Why Outpay wins

Faster settlement, clearer records, less manual work.

Traditional payment flows optimize for cards. Manual wallet payments optimize for nothing. Outpay gives stablecoin checkout a real operating layer.

Seconds

Faster settlement

Customers pay in USDC on Base and funds land directly in your wallet, without multi-day card settlement delays.

Traceable

Transparent payment state

Every order is tied to amount, token, network, destination wallet, transfer match, and webhook delivery.

Automated

Lower payment ops

No screenshots, explorer checks, or spreadsheet reconciliation for every stablecoin order.

Platform surface

Everything around the payment, handled.

Outpay is more than a wallet address on a page. It gives your team the checkout, verification, events, and operational visibility required to run stablecoin payments as a provider-grade workflow.

Hosted checkout

Exact-amount payment pages with token, network, wallet, and order context locked in.

On-chain detection

Outpay watches Base and confirms only matching USDC transfers.

Signed events

Your backend receives verified payment events for fulfillment and reconciliation.

Operations dashboard

Payment status, webhook delivery, and checkout history stay visible to your team.

Settlement model

Funds move directly. Confirmation stays automated.

Customers pay your wallet directly. Outpay sits in the workflow as the checkout, detection, and webhook layer, not as a custodian of funds.
