AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
The Token Integration Analyzer provides a systematic security review for smart contract tokens and protocols that interact with them. It leverages the Trail of Bits token integration checklist to evaluate codebases for ERC20/ERC721 standard conformity, identify risks from over 20 non-standard 'weird' token patterns, and assess contract composition, owner privileges, and integration safety. The tool supports both static analysis of Solidity code and on-chain analysis of deployed contracts to ensure robust handling of external token interactions.
What it does
- Performs automated ERC20/ERC721 conformity checks using static analysis tools.
- Identifies risks from 20+ known weird token patterns like fee-on-transfer or missing return values.
- Evaluates contract composition, complexity, and owner privilege centralization.
- Analyzes on-chain data for token scarcity, holder concentration, and configuration.
- Provides a structured security report with prioritized remediation recommendations.
- Validates integration safety patterns for protocols interacting with external tokens.
When to use it
- When developing or auditing a new ERC20 or ERC721 token implementation.
- Before integrating external tokens into a DeFi protocol or smart contract system.
- When assessing the risk profile of arbitrary tokens accepted by a platform.
- To verify that a protocol correctly handles non-standard token behaviors.
Advantages
- Reduces risks associated with non-standard token behaviors in smart contract integrations.
- Provides a comprehensive, standardized checklist based on industry-recognized security practices.
- Combines static code analysis with on-chain data for a holistic security view.
- Helps developers identify and fix critical vulnerabilities before mainnet deployment.
Usage examples
- “Analyze my ERC20 token implementation for potential security risks and standard conformity.”
- The agent will review the provided Solidity code, run conformity checks, identify any non-standard patterns, and provide a report on potential vulnerabilities.
- “I am integrating USDT into my vault. What should I check for?”
- The agent will analyze the integration code, specifically checking for missing return value handling and other known USDT-specific quirks.
- “Assess the risks of this deployed token contract at address 0x123...”
- The agent will perform an on-chain analysis of the contract, checking for holder concentration, owner privileges, and configuration risks.

Documentation by Trail of Bits
Token Integration Analyzer
Purpose
Systematically analyzes the codebase for token-related security concerns using Trail of Bits' token integration checklist:
Token Implementations: Analyze if your token follows ERC20/ERC721 standards or has non-standard behavior
Token Integrations: Analyze how your protocol handles arbitrary tokens, including weird/non-standard tokens
On-chain Analysis: Query deployed contracts for scarcity, distribution, and configuration
Security Assessment: Identify risks from 20+ known weird token patterns
Framework: Building Secure Contracts - Token Integration Checklist + Weird ERC20 Database
How This Works
Phase 1: Context Discovery
Determines analysis context:
Token implementation: Are you building a token contract?
Token integration: Does your protocol interact with external tokens?
Platform: Ethereum, other EVM chains, or different platform?
Token types: ERC20, ERC721, or both?
Phase 2: Slither Analysis (if Solidity)
For Solidity projects, I'll help run:
slither-check-erc- ERC conformity checksslither --print human-summary- Complexity and upgrade analysisslither --print contract-summary- Function analysisslither-prop- Property generation for testing
Phase 3: Code Analysis
Analyzes:
Contract composition and complexity
Owner privileges and centralization risks
ERC20/ERC721 conformity
Known weird token patterns
Integration safety patterns
Phase 4: On-chain Analysis (if deployed)
If you provide a contract address, I'll query:
Token scarcity and distribution
Total supply and holder concentration
Exchange listings
On-chain configuration
Phase 5: Risk Assessment
Provides:
Identified vulnerabilities
Non-standard behaviors
Integration risks
Prioritized recommendations
Assessment Categories
I check 10 comprehensive categories covering all aspects of token security. For detailed criteria, patterns, and checklists, see ASSESSMENT_CATEGORIES.md.
