Forgot the memo or destination tag on a swap
By the AltoSwap team · Reviewed and updated · Editorial policy
Short answerA deposit sent without a required memo arrives, but it cannot be matched to your swap automatically. The coins are not lost: contact support with your swap ID and the transaction hash so the deposit can be matched by hand. If the missing memo was on the payout to your own exchange account, it is that exchange's support that can credit it.
Which coins use a memo or tag
XRP, Stellar, TON, Cosmos and a few other networks let many customers share one address. The memo, also called a destination tag or comment, tells the owner of the address whose deposit it is. Bitcoin, Ethereum, Monero, Tron and Solana do not use one.
A personal wallet has its own address and needs no memo. A memo is only needed when the address belongs to an exchange or another shared wallet.
You forgot the memo on your deposit
When a swap needs a memo, the swap page shows it in its own box under the deposit address, marked as required. A deposit sent without it sits at the shared address, unassigned.
- Find the transaction hash of your deposit.
- Open the support chat, ask for a person, and give your swap ID and the hash.
- Wait for the deposit to be matched by hand. This can take from a few hours to a few days.
You forgot the memo on the payout
If you receive the swap into an account at an exchange and did not enter the memo that exchange gave you, the payout reaches the exchange but not your account. Only that exchange can credit it. Contact its support with the payout transaction hash, which is listed on your swap page.
How to avoid it
- On the swap form, fill in the memo field whenever your receiving address came with one.
- On the swap page, copy the address and the memo separately, and check both in your wallet before you send.
- If you can, receive into a wallet of your own. It needs no memo.
