  Important notice regarding sending ATOM from your Ledger Cosmos account to an exchange account

When sending ATOM from your Ledger Cosmos account to a crypto exchange, the exchange will often require that you add a memo to your deposit transaction.

Memos are used by exchanges to identify incoming deposits and credit ATOM coins to the correct account. Make sure you use the correct Memo type and enter the Memo exactly as instructed by the exchange.

Sending ATOM from a crypto exchange to your Ledger Cosmos account however does not require a memo. If your exchange insists that you must type in a memo before you can withdraw ATOM coins, it's safe to type any random number or leave the memo field blank.

You can learn more about the memo tags here.

 Do Cosmos accounts support tokens?

The Cosmos network enables the transfer of coins between its various blockchains through a method known as IBC (Inter-Blockchain Communication) transfer. However, Ledger Live does not yet support IBC transactions. This means that while coins transferred from another Cosmos chain to your Cosmos account via IBC will safely reach their destination, they will not be visible in Ledger Live.

Final steps

     Please be aware that adding a new or existing Cosmos (ATOM) account to Ledger Live might take some time.

    If you encounter extended synchronization periods during this process, rest assured that this is normal. Allow Ledger Live to synchronize for a few minutes. Once synchronization is complete, your Cosmos account will appear in the app, and you'll be able to add it to Ledger Live.
