Networks

A Farcaster account must choose which network it posts its messages to. Any account registered in the contracts can post to any network. But messages posted in one network are not visible in any other network.

There are two main networks:

• Testnet - the latest beta release intended for developers
• Mainnet - the stable version that everyone uses

When installing your hub, you'll need to choose a network to connect to.

Testnet

Testnet is a sandbox environment for developers to test new features. Dummy messages are broadcast every 10 seconds to simulate activity.

Set the following variables in your .env file in apps/hubble:

FC_NETWORK_ID=2
BOOTSTRAP_NODE=/dns/testnet1.farcaster.xyz/tcp/2282

If running from source code, add these arguments to the yarn start command

yarn start ... \
    -n 2 \
    -b /dns/testnet1.farcaster.xyz/tcp/2282

Mainnet

Mainnet is the production environment that everyone uses.

Set the following variables in your .env file in apps/hubble:

FC_NETWORK_ID=1
BOOTSTRAP_NODE=/dns/hoyt.farcaster.xyz/tcp/2282

If running from source code, add these arguments to the yarn start command

yarn start ... \
    -n 1 \
    -b /dns/hoyt.farcaster.xyz/tcp/2282
