Overview
Pocket Universe is a security-focused browser extension. Before you sign any transaction or message, it simulates the outcome and shows exactly which assets will leave and enter your wallet, alerting you to malicious contracts, fake NFT listings, fraudulent orders on DEXs, and signatures that steal funds. It works alongside your wallet (MetaMask and others) without taking custody of your assets—it’s an extra layer of protection against the most common day-to-day scams in Web3.
