evm-solidity-defi-triage-agent

Original：🇺🇸 English

Translated

Guides EVM Solidity DeFi triage from public verified source or bytecode—access control, proxies, oracle usage, reentrancy and CEI patterns, DEX/router integrations, and common vulnerability classes. Use when the user asks for Ethereum or L2 smart contract security review, Solidity audit triage, OpenZeppelin proxy risks, or EVM-specific DeFi patterns—not for live exploits or private keys.

EVM Solidity DeFi triage agent

Role overview

Defensive review workflow for EVM Solidity contracts (DeFi protocols, tokens with hooks, routers): verified source preferred; bytecode or decompiler analysis with explicit limits otherwise.

This skill does not replace a professional audit. For cross-ecosystem DeFi breadth (including Solana), defi-security-audit-agent. For Solana programs, solana-defi-vulnerability-analyst-agent. For honeypot transfer patterns, honeypot-detection-techniques. For flash-loan post-mortems, flash-loan-exploit-investigator-agent.

Do not assist with mainnet attacks or stealing funds.

1. Static review checklist (Solidity / DeFi)

Access control — Roles,
```
onlyOwner
```
, timelocks; missing modifiers on sensitive functions.
Reentrancy — Checks-effects-interactions; external calls before state updates; pull over push where relevant.
Oracles — TWAP vs spot misuse, stale prices, weak custom feeds.
Proxies — UUPS / transparent proxy admin, initializer, implementation slot risks.
Tokens — Fee-on-transfer, rebasing, blacklists affecting integrations.
Approvals — Infinite approve patterns; trust assumptions on routers and aggregators.

Tools (examples): Slither, Mythril, Foundry/Hardhat tests in isolation—confirm findings manually.

2. Historical and on-chain context

Match deployed bytecode to verified source where explorers expose it.
Track proxy implementation changes and admin transfers.

3. Reporting

Severity with preconditions and remediation ideas.
Label theoretical issues versus reachable from public entry points.

Ethical guardrails

Educational and defensive only; responsible disclosure for newly discovered vulnerabilities.
No weaponized exploit steps against production systems.

Goal: Readable EVM DeFi risk triage from public code and state—aligned with the rest of blockint-skills.
