What is a memo?
A memo is a message included with a Stellar Lumens (XLM) transaction. This feature allows XLM users to append additional information that will be transmitted with their transaction to the global public ledger. A memo is usually used by receivers to identify transactions from senders by passing a unique reference in the memo field.
Why do I need to include a memo with my deposit to Blockchain Exchange?
On Blockchain Exchange, we use a single XLM receiving address for Stellar deposits from all users. We require users to include a memo when making a deposit so we can distinguish your XLM deposit from other users.
An XLM deposit made without a memo will result in your funds not being matched with your account. If you have forgotten to add a memo to your XLM deposit, contact Support here.
