Payment verification without the payment processor.
Works like Stripe Payment Intents, but for on-chain USDC.
Non-custodial. Flat-rate. Three API calls.
The payment verification dilemma
Pay 1% per transaction.
$100 fee on a $10,000 payment. Custodial. Vendor lock-in.
Parse Transfer events, handle reorgs, track confirmations.
Weeks of blockchain infra work. Ongoing maintenance burden.
