Backing up offline wallets
If you’re like me, you’re using offline wallets to store your crypto. My hardware wallets and the backup phrases are in my house. So if anything were to happen to the physical storage (room, house), I’d lose access to all my crypto. People have come up with multiple ways on how to back up their crypto, and here’s how I do it:
Using BulldogBackup — https://bulldogbackup.eth.link
(There’s a Kovan testnet version available at https://bulldogbackup.eth.link/kovan/)
In a nutshell, BulldogBackup allows you to give access to a wallet for your ERC20 tokens. I effectively have another wallet (wallet B) in a separate physical location and I’ve given permission to wallet B to retrieve any values that are stored in my original wallet (wallet A). So if something were to happen to wallet A, I could retrieve all the coins from wallet B again — this way I can back up wallet A with a physical wallet B.
Setting up a backup is easy:
- Go to the page
and connect your wallet
2. Once you’ve connected your wallet, you can choose the address of the wallet to give access to, which tokens it can access and what the amount should be:
3. Press on the Grant Access button — a transaction pop-up should appear.
4. Once the address has been given access to your crypto, a second transaction will appear once the previous one has been completed:
This registers the backup with BulldgoBackup — there is a fee of 0.0001 ETH associated with it.
5. Now that the second transaction has finished, you can see what addresses can access your tokens:
If you want to access the tokens that have been granted to your wallet, log into BulldogBackup with the wallet that the tokens were granted to:
By clicking on “Transfer” the specified amount of tokens will be transferred to the new address:
