Arc Security - Agent Trust Protocol

Chain-agnostic security infrastructure for OpenClaw skills. Auditors stake USDC to vouch for skill safety, users pay micro-fees to access verified skills, and malicious skills get slashed through decentralized governance -- all powered by CCTP on Arc.

Installation

clawhub install arc-security

Configuration

Set the following environment variables:

| Variable | Required | Description | |---|---|---| | ARC_RPC_URL | Yes | Arc testnet RPC endpoint (default: https://testnet-rpc.arc.network) | | CONTRACT_ADDRESS | Yes | Deployed SkillSecurityRegistry contract address | | PRIVATE_KEY | Yes | Wallet private key (for signing transactions) | | X402_SERVER_URL | Yes | x402 payment server URL | | ETH_RPC_URL | No | Ethereum Sepolia RPC (for cross-chain operations) | | BASE_RPC_URL | No | Base Sepolia RPC (default: https://sepolia.base.org) | | ARB_RPC_URL | No | Arbitrum Sepolia RPC (default: https://sepolia-rollup.arbitrum.io/rpc) |

Commands

check -- Check skill trust status

Query on-chain bond status, auditor count, usage stats, and computed trust score for any skill.

clawhub arc-security check <skill_id>

Example output:

Skill: youtube-downloader
├─ Bonded: 100.00 USDC by 3 auditors
├─ Used: 1,250 times
├─ Trust Score: 75/100
├─ Status: Safe to use
└─ Created: 2025-06-15 14:30:00

Trust Score is calculated as:

• 40% from bond amount (capped at 100 USDC = full weight)
• 40% from usage count (capped at 1,000 uses = full weight)
• 20% from auditor count (5 points per auditor)
• Flagged skills receive a -50 penalty

use -- Pay and download a skill

Pays the 0.10 USDC usage fee via x402 and downloads the skill package. Automatically selects the cheapest payment path based on your wallet balances.

clawhub arc-security use <skill_id>

Payment chain selection priority:

1. Arc Testnet (direct -- no bridging fees)
2. Base Sepolia (via CCTP)
3. Arbitrum Sepolia (via CCTP)
4. Ethereum Sepolia (via CCTP)

bond -- Stake USDC to vouch for a skill

Stake USDC as a security bond to vouch for a skill's safety. If the skill is found malicious, 50% of your stake is slashed.

clawhub arc-security bond <skill_id> <amount> <source_chain>

Arguments:

• skill_id -- Skill identifier
• amount -- Amount of USDC to stake (e.g. 50)
• source_chain -- Chain to pay from (ethereum-sepolia, base-sepolia, arbitrum-sepolia, arc-testnet)

Example:

clawhub arc-security bond youtube-downloader 50 base-sepolia

report -- Report a malicious skill

Submit a claim that a skill is malicious. Requires a 1 USDC anti-spam deposit (refunded if the claim is validated).

clawhub arc-security report <skill_id> --evidence <ipfs_hash>

Example:

clawhub arc-security report bad-skill --evidence QmXyz123...

Opens a 72-hour voting window for auditors.

vote-claim -- Vote on a pending claim

Cast a vote on whether a reported skill is malicious. Only wallets that have staked on any skill are eligible to vote. Vote weight is based on total stake and audit track record.

clawhub arc-security vote-claim <claim_id> <support|oppose>

Vote weight formula: sqrt(totalStaked) * (successfulAudits / totalAudits)

claim-earnings -- Withdraw accumulated fees

Withdraw your share of usage fees earned as an auditor. Fees are split 70% to auditors (proportional to stake) and 30% to the insurance pool.

clawhub arc-security claim-earnings <destination_chain>

Supported destination chains:

• arc-testnet (direct transfer)
• ethereum-sepolia, base-sepolia, arbitrum-sepolia (via CCTP)

Supported Chains

| Chain | CCTP Domain | Payment | Bonding | Earnings | |---|---|---|---|---| | Arc Testnet | 100 | Direct | Direct | Direct | | Ethereum Sepolia | 0 | CCTP | CCTP | CCTP | | Base Sepolia | 6 | CCTP | CCTP | CCTP | | Arbitrum Sepolia | 3 | CCTP | CCTP | CCTP |

Fee Structure

| Action | Cost | Distribution | |---|---|---| | Use a skill | 0.10 USDC | 70% auditors, 30% insurance pool | | Submit a claim | 1.00 USDC deposit | Refunded if claim validated | | Guilty verdict | 50% of bond slashed | 80% to victim, 20% to insurance |
