The Locker

The Locker is a Web3 application that allows you to protect and backup any of your mnemonic seed passphrases (or any other secret text) directly on the blockchain confidentially and recover it whenever you need.

The idea is to able to recover your passphrases using a simple email. However, email alone is not very secured. So we added a social recovery mechanism that require you to have one or several people you trust to unlock your passphrases when you need to recover them.

To backup your mnemonic passphrase, you will need a single-use Keplr wallet, an email address and the wallet addresses of people you trust to hold the lock to your passphrase.

When you need top recover your passphrase, you will need yet another single-use Keplr wallet and ask your friends to transfer the lock back to your new wallet before recovering your passphrase with your email.

The mnemonic phrase is stored securely on the Secret Network, a privacy-preserving blockchain that encrypts input, output, and state of smart contracts in a way that it hides data even from the nodes on the network.
