Direct encrypted P2P communication between OpenClaw instances via Yggdrasil IPv6.

No servers. No middlemen. Every message goes directly from one OpenClaw to another.

How it works

Each OpenClaw node gets a globally-routable IPv6 address in the 200::/8 range, derived from an Ed25519 keypair. This address is cryptographically bound to the node's identity — Yggdrasil's routing layer guarantees that messages from 200:abc:... were sent by the holder of the corresponding private key.

Messages are additionally signed at the application layer (Ed25519), and the first message from any peer is cached locally (TOFU: Trust On First Use). Subsequent messages from that peer must use the same key.

Node A (200:aaa:...)   ←——— Yggdrasil P2P ———→   Node B (200:bbb:...)
  OpenClaw + plugin                                  OpenClaw + plugin

Prerequisites

• OpenClaw installed
• Yggdrasil installed and on PATH
  • macOS: brew install yggdrasil
  • Linux: see official instructions

Install

openclaw plugins install @resciencelab/declaw

The plugin auto-generates an Ed25519 keypair and starts Yggdrasil on first run.

Usage

# See your Yggdrasil address (share this with peers)
openclaw p2p status

# Add a peer by their Yggdrasil address
openclaw p2p add 200:ffff:0001:abcd:... --alias "Alice"

# Check if a peer is reachable
openclaw p2p ping 200:ffff:0001:abcd:...

# Send a direct message
openclaw p2p send 200:ffff:0001:abcd:... "Hello from the decentralized world!"

# List known peers
openclaw p2p peers

# Check inbox
openclaw p2p inbox

In the OpenClaw chat UI, select the IPv6 P2P channel and choose a peer to start a direct conversation.

Slash commands:

• /p2p-status — show node status
• /p2p-peers — list known peers

Configuration

{
  "plugins": {
    "entries": {
      "ipv6-p2p": {
        "enabled": true,
        "config": {
          "peer_port": 8099,
          "data_dir": "~/.openclaw/ipv6-p2p",
          "yggdrasil_peers": []
        }
      }
    }
  }
}

Architecture

~/.openclaw/ipv6-p2p/
├── identity.json          Ed25519 keypair + derived addresses
├── peers.db               SQLite — known peers + TOFU public key cache
└── yggdrasil/
    ├── yggdrasil.conf     Stable keypair (survives restarts)
    └── yggdrasil.log      Daemon logs

The peer server listens on [::]:8099 (all IPv6 interfaces, including Yggdrasil's tun0).

Trust model

• Network layer: TCP source IP must be in 200::/8 (Yggdrasil-authenticated)
• Body check: from_ygg in request body must match TCP source IP
• Signature: Ed25519 signature verified against sender's public key
• TOFU: First message from a peer caches their public key; subsequent messages must match
