Stablecoin checkout that settles directly to your wallet.
Payclave helps merchants create hosted checkout sessions and invoices for a configured receiving asset, starting with USDT on Polygon and USDC on Base. Customers connect a supported wallet or scan/copy a one-time checkout address, and Payclave verifies settlement onchain before marking the invoice paid.


Scan/copy checkout supports deposits across 16 networks. Wallet checkout uses supported source tokens from the connected wallet while merchant settlement stays simple: USDT on Polygon or USDC on Base.
Checkout sessions, invoices, verification, and webhooks without custody.
Payclave provides the customer-facing checkout, merchant dashboard, API keys, payment records, webhook delivery, and audit trail. Funds settle to the wallet you configure, not to a Payclave balance.


Wallet or scan/copy payment. Configured stablecoin settlement.
Customers can connect a supported wallet or generate a one-time checkout address for supported networks. The receiving wallet can be configured for USDT on Polygon or USDC on Base.

Use a publishable test key with the JavaScript or React SDK, or create checkout sessions from your server with a secret key. Signed webhooks, retry logs, and idempotency keys are part of the API surface.
Customer funds never sit with Payclave.
Payclave orchestrates checkout instructions, records attempts, and verifies settlement. It does not create merchant balances, hold funds, or manage private keys.
No Payclave-held funds. Settlement goes to the receiving wallet configured by the merchant.
USDT on Polygon and USDC on Base keep receiving-wallet setup narrow, explicit, and easier to verify.
The trust-building pieces are already in the product.
These are the surfaces merchants can evaluate today: checkout creation, direct settlement, independent verification, dashboard records, SDKs, and webhook delivery.
Hosted checkout sessions
Create checkout sessions and invoices, then send customers to a Payclave-branded checkout URL.
One-time checkout addresses
The scan/copy flow creates checkout-scoped payment instructions for supported deposit networks.
Independent verification
Invoices become paid only after onchain checks confirm the transaction hash, chain, token, recipient, amount, expiry, and duplicate-use rules.
Signed webhook delivery
Payment events are signed, delivered with attempt logs, retried after endpoint failures, and replayable from the dashboard.
Merchant dashboard records
Review invoices, payment records, API keys, receiving wallet setup, webhook endpoints, and delivery state.
JavaScript and React SDKs
Use a hosted checkout redirect, a framework-free button, or a React checkout button with structured errors.
