Fireblocks wallet extension setup and dapp recovery guide



Fireblocks Wallet Extension Setup and DApp Recovery Process Guide

Install the browser add-on solely from the official Chrome Web Store or Firefox Add-ons portal; third-party sources risk asset compromise.

Initial Configuration Steps

Launch the installed add-on and select 'Create New Vault.' You will define a minimum of three transaction authorization policy participants. Assign distinct roles–like 'Admin' and 'Transaction Approver'–to different team members or your own devices to enforce security controls.

Securing Your Keys

The system generates a unique Recovery Packet. This file is encrypted and password-protected. Store it in three separate, secure physical locations–such as encrypted USB drives in safety deposit boxes. Memorize the packet's password; losing it renders the packet useless.


Connect your vault to a blockchain network. Navigate to the 'Asset Management' section, select a network like Ethereum, and note the provided public address. This address becomes your destination for digital asset transfers.

Re-linking to Decentralized Applications

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


Open the cryptographic add-on in your browser and ensure you are signed in.
Visit the specific application's website that requires access.
Locate the 'Connect' button on that site–typically in the top-right corner.
A connection prompt will appear. Select the installed add-on from the list of options.
Within the add-on's pop-up, choose the specific vault account you wish to link and authorize the connection.

Address Mismatch Resolution

Sometimes, an application displays an unexpected public key. This often occurs because the site is connected to a different vault or network within your add-on.


Go to the add-on and manually disconnect the application from all vaults.
Clear the application's site data (cookies and cache) in your browser settings.
Re-initiate the connection process from step 2, double-checking you select the correct vault and network (e.g., Ethereum Mainnet vs. Polygon).


For persistent issues, verify the network compatibility. The decentralized application must operate on a blockchain your vault is configured for. Add the required network via the add-on's asset management interface before attempting reconnection.


Transaction failures usually stem from policy thresholds. A transaction requiring two approvals cannot be signed by a single party. Ensure the necessary number of authorized users review and approve the pending action in their respective add-on interfaces.

Install the browser add-on exclusively from the official Chrome Web Store or Firefox Add-ons portal to eliminate the risk of counterfeit software intercepting your credentials.


Configuration demands defining transaction policies within your enterprise dashboard before the plugin becomes operational; assign specific asset types and spending limits per user role, mandating multi-signature approvals for transfers exceeding predefined thresholds to enforce granular financial controls.


If you lose access to a browser profile, reconnect by downloading the add-on again and scanning a new QR code generated in your institution's console–this re-links the local interface without moving assets, as cryptographic keys remain secured in your organization's MPC infrastructure.


Always verify the full domain name of a decentralized application before signing; a mismatched character indicates a phishing site designed to drain accounts.

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

This is a common point of confusion. The Fireblocks browser extension itself does not store your vaults or assets. It is a connection tool. Your assets remain secured in the Fireblocks MPC-CMP infrastructure. The extension needs to be linked to your Fireblocks workspace. Ensure you are logging into the extension with the exact same email and credentials you use for your Fireblocks web console. Once authenticated, the extension will mirror the vaults and policies your account has access to, allowing you to interact with dapps.

Can I recover access to my decentralized applications if my Fireblocks setup is lost?

Yes, but the process depends on what was lost. If you lose access to the browser extension (e.g., switch computers), you simply reinstall it and log in with your Fireblocks credentials. Your dapp connections are not stored locally. However, if you lose access to your Fireblocks organization entirely (admin account), recovery is a formal process managed by your organization's administrators using the configured policy rules and designated backup key custodians. Individual users cannot recover this independently.

How does transaction signing work with the extension compared to the web platform?

The extension streamlines the process for dapp interactions. When you initiate a transaction on a website, the extension intercepts the request. It then presents the transaction details within the extension's interface for review. Approval follows your workspace's policy: it may require a single user's confirmation or multiple approvals based on rules. Once the policy is satisfied, the extension facilitates the signing using Fireblocks' secure MPC technology without exposing private keys. The web platform is better suited for batch operations, internal transfers, or complex policy management.

Are there security risks in connecting the Fireblocks extension to any dapp?

While the extension enforces your transaction policies, it cannot assess a dapp's intent. The main risk is approving a malicious transaction crafted by a compromised website. The extension shows you transaction data (like recipient address and amount). You must verify these details match your expected action. A fake site might mimic a real one but request funds to a thief's address. Always double-check the URL of the dapp and the transaction parameters the extension displays before approving.

I approved a transaction from a dapp, but it's stuck. What can I do?

First, check the transaction status directly in your Fireblocks web console under the 'Transactions' tab. The most frequent cause is an incomplete policy approval. If your transaction requires multiple signers, your approval was only the first step. Others must also approve. Another possibility is network congestion; the transaction may be pending on the blockchain. The console will show its status. Do not attempt to re-sign the same transaction from the dapp, as this could lead to a duplicate. Use the console for tracking and resolution.
