# Get the message and decypher it

When you receive a 1-drop transaction, it might contain a hidden message for you.\
\
By checking the raw transaction data in your block explorer and looking at the memo field, you can find an encrypted message. You'll see a scrambled string of characters - this is your encrypted message. Since this message was encrypted using your public (outside) key, only your private (inside) key can decrypt it.\
\
By copying this encrypted text and using your private key, you can transform this unreadable data back into the original message that was meant for your eyes only.
