What Is a Memo or Destination Tag?
Memos and destination tags provide additional information used to process certain cryptocurrency transactions. They are common when a service assigns multiple users the same deposit address and uses an identifier to credit the correct account.
Networks such as XRP Ledger, Cosmos, and TON support this additional transaction information. The receiving service decides whether it is required.
