Analyzes token implementations for ERC20/ERC721 conformity, checks for 20+ weird token patterns, assesses contract composition and owner privileges, performs on-chain scarcity analysis, and evaluates how protocols handle non-standard tokens. Context-aware for both token implementations and token integrations.\n---\n\n# Token Integration Analyzer\n\n## Purpose\n\nSystematically analyzes the codebase for token-related security concerns using Trail of Bits' token integration checklist:\n\n1. **Token Implementations**: Analyze if your token follows ERC20/ERC721 standards or has non-standard behavior\n2. **Token Integrations**: Analyze how your protocol handles arbitrary tokens, including weird/non-standard tokens\n3. **On-chain Analysis**: Query deployed contracts for scarcity, distribution, and configuration\n4. **Security Assessment**: Identify risks from 20+ known weird token patterns\n\n**Framework**: Building Secure Contracts - Token Integration Checklist + Weird ERC20 Database\n\n---\n\n## How This Works\n\n### Phase 1: Context Discovery\nDetermines analysis context:\n- **Token implementation**: Are you building a token contract?\n- **Token integration**: Does your protocol interact with external tokens?\n- **Platform**: Ethereum, other EVM chains, or different platform?\n- **Token types**: ERC20, ERC721, or both?\n\n### Phase 2: Slither Analysis (if Solidity)\nFor Solidity projects, I'll help run:\n- `slither-check-erc` - ERC conformity checks\n- `slither --print human-summary` - Complexity and upgrade analysis\n- `slither --print contract-summary` - Function analysis\n- `slither-prop` - Property generation for testing\n\n### Phase 3: Code Analysis\nAnalyzes:\n- Contract composition and complexity\n- Owner privileges and centralization risks\n- ERC20/ERC721 conformity\n- Known weird token patterns\n- Integration safety patterns\n\n### Phase 4: On-chain Analysis (if deployed)\nIf you provide a contract address, I'll query:\n- Token scarcity and distribution\n- Total supply and holder concentration\n- Exchange listings\n- On-chain configuration\n\n### Phase 5: Risk Assessment\nProvides:\n- Identified vulnerabilities\n- Non-standard behaviors\n- Integration risks\n- Prioritized recommendations\n\n---\n\n## Assessment Categories\n\nI check 10 comprehensive categories covering all aspects of token security. For detailed criteria, patterns, and checklists, see [ASSESSMENT_CATEGORIES.md](resources/ASSESSMENT_CATEGORIES.md).\n\n### Quick Reference:\n\n1. **General Considerations** - Security reviews, team transparency, security contacts\n2. **Contract Composition** - Complexity analysis, SafeMath usage, function count, entry points\n3. **Owner Privileges** - Upgradeability, minting, pausability, blacklisting, team accountability\n4. **ERC20 Conformity** - Return values, metadata, decimals, race conditions, Slither checks\n5. **ERC20 Extension Risks** - External calls/hooks, transfer fees, rebasing/yield-bearing tokens\n6. **Token Scarcity Analysis** - Supply distribution, holder concentration, exchange distribution, flash loan/mint risks\n7. **Weird ERC20 Patterns** (24 patterns including):\n   - Reentrant calls (ERC777 hooks)\n   - Missing return values (USDT, BNB, OMG)\n   - Fee on transfer (STA, PAXG)\n   - Balance modifications outside transfers (Ampleforth, Compound)\n   - Upgradable tokens (USDC, USDT)\n   - Flash mintable (DAI)\n   - Blocklists (USDC, USDT)\n   - Pausable tokens (BNB, ZIL)\n   - Approval race protections (USDT, KNC)\n   - Revert on approval/transfer to zero address\n   - Revert on zero value approvals/transfers\n   - Multiple token addresses\n   - Low decimals (USDC: 6, Gemini: 2)\n   - High decimals (YAM-V2: 24)\n   - transferFrom with src == msg.sender\n   - Non-string metadata (MKR)\n   - No revert on failure (ZRX, EURS)\n   - Revert on large approvals (UNI, COMP)\n   - Code injection via token name\n   - Unusual permit function (DAI, RAI, GLM)\n   - Transfer less than amount (cUSDCv3)\n   - ERC-20 native currency representation (Celo, Polygon, zkSync)\n   - [And more...](resources/ASSESSMENT_CATEGORIES.md#7-weird-erc20-patterns)\n8. **Token Integration Safety** - Safe transfer patterns, balance verification, allowlists, wrappers, defensive patterns\n9. **ERC721 Conformity** - Transfer to 0x0, safeTransferFrom, metadata, ownerOf, approval clearing, token ID immutability\n10. **ERC721 Common Risks** - onERC721Received reentrancy, safe minting, burning approval clearing\n\n---\n\n## Example Output\n\nWhen analysis is complete, you'll receive a comprehensive report structured as follows:\n\n```\n=== TOKEN INTEGRATION ANALYSIS REPORT ===\n\nProject: MultiToken DEX\nToken Analyzed: Custom Reward Token + Integration Safety\nPlatform: Solidity 0.8.20\nAnalysis Date: March 15, 2024\n\n---\n\n## EXECUTIVE SUMMARY\n\nToken Type: ERC20 Implementation + Protocol Integrating External Tokens\nOverall Risk Level: MEDIUM\nCritical Issues: 2\nHigh Issues: 3\nMedium Issues: 4\n\n**Top Concerns:**\n⚠ Fee-on-transfer tokens not handled correctly\n⚠ No validation for missing return values (USDT compatibility)\n⚠ Owner can mint unlimited tokens without cap\n\n**Recommendation:** Address critical/high issues before mainnet launch.