Using Fireblocks with OPUS Pool

Everything you need to know to use Fireblocks with OPUS Pool

Overview

In order to integrate OPUS Pool with Fireblocks, we will be using the built in WalletConnect functionality to gather the information we need to connect your Fireblocks account to OPUS Pool.

As a brief overview, WalletConnect is an open-source protocol that enables secure and decentralized connections between various blockchain wallets and dApps (decentralized applications). Users can interact with dApps like OPUS Pool from their mobile wallets to manage and execute transactions without exposing private keys.

Fireblocks is a secure and enterprise-grade platform designed to manage digital assets and crypto transactions, providing solutions for securely transferring, storing, and issuing digital assets, with features like multi-party computation (MPC) and a network of trusted partners.

So how do we get these two interfaces to work together to integrate with OPUS Pool? Read on!

Step 1: Connect to OPUS Pool via WalletConnect

When first landing on the OPUS Pool page, click on the 'Connect wallet' button in the upper-right hand side of your screen.

Next, you will be prompted with a connection method. In this case, we are choosing WalletConnect as illustrated below.

You'll see a screen like the following:

Note we have two options here, the QR code, or the Fireblocks button.

Step 2: Choosing Your Connection Preference

From here, you'll have two options on how to proceed.

1.) Connect to your Fireblocks account via the Fireblocks button.

• This can be done via your web browser, however, signing transactions will still be done via Fireblocks on your mobile device.

2.) Connect to OPUS Pool via the Wallet Connect QR code from your Fireblocks account.

• This will require the use of a mobile device to access your Fireblocks account. Signing will also take place via your Fireblocks app on your mobile device.

Either option is equally viable, it just comes down to which you prefer.

To connect directly via your Fireblocks account, please read on for Option 1: Connecting via Fireblocks.

Alternatively, to connect via QR code, skip ahead to Option 2: Connecting via QR Code.

Option 1: Connecting via Fireblocks

From the WalletConnect popup window we saw before, select the Fireblocks button to the right of the MetaMask and Ledger buttons.

This will open a new browser tab where you will be prompted to first login to your Fireblocks account then connect your Fireblocks vault to OPUS Pool.

• You'll see a screen similar to the screenshot below:

Next, leave this window open and navigate back to the tab where you have OPUS Pool open in your browser.

Now you should see your wallet connected and you will be ready to stake using the OPUS Pool interface.

When you finalize your transactions, you will need to sign via your Fireblocks app on your mobile device.
