Security dApps are tools and marketplaces that help find weaknesses in smart contracts and warn users about risky tokens. The category covers two groups. One serves developers and protocols, with audits, contests and bug bounties. The other serves traders, with scanners that check a contract before money goes in. Our list has four entries: Sherlock, Hats.V2, Quillcheck and Quick Intel.
The business models differ by group. Sherlock sells security services such as audits, contests, AI review and bounties to onchain teams. Hats.V2 runs a permissionless marketplace where projects fund bounties and audit competitions, and researchers and liquidity providers take part. Scanners like Quillcheck and Quick Intel simulate trades or analyse contract code to flag honeypots, high taxes and other scam signs. Revenue models for the scanners are not set out in our data, so check each tool's own site for details.
When comparing, start with who the tool is for: a project team that wants a review, or a trader who wants a quick check. Then look at chain support, since Hats.V2 spans five networks while Quillcheck is on Base and Quick Intel covers Base and Ethereum. Also weigh how clearly each tool explains its method and its limits. No scan or audit removes risk, so use these tools as one layer of checking. If your trading involves gambling, you must be 18+ (21+ where required) and confirm that online gambling is legal where you live.}

Frequently asked questions
What is a crypto security dApp?
A security dApp helps protect people or projects from smart contract flaws, scams and exploits. Some, like Sherlock and Hats.V2, serve protocol teams through audits, contests and bug bounties. Others, like Quillcheck and Quick Intel, are scanners that help everyday traders check a token before buying.
Can a token scanner guarantee a token is safe?
No. A scanner reads a contract and may simulate a trade to flag known warning signs such as honeypots or high taxes. It cannot predict every rug pull, a hidden admin function or a price collapse. Treat the result as one input and not as a guarantee of safety.
Which tools help check a token before I buy?
Quillcheck and Quick Intel are both aimed at users who want to check a token before trading. Quillcheck focuses on simulating trades and flagging honeypots and high taxes on Base. Quick Intel uses AI-assisted contract analysis and covers Base and Ethereum on our list.
How do Sherlock and Hats.V2 differ from scanners?
Sherlock sells audits, contests, AI review and bug bounty services to onchain teams. Hats.V2 is an open marketplace where projects can post bounties and audit competitions that security researchers can join. Both are mainly built for developers and project teams, not casual traders.
Does an audit mean a protocol is safe to use?
Not necessarily. Audits, contests and bounties lower the chance of undiscovered bugs but cannot remove it. Check what was reviewed, when, whether the code has changed since, and whether any findings were left unresolved.
Are there age or legal limits when using these tools?
The scanners on our list are checking tools, not gambling products, so there is no age rule for the tools themselves. If you use them before trading tokens or visiting crypto casinos, you must be 18 or older (21 or older in some places). Check that online gambling is legal where you live.
