Networks ​

When installing your hub, you'll need to choose a network to connect to. We recommend starting with testnet if this is your first time, and migrating to mainnet when you've got it working.

Testnet ​

A Testnet Hub connects to a sandbox, where dummy messages are broadcast every 10 seconds. You'll need 4GB RAM and 5 GB of free space to operate a testnet hub.

  1. Set the following variables in your .env file:
sh
FC_NETWORK_ID=2
BOOTSTRAP_NODE=/dns/testnet1.farcaster.xyz/tcp/2282

Mainnet ​

A Mainnet Hub connects to the production environment used by all apps on the network. You will need 8GB RAM and 20 GB of disk space to operate a mainnet hub.

  1. Update the .env file in your apps/hubble directory, substituting the relevant value for your ETH_RPC_URL:
sh
FC_NETWORK_ID=1
BOOTSTRAP_NODE=/dns/nemes.farcaster.xyz/tcp/2282
  1. Get your PeerId from the file apps/hubble/.hub/<PEER_ID>_id.protobuf
  2. Make a PR to add it to the allowed peers list
  3. Once merged, other Hubs will start peering with you after 1 hour.
