# Crypto Quote Expiry: What Happens When the Timer Runs Out?

> A quote expiry limits how long a particular token amount and payment window remain valid. It helps a gateway match the transfer and manage changing prices. An expired timer does not by itself tell you whether a transaction was sent, mined or received correctly.

Understand why token quotes expire and how to handle a transfer near the deadline without creating duplicate payments.

## Separate the invoice from its token quote

A USD-priced invoice can produce a cryptocurrency quote when the buyer chooses an asset and network. That quote has a recipient, exact integer quantity and time window. Copying its amount into a wallet and returning much later can create a mismatch even if the original invoice still exists.

For example, a customer might open an ETH checkout, pause for lunch and then use the earlier amount. The safer path is to return to current checkout instructions before sending. A fresh quote can differ because the market price or matching precision changed.


## Distinguish broadcast time from chain evidence

A wallet can report submission before a transaction is included. Coinvay’s transfer verification checks blockchain timing against the quote window. A customer pressing Send just before the countdown ends is not a guarantee that every later mined transaction will satisfy the quoted conditions.

Confirmation accumulation is another stage. A transfer mined within the permitted window can finish accumulating the required confirmations afterward. Coinvay’s separate sandbox supports checking such a timely mined transfer by hash after its test checkout expires. That is different from reopening the expired request to accept any new transfer.


## Resolve uncertainty before another attempt

When a payment is near expiry, preserve its transaction reference and inspect the receiving state before asking the customer to resend. A second payment can duplicate a first transfer that was merely slow to become visible.

For a new unpaid attempt, obtain fresh instructions instead of manually extending an old number in a support message. If an actual receipt falls outside the supported window, use an accurate exception-handling process. Do not label it confirmed against a quote it did not satisfy.


## Practical checklist

- Read the current quote immediately before approving the transfer.
- Preserve the hash when a payment is submitted near expiry.
- Check the first attempt before creating or sending a replacement.

## Questions and answers

### Does quote expiry remove a transfer from the blockchain?

No. A transfer that was actually broadcast or mined has its own network lifecycle. The expiry controls payment-request acceptance and matching, not the existence of chain history.

### Can I always reuse an expired amount?

No. A later transfer may fail timing or exact-quote checks. Request current instructions for a new payment and investigate existing attempts separately.
