How can I import or sweep my private keys into Atomic Wallet?

We don’t offer the option of importing or sweeping your existing private keys into Atomic Wallet. 

However, the process of sweeping constitutes nothing but creating a transaction that simply transfers all the funds from the source address to the target one. Just the same can be done by creating a new wallet in our app and manually transferring all of your funds to your newly generated addresses. 

We do plan to implement key import feature in the future. Stay tuned for that.
