are large payouts controlled?
You can configure limits with threshold-based approvals (maker-checker), so payouts above a threshold require a second authorizer.
How is compliance handled?
Every payout is screened against OFAC sanctions lists, movements are recorded in a double-entry ledger, and all activity is captured in a complete audit trail.
