Ledger Hardware Wallet
Did you know you can use your Ledger Nano S hardware wallet to securely store your Mina private keys? The team are working on support for Ledger Nano X, but currently (July 2021) this is has not been completed.
The operations supported by Ledger Nano S are:
• Keypair generation
• Signing payment transactions
• Signing delegation transactions
The security audit so far has found no vulnerabilities, but until it is fully audited using is at your own risk. Make sure you have a backup of your Ledger’s BIP39 secret mnemonic phrase or use a separate Ledger device for testing this app.
Never reuse the same keypair from a testnet on mainnet!
