Use this when you need a fast first-pass review of a DeFi protocol or smart contract scope before committing hours to a manual audit. ## Search Keywords / Best Use Cases - paid security skill pack - smart contract audit workflow - smart contract audit checklist - smart contract audit template - smart contract security checklist - smart contract audit report template - DeFi audit workflow - DeFi audit template - DeFi security checklist - Solidity security checklist - Solidity audit report template - EVM audit checklist - paid smart contract audit pack - Atlas smart contract audit pack - Atlas security skill pack - Solidity audit template - DeFi audit checklist - bug bounty report template - Code4rena audit prep - Sherlock audit prep - HackenProof bounty workflow - smart contract audit - smart contract auditor - DeFi audit - DeFi security audit - Solidity audit - Solidity auditor - EVM audit - vulnerability scanner - vulnerability assessment - smart contract vulnerability triage - smart contract scanner - bug bounty triage - bug bounty automation - Code4rena audit workflow - Code4Arena warden - Sherlock audit workflow - HackenProof bounty workflow - access control review - oracle manipulation review - oracle manipulation attack - reentrancy checklist - reentrancy vulnerability - upgradeable proxy review - DeFi protocol security - smart contract security audit - blockchain security audit - Solidity vulnerability scanner - EVM vulnerability assessment - audit checklist - security audit report - vulnerability report - DeFi audit report - code review checklist - attack surface mapping - protocol audit - audit automation ## When to Use - New smart contract audit target assigned - DeFi contest just opened and you need to prioritize files - Bug bounty scope includes Solidity/EVM contracts - You need a structured first-pass vulnerability checklist - You want to map attack surface before deep manual review ## What It Produces A structured markdown audit triage report with: - Target overview - Protocol type and contract categories - Attack surface map - High-priority vulnerability classes - Contract-by-contract checklist - Recommended deep-dive order - Quick-win review items ## Workflow ### Phase 1: Smart Contract Scope Mapping For each contract in scope: 1. Identify protocol type: lending, AMM, vault, staking, bridge, oracle, governance, NFT, account abstraction 2. Identify external integrations: Chainlink, Uniswap, Curve, ERC20 tokens, bridges, routers, keepers 3. Flag proxy/upgrade patterns: `EIP1967`, `UUPS`, transparent proxy, beacon proxy, clones 4. Identify privileged roles: owner, admin, guardian, pauser, timelock, operator 5. Note novel or high-risk mechanisms: custom accounting, share pricing, liquidation math, rewards, TWAPs ### Phase 2: DeFi Vulnerability Prioritization Score each vulnerability class by **likelihood × impact**: ```text HIGH PRIORITY - Reentrancy: external calls + state changes + callbacks - Access control: missing modifiers, wrong role assumptions, admin bypass - Oracle manipulation: stale price, TWAP manipulation, decimal mismatch, fallback oracle bugs - Accounting bugs: share price drift, rounding loss, fee math, collateral/debt mismatch - Liquidation bugs: bad health factor math, stale collateral values, griefable liquidation paths - Upgradeability bugs: unprotected initializer, storage collision, implementation takeover MEDIUM PRIORITY - Fee-on-transfer / rebasing token edge cases - ERC777 / callback-enabled token surprises - Sandwich / MEV-sensitive pricing - DOS via unbounded loops or griefable state - Signature replay / permit domain separator issues LOW PRIORITY BUT CHECK - Input validation gaps - Event/reporting mismatch - Gas griefing - Minor precision loss without exploitable value extraction ``` ### Phase 3: Contract-by-Contract Checklist ```markdown ## Contract: ### External Calls / Reentrancy - [ ] External calls happen after state updates? - [ ] Reentrancy guard exists where callbacks are possible? - [ ] ERC777 / ERC721 receiver / flash loan callbacks considered? ### Access Control - [ ] Privileged functions use correct modifier? - [ ] Timelock/owner/admin boundaries are clear? - [ ] Emergency functions cannot steal user funds? ### Oracle / Pricing - [ ] Oracle freshness checked? - [ ] Decimal normalization correct? - [ ] Fallback oracle cannot be manipulated? - [ ] TWAP window long enough for protocol value at risk? ### Accounting - [ ] Shares/assets conversion handles rounding direction correctly? - [ ] Fee calculations cannot drain or brick accounting? - [ ] Deposits/withdrawals preserve invariants? ### Upgradeability - [ ] Initializers protected? - [ ] Storage layout compatible? - [ ] Implementation cannot be selfdestructed or hijacked? ``` ### Phase 4: Audit Triage Report ```markdown # Smart Contract Audit Triage: ## Target Overview - Protocol type: - Chain(s): - Contracts in scope: - Highest-value assets: ## Attack Surface Summary - External integrations: - Oracle dependencies: - Upgrade pattern: - Privileged roles: ## Top Vulnerability Classes to Review 1. [HIGH] — 2. [HIGH] — 3. [MEDIUM] — ## Recommended Deep-Dive Order 1. — focus on 2. — focus on 3. — focus on ## Quick Wins Checklist - [ ] Reentrancy review - [ ] Access control review - [ ] Oracle manipulation review - [ ] Upgradeability review - [ ] Accounting invariant review --- Generated by Atlas Smart Contract Auditor.
