*Important* After importing into Edge, we highly recommend this additional step to maximize the security of your assets by moving them to new & never before exposed private keys.
Tap Menu (upper right) > Settings > Migrate Wallets, and select any imported wallets you wish to secure. This procedure sweeps all the funds from your imported key, into brand new wallets, where each wallet will has its own, unique private key that has never been exposed before in anyway.
Once you tap Next and confirm, your funds will be sent, on-chain, into newly created wallets within your Edge account. Please note, this action will incur blockchain fees. Edge is free to use and these transaction fees are paid purely to the miners and stakers who secure each blockchain.
