What happens if I send the wrong amount to a swap deposit address

05 September 2026

The exchanger will process the swap with the amount it actually received, not the amount you intended to send. If the amount is too small to meet the minimum, the swap will fail and the funds will be sent back to your sending address, minus any network fees.

Here is how the system handles the most common scenarios when the deposit amount does not match what you entered on the swap order page.

You sent less than the minimum. Every swap order has a minimum deposit amount. This is not the same as the amount you entered; it is a lower boundary set by the exchanger to cover its own costs. If your deposit is below that minimum, the exchanger will not process the order. After a timeout period (typically 30 - 60 minutes), it will return the funds to the sending address. The return transaction will deduct the blockchain network fee. No part of that fee is refunded by the exchanger. You will get back the deposit minus the network cost of the return.

You sent more than the quoted amount. The exchanger will accept the higher amount and swap it at the same exchange rate that was locked when you created the order. You will receive the larger output. This is not a bonus; it simply means the system converts what you sent. The rate does not change because you overpaid. If you sent substantially more, the exchanger may flag the order for manual review, which delays the swap by hours. Automated systems sometimes cap the overpayment at a fixed percentage (often 10 - 20 percent) above the quoted amount and reject anything beyond that threshold, returning the excess via a separate transaction. The return cost is again the blockchain fee.

You sent less than the quoted amount but still above the minimum. The exchanger will process the swap with the amount it received. The output will be proportionally smaller. The locked rate still applies, so the output is the amount received multiplied by that rate, minus any fixed fees. You do not get a partial refund or a chance to top up the order. Once the deposit is detected, the system proceeds with whatever is there.

You sent a different token or asset. If the deposit address belongs to SOL but you send an SPL token to it, the token is not recognized by the swap system. The token may be recoverable, but not through the automatic swap flow. You will need to contact the exchanger support team with the deposit transaction ID. Recovery can take days and often incurs a manual processing fee. In many cases, the token is simply lost if the exchanger cannot or will not retrieve it. Do not test this.

Why the system works this way. Swaps between chains are not reversible like bank transfers. The exchanger locks in a rate based on a specific amount at the time of order creation. Liquidity providers and internal settlement systems depend on predictable inputs. Allowing partial fills, top-ups, or automatic refunds for small discrepancies would introduce latency and pricing risk. The design is therefore rigid: send what you said you would send, within a narrow tolerance. The tolerance is usually defined in the order terms on the confirmation page.

If you discover the error immediately after sending, there is no way to cancel the order. Blockchain transactions are final. The only recovery path is the automatic timeout and return, or a manual support ticket for token mismatches.

Before you send. Double-check the deposit address and the amount field on the order page. The quoted amount is what the system expects. Sending exactly that amount avoids every issue above. If the minimum is too close for comfort, increase the send amount to stay clearly above it, but do not exceed the maximum the system allows without review.

The hub page under which this topic sits is Swapping Solana tokens without a DEX. If you have not yet read that page, it covers the broader flow of moving SOL and Solana-based assets across chains using an exchanger rather than an on-chain DEX. Understanding that flow first reduces the chance of deposit errors.
