Introduction

Binance Chain CLI has a sub-command named keys to manage private keys.
It is a key store to manage keys for users.

You can add a new key or import a key from seed.
Then you can list the keys added and show the detailed info of a specific key.
You can also delete the given key or update the password used to protect private key.

Binance Chain CLI use the keys you add to sign transactions for you.
For example, if you want to transfer tokens to someone else, you just need to specify the name of the key you want to use, and input the password of the key, then Binance Chain CLI will sign the transaction for you if the password is right.
