# How to use wallet
The wallet is used to manage and save the private key, which is stored in the local database after encryption. Before using the wallet, you need to set the password of the wallet. A wallet has only one password, and all the private keys are encrypted with the same password. No password will only affect the functions related to the wallet (such as signature). Other functions can be used normally. The encrypted private key needs to be decrypted before use, so the unlock command is provided to realize this function. Every time the program is restarted and the wallet is used, the wallet must be unlocked.
There are two types of wallet addresses, secp256k1 and BLS. The address of secp256k1 starts with f1 and the address of BLS starts with f3. In the program, it is distinguished by the SigType field in the structure keyinfo (opens new window).
Wallet provides functions such as creating private key, importing and exporting private key, unlocking and locking wallet, viewing and setting default wallet address.
