About the company

Fire provides a free browser extension that simulates Ethereum (ETH) transactions to show users a clear preview of what will enter and exit their wallets before signing any contract. This helps non-technical users understand the implications of their web3 actions and avoid scams. The extension works within the browser by intercepting transaction flows and presenting a transparent, human-readable preview of the transfer details, enabling safer wallet activity in web3. Unlike some competitors that may focus on on-chain analysis or in-depth tooling, Fire targets ease of use for a broad audience and aims to build trust through safety and clarity. The company could monetize via premium features, partnerships with other blockchain services, or advanced analytics and support, operating on a freemium model. Fire’s goal is to enhance security and transparency in web3 transactions for ETH wallet users, from casual users to active traders.
