CloudswapMemos and destination tags
Some coins need an extra code to reach the right account. Here is when it matters and when you can skip it.
What a memo is
Coins such as XRP, TON, Stellar and EOS can use a memo, also called a tag or a comment. Exchanges and custodial wallets often give all their users one shared address and tell them apart by this extra code.
When you need one
If you receive coins to an account on an exchange or another custodial service, it will show you both an address and a memo. Enter both in the swap form, otherwise the coins arrive at the right address but cannot be matched to your account.
If you receive to your own wallet, you usually do not need a memo. Leave the field empty unless your wallet asks for one.
When you send a coin that uses a memo
If the swap page shows a memo next to the deposit address, include it in your transfer exactly as shown. A deposit without it may not be credited to your swap.
