Creating a Massa wallet
A Massa wallet is a file that contains a list of your keypairs.
Like other blockchains, Massa uses elliptic curve cryptography for the security of your coins (with secp256k1).
It means your secret key is your password allowing you to spend coins that were sent to your address (your address is the hash of your public key).
Here is how to create a Massa wallet.
From the command line interface
If your client is not running
Go to the client folder:
Start the interactive client and load a wallet file:
It will ask your wallet password in order to load wallet.dat. If the file does not exist, you will be asked to set a password and it will be created.
If your client is running
Now you can either generate a new keypair (and associated address):
Or, if you already have one from a previous wallet, you can add manually an existing keypair:
The list of addresses of your wallet can be accessed with:
Access public key(s) of addresse(s):
wallet_get_public_key <Address1> <Address2>
Access secret key(s) of addresse(s):
wallet_get_secret_key <Address1> <Address2>
From the graphical interface
If you don’t plan to stake or use the command-line client, you can also create a wallet on the web interface: head to the explorer, in the wallet tab.
Click Generate secret key then Add.
This generates a new random keypair from your computer randomness which stays on your side, it is never transferred on the network.
Now you can add more addresses or see the list of your addresses with their associated thread and balance.
Also, if you want to save this wallet and be able to restore it later, click Save wallet, and next time directly do Load wallet.
