Any wallet in the world could steal this entire crypto project with one function call ⚠️

We built Cornerstone to test our Smart Contract Auditor's limits: tokenized real estate, on-chain rent, a portfolio in Manhattan, London, and Sydney.

The kind of project that looks credible enough to attract real money. Then we ran the contract.

10 vulnerabilities. Here's the breakdown:

🔴 1 Critical 🟠 4 High 🟡 2 Medium 🟢 2 Low 🔵 1 Info

Here's what actually matters:

The Critical: setOwner() had zero access control. No require(msg.sender == owner). Nothing.

Any wallet, anywhere, could call it and take full ownership. From there you control minting, blacklisting, sell permissions, tax rates, and the ability to drain all ETH. Complete takeover. No exploit needed. Just a function call.

The 4 High findings:

1. claimRent() had a classic reentrancy bug. ETH gets sent to msg.sender before the claimable balance is zeroed out. A malicious contract can re-enter and loop until the contract is empty. Same pattern that drained The DAO in 2016. Still showing up in 2026.

2. setSellTax() had no upper bound. Fee is calculated as (amount * sellTax) / 100. Set sellTax to 100 and the fee equals the entire transfer amount. Owner can change this silently after launch.

3. The _transfer() function was a honeypot. Only addresses with canSell[address] = true can transfer to the liquidity pair. Constructor sets that to true for the deployer only. Every buyer is permanently blocked from selling unless manually whitelisted.

4. mint() had no supply cap. 100M fixed supply on the website. Unlimited minting in the contract.

All of it caught in minutes. Full report, severity ratings, exact code locations, remediation steps for every single finding.

The kind of output a traditional firm charges $20,000 to $50,000 and 3 to 4 weeks for.

Most projects that go live unaudited aren't rugpulls. They're just unlucky. This is what they're missing.

Our Smart Contract Auditor gives every project access to the kind of security review that used to be reserved for teams with serious budgets.

Upload any contract and it gives you a full report in seconds: every vulnerability ranked by severity, the exact line of code causing it, and a remediation step for each one.

No waiting weeks. No $20,000 invoice. The same depth of analysis, done in a fraction of the time.
