📎 Wallet & Security | Memos and Tags
· What it is: For ease of management, many exchanges let multiple users share the same deposit address, then use a Memo or Tag to identify who each deposit belongs to.
· Why: Using a shared address with a Memo lets exchanges avoid managing a large number of addresses. The trade-off is that the Memo is the only way to tell who a deposit belongs to.
· Note: If the deposit page shows a Memo or Tag, be sure to copy both the address and the Memo / Tag correctly.
