In blockchain, where individuals hold custody of their own funds, they should also be in charge of their own security. OpenSentry brings audit logic to the wallet layer, shifting security from protocol teams to individual users.
OpenSentry is a public good.
Free and open for everyone.
Every blockchain interaction requires trusting code.
Today, only well-funded protocols get professional audits.
Individual users interact with all kinds of contracts without protection.
Behind the "Confirm Transaction" button may be exploit paths you don't understand.
Deep security audits for developers and teams are costly and time-consuming, and are not accessible to many projects.
Users are left to trust protocols to take care of their security, or use wallet protection services that rely on blacklists and reputation scores but don't analyze the code.
OpenSentry analyzes a contract like an auditor would, applying techniques that have so far been only available in professional audits.
After analysis, OpenSentry tells you in plain language
exactly what the issue is and what it means for your funds.
Beyond protecting individual users, OpenSentry creates ecosystem-wide security benefits. Projects that pass analysis can earn a certification badge — a revocable soulbound NFT and visual badge to display on your Dapp.
Establish a public, on-chain trust signal for the communities interacting with your contracts.
I am a blockchain developer and smart contract auditor working on security-critical systems. I review production contracts and analyze exploits for a living. I see firsthand how users are exposed to hidden risks that no wallet warns them about. OpenSentry is my answer to that gap.
My path to Web3 started through activism — a belief that decentralized systems can shift power to individuals. As I evolved into auditing, I realized the security expertise that protects protocols should be a public good, not a luxury.
Professional auditing is a long, intensive process that demands deep expertise — and not every project can afford it. I sometimes offer my services for free or near-free to projects I believe in, but that doesn't scale. OpenSentry is how I scale that protection to every user, for every protocol they interact with.
