# Create a Validator
This document provides instructions for creating a validator on Regen Mainnet, Redwood Testnet, and Hambach Testnet.
This assumes that you already have a full node running.
# Add Validator Key
As a validator who signs blocks, your node must have a public/private key pair. Regen Ledger keys can be managed with the
regen keys subcommand. A new key pair can be generated using:
regen keys add [name]
If you create a new key, make sure you store the mnemonic phrase in a safe place. You will not be able to recover your new key without the mnemonic phrase.
If you'd like to use an existing key or a custom keyring backend, you can find more information about adding keys and keyring backends in the Cosmos SDK Keyring (opens new window) documentation.
# Create Validator
The next step will be to create a validator. You will need to have enough REGEN tokens to stake and to submit the transaction. For more information about the REGEN token, see the token page (opens new window).
You'll want to carefully consider the options you set when creating a validator.
Submit a transaction to create a validator:
regen tx staking create-validator \ --amount=<stake_amount> \ --pubkey=$(regen tendermint show-validator) \ --moniker="<node_moniker>" \ --chain-id=<chain_id> \ --commission-rate="0.10" \ --commission-max-rate="0.20" \ --commission-max-change-rate="0.01" \ --min-self-delegation="1" \ --gas="auto" \ --from=<key_name>
