Fireblocks wallet extension setup and dapp recovery guide



Fireblocks Wallet Extension Setup and DApp Recovery Steps for Secure Access

Install the browser add-on solely from the authorized Chrome Web Store or Firefox Add-ons portal to mitigate counterfeit software risks.

Initial Configuration & Security Protocol

Launch the installed add-on; you will not create new credentials. Instead, select the option to integrate with an existing institutional vault. This action triggers a QR code display.

QR Authentication & Device Policy

Using your organization's mobile administration application, scan the presented QR code. This step cryptographically links the browser tool to your corporate asset vault. Approval is mandated via your configured mobile authorization policy, typically requiring multiple user confirmations.


Define a distinctive nickname for this browser linkage (e.g., "Trading_Chrome_WS1"). This clarifies device audits within your platform's dashboard. Finalize the pairing within your mobile app.

Reconnecting to Decentralized Applications

If a web-based application loses its connection to your asset vault, follow this precise sequence.


Visit the application's website and initiate a transaction or connection request.
Your browser add-on should automatically activate, presenting a transaction pane. If it does not, click its icon in your browser's toolbar to wake it.
The transaction details will appear. Review the recipient address, network, and amount meticulously.
Submit the transaction for approval within the add-on interface. No transaction executes locally.

Authorization Workflow

The transaction now enters your organization's predefined governance pipeline. Access your mobile administration application. You will see a pending transaction requiring review. Assemble the necessary approvals according to your policy–this may involve several team members. Only after satisfying all policy rules will the operation be signed and broadcast to the network.


The web application will detect the broadcasted transaction, restoring its interface connection to your vault's active address.

Common Connectivity Resolutions

Add-on Not Detected: Ensure the plugin is pinned to your browser's toolbar. Refresh the web application page completely.
Stale Transaction Pane: Clear all pending actions from the add-on's interface and restart the process from the web app.
Policy Approval Halt: Verify all designated approvers are available and using the latest version of the mobile admin app. A single pending approval blocks execution.


Consistently update the browser add-on and mobile administration application to maintain compatibility with latest network standards and security patches.

Fireblocks Wallet Extension Setup and DApp Recovery Guide

Install the browser add-on exclusively from the official Chrome Web Store or Firefox Add-ons portal to guarantee authenticity, then initiate the connection process directly from your enterprise console by scanning the provided QR code with your mobile device to establish a secure, policy-bound link.


For accessing decentralized applications, the connected plugin automatically proposes transactions for multi-party approval according to your organization's predefined governance rules; you must then review and authorize these actions on your mobile hardware, ensuring no single device holds complete signing power. This separation of duties between the browser interface and the physical authorization device fundamentally secures your interaction with Web3 protocols against unauthorized access.


Should you encounter a "No vaults found" error or need to reconnect after a browser reset, re-scan the pairing QR from your administrative dashboard–your asset policies and user permissions remain intact server-side, so this local re-linking action restores full functionality without requiring a reconfiguration of your entire treasury security model.

FAQ:
I installed the Fireblocks browser extension but can't see my existing vault accounts. What's wrong?

This is a common first step. The extension itself is a fresh interface. To access your organization's vaults and wallets, you must first log in. Click the extension icon and select "Login with Fireblocks". You will be redirected to authenticate using your existing Fireblocks account credentials (like email and password, often with 2FA). Once successfully logged in, the extension will connect to your Fireblocks workspace and display the vaults and wallets your user permissions allow you to interact with.

Can I recover access to my dapps if I uninstall the Fireblocks extension or switch computers?

Yes, your dapp connections are not stored solely on the local extension. They are managed by your Fireblocks organization's policy engine. When you reconnect the extension on a new browser or device and log into your Fireblocks account, your wallet addresses will be the same. You will need to manually reconnect these addresses to the dapps (like a DeFi platform) by selecting the Fireblocks wallet when the dapp prompts for a connection. Your transaction approvals will still follow the same configured policies, requiring the necessary approvals from other members in your workspace.

What's the difference between connecting a dapp to the extension versus using the Fireblocks web console?

The extension is for direct, in-browser interaction with dapps. When a website like Uniswap asks to connect a wallet, you use the extension to select which vault and asset address to link. The web console is your administrative dashboard. You use it to set up vaults, define transaction policies, add users, and review audit logs. You initiate manual transfers from the console. For active trading or interacting with a dapp's interface, the extension is the necessary tool that bridges your managed assets to the web application.

I approved a transaction in a dapp, but it's stuck. The extension shows "Transaction initiated" but nothing happens.

The "Transaction initiated" status means the extension has forwarded the transaction details to the Fireblocks platform for processing according to your organization's policies. The delay is not with the extension. Log into your Fireblocks web console and check the "Transactions" feed. The transaction is likely pending the required number of approvals from other policy managers in your workspace. Once the final approver completes their step in the web console or via email approval, Fireblocks will broadcast the transaction to the blockchain. The extension status will then update.

Is my private key stored inside the Fireblocks browser extension?

No. The Fireblocks extension does not hold or ever have access to your private keys. This is a core security design. The extension acts as a secure communicator. It signs transaction messages locally using a unique key pair, but this is only for authentication with the Fireblocks service. Your actual cryptocurrency private keys are secured in Fireblocks' distributed, offline MPC (Multi-Party Computation) vaults. The extension sends partially signed requests to these vaults, which require additional approvals per your policy before a transaction is completed. No single device holds a full 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-managed accounts?

This usually happens when the extension is connecting to a new or different Fireblocks Workspace. The extension accesses wallets linked to the specific Workspace you log into. To recover your existing accounts, first confirm you are logging in with the exact same email and organization credentials used for your original setup. If you're unsure, check your invitation email from Fireblocks Wallet Chrome extension. After login, ensure you've selected the correct vault account within the extension's interface. If your wallets were managed under a different Workspace (e.g., a separate company account), you will need to log out and use the credentials for that specific Workspace. The extension itself does not store wallets locally; it's a gateway to your cloud-based Fireblocks platform vaults.

Can I use the Fireblocks extension to interact with any dapp, and what happens if a transaction fails mid-process?

Yes, the extension is designed to work with any decentralized application that supports WalletConnect or injected Web3 providers like MetaMask. When you connect, Fireblocks acts as your secure signer. If a transaction fails after you've approved it in the Fireblocks web dashboard—for instance, due to a network congestion error or a slippage issue on a DeFi dapp—the outcome depends on the failure point. A blockchain rejection (like an out-of-gas error) means the transaction won't complete and no funds are moved. However, the transaction request itself was still signed and broadcast. You should always check the transaction hash on a block explorer. For subsequent attempts, you may need to re-initiate the action in the dapp, as the extension and Fireblocks platform handle each transaction approval as a distinct event. Failed transactions do not typically affect your wallet's state within the Fireblocks system.
