Instant on-chain settlement in USDC. Full compliance screening on every transaction. Cash out to your bank whenever you want.
Explore interactive demo →On-chain settlement is final. No chargebacks. No disputes. No waiting for T+1 clearing. Your money arrives in seconds.
Convert USDC to USD and withdraw to your bank account on your schedule. Daily, weekly, or on-demand.
Automatic compliance receipts for every settlement. Tamper-proof, independently verifiable. Audit-ready from day one.
Every settlement follows the same path: compliance screening (OFAC, PEP, adverse media), on-chain execution (EIP-3009 authorization), and receipt generation. All in under 3 seconds. If screening detects a match, the transaction is held — never settled without clearance.
On-chain settlements are final by design. There is no dispute mechanism, no chargeback liability, no reversals. Once confirmed, it's done. Your revenue is your revenue.
Settle on Base, Ethereum, Polygon, Arbitrum, Optimism, Celo, Solana, and 14 more chains. Every chain gets the same compliance screening. One API, every chain.
Submit a signed authorization. We handle screening, execution, and receipting.
