Does Atomic Wallet support NEO migration?

Yes. Atomic Wallet does support the NEO N3 network upgrade, and you can use your wallet for your new NEO.

Note: You'll need to have 1 GAS on your balance to manually migrate your NEO & GAS.

GAS is a token you use to make transactions on the NEO blockchain. By migrating, you're making a transaction that transfers your coins from your old NEO Legacy address to your new NEO N3 address. Therefore, the NEO blockchain will charge you a network fee of 1 GAS for this transaction.

Where do I get GAS? You will constantly be earning GAS by holding your NEO. Go to the Staking tab and select NEO to see how much GAS you can claim. To see your claimed GAS balance, go to the Wallet tab and search for GAS. Alternatively, you can buy GAS on any exchange where it's available.
