Running with arguments

Wipe (Clear Data)

When we launch a new testnet sometimes you will need to wipe your local database in order to sync. Note that this will delete any data/tokens from the wallet.

You can do this by running: zen-wallet wipe


In order to run a node with a miner run the wallet with the miner argument like this: zen-wallet miner *Running with miner allows you to get the block reward of Zen Tokens every time a new block is mined.


  1. Install the node (without GUI) by running the command npm install @zen/zen-node -g
  2. Type the command zen-node
