Monolith — Crypto Wallet Skill

Secure crypto wallet for OpenClaw agents. Monolith combines hardware-isolated keys (Apple Secure Enclave), on-chain spending controls, and policy-gated approvals so agents can transact safely without exposing private keys.

send <to> <amount> [token] [chainId]	Send ETH or USDC	Yes
swap <amountETH> [tokenOut] [chainId]	Swap ETH for tokens via Uniswap (Routing API with on-chain fallback)	Yes
balance <address> [chainId]	Check ETH and stablecoin balances	No (read-only)
capabilities	Show current limits, budgets, gas status	Yes
decode <target> <calldata> <value>	Decode a tx intent into human-readable summary	Yes
panic	Emergency freeze — instant, no Touch ID	Yes
status	Check daemon health and wallet info	Yes
identity [query|register]	ERC-8004 identity operations	Partially
setup	Run setup wizard, show wallet status and config	Yes
policy	Show current spending policy	Yes
policy update '<json>'	Update spending policy (Touch ID required)	Yes
allowlist <add|remove> <address> [label]	Add or remove address from allowlist (Touch ID required)	Yes
audit-log	Show the daemon audit log	Yes

Security Model

• The skill is untrusted. It only builds intents: {target, calldata, value}.
• The skill NEVER sets nonce, gas, chainId, fees, or signatures.
• The signing daemon (local macOS process) enforces all policy.
• Transactions within policy limits execute automatically (autopilot).
• Transactions that exceed limits or use unknown calldata require human approval via 8-digit code.
• Token approvals (approve, permit, etc.) ALWAYS require explicit approval.

What requires approval?

• Transfers over per-tx or daily spending caps
• Transfers to non-allowlisted addresses
• Token approvals (approve, permit, setApprovalForAll)
• Unknown calldata (default-deny policy)
• Swaps above slippage limits

What works on autopilot?

• ETH and USDC transfers within limits to allowlisted addresses
• Swaps on allowlisted DEXes (Uniswap) within slippage limits
• DeFi deposits/withdrawals on allowlisted protocols (Aave)
• Balance checks, status queries, decode requests

Setup

1. Install Monolith from ClawHub: clawhub install monolith
2. Start a new OpenClaw session so the skill is loaded.
3. Install local macOS components from the install entries:
   • MonolithDaemon-v0.1.5.pkg (admin/root install)
   • MonolithCompanion.app.zip (extract app to /Applications and open once)
4. Start daemon first, then companion. If companion was opened before daemon, restart companion after daemon is running.
5. Run monolith setup to verify daemon/companion connectivity and wallet status.
6. Fund the wallet address with ETH on your chosen chain.
7. Start transacting.

First-Install Notes (OpenClaw bot/operator)

• Approval flows (Touch ID + notifications) require an active logged-in macOS GUI session.
• Headless-only SSH sessions cannot complete biometric/notification approval steps.
• monolith setup is the canonical health check before attempting send, swap, policy, or allowlist commands.

Error Handling

• If the daemon is not running, all signing commands will fail with a clear error
• If gas is low, the daemon will refuse transactions — fund the wallet with more ETH
• If the wallet is frozen, no outbound transactions are possible until unfrozen (requires Touch ID + 10min delay)
• Rate-limited by Pimlico? The daemon uses exponential backoff automatically

Approval Flow

When a transaction exceeds policy limits or uses unknown calldata, the daemon returns HTTP 202 with a reason, summary, and expiration. The agent should:

1. Present the approval reason and summary to the user.
2. Ask the user for the 8-digit approval code (displayed by the daemon's native macOS dialog).
3. Re-call /sign with the same intent plus the approvalCode field to confirm.

No separate approval script is needed -- the same send or swap command is re-invoked with the approval code passed through the daemon.

Swap Routing

Uses Uniswap Routing API when available; falls back to on-chain V3 fee-tier probing (tries 3000, 500, 10000 bps tiers, picks best quote). The fallback ensures swap intents can still be built when the API is down or returns unexpected results.

Chains

• Ethereum Mainnet (chainId 1)
• Base (chainId 8453)
