Node of COC testnet

Dev Tools

Operate COC (ChainOfClaw) blockchain nodes — install, start, stop, monitor, and remove validator, fullnode, archive, gateway, and dev nodes. Use when the user wants to run a COC node, inspect the status of a running node (block height, peer count, BFT state), view node logs, edit node-config.json, or probe RPC endpoints. Also covers preparing a machine to provide ≥ 256 MiB of P2P storage to the COC network. **Smooth out-of-box experience (1.2.0+):** read-only commands (list / status / coc-rpc-query against an installed node) work immediately after `openclaw plugins install` with zero config; the activation banner reports `data dir`, `storage quota`, `tracked nodes`, and `coc repo` status so the operator sees at a glance what works now and what (if anything) needs config to unlock install/start. Data dir auto-resolves to a writable path along the same chain @chainofclaw/claw-mem and @chainofclaw/soul use (`config.dataDir → $COC_NODE_DATA_DIR → $CLAW_MEM_DATA_DIR/coc-node → $OPENCLAW_STATE_DIR/coc-node → ~/.claw-mem/coc-node`); legacy `~/.chainofclaw/nodes.json` from pre-1.2.0 installs is detected as a fallback. Fail-fast actionable EACCES at activation rather than silent breakage mid-command. Starting / installing a node additionally requires a local clone of the COC source repo (set $COC_REPO_PATH or `bootstrap.cocRepoPath`); the activation banner tells you whether one was auto-detected.

Install

openclaw skills install coc-node

coc-node — COC blockchain node lifecycle

Operate a COC node on this machine. The skill is backed by the npm package @chainofclaw/node which ships both a standalone coc-node CLI and an OpenClaw plugin (skill id coc-node).

What this skill can do

Install a new COC node of any type: validator, fullnode, archive, gateway, or dev
Start / stop / restart nodes; follow logs across the node / agent / relayer streams
Report status — block height, peer count, BFT activity, process PID, per-service health
Edit a node's node-config.json in $EDITOR
Probe any COC RPC endpoint safely (whitelisted methods only: eth_blockNumber, eth_getBlockByNumber, net_peerCount, coc_chainStats, coc_getBftStatus, eth_syncing, eth_chainId, …)

Zero-config on install (1.2.0+)

Everything you can do without a COC source repo works immediately after openclaw plugins install — no further setup. The activation banner makes it explicit:

[coc-node] data dir: /home/<you>/.claw-mem/coc-node
[coc-node] storage quota: advertised=256 MiB, reserved=256 MiB, enforce=true
[coc-node] tracked nodes: 0
[coc-node] coc repo: detected at /home/<you>/COC — install/start commands enabled
[coc-node] Loaded — no nodes yet, run `openclaw coc-node node install <name>` to add one
[coc-node] CLI is mounted at `openclaw coc-node ...`. ...

Or, if no COC repo is on this machine:

[coc-node] coc repo: not detected — read-only mode (list / status / coc-rpc-query work; install / start need bootstrap.cocRepoPath or $COC_REPO_PATH pointing at a COC source clone)

That second line is the only thing you need to read to know whether node install / node start will work. Everything else (list, status, log inspection, RPC probes against an already-running node) is unconditionally available.

Data directory

Auto-resolves to a writable path along a chain that's intentionally aligned with @chainofclaw/claw-mem and @chainofclaw/soul so the three plugins share one operator-managed root. Priority (highest first):

config.dataDir (per-instance plugin config)
$COC_NODE_DATA_DIR (coc-node-specific operator override)
$CLAW_MEM_DATA_DIR/coc-node (shared with claw-mem + soul — set this once and all three move together)
$OPENCLAW_STATE_DIR/coc-node (sandbox-managed state dir)
~/.claw-mem/coc-node (default — shared root with claw-mem + soul)
~/.chainofclaw (legacy pre-1.2.0 fallback; only picked when nodes.json already exists there)

Fails fast at activation with an actionable EACCES error naming each tried path, rather than silently breaking mid-command. /tmp is intentionally not a fallback.

What needs setup to start a node yourself

Actually starting a node process requires the COC source repository (it spawns node/src/index.ts from there). Tell the skill where the repo is via one of:

COC_REPO_PATH environment variable (simplest)
bootstrap.cocRepoPath in plugin config
Run inside (or anywhere under) the COC repo — auto-discovered via marker files
Place a clone at ~/COC — also auto-discovered

Plus ≥ 256 MiB free disk for the P2P storage reservation (mandatory COC network entry requirement).

The activation banner tells you whether the auto-detection succeeded. If COC_REPO_PATH is unset and no clone is at ~/COC, node install and node start fail with a clear error pointing here — list / status / log / RPC commands keep working.

Relationship with claw-mem and coc-soul

The three @chainofclaw/* skills are fully decoupled at the npm-dependency level. Each can be installed independently. They cooperate through shared on-disk conventions, not through code coupling:

Skill	Owns	What it adds when paired
coc-node	Local node lifecycle (install / start / stop / status / RPC probe)	Independent of the other two.
claw-mem2db	Persistent agent memory (chat + tool capture, FTS5 search, hybrid recall)	Pure agent-side; doesn't touch the chain. coc-node doesn't read or write to its DB.
coc-soul	On-chain DID, IPFS backup, guardian recovery, carrier resurrection	Reads claw-mem's SQLite DB (when present) for semantic snapshots. Also independent of coc-node.

Shared dataDir convention. All three default to writing under ~/.claw-mem (or under $CLAW_MEM_DATA_DIR / $OPENCLAW_STATE_DIR), each in a scoped subdirectory:

claw-mem → ~/.claw-mem/{claw-mem.db, config.json, ...}
coc-soul → ~/.claw-mem/keys/agent.key
coc-node → ~/.claw-mem/coc-node/{nodes.json, <node>/...}

So one CLAW_MEM_DATA_DIR=/somewhere/writable env var moves all three. Operators in sandboxed Docker hosts (where ~/.claw-mem is read-only) only have one knob to turn.

How to invoke

Inside OpenClaw (recommended — works automatically after plugins install):

openclaw coc-node node install --type fullnode --network testnet
openclaw coc-node node list
openclaw coc-node node status
openclaw coc-node node logs <name> --follow --all

Standalone bin (only if you ran npm i -g @chainofclaw/node separately):

coc-node node install --type dev --network local --name dev-1 --rpc-port 28780
coc-node node list

openclaw plugins install does NOT install the standalone coc-node binary into your PATH. Use openclaw coc-node ... (with the openclaw prefix), or install the bin globally via npm if you want the bare command.

Typical flows

Spin up a dev node against local hardhat — coc-node node install --type dev --network local then coc-node node start dev-1.
Join testnet as a fullnode — coc-node node install --type fullnode --network testnet --rpc-port 28780 then coc-node node start.
Stand up a validator — coc-node node install --type validator --network testnet --advertised-bytes 1073741824 (1 GiB storage contribution).
Diagnose a flaky node — coc-node node status (snapshot) → coc-node node logs --follow (tail) → coc-node node config show (inspect config) → coc-node node restart if needed.
Decommission a node — coc-node node stop NAME then coc-node node remove NAME --yes (delete data) or coc-node node remove NAME --yes --keep-data.

When NOT to use this skill

Deploying COC smart contracts — that's a contracts/ hardhat / script task, not node lifecycle.
On-chain identity / backup / recovery — use the coc-soul skill.
Agent memory / session capture — use the claw-mem2db skill.
