Actually understand what you’re signing
With our UX, you can see in simple terms what a smart contract is actually doing.
How it works
It’s as easy as one, two, three.
Download the Fire extension.
The Fire extension catches signature requests from your browser, runs a simulation, and shows you the results.
If everything looks good, you sign the transaction using your wallet.

Questions?
We’ve got all the answers right here.
Do I have to give Fire my secret phrase?
No, we will never ask for your secret phrase!
Do I need to give Fire my wallet address?
No, we track Ethereum transactions in your browser and will send a pop up with your wallet of choice.
Can I sign transactions in the Fire extension?
No, we do not have access to whether you can sign or reject a transaction. Thus, we are displaying transactions from your Web3 wallet.
How do we know of malicious contracts you are about to sign?
We simulate the transaction before you sign in your wallet, scanning to see if you are transferring your wallet contents and getting nothing in return or setting approvals that you shouldn’t be!
What wallets does Fire work with?
Any Ethereum wallet works with Fire!
How much does Fire cost?
Fire is completely free!
