Litecoin Address Format
A Litecoin wallet is as simple as a single pairing of a Litecoin address with its corresponding Litecoin private key. Such a wallet has been generated for you in your web browser and is displayed above. To safeguard this wallet you must print or otherwise record the Litecoin address and private key. It is important to make a backup copy of the private key and store it in a safe location.
In Litecoin, to avoid confusion with Bitcoin, all 3-addresses have corresponding M-addresses, which is the preferred format. This means that whether you send LTC to the M- version or 3- version of the address, it is the same key accessing the funds. We use M-addresses to minimise risk of deposit error.
