The term "MEMO" or "TAG" is commonly used in the context of transactions, especially in networks like Ripple (XRP), Stellar (XLM), and others. These are optional fields often used to provide additional information or specific identification alongside a cryptocurrency transaction. Let's look at each of them:
When selling any cryptocurrency on the Ripple (XRP) or Stellar (XLM) network, you will need to enter a "MEMO" or "TAG" in your wallet when making the transfer. If you have trouble finding this field, contact the provider from which you're sending the funds.
If you send the transaction without completing this field, your cryptocurrencies could be lost, and we won't be able to proceed with your sale or recover your cryptocurrencies.
