A Swap Can Reach the Wallet and Still Miss Your Account
A swap can reach the right wallet and still miss your account if its payout needs a memo. Check the network, address and tag before you send.

A memo-required payout needs both a destination address and a separate routing value to reach the right account. A swap service takes the assets you send, executes the exchange, then broadcasts the output to the address you entered. If that address belongs to a service that shares one wallet across many customers, the memo or tag tells it which account to credit.
Why does a payout need a memo?
A memo, destination tag or payment reference is an extra instruction attached to a transaction. The address points to the receiving wallet; the extra value helps the recipient identify the customer or purpose. Some networks make this field part of the transaction format, while some exchanges require it for deposits to shared wallets.
Think of the address as a building and the memo as an apartment number. The delivery can reach the building without reaching the intended person. On a blockchain, a missing or incorrect memo may leave the funds at the recipient’s wallet while its system fails to credit your account automatically. Recovery can depend on the receiving service and may take support time or involve a fee.
How does a memo-required swap work?
First, the swap interface asks for the payout asset, network and destination. You enter the receiving address and, when the recipient requires it, the memo or tag in its own field. The service then shows the deposit instructions for the asset you are swapping. After you send that deposit, the service processes the exchange and broadcasts the payout using the details you supplied.
Each piece has a separate job. The network determines where the transaction travels; the address names the destination; the memo routes the funds within the receiving service. A matching address alone does not prove that the payout instructions are complete. For example, an exchange deposit page may show a tag beside an address, while a wallet you control may not use that same account-routing step.
Before sending, check these details against the receiving service’s deposit page:
- Choose the exact network the receiving account supports.
- Copy the payout address, then compare its beginning and end with the displayed address.
- Enter the memo or destination tag in the dedicated field; do not append it to the address.
- Check whether the swap service supports that asset and network combination.
Some swap forms do not provide a memo field. If the recipient requires one and the form cannot pass it through, choose another supported destination or a wallet you control that does not need that routing value. Do not send a test amount until you know the same payout instructions will apply to the full swap.

What should you check before confirming?
Read the receiving service’s current deposit instructions for the specific asset. Similar-looking addresses can belong to different networks, and a memo requirement can vary by asset or account type. Treat the displayed address and memo as a pair. If the service says a tag is required, leave neither field blank, even if the address looks familiar.
Also check the swap preview before you confirm. Make sure the payout address, network and memo match your receiving instructions, and review the expected amount and any stated fee. Blockchain transfers are generally difficult to reverse once broadcast. A careful check before the deposit is the simplest way to avoid a payout that reaches a wallet but cannot be matched to your account.
