Creating a Massa wallet

A Massa wallet is a file that contains a list of your private keys.

Like other blockchains, Massa uses elliptic curve cryptography for the security of your coins (with secp256k1).

It means your private 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:

cd massa/massa-client/

Start the interactive client and load a wallet file:

cargo run

It loads the wallet file wallet.dat. If it does not exist, it is created.

If your client is running

Now you can either generate a new private key (and associated public key/address):

wallet_generate_private_key

or, add manually an existing private key if you already have one from a previous wallet:

wallet_add_private_keys <your_private_key>

The list of addresses and keys of your wallet can be accessed with:

wallet_info

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 private key then Add.

This generates a new random private key 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.
