Fireblocks Wallet Extension Setup and Recovery Process for DApp Access
Install the browser add-on directly from the Chrome Web Store or Firefox Add-ons marketplace; verify the publisher’s authenticity before initiating the installation process. This component serves as your primary gateway, transforming the browser into a secure terminal for managing digital assets and interacting with decentralized applications.
Configuration requires linking the add-on to your institutional custody account. You will need your organization’s credentials and multi-party computation (MPC) quorum approval to authorize the connection. Establish specific transaction policies–defining approvers, asset types, and transfer limits–directly within your administrative console before the first transaction attempt.
Should you encounter access issues, the restoration procedure is initiated from your main platform dashboard. Navigate to the device management section and select the option to reinstate browser connectivity. This action generates a new, unique cryptographic key share, rendering any previously compromised or lost local data completely useless for authorization.
For reconnecting to external finance applications, manually re-approve each platform. Visit the application, select the custodied vault option at login, and confirm the new connection request through your standard policy workflow. Each application maintains a separate authorization record for enhanced security isolation.
FAQ:
I installed the Fireblocks browser extension but it’s asking for a “Recovery File” or “Manual Recovery”. Where do I get this?
You get the Recovery File only from your organization’s Fireblocks Administrator. This is a core security feature. The extension itself cannot create a new wallet; it can only recover access to an existing one configured in your company’s Fireblocks Console. If you are setting up for the first time, contact your internal admin team. They will generate and provide you with a secure Recovery File (a .txt file) or give you the details for Manual Recovery (a set of encrypted key shares). You cannot proceed without this information from your administrator.
Can I use the Fireblocks extension to connect to any dApp, like Uniswap or OpenSea?
Yes, the extension is designed to work with dApps that support WalletConnect or injected Web3 providers (like MetaMask). When you visit a supported dApp and click “Connect Wallet,” you should see an option for WalletConnect. Selecting it will typically show a QR code. Click the Fireblocks extension icon in your browser toolbar, go to the “WalletConnect” section, and scan that QR code to establish a secure connection. The dApp will then see your Fireblocks-managed wallet addresses for transactions.
What’s the difference between “Recovery File” and “Manual Recovery” during setup?
The Recovery File method is simpler and faster. Your administrator provides a single encrypted .txt file. During extension setup, you upload this file and then authenticate with your known password to decrypt it. Manual Recovery is used if you cannot use the file. It requires your administrator to give you three separate pieces of data: your encrypted private key shares. You must enter each one manually along with their corresponding share passwords. Both methods achieve the same result—reconstructing your wallet access within the extension—but the file method reduces input error.
Is my private key stored on my computer after I set up the Fireblocks extension?
No. A core principle of Fireblocks is that a complete private key is never assembled or stored on your browser or device. The extension holds only encrypted, partial key shares. For any transaction, these shares are combined temporarily using your password and then sent separately to the Fireblocks Wallet seed phrase network for approval based on your company’s policy (which may require other co-signers). After signing, the shares are immediately re-encrypted. Your local browser storage only contains these encrypted components, not a usable private key.
I installed the Fireblocks browser extension, but my existing wallets aren’t showing up. How do I recover or connect my previous Fireblocks account?
This is a common situation. The extension itself is a new interface, but it needs to be connected to your existing Fireblocks infrastructure. You cannot simply log in with an email and password. To see your wallets, you must first add the extension as a “Connectivity Method” to your existing Fireblocks Workspace. This is done by an Administrator of your Fireblocks account. They need to log into the Fireblocks web console, go to Settings -> Connectivity Methods, and add the browser extension. Once they approve it and provide you with a specific setup code, you can enter that code within the extension pop-up. This will link the extension to your account, and your vaults and wallets should then appear.
Can I use the Fireblocks extension to interact with any dapp, and what happens if a transaction fails?
Yes, the extension is designed to work with dapps that support WalletConnect or direct Ethereum provider injection (like MetaMask). When you visit a dapp, the extension should prompt you to connect. If a transaction fails after you approve it in Fireblocks, the outcome depends on the failure reason. A blockchain error (like insufficient gas or a contract revert) means the transaction simply won’t confirm on-chain, and no funds are moved. However, the transaction proposal inside your Fireblocks workspace will likely remain in a “Failed” or “Rejected” state. You or an approver will need to clear this proposal from the queue. The extension doesn’t automatically retry. You should check the transaction hash (if one was generated) on a block explorer and review the error in the Fireblocks console to understand the cause before trying again.
Is my private key stored in the Fireblocks browser extension?
No. A core security principle of Fireblocks is that private keys are never exposed. The extension does not hold or have access to your private keys. It acts as a secure bridge. When you initiate a transaction on a dapp, the extension creates a transaction proposal and sends it to your Fireblocks MPC (Multi-Party Computation) vault. The actual signing happens in the isolated, secure environment of the Fireblocks network using distributed key shares. The extension then relays the signed transaction back to the blockchain. Your keys remain protected within Fireblocks’ infrastructure at all times.
