General Solidity/EVM security checklist — non-obvious footguns that apply to every smart contract. Covers external calls, force-feeding, pause mechanisms, read-only reentrancy, merkle trees, code asymmetry, multicall hazards, and general EVM quirks. Load this for EVERY audit.
Oracle vulnerabilities including Chainlink staleness, minAnswer/maxAnswer circuit breakers, L2 sequencer uptime, TWAP manipulation, VRF front-running, spot price attacks, peg assumptions, and oracle decimal mismatches. Load when the contract uses any price oracle or external data feed.
EVM smart contract audit checklist for non-obvious access control issues. Covers centralization risks, privilege escalation, two-step ownership, role management, and admin rug vectors. Use when auditing protocols with privileged roles, admin functions, or governance. Load references/checklist.md for the full checklist.
Inline assembly, CREATE/CREATE2, EXTCODESIZE, and low-level opcode vulnerabilities. Covers metamorphic contracts, constructor-time code absence, assembly math overflow, and div-by-zero returning 0. Load when the contract uses inline assembly or CREATE2.
Cross-chain bridge vulnerabilities for LayerZero V2, Chainlink CCIP, Wormhole, Across, and general bridge security. Covers message ordering, fee handling, relayer trust, dust/normalization, and configuration pitfalls. Load when auditing any cross-chain protocol.
Chain-specific EVM quirks for Arbitrum, Optimism, Base, zkSync, Blast, BNB, Berachain and other L2s. Covers block.number behavior, sequencer downtime, address aliasing, retryable tickets, opcode differences, gas fee variations, and PUSH0 support. Load when deploying to any non-mainnet EVM chain.
