Even though Luxstack was shut down over five years ago, there's a chance that someone still has bitcoins stored on it. Thankfully, Luxstack was a non-custodial wallet that generated a 12-word passphrase using the BIP39 standard. Coin Wallet is compatible with this standard.
How can I retrieve my bitcoins from a Luxstack wallet?
You must create a new Coin Wallet account using your 12-word passphrase from the Luxstack wallet in order to retrieve your bitcoins from the wallet.
Then click on Bitcoin.
The "Derivation path" page should open.
In the "P2PKH - Legacy" input, type m/0' and press the "Save" button.
You can now use the bitcoins you own. If you continue to experience problems, please email email@example.com to our helpful staff.