Quick Reference:
General Considerations - Security reviews, team transparency, security contacts
Contract Composition - Complexity analysis, SafeMath usage, function count, entry points
Owner Privileges - Upgradeability, minting, pausability, blacklisting, team accountability
ERC20 Conformity - Return values, metadata, decimals, race conditions, Slither checks
ERC20 Extension Risks - External calls/hooks, transfer fees, rebasing/yield-bearing tokens
Token Scarcity Analysis - Supply distribution, holder concentration, exchange distribution, flash loan/mint risks
Weird ERC20 Patterns (24 patterns including):
Reentrant calls (ERC777 hooks)
Missing return values (USDT, BNB, OMG)
Fee on transfer (STA, PAXG)
Balance modifications outside transfers (Ampleforth, Compound)
Upgradable tokens (USDC, USDT)
Flash mintable (DAI)
Blocklists (USDC, USDT)
Pausable tokens (BNB, ZIL)
Approval race protections (USDT, KNC)
Revert on approval/transfer to zero address
Revert on zero value approvals/transfers
Multiple token addresses
Low decimals (USDC: 6, Gemini: 2)
High decimals (YAM-V2: 24)
transferFrom with src == msg.sender
Non-string metadata (MKR)
No revert on failure (ZRX, EURS)
Revert on large approvals (UNI, COMP)
Code injection via token name
Unusual permit function (DAI, RAI, GLM)
Transfer less than amount (cUSDCv3)
ERC-20 native currency representation (Celo, Polygon, zkSync)
Token Integration Safety - Safe transfer patterns, balance verification, allowlists, wrappers, defensive patterns
ERC721 Conformity - Transfer to 0x0, safeTransferFrom, metadata, ownerOf, approval clearing, token ID immutability
ERC721 Common Risks - onERC721Received reentrancy, safe minting, burning approval clearing
Example Output
When analysis is complete, you'll receive a comprehensive report structured as follows:

## EXECUTIVE SUMMARY
Token Type: ERC20 Implementation + Protocol Integrating External Tokens
Overall Risk Level: MEDIUM
Critical Issues: 2
High Issues: 3
Medium Issues: 4
**Top Concerns:**
⚠ Fee-on-transfer tokens not handled correctly
⚠ No validation for missing return values (USDT compatibility)
⚠ Owner can mint unlimited tokens without cap
**Recommendation:** Address critical/high issues before mainnet launch.
---
## 1. GENERAL CONSIDERATIONS
✓ Contract audited by CertiK (June 2023)
✓ Team contactable via [email protected]
✗ No security mailing list for critical announcements
**Risk:** Users won't be notified of critical issues
**Action:** Set up [email protected] mailing list
---
## 2. CONTRACT COMPOSITION
### Complexity Analysis
**Slither human-summary Results:**
- 456 lines of code
- Cyclomatic complexity: Average 6, Max 14 (transferWithFee())
- 12 functions, 8 state variables
- Inheritance depth: 3 (moderate)
✓ Contract complexity is reasonable
⚠ transferWithFee() complexity high (14) - consider splitting
### SafeMath Usage
✓ Using Solidity 0.8.20 (built-in overflow protection)
✓ No unchecked blocks found
✓ All arithmetic operations protected
### Non-Token Functions
**Functions Beyond ERC20:**
- setFeeCollector() - Admin function ✓
- setTransferFee() - Admin function ✓
- withdrawFees() - Admin function ✓
- pause()/unpause() - Emergency functions ✓
⚠ 4 non-token functions (acceptable but adds complexity)
### Address Entry Points
✓ Single contract address
✓ No proxy with multiple entry points
✓ No token migration creating address confusion
**Status:** PASS
---
## 3. OWNER PRIVILEGES
### Upgradeability
⚠ Contract uses TransparentUpgradeableProxy
**Risk:** Owner can change contract logic at any time
**Current Implementation:**
- ProxyAdmin: 0x1234... (2/3 multisig) ✓
- Timelock: None ✗
**Recommendation:** Add 48-hour timelock to all upgrades
### Minting Capabilities
❌ CRITICAL: Unlimited minting
File: contracts/RewardToken.sol:89
```solidity
function mint(address to, uint256 amount) external onlyOwner {
_mint(to, amount); // No cap!
