How to Verify a Base USDC Transfer Before You Provide a Service
A payment screenshot is a claim. Releasing a service is a decision. This guide sets out a stop-and-check sequence for a company expecting a Base USDC transfer, with Skavio Payment Proof used as noncustodial payment confirmation and evidence — not as a tax invoice and not as an automatic service-release switch.
Start with the payment instruction, not the transaction hash
A transaction hash is one checkpoint, not the starting point. First establish what should have been paid. A transfer can be real on-chain and still be wrong for this service if it arrived on another network, used a different asset, went to an unexpected address, or carried the wrong amount or payment reference. If any anchor is unclear, pause the release decision.
- Confirm the expected network is Base for this payment.
- Confirm the asset is intended USDC on Base, not merely a token with a similar ticker or label.
- Confirm the recipient is the merchant address you expected, not an address supplied only by the payer in chat.
- Confirm the amount and payment reference match the agreed obligation. If a token contract address is needed, take it from a separately verified official source rather than from the payer’s message.
Read the transfer facts — and record uncertainty explicitly
Once the instruction is clear, inspect the transfer itself. Treat the transaction hash as an index into verifiable facts: network, asset identity, recipient, amount, timestamp and the status information available from the source you use. If the transfer is pending, missing, mismatched or not yet confirmed, do not mark the service as paid. A chain view or transaction hash can support evidence, but it does not by itself establish invoice settlement, bookkeeping approval or tax treatment.
- Record the transaction hash and the network it belongs to.
- Record the asset identity and the recipient address, then compare both with the trusted instruction.
- Record the amount and timestamp without inventing an exchange rate or a confirmation threshold.
- State clearly when the status is pending or uncertain; do not convert uncertainty into a paid marker.
Stop duplicate and unrelated transfers before delivery
A real transfer can still be the wrong transfer for this job. One transaction hash or payment reference should not be silently counted against multiple invoices or customers unless the business context clearly supports it. Internal owner transfers, test transactions and treasury movements are not customer payment evidence and should not be presented as commercial proof. If the transfer is real but the invoice number or payer context is wrong, keep the service on hold and route the case to a human.
- Check whether the transaction hash or payment reference has already been used in another payment record.
- Compare the payer context and payment reference with the specific obligation being fulfilled.
- Exclude internal owner, test and treasury transfers from customer payment evidence.
- If facts conflict, preserve the evidence and escalate rather than forcing a match.
Turn evidence into a human-reviewed release gate
Skavio Payment Proof is a separate noncustodial USDC payment confirmation and evidence product for companies. Use it to support a disciplined evidence trail, not to replace approval. Wallet-owner approval remains separate from automated verification, and verification does not itself constitute a tax invoice. Keep accounting and tax questions with qualified human review, and check the live Payment Proof interface for current terms and workflow details rather than assuming terms from another Skavio product.
- Retain a concise record: transaction hash, network, asset identity, recipient, amount, timestamp, status and duplicate-check outcome.
- Separate automated verification from the human decision to provide the service.
- Do not treat Payment Proof as escrow, custody, a bookkeeping system or a substitute for a tax invoice.
- Route accounting, tax and reconciliation questions to the appropriate human review process.
