# Join a network

It is highly recommended that you set up a local private network before joining a public network. This will help get familiar with the setup process, and provide an environment for testing. The following sections outline this process. If you want to join a public network without setting up a private network, you can skip to join a public network .

# Set up a local private network

Validators can set up a private Terra network to become familiar with running a full Terra node before joining a public network.


If you are a developer and want to set up a local, WASM-enabled, private testnet for smart contracts, visit Download LocalTerra.

# Create a single node

The simplest Terra network you can set up is a local testnet with just a single node. In a single-node environment, you have one account and are the only validator signing blocks for your private network.

  1. Initialize your genesis file that will bootstrap the network. Replace the following variables with your own information:
terrad init --chain-id=<testnet-name> <node-moniker>
  1. Generate a Terra account. Replace the variable with your account name:
terrad keys add <account-name>

Get tokens

In order for Terrad to recognize a wallet address, it must contain tokens. For the testnet, use the faucet (opens new window) to send Luna to your wallet. If you are on mainnet, send funds from an existing wallet. 1-3 Luna are sufficient for most setup processes.

# Add your account to the genesis

Run the following commands to add your account and set the initial balance:

terrad add-genesis-account $(terrad keys show <account-name> -a) 100000000uluna,1000usd
terrad gentx <my-account> 10000000uluna --chain-id=<testnet-name>
terrad collect-gentxs

# Start your private Terra network

Run the following command to start your private network:

terrad start

If the private Terra network is set up correctly, your terrad node will be running on tcp://localhost:26656, listening for incoming transactions, and signing blocks.

# Join a public network

These instructions are for setting up a brand new full node from scratch. You can join a public Terra network, such as the Columbus mainnet or Bombay testnet, by completing the following steps:

# 1. Select a network

Specify the network you want to join by choosing the corresponding genesis file and seeds:

Network Type Genesis Addressbook
columbus-5 Mainnet Genesis Link (opens new window) Addressbook Link (opens new window)
bombay-12 Testnet Genesis Link (opens new window) Addressbook Link (opens new window)

Selecting a network

Note that the versions of the network listed above are the latest versions (opens new window). To find earlier versions, please consult the networks repo (opens new window).

# 2. Download genesis file and address book

Genesis-transaction specifies the account balances and parameters at the start of the network to use when replaying transactions and syncing.

Addressbook lists a selection of peers for your node to dial to in order to discover other nodes in the network. Public address books of peers are made available by the Terra community.

Choose a testnet or mainnet address type and download the appropriate genesis-transaction and addressbook. Links to these are posted in Select-a-network.

  • For default terrad configurations, the genesis and addressbook files should be placed under ~/.terra/config/genesis.json and ~/.terra/config/addrbook.json respectively.


# Obtain the genesis for the bombay-12 testnet:
wget https://raw.githubusercontent.com/terra-money/testnet/master/bombay-12/genesis.json -I ~/.terra/config/genesis.json

# Obtain the addressbook for the bombay-12 testnet:
wget https://raw.githubusercontent.com/terra-money/testnet/master/bombay-12/addrbook.json -O ~/.terra/config/addrbook.json

# 3. terrad start

Start the network and check that everything is running smoothly:

terrad start
terrad status
# It will take a few seconds for terrad to start.

Your node is now syncing. This process will take a long time. Make sure you've set it up on a stable connection so you can leave while it syncs.
