Before swapping, check whether the receiving address needs a memo or destination tag, and include it with the payout if it does. The address identifies the destination, while the memo can identify your account there. A correct address with a missing memo may send funds to the exchange without crediting your balance.
What does a destination memo do?
A memo or destination tag is a short extra value attached to some blockchain payments. Exchanges may use one shared address for many customers, then use the memo to tell deposits apart. The address and memo work together like a building address and apartment number.
The required field depends on the asset and the receiving service. For example, an XRP deposit may use a numeric destination tag, while a Stellar payment may use a memo. A wallet you control may use a unique address and ask for no memo. Follow the receiving service’s instructions for that exact asset and network.
How do I include it in a cross-chain payout?
Check the destination details before you start the swap. If you’re sending to an exchange, open its deposit instructions for the asset you expect to receive. Copy the address and any required memo or tag, and confirm the network matches the payout.
For example, say you’re swapping BTC for XLM and want the XLM credited to an exchange account. The exchange gives you an XLM address and a memo. You need the swap’s payout to send both details; putting the memo in a note or keeping it only in your records won’t attach it to the blockchain payment.
Cross-chain swaps add a step: the source asset is sent on one network, then the received asset is paid out on another. With Chainflip, that general process uses native assets across chains rather than wrapped copies. When comparing swap services, check that the destination payout can carry any memo your recipient requires; Chainflip crypto is one example of a service for native cross-chain swaps.
If the destination form has no memo field, don’t guess that the memo is optional. Confirm whether that payout route supports the needed field before sending. If it does not, use a destination address that does not need one, or choose another route that can include it.
What if the memo is missing or wrong?
The transaction may still reach the receiving address, but the exchange may not know which account to credit. The funds can be delayed or require the exchange’s recovery process; recovery is not guaranteed. A blockchain confirmation alone does not prove the exchange credited your account.
Before confirming, check the address, network, and memo against the receiving service’s current deposit details. If you’re unsure, try a small amount first where practical, then verify it appears in the destination account before sending more.
For an exchange payout, treat the memo as part of the destination address whenever the exchange requires it.
