What Pocket Universe does
Pocket Universe is a browser extension operated by Kerberus Cyber Security, Inc., a Delaware-incorporated cybersecurity company headquartered in San Francisco. Founded in 2022 by Danor Cohen (CTO, formerly Head of Offensive Security at Salesforce, with 15 years of security expertise and recognition as a Top-10 PayPal bug hunter) and Alex Katz (CEO, with operational and global marketing experience in financial markets), the company builds a single-product consumer security tool that protects Web3 users from malicious transaction signatures.
The core product is a browser extension available on Chrome, Firefox, Brave, and Edge that intercepts and simulates cryptocurrency transactions before they are signed in a user's wallet. It surfaces warnings on malicious signatures, shows which assets will move during signing, flags serial rugpullers on NFT marketplaces such as OpenSea and Blur, and notifies users when previously-used protocols are exploited (with deep links to Revoke.cash for revoking approvals). The company reports 200,000+ users, $1B+ in assets protected, and 3M+ transactions analyzed per week.
The business model is product-led growth via the Chrome Web Store and Firefox Add-ons, supplemented by community-driven engagement on Discord and Twitter/X. The base extension is free; a premium layer offers up to $30,000 per-transaction financial protection paid in USDC, priced at a 0.8% fee on certain DeFi transactions and underwritten by a third-party coverage provider. Claims are subject to a 21-day filing window and KYC verification. The company is privately held, with no disclosed institutional investors in attributed sources, and serves individual retail crypto users as its sole customer segment.

Pocket Universe competitors and assessment
Company assessmentDirect peers
- Blowfish: Provides Web3 transaction simulation and scam-detection APIs for wallets and dapps, directly competing with Pocket Universe's core simulation engine. Both target the same problem of warning users before they sign malicious on-chain transactions.
- Web3 Antivirus: Browser-based security extension that flags scam transactions, phishing sites, and malicious contracts before signing. Competes head-to-head with Pocket Universe in the same Chrome/Firefox extension distribution model.
- Wallet Guard: Browser extension focused on Web3 phishing and wallet-drainer detection, with transaction simulation features. Targets the same retail Web3 user base and competes for the same Chrome Web Store distribution.
- Stelo Labs: Built a transaction simulation and scam-detection product (now integrated into Phantom wallet). Competes with Pocket Universe's simulation technology and represents the native-wallet competitive threat.
- Scam Sniffer: Web3 anti-phishing and wallet-drainer detection service with browser-based warnings and analytics. Targets overlapping scams (phishing signatures, drainers) using similar detection methodologies.
- Harpie: Real-time wallet protection layer that blocks malicious transactions before they confirm and offers recovery tooling. Directly comparable prevention-first value proposition to Pocket Universe.
- Revoke.cash: Token-approval management tool that helps users revoke risky smart-contract permissions; Pocket Universe links users to Revoke.cash after exploit detections. Comparable on the approval/revocation dimension of wallet security.
Broad incumbents
- MetaMask (Consensys): Largest self-custodial Web3 wallet with the user relationship and distribution to embed native scam-warning and simulation features. Represents the most significant incumbent threat to third-party browser extensions like Pocket Universe.
- Phantom: Leading multi-chain wallet (having absorbed Stelo Labs) that integrates native transaction simulation and security features. Sets the baseline user expectation for built-in wallet protection.
- Trust Wallet: Major multi-chain wallet (Binance-affiliated) serving tens of millions of users; could ship native security features that compete with Pocket Universe's extension-based protection.
