The good news: this is one of the more recoverable situations. The funds did arrive at the right address on the right chain — they're just below the threshold the order needed. That usually means it can be reconciled rather than written off.
How to tell this happened to you
Compare two numbers: the amount you withdrew from the exchange, and the amount that actually confirmed on-chain at the receiving address. If the on-chain amount is a little lower — often by a round fee like $1, or a fixed network-fee amount — the exchange took a withdrawal fee out of your total.
Check the exchange's withdrawal receipt too; it usually lists the fee separately. If the received amount is short of the link's total by roughly that fee, this is your case.
Is it recoverable?
Usually, yes — this is a reconciliation problem, not a lost-funds problem. The money reached the correct address on the correct chain; it's only under the required total. Depending on the provider, the shortfall can often be resolved by topping up the small difference so the order reaches its total, or by having the receiver credit the amount that did arrive.
Because the funds are in the right place, ROZO Rescue can usually help coordinate the fix rather than just explain a loss. This is very different from a wrong-chain or wrong-token case, where the funds may be unreachable.
What to check, step by step
- Find your withdrawal transaction hash and the exchange's withdrawal receipt.
- Note the amount you requested and the fee the exchange charged.
- On a block explorer, confirm the exact amount that arrived at the receiving address.
- Compare it to the payment link's required total.
- If it's short by roughly the exchange fee, save the hash, both amounts, and the fee for support — this is usually fixable.
How ROZO Rescue helps
Paste the transaction hash or payment ID into ROZO Rescue. It checks the received amount against the order total, confirms this is a shortfall rather than a wrong-destination error, and prepares a support packet to reconcile the difference. It's free and needs no login. ROZO is independent of OpenRouter and Coinbase Commerce, and because these cases are genuinely recoverable, the goal is to get the order completed.
How to avoid it next time
Exchange withdrawal fees are the reason 'send exactly $20' rarely arrives as exactly $20. ROZO Checkout sidesteps this by showing the total you need before you send and accepting any coin on any chain, so you're not manually math-ing around a fee you can't see until after. Pay through ROZO for a 1% convenience fee and the amount that needs to reach the provider is handled for you — no silent shortfall to chase down later.