}Risk: Owner can inflate supply arbitrarily Fix: Add maximum supply cap or rate-limited minting
Pausability
✓ Pausable pattern implemented (OpenZeppelin) ✓ Only owner can pause ⚠ Paused state affects all transfers (including existing holders)
Risk: Owner can trap all user funds Mitigation: Use multi-sig for pause function (already implemented ✓)
Blacklisting
✗ No blacklist functionality Assessment: Good - no centralized censorship risk
Team Transparency
✓ Team members public (team.md) ✓ Company registered in Switzerland ✓ Accountable and contactable
Status: ACCEPTABLE
4. ERC20 CONFORMITY
Slither-check-erc Results
Command: slither-check-erc . RewardToken --erc erc20
✓ transfer returns bool ✓ transferFrom returns bool ✓ name, decimals, symbol present ✓ decimals returns uint8 (value: 18) ✓ Race condition mitigated (increaseAllowance/decreaseAllowance)
Status: FULLY COMPLIANT
slither-prop Test Results
Command: slither-prop . --contract RewardToken
Generated 12 properties, all passed: ✓ Transfer doesn't change total supply ✓ Allowance correctly updates ✓ Balance updates match transfer amounts ✓ No balance manipulation possible [... 8 more properties ...]
Echidna fuzzing: 50,000 runs, no violations ✓
Status: EXCELLENT
5. WEIRD TOKEN PATTERN ANALYSIS
Integration Safety Check
Your Protocol Integrates 5 External Tokens:
USDT (0xdac17f9...)
USDC (0xa0b86991...)
DAI (0x6b175474...)
WETH (0xc02aaa39...)
UNI (0x1f9840a8...)
Critical Issues Found
❌ Pattern 7.2: Missing Return Values Found in: USDT integration File: contracts/Vault.sol:156
IERC20(usdt).transferFrom(msg.sender, address(this), amount);
// No return value check! USDT doesn't return boolRisk: Silent failures on USDT transfers Exploit: User appears to deposit, but no tokens moved Fix: Use OpenZeppelin SafeERC20 wrapper
❌ Pattern 7.3: Fee on Transfer Risk for: Any token with transfer fees File: contracts/Vault.sol:170
uint256 balanceBefore = IERC20(token).balanceOf(address(this));
token.transferFrom(msg.sender, address(this), amount);
shares = amount * exchangeRate; // WRONG! Should use actual received amountRisk: Accounting mismatch if token takes fees
Exploit: User credited more shares than tokens deposited
Fix: Calculate shares from balanceAfter - balanceBefore
Known Non-Standard Token Handling
✓ USDC: Properly handled (SafeERC20, 6 decimals accounted for) ⚠ DAI: permit() function not used (opportunity for gas savings) ✗ USDT: Missing return value not handled (CRITICAL) ✓ WETH: Standard wrapper, properly handled ⚠ UNI: Large approval handling not checked (reverts >= 2^96)
[... Additional sections for remaining analysis categories ...]

## Rationalizations (Do Not Skip)
| Rationalization | Why It's Wrong | Required Action |
|-----------------|----------------|-----------------|
| "Token looks standard, ERC20 checks pass" | 20+ weird token patterns exist beyond ERC20 compliance | Check ALL weird token patterns from database (missing return, revert on zero, hooks, etc.) |
| "Slither shows no issues, integration is safe" | Slither detects some patterns, misses integration logic | Complete manual analysis of all 5 token integration criteria |
| "No fee-on-transfer detected, skip that check" | Fee-on-transfer can be owner-controlled or conditional | Test all transfer scenarios, check for conditional fee logic |
| "Balance checks exist, handling is safe" | Balance checks alone don't protect against all weird tokens | Verify safe transfer wrappers, revert handling, approval patterns |
| "Token is deployed by reputable team, assume standard" | Reputation doesn't guarantee standard behavior | Analyze actual code and on-chain behavior, don't trust assumptions |
| "Integration uses OpenZeppelin, must be safe" | OpenZeppelin libraries don't protect against weird external tokens | Verify defensive patterns around all external token calls |
| "Can't run Slither, skipping automated analysis" | Slither provides critical ERC conformance checks | Manually verify all slither-check-erc criteria or document why blocked |
| "This pattern seems fine" | Intuition misses subtle token integration bugs | Systematically check all 20+ weird token patterns with code evidence |
---
## Deliverables
When analysis is complete, I'll provide:
1. **Compliance Checklist** - Checkboxes for all assessment categories
2. **Weird Token Pattern Analysis** - Presence/absence of all 24 patterns with risk levels and evidence
3. **On-chain Analysis Report** (if applicable) - Holder distribution, exchange listings, configuration
