At Fire, we believe everyone should know what they're agreeing to BEFORE they sign a smart contract - yet very few actually do. We’d never sign a contract in real life without understanding it first. Yet, so many users transfer hundreds of thousands of $$ without any idea of what they’re actually agreeing to.

So… we built Fire.

Fire is a Chrome extension that sits in your browser and simulates a transaction before you sign with your wallet, giving you visibility into exactly what you're signing. We work with your current wallet and do not have access to your private key (and will never ask for it).

With Fire, you can preview what will enter and exit your wallet BEFORE you sign a transaction.

How it Works: After downloading the Fire extension, it will catch signature requests from your browser, run a simulation, and show you the results. If everything looks good, you sign the transaction using your wallet.

Privacy and Security: We at Fire are committed to protecting your privacy. The information we gather or process is used solely for core functionality of Fire and to improve the quality and security of our service. Your information isn’t and has never been sold to third parties. For more information on privacy and the security of your data visit

The Fire extension can’t control any of your funds since we do not have access to your seed phrase (and we will never ask for it).
