What is the Fireblocks Chrome Extension?

The Fireblocks Chrome Extension allows you to connect to Web3 decentralized applications (dApps) using their Rabby integration. dApps recognize the extension as a Rabby wallet, but the extension is connected to your Fireblocks workspace and secure wallet infrastructure. Therefore, any contract calls placed by dApps are subject to your Transaction Authorization Policy (TAP) and secure multi-party computation (MPC) signing, just like any other transaction you make using Fireblocks.

Supported blockchains

You can use the Fireblocks Chrome Extension to connect to dApps on the following blockchains:

• Arbitrum
• Astar
• Aurora
• Avalanche
• Base
• BNB Chain
• Canto
• Celo
• Ethereum
• Ethereum Classic
• Evmos
• Fantom
• Flare
• Kava
• Linea
• Moonbeam
• Moon River
• Oasys
• Optimism
• Polygon
• Polygon zkEVM
• Ronin
• RSK
• SmartBCH
• Songbird
• SX
• WEMIX
• zkSync

New EVM-compatible blockchains are supported automatically. You can see the list of supported blockchains in the extension by selecting More > Supported chains.
