USDCtoFiat Verify handles the payment-app setup the web app cannot do alone.

Some payment methods need a browser boundary. Verify lets approved USDCtoFiat and Peerlytics pages capture metadata for extension-gated setup and supported proof flows without adding a wallet, sidepanel, or stored extension account. Provider rules still control whether an account may receive a payment.

What the extension is

  • A Chrome Manifest V3 extension for approved origins including usdctofiat.xyz and peerlytics.xyz.
  • A stateless metadata bridge exposed as window.peer to the web app.
  • A setup tool for extension-gated payment methods before creating meaningful seller liquidity.
  • A narrow browser boundary for supported TEE/proof capture flows.
03

What it is not

  • Not a wallet and not a place where USDC is held.
  • Not a sidepanel, dashboard, proof history, or settings product.
  • Not a generic payment-app scraper for arbitrary websites.
  • Not required for every USDCtoFiat payment method.
04

Privacy boundary

Verify keeps capture sessions in tab-scoped memory and clears them after the provider tab closes, the metadata is returned, or the page is removed. It is designed around approved origins and does not add a saved extension account.

The extension helps the app prove or register the specific payment-app detail needed for a route. It does not publish your full payment-app history onchain, and it does not change the non-custodial contract path: your wallet still signs, and Base contracts still hold and release USDC.

Common questions

Do I need USDCtoFiat Verify for every deposit?

No. Verify is used only for extension-gated registration and supported metadata-capture flows. Most technical routes do not need extension registration, and registration never overrides the provider's account or acceptable-use rules.

Does the extension hold my USDC or private keys?

No. Your wallet signs onchain actions, and USDC sits in the Base escrow contract. Verify is a browser metadata bridge, not a wallet or custodian.

Does extension setup mean a provider permits the payment?

No. Verify can register a payout identifier, but the external provider controls permitted activity. Wise prohibits P2P crypto-sale receipts, while PayPal may require preapproval for cryptocurrency-related payments.
