What is a txHash?
A txHash is the on-chain transaction identifier created when a wallet sends a payment. For Base USDC checkout, it is the public proof that a transaction exists on the Base network.
txHash Lookup for Base USDC payments
Paste a Base transaction hash to open the matching BaseScan record. Merchants use txHash Lookup to verify crypto payment proof, match order numbers, and confirm USDC checkout settlement after a buyer pays.
Why merchants need it
Payment records can show an order number, buyer wallet, amount, and txHash together. That makes disputes, refunds, balance checks, and paid-content unlocks easier to audit.
How to verify payment proof
Open the txHash on BaseScan, confirm the sender and receiver, check token transfer details, and compare the value with the merchant dashboard record.
Works with fixed price links
Fixed price payment links keep the real price on the backend. After checkout succeeds, the txHash becomes a permanent reconciliation record for the saved product price.
Base USDC transaction hash lookup workflow
Personal Wallet Payment System stores successful payment evidence with the checkout order. A buyer may see a success page, while a merchant can later open the dashboard and compare the saved txHash with the BaseScan transaction. This flow is useful for memberships, paid articles, file downloads, template purchases, and manual merchant invoices.
A transaction hash lookup page is not a private admin screen. It is a public search-friendly page that tells Google exactly what the tool does: Base transaction hash lookup, BaseScan transaction search, USDC payment proof, and crypto payment verification.
