Memo and Destination Tag Explained: When You Need One and What If You Forget

A memo in crypto, also called a destination tag, is a short extra identifier you add to a crypto transfer so that a service sharing one address among many users knows which account or order the funds belong to. XRP calls it a destination tag, Stellar and Cosmos call it a memo, and TON uses a text comment. If the receiving service shows one, you must include it, or your deposit may not be credited.

This guide explains why memos exist, which coins use them, when you can skip them, what happens if you forget one, and how to double-check before you send.

Why shared addresses need a memo or destination tag

Most blockchains, such as Bitcoin, let a service create a fresh address for every customer at almost no cost. The address itself tells the service who paid.

Some networks work differently. On XRP Ledger and Stellar, each account must hold a minimum reserve balance to exist, so creating thousands of deposit addresses is expensive. On other chains, a single wallet is simply easier to operate.

Services on these networks often use one shared address for everyone.

With one address and many customers, the service needs a second piece of information to attribute each deposit. That is the memo or tag. Think of the address as a building and the memo as the apartment number: the delivery reaches the building either way, but without the apartment number, nobody knows whose it is.

TON's own developer documentation describes this pattern for invoice-based payments: each payment carries a unique identifier in the comment field so the service can match it to a specific user. The same page notes that some services give each user a unique deposit address instead, in which case no comment is needed.

What is a memo in crypto? Names by coin

The concept is the same everywhere, but the name and format change from network to network. Here are the coins that most commonly use one.

• XRP (XRP Ledger): destination tag. A number, not text. Wallets usually label it "Destination Tag" or "Tag". See our XRP coin page for the network details we support.
• XLM (Stellar): memo. Usually a text or numeric memo. Wallets label it "Memo" and sometimes let you pick the type.
• TON: comment or memo. A free-text field attached to the transfer. Some wallets call it "Comment", others "Memo". Our Toncoin coin page covers the network specifics.
• ATOM (Cosmos): memo. A text field that exchanges often use for deposit IDs.
• EOS: memo. A text field, commonly required by services that receive EOS on a shared account.

Other networks, including some that use Cosmos-style tooling, follow the same model. The general rule is simple: if the page you are depositing to shows a memo, tag, comment or "extra ID" field, treat it as mandatory. Our help article on the memo, tag and extra ID explains how these appear on BreezeSwap orders.

When you need a destination tag, and when you don't

You need a memo or destination tag when the receiving side uses a shared address. You usually do not need one when the address belongs to a single person or a single order.

You need one when

• You are depositing to a custodial platform that displays a memo or tag next to the address.
• An exchange order explicitly shows a memo field for your deposit.
• The recipient tells you the address is shared, or the address is identical for every user.

You usually don't need one when

• You are sending to your own personal wallet, such as a self-custody XRP or TON wallet. You control the whole address, so there is nothing to disambiguate.
• You are sending to a friend's personal wallet address.
• The service generated a unique address just for you and shows no memo field.

When receiving funds into a personal wallet, the sender may leave the field blank, or you can use a comment as a personal note. On TON in particular, comments are often used as payment references. Keep in mind that memo text is recorded on the public blockchain, so never put personal information in it.

One more nuance: some personal-wallet setups on XRP Ledger can be configured to require a destination tag. If a transfer is rejected with a "tag required" error, that is a signal the recipient needs one.

How memos and tags work on BreezeSwap orders

On BreezeSwap, every order gets its own deposit details from a liquidity partner. For most coins the deposit address is unique to your order, so no memo is needed. For coins that rely on shared addresses, the order page shows an additional memo or tag field below the address.

If you see that field, copy the value and paste it into your wallet's memo, tag or comment field, exactly as shown. It is the only way the partner can link your deposit to your order.

The same applies to payouts. If you receive a memo coin into a platform account that uses a shared address, enter your memo or tag in the payout details when creating the order. If you receive into your own wallet, you can usually leave it empty.

For example, when you swap TON to USDT, the order page tells you whether your TON deposit needs a comment.

What happens if you forget the memo or tag

If you forget the memo, your transfer still succeeds on-chain and the funds reach the correct address. The problem is attribution: the service receives coins it cannot match to any account or order.

What happens next depends on the recipient:

• Your wallet blocks it. Some wallets and some XRP Ledger accounts reject transfers without a required tag. Nothing is lost.
• The service credits it after manual review. Many platforms can match the deposit using your TxID, amount and timestamp, but this involves a support ticket and waiting.
• The funds cannot be attributed. In rare cases, particularly with very common amounts and no supporting details, matching may not be possible.

For a BreezeSwap order, a missing memo is handled like a wrong-network deposit. Recovery depends on the liquidity partner and usually takes 14–30 business days. In some cases there is a fee of up to $50 plus network fees, and some errors are unrecoverable.

The steps and the details support needs are listed in our guide on a wrong network or missing memo.

If you forgot the memo: what to do now

1. Do not send a second transfer with the memo to "fix" the first one. It does not attach retroactively.
2. Copy the TxID from your wallet or the network's explorer.
3. Note the amount, timestamp and the address you sent to.
4. Find your order ID or account identifier on the receiving service.
5. Contact the recipient's support with all of the above. The more precise your details, the faster the match.

How to double-check a memo before sending

A memo mistake is easy to prevent if you build a short routine into every transfer of a memo coin.

1. Look for the field on the deposit page. Scan for any label reading memo, tag, destination tag, comment or extra ID.
2. Copy, do not type. Use the copy button, then paste. Numeric tags are easy to mistype by one digit.
3. Paste into the right field. Pasting a memo into the address field, or the address into the memo field, is a common error.
4. Compare before confirming. Check the address and memo on your wallet's confirmation screen against the order page.
5. Check the network too. A correct memo does not help if the network is wrong. XRP, TON and USDT on TON all need the matching network selected.
6. Test with a small amount for large deposits. On a service that allows multiple deposits, send a small amount first and confirm it is credited.

Also watch for the reverse mistake. Some users type the memo from one platform into a transfer to another, or reuse an old memo. Always take the memo from the current deposit page.

FAQ

What is an XRP destination tag?

It is a number attached to an XRP transfer that tells a platform using a shared address which account the payment belongs to. If the recipient shows a tag, include it exactly.

Do I need a TON memo when sending to my own wallet?

Usually not. A personal TON wallet belongs to you alone, so no comment is required. You need one when a service with a shared address shows it on the deposit page.

I forgot the memo. Is my crypto lost?

Not necessarily. The funds reached the right address but cannot be matched automatically. Contact the recipient with your TxID, amount and order ID.

On BreezeSwap, recovery depends on the liquidity partner and usually takes 14–30 business days. In some cases there is a fee of up to $50 plus network fees, and some errors are unrecoverable.

Is a memo the same as a destination tag?

Yes, in purpose. Both identify the recipient behind a shared address. "Destination tag" is the XRP Ledger term; "memo" or "comment" is used on Stellar, Cosmos, EOS and TON.

Is the memo private?

No. Memos and tags are recorded on the public blockchain. Use only the identifier a service gives you and never include personal data.

Conclusion

A memo or destination tag is a small field with a big job: it tells a shared address who the payment is for. Include it whenever the deposit page shows one, skip it for your own wallet, and copy it rather than typing it. When you are ready, start a swap and check the memo field on your order page before sending.
