INSIDE LOOK: MY RECENT CERTIK AUDIT EXPERIENCE

To demonstrate expertise, here's a detailed breakdown of my recent Security Token audit — 1,100 lines of ERC-1400 code, 29 findings, $10.5K total cost.

The Numbers
- Total findings: 29
- Resolved in code: 13 (45%)
- Acknowledged with justification: 16 (55%)
- Original quote: $16,000 → Negotiated: $10,500

Critical Finding: Compliance Bypass

Most serious issue found. The controllerTransfer() function — required by ERC-1400 for regulatory compliance — didn't verify recipient whitelist status.

Code:

// VULNERABLE CODE:
function controllerTransfer(
    address from, 
    address to, 
    uint256 value
) public onlyRole(CONTROLLER_ROLE) {
    if (balanceOf[from] < value) revert TransferInsufficientBalance();
    // NO COMPLIANCE CHECKS - could transfer to non-KYC address!
    _performTransfer(from, to, value);
}

// FIXED CODE:
function controllerTransfer(
    address from, 
    address to, 
    uint256 value
) public onlyRole(CONTROLLER_ROLE) {
    if (!whitelistedAccounts.contains(to)) 
        revert RecipientNotWhitelisted();
    if (frozen[from] || frozen[to]) 
        revert AccountFrozen();
    if (balanceOf[from] < value) 
        revert TransferInsufficientBalance();
        
    _performTransfer(from, to, value);
    emit ControllerTransfer(msg.sender, from, to, value);
}

For Security Tokens this is Critical — AML violation, sanctions bypass, regulatory consequences.

High Finding: Race Condition in Batch Processing

Dividend batch system had race condition — new distribution call mid-batch reset index, losing progress.

Code:

// FIX — added lock:
bool public batchProcessingInProgress;

modifier noBatchInProgress() {
    if (batchProcessingInProgress) revert BatchProcessingInProgress();
    _;
}

What CertiK Checks vs. Misses

In scope: Code logic, known vulnerability patterns, basic economic attacks
Out of scope: Key management, operational security, team intentions

90% of "hacks" on audited projects are key compromises, not code bugs:
- Gala Games $216M (2024) — admin key stolen
- WazirX $234M (2024) — signing interface manipulation
- Merlin DEX $1.82M (2023) — rug pull via flagged emergencyWithdraw()

Audit finds centralization risks but cannot predict malicious intent.

Real Pricing

| Complexity | Base Quote | After Negotiation |
| ERC-20 (200-500 LOC) | $8-10K | $6-8K |
| NFT (500-1000 LOC) | $12-15K | ~$10K |
| Security Token (1000-1500 LOC) | $16-20K | $10-12K |
| DeFi Protocol (2000-5000 LOC) | $25-50K | Case by case |

As CertiK partner, I help clients get better rates and priority scheduling.

Security note for teams preparing to launch:

Most critical losses I see are not caused by obvious bugs,
but by:
– privileged functions (emergencyWithdraw, agents, controllers),
– missing post-operation invariants,
– edge cases in complex logic (health factor, liquidation paths),
– assumptions about external contracts and callbacks.

This is exactly what a pre-audit security review is meant to catch
before funds go live or before an external audit.

If you’re close to deployment or already have audit findings,
a focused security pass can save time, money, and risk.
