Sign once · settle in seconds · keep the proof

A link is a promise.A receipt is proof.

SealPay sends USDC on Arc and turns every payment into a record both sides can check on the public explorer. Testnet only — the tokens have no monetary value.

What it does today

Four things, finished. Nothing implied.

01

ERC-20 · 6 DECIMALS

One currency all the way down

USDC moves and USDC pays the fee. There is no second volatile token to acquire before a payment can go out.

02

NON-CUSTODIAL

The wallet signs, the app never holds

SealPay builds the transfer and hands it to your wallet. No private key, no custody, no account to create.

03

SHAREABLE

A request is a URL

Recipient, amount, memo and reference travel in the link. Open it and the checkout is already filled in.

04

VERIFIABLE

Every payment ends in a receipt

The transaction hash goes straight to ArcScan, so the payer and the payee check the same public record.

What this is not

READ THIS FIRST

A public-testnet MVP, not a production payment processor.

Memos and references live in the link and the local receipt. They are not written onchain.

History and saved requests are stored in this browser, capped at 200 each.

Requests are not reconciled against the chain — nothing marks one paid for you.

Browser tests run against a mock wallet and RPC. They do not prove live settlement.
