Sent the wrong amount to a crypto exchange order?
Do not automatically send the difference. Keep the original order and every transaction hash, wait for deposit detection, then follow the official order instructions. Underpayments, overpayments and split deposits can require recalculation or review.

DIAGNOSIS FIRST
Identify what actually happened
The result depends on the amount actually received, route minimum, rate type, timing and provider conditions. A second transfer does not automatically restore the original quote or guarantee that separate deposits will be combined.
SAFE NEXT ACTIONS
Work through the evidence in order
- 01Record the intended amount and the amount confirmed on-chain.
- 02Check the asset, network, deposit address and memo or tag.
- 03Wait for the tracker to process the original transaction.
- 04Do not send a correction unless the official order flow requests it.
- 05Provide every hash if multiple transactions were already broadcast.
KEEP THIS EVIDENCE
- Order amount, rate type and expiry
- Every source transaction hash
- Actual amount received at the deposit address
- Network and broadcast time for each payment
STOP BEFORE YOU DO THIS
- Do not assume two payments will be combined automatically.
- Do not create a new order for funds already sent.
- Do not assume an expired rate still applies.
SITUATION-SPECIFIC FAQ
Answers before you escalate
Open a ticketWill an underpayment always be refunded?
No universal result applies. It depends on the route, provider conditions and whether a return is technically and economically possible.
Can an overpayment receive the original rate?
The excess can require recalculation or review and is not automatically protected by the original quote.
Should I send the missing difference?
Only when the official order flow or provider support explicitly instructs it for that same order.
