Memo Fields Explained: The Deposit Detail That Strands XRP and TON Transfers

Bitcoin deposits need one piece of information: an address. XRP and TON transfers to a casino or exchange often need two: the address and a short memo that tells the receiver whose payment it is. Leave the memo out, and the coins still reach the right wallet. The platform cannot match them to your account, though, so the balance stays frozen until support traces it by hand. Each network names and formats the field differently, and wallet apps rename it again. Learn the label in each place and a deposit moves without a hitch.
