# Live Networks

This document provides an overview of live networks currently running the regen-ledger blockchain application and how to interact with a live network using the regen binary.

By default, the regen binary will connect to a local node. In order to connect to a live network, you'll need to know the address of a public node.

# Available Networks

# Regen Mainnet

regen-1 is the chain ID for Regen Mainnet.

Regen Mainnet launched with the v1.0.0 release tag of regen-ledger.

When starting a full node or a validator node from genesis, you will need to start the node with the v1.0.0 version (the "genesis binary"). For more information about preparing your node to migrate to the v2.0.0 version, see Upgrade Guide v2.0.

The following URL is the node address for a full node operated by VitWit:

http://104.131.169.70:26657/ (opens new window)

For more information, see regen-network/mainnet (opens new window).

# Redwood Testnet

regen-redwood-1 is the chain ID for Redwood Testnet.

Redwood Testnet launched with the v1.0.0 release tag of regen-ledger.

When starting a full node or a validator node from genesis, you will need to start the node with the v1.0.0 version (the "genesis binary"). For more information about preparing your node to migrate to the v2.0.0 version, see Upgrade Guide v2.0.

The following URL is the node address for a full node operated by RND:

http://redwood.regen.network:26657/ (opens new window)

For more information, see regen-network/testnets (opens new window).

# Hambach Testnet

regen-hambach-1 is the chain ID for Hambach Testnet.

Hambach Testnet launched with the v2.0.0-beta1 release tag of regen-ledger using the experimental build (EXPERIMENTAL=true).

When the time comes to introduce new experimental features, Hambach Testnet will be restarted with an incremented chain ID rather than going through the upgrade process due to the inability to support migrations for experimental modules. It's important to keep this in mind when developing with Hambach Testnet and we recommend creating scripts that can be used to reseed the network following a restart.

The following URL is the node address for a full node operated by RND:

http://hambach.regen.network:26657/ (opens new window)

For more information, see regen-network/testnets (opens new window).

# Interacting With A Node

First, you'll need to install the regen binary. For installation instructions, see Install Regen.

In order to interact with a node from a live network, you'll need to provide a --node flag with a valid node address to your commands. Before submitting any queries or transactions, you should first check the status of the node using the status command.

To check the status of the Regen Mainnet node, run the following command:

regen status --node http://104.131.169.70:26657

To check the status of the Redwood Testnet node, run the following command:

regen status --node http://redwood.regen.network:26657

To check the status of the Hambach Testnet node, run the following command:

regen status --node http://hambach.regen.network:26657

If you are using v2.0.0 or later, you can set the node address once using the config command rather than adding the --node flag to each command.

regen config node http://104.131.169.70:26657

You can check the configuration by running the following command:

regen config