\n\n---\n\n## 1. GENERAL CONSIDERATIONS\n\n✓ Contract audited by CertiK (June 2023)\n✓ Team contactable via security@project.com\n✗ No security mailing list for critical announcements\n\n**Risk:** Users won't be notified of critical issues\n**Action:** Set up security@project.com mailing list\n\n---\n\n## 2. CONTRACT COMPOSITION\n\n### Complexity Analysis\n\n**Slither human-summary Results:**\n- 456 lines of code\n- Cyclomatic complexity: Average 6, Max 14 (transferWithFee())\n- 12 functions, 8 state variables\n- Inheritance depth: 3 (moderate)\n\n✓ Contract complexity is reasonable\n⚠ transferWithFee() complexity high (14) - consider splitting\n\n### SafeMath Usage\n\n✓ Using Solidity 0.8.20 (built-in overflow protection)\n✓ No unchecked blocks found\n✓ All arithmetic operations protected\n\n### Non-Token Functions\n\n**Functions Beyond ERC20:**\n- setFeeCollector() - Admin function ✓\n- setTransferFee() - Admin function ✓\n- withdrawFees() - Admin function ✓\n- pause()/unpause() - Emergency functions ✓\n\n⚠ 4 non-token functions (acceptable but adds complexity)\n\n### Address Entry Points\n\n✓ Single contract address\n✓ No proxy with multiple entry points\n✓ No token migration creating address confusion\n\n**Status:** PASS\n\n---\n\n## 3. OWNER PRIVILEGES\n\n### Upgradeability\n\n⚠ Contract uses TransparentUpgradeableProxy\n**Risk:** Owner can change contract logic at any time\n\n**Current Implementation:**\n- ProxyAdmin: 0x1234... (2/3 multisig) ✓\n- Timelock: None ✗\n\n**Recommendation:** Add 48-hour timelock to all upgrades\n\n### Minting Capabilities\n\n❌ CRITICAL: Unlimited minting\nFile: contracts/RewardToken.sol:89\n```solidity\nfunction mint(address to, uint256 amount) external onlyOwner {\n    _mint(to, amount);  // No cap!\n}\n```\n\n**Risk:** Owner can inflate supply arbitrarily\n**Fix:** Add maximum supply cap or rate-limited minting\n\n### Pausability\n\n✓ Pausable pattern implemented (OpenZeppelin)\n✓ Only owner can pause\n⚠ Paused state affects all transfers (including existing holders)\n\n**Risk:** Owner can trap all user funds\n**Mitigation:** Use multi-sig for pause function (already implemented ✓)\n\n### Blacklisting\n\n✗ No blacklist functionality\n**Assessment:** Good - no centralized censorship risk\n\n### Team Transparency\n\n✓ Team members public (team.md)\n✓ Company registered in Switzerland\n✓ Accountable and contactable\n\n**Status:** ACCEPTABLE\n\n---\n\n## 4. ERC20 CONFORMITY\n\n### Slither-check-erc Results\n\nCommand: slither-check-erc . RewardToken --erc erc20\n\n✓ transfer returns bool\n✓ transferFrom returns bool\n✓ name, decimals, symbol present\n✓ decimals returns uint8 (value: 18)\n✓ Race condition mitigated (increaseAllowance/decreaseAllowance)\n\n**Status:** FULLY COMPLIANT\n\n### slither-prop Test Results\n\nCommand: slither-prop . --contract RewardToken\n\n**Generated 12 properties, all passed:**\n✓ Transfer doesn't change total supply\n✓ Allowance correctly updates\n✓ Balance updates match transfer amounts\n✓ No balance manipulation possible\n[... 8 more properties ...]\n\n**Echidna fuzzing:** 50,000 runs, no violations ✓\n\n**Status:** EXCELLENT\n\n---\n\n## 5. WEIRD TOKEN PATTERN ANALYSIS\n\n### Integration Safety Check\n\n**Your Protocol Integrates 5 External Tokens:**\n1. USDT (0xdac17f9...)\n2. USDC (0xa0b86991...)\n3. DAI (0x6b175474...)\n4. WETH (0xc02aaa39...)\n5. UNI (0x1f9840a8...)\n\n### Critical Issues Found\n\n❌ **Pattern 7.2: Missing Return Values**\n**Found in:** USDT integration\nFile: contracts/Vault.sol:156\n```solidity\nIERC20(usdt).transferFrom(msg.sender, address(this), amount);\n// No return value check! USDT doesn't return bool\n```\n\n**Risk:** Silent failures on USDT transfers\n**Exploit:** User appears to deposit, but no tokens moved\n**Fix:** Use OpenZeppelin SafeERC20 wrapper\n\n---\n\n❌ **Pattern 7.3: Fee on Transfer**\n**Risk for:** Any token with transfer fees\nFile: contracts/Vault.sol:170\n```solidity\nuint256 balanceBefore = IERC20(token).balanceOf(address(this));\ntoken.transferFrom(msg.sender, address(this), amount);\nshares = amount * exchangeRate;  // WRONG! Should use actual received amount\n```\n\n**Risk:** Accounting mismatch if token takes fees\n**Exploit:** User credited more shares than tokens deposited\n**Fix:** Calculate shares from `balanceAfter - balanceBefore`\n\n---\n\n### Known Non-Standard Token Handling\n\n✓ **USDC:** Properly handled (SafeERC20, 6 decimals accounted for)\n⚠ **DAI:** permit() function not used (opportunity for gas savings)\n✗ **USDT:** Missing return value not handled (CRITICAL)\n✓ **WETH:** Standard wrapper, properly handled\n⚠ **UNI:** Large approval handling not checked (reverts >= 2^96)\n\n---\n\n[...
