TAGS AND MEMOS (IMPORTANT)
Some blockchain networks use additional identifiers called tags or memos.
A tag or memo is extra information included with a transaction to help identify the intended recipient when multiple users share the same wallet address.
Why exchanges require tags or memos
Centralized exchanges often use shared wallet addresses for deposits.
Because many users send funds to the same address, the exchange relies on tags or memos to determine which account a deposit belongs to. If a required tag or memo is missing or incorrect, the exchange may not automatically credit the funds.
Why personal wallets usually do not require them
Personal wallets typically use unique addresses that belong to a single user.
Because there is no shared custody or internal account system, tags or memos are usually not needed for wallet-to-wallet transfers.
Networks where tags or memos are common
Tags or memos are commonly used on certain networks, including:
- XRP Ledger
- Stellar (XLM)
- Some other payment-focused networks
Requirements depend on the receiving platform, not just the blockchain.
