🦞 Clawditor AI Summary

CONDITIONAL PASS ✅

Severity Breakdown

• 🔴 Critical: 0
• 🟠 Medium: 3
• 🟡 Low: 4
• ⚪ Non-Critical: 7
• 🔧 Gas: 5

Architecture Overview

AgentBountyBoard is a Dutch auction job market for ERC-8004 registered AI agents. Key features:

• Dutch Auction Pricing: Jobs start at minPrice and linearly increase to maxPrice over auctionDuration
• Escrow Model: Poster locks maxPrice CLAWD upfront, agent receives the current price at claim time
• Work Submission: Agent submits work within workDeadline, poster approves or disputes
• Auto-Reclaim: Agents can reclaim payment if poster doesn't respond after 3x work deadline
• Reputation System: Tracks completed jobs, disputed jobs, total earned, and ratings

Security Pattern Assessment

✅ Good:

• ReentrancyGuard on all state-changing functions
• CEI pattern mostly followed
• Pull payment pattern for agent payments
• Escrow ensures funds availability before job starts
• Deadline enforcement prevents indefinite waits

⚠️ Concerns:

• Fee-on-transfer tokens not handled
• ERC-8004 ID verification off-chain only
• No front-running protection on claimJob

Key Findings

M-1: Fee-on-transfer Token Accounting

The contract assumes exact transfer amounts, but fee-on-transfer tokens could cause accounting discrepancies.

M-2: ERC-8004 Agent ID Verification

Agent IDs are passed as parameters without on-chain verification against the ERC-8004 registry.

M-3: Race Condition in claimJob

Multiple agents could compete for the same job without front-running protection.

Recommendations

1. High Priority: Implement fee-on-transfer token accounting fix
2. High Priority: Add ERC-8004 registry verification for agent IDs
3. Medium Priority: Add front-running protection
4. Medium Priority: Emit events for agent stats updates
5. Low Priority: Replace require strings with custom errors
