Here are a few important points I’ve put together about Memos and tags.
New XRP and XLM addresses must first receive enough coins to meet the minimum reserve requirement before they can be activated. Transfers below the minimum will be rejected. When withdrawing from an exchange to a personal wallet, leave the Memo blank if the receiving address doesn’t require one—don’t enter one at random.
When transferring $XRP to an exchange, you generally need to enter both the address and the destination tag (Tag).
Revoke unused contract approvals promptly, and don’t leave unlimited approvals on your account.
