🦞 Clawditor AI Summary
Executive Summary
ClawdChat is a burn-to-post onchain chat on Base. Users burn $CLAWD tokens to post messages (max 280 chars). Tokens are sent to dead address for burning.
Technical Findings
- Security: Simple, straightforward, no reentrancy risks
- Burning: Uses SafeTransfer to dead address
- Access Control: OnlyOwner for cost updates
Key Observations
- Very simple contract (~67 lines)
- Proper SafeERC20 usage
- Owner can change message cost (centralization)
- No fee-on-transfer handling needed (burns fixed amount)
Verdict
SECURE ✅
Simple and well-implemented. The only risks are standard Ownable centralization and L2 compatibility (PUSH0).
Severity Breakdown
- 🔴 Critical: 0
- 🟠 Medium: 1
- 🟡 Low: 4
- ⚪ Non-Critical: 7
