Fire is a free extension that simulates web3 transactions, showing you exactly what will enter and exit your wallet before you sign the contract. Currently supports ETH, POLYGON, OPTIMISM and arbitrum. Extension available for Chrome, Firefox and Brave Browsers. Fire Extension does not require wallet private information- no secret phrase. The Fire extension catches signature requests from your browser, runs a simulation, and then sends a pop up that shows you the results. If everything looks good, you sign the transaction using your wallet.   It does not log / store any transaction information.
