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.
