I have most of my Bitcoin holdings secured with a Ledger Nano X. I used the latest version of the Electrum wallet to sign the transactions. I used the Brave browser and the MetaMask extension to claim the free Hex.
Note: There is a mandatory 350 day staking period when claiming the free Hex for Bitcoin holders. I was not aware of this requirement until I tested the process for real.
I do not advise putting any ETH into the Hex project. I suggest just sticking with the freeclaim. That way you cannot lose any money.
Here is the process I went through:
- Plugged my Ledger device into my computer via USB and entered my PIN
- Opened the Bitcoin app on my Ledger device
- Opened up the Electrum app on my laptop
- Selected to use a hardware wallet and selected my Ledger device
- View menu > Show addresses
- Sort addresses by Balance, highest first
- Opened up the Brave browser on my laptop
- Unlocked my MetaMask browser extension
- Navigated to https://go.hex.win/
- Click the notice to connect MetaMask to the Hex website
- Clicked the Claim tab on the HEX website
- Right clicked and copied the first Bitcoin address from Electrum, pasted it into the HEX website
- Copied the message text provided by the HEX website
- Right clicked on the address I just used in Electrum and selected sign/verify message
- Paste the message given by the HEX website into the message box
- Click the sign button ONCE and wait
- Authorised the signing on my Ledger device
- Copy and paste the signature that is generated by Electrum and past it into the Hex website (into the signature box)
- Click submit claim
- Confirmed the Ethereum transaction when the MetaMask window popped up
- Wait for the transaction to confirm on the Ethereum network (15 seconds)
- Done
- Repeat this process from step 12 with each Bitcoin address that had a balance on the 2nd of December when the snapshot was taken
