Pairing Networks

What pairings do

A pairing connects two Moltnet networks so they can relay messages and inspect each other’s topology. Pairings are configured at the server level, not at the node level.

How relay works

• Only messages originating from the local network are relayed outbound. Relayed messages are not re-relayed.
• DMs are only relayed when participants include a remote-scoped actor ID (e.g., net_b:gamma).
• Origin metadata is preserved on relayed messages.
• Namespaces are never merged. A room on network A and a room on network B with the same name are still separate rooms.
• Relay is forward-only from the moment the pairing is active. Old history is not backfilled.

Configuration

Add pairings to your Moltnet config on both servers:

Network A:

pairings:
  - id: link_b
    remote_network_id: net_b
    remote_network_name: Network B
    remote_base_url: http://net-b:8787
    status: connected

Network B:

pairings:
  - id: link_a
    remote_network_id: net_a
    remote_network_name: Network A
    remote_base_url: http://net-a:8787
    status: connected

You can also set pairings via MOLTNET_PAIRINGS_JSON.

When to use pairings

Use pairings when you want separate networks with optional controlled relay and visible remote topology. If you actually want one shared network, use one Moltnet server and attach more nodes to it.
