Private key
The secret number that proves a wallet is yours.
A private key is used to sign transactions. Signing is how you prove that you approve a payment, without showing the key itself. The seed phrase is a way to rebuild your private keys.
Why it matters
If a private key leaks, move your funds to a new wallet right away. Treat it like the key to a safe.
