# Node Wallet

Every node has a connected wallet providing:

  • ability to mine.
  • ability to sign transactions.

A node can have a single wallet with a single seed, contained in the wallet.

In this article, the following use cases of wallet are reviewed:

# Creating a New Wallet From Scratch

On startup a node creates wallet if the directory listed in wallet section of node's configuration file does not already contain wallet.dat file.

During the wallet creation the node will:

  • generate random seed;
  • write the generated seed to STDOUT;
  • request in the console password to encrypt seed.

The seed phrase written to STDOUT should be stored in a safe location. The seed phrase can not be restored. You can only restore the hash of the seed phrase: you can get it with GET /addresses/seed/{address} Node REST API method. You can then use the hash to get the accout private key.

Encripted seed phrase will be saved in wallet.dat file. To avoid entering password every time you run the node it is recommended to specify it in wallet section of the node configuration file.

# Creating Wallet Using Existing Seed

If you already have a seed, then input the following parameters in the wallet section of node's configuration file:

  • base58-encoded seed.
  • password.

If necessary, change the path to directory where the generated wallet.dat must be placed. wallet section example with described settings is provided below:

wallet {
    file = ${waves.directory}"/wallet/wallet.dat"
    password = "some-string-as-password"
    seed = "base58-encoded-seed"
}

As a result, the wallet.dat will be generated in the selected directory based on the existing seed.

# Using Existing Wallet

If you already have the wallet.dat created before, then just put it in the directory listed in the wallet section, and specify a password for it with the password parameter. Additional actions are not required.

# Updating Wallet's Settings

If you want to run the node with another wallet, use one of the following instuctions:

  • Replace wallet.dat file with the file which contains SEED phrase of another wallet.

OR

  • Delete/move to another location your wallet.dat file to empty /wallet directory. Then update SEED in config file.

After restarting the node will use another wallet settings.

# Changing node's account

If you need to change node's account, first of all, delete the existing wallet.dat. After that, you can:
