The following instructions will work if your registered wallet is on Metamask, Coinbase Wallet, Trust Wallet, or any wallet that you have written a seed phrase for. Read bottom next to The Solution!
This is a blessing in disguise if you don't already have your DPR on a Ledger. If you don't; then it will cost you some gas to do the following, but that is a small price to pay for long term security.
So if you don't have your DPR along with some ETH on a Ledger already, I would advise doing so.
Step 1.) Set up Ledger by installing Ethereum app under the manager tab, then deposit ETH & DPR to your wallet.
Step 2.) Once you have your Ledger set up with ETH & DPR balances; You make a fresh install Metamask wallet just for the import coming up. (You will never use this fresh new Metamask wallet because the 12 Phrase key is always saved to the extension on your browser, which means it is saved in some file on your computer)
Step 3.) Now that you have your Ledger and Metamask setup, you will need to open Metamask and click the top right circle where you change accounts and settings. From here you will click on "Connect Hardware Wallet".
Step 4.) After you have connected to a hardware wallet, you can now stake from Metamask with the original DPR/ETH address you used at sign up because it is now on a Ledger and connected through bridge on Metamask.
Success! This gives added security because you must have the hardware wallet connected and in hand to confirm or deny any and all transactions. Where as software wallets can be compromised and used from another location other than your personal computer/phone/tablet.
The Solution! You can also import your current wallet that you used for DPR Registration by setting up a Ledger and entering your seed phrase from said wallet on the Ledger itself. Now your wallet address is on the ledger (Verify by opening Ledger Live on your pc and view your imported wallet and funds). You can now delete Metamask and all data to get that original wallet seed phrase off your pc. If importing from another wallet app then be sure that the original seed phrase is not stored digitally anywhere. You are then going to install Metamask and create a fresh wallet which you will never use (explained in Step 2 above). Please read above starting at Step 3 now in order to finish successfully.
Thank you and good luck y'all,
