Multi-AI Security Audit Report
Hydro2coin (HY2CO) Smart Contract
Claude Sonnet 4.5
GPT-4.1 (OpenAI)
GPT-5 (OpenAI)
Gemini 2.5 Pro
1. Executive Summary
✓Overall Code Risk: Low (No critical code issues found)
⚠Operational Risk: Medium (centralization, unverified deployment, no audit)
Key strengths:
- OpenZeppelin libraries (ERC20, Burnable, Ownable2Step) with well-audited code
- No mint post-deployment and no honeypot/blacklist/hidden tax code
- Two-step ownership for safety; owner-only recovery features
- Standard Uniswap V2 integration; Solidity 0.8.x overflow protection
- No third-party professional audit (all AIs flag as high priority)
- Centralized ownership and supply at deployment
- Non-upgradeable; risks cannot be patched after go-live
2. Participating AI Models

4. Multi-AI Security Comparison
| Aspect | Claude | GPT-4.1 | GPT-5 | Gemini | Consensus |
|---|---|---|---|---|---|
| Reentrancy | ✓ | ✓ | ✓ | ✓ | Protected |
| Overflow/Underflow | ✓ | ✓ | ✓ | ✓ | Protected |
| Access Control | ✓ | ✓ | ✓ | ✓ | Proper |
| OpenZeppelin | ✓ | ✓ | ✓ | ✓ | Strong |

| DEX Integration | Uniswap | Uniswap | Uniswap | Uniswap | Standard |
| Upgradeability | No | No | No | No | Not upgradable |
| 3rd-Party Audit | None | None | None | None | Missing |
5. Consensus Findings
- ✓All AIs: No critical vulnerabilities or scam logic found
- ✓Mint only on deploy, with no owner minting after
- ✓Honeypot and transfer block patterns: none present
- ✓Owner can recover stuck tokens (only from contract address)
- ✓Uniswap router/pair: industry-standard usage, one-time setup
- ⚠Key risks: Centralization, no formal audit, non-upgradable
6. Unique AI Insights
Claude: Static safety review, access control, SafeERC20, event transparency, internal vs external call analysis.
GPT-4.1: Owner renounce disables privileged functions, distinct recovery for HY2CO vs foreign tokens.
GPT-5: No honeypot indicators, guides for router/pair address verification, deployer-must-be-contract enforcement.
Gemini Pro: Strong risk ranking (no audit = high), highlights ownership and non-upgradeable contract concerns, notes license absence.
7. Recommendation Matrix
| Recommendation | Claude | GPT4.1 | GPT-5 | Gemini |
|---|---|---|---|---|
| Get pro audit | Yes | Yes | Yes | CRITICAL |
| Verify router/live state | - | - | YES | - |
| Multisig/time-lock | YES | - | - | - |
| LP lock/public tx docs | - | - | YES | - |
| Owner renunciation | - | YES | - | - |
8. Owner Privilege Deep-Dive
- recoverToken: Owner can recover stuck HY2CO from contract; disables with renounce.
- recoverForeignERC20: Owner can recover non-HY2CO tokens; disables with renounce.
- afterConstructor: One-time Uniswap V2 pair/router setup, emits event for transparency.
- setAMM: Flagging has no current effect on transfer/trading.
- Two-step ownership: Prevents accidental loss; renounce disables all owner-only functions forever.
9. Operational vs Code-Level Risk
Code-Level: Low (all AIs)Operational: Medium (centralization, no audit, live config)
10. Limitations
- Static code review only—no dynamic/exploitable behavior can be guaranteed absent!
- No legal/financial/investment advice.
- No assessment of economic manipulation or team legitimacy.
- AIs cannot guarantee future security or account for all off-chain risks.
