Fireblocks signing in Guardian UI

1. Enabling Fireblocks Remote Signing:

When creating a user, select the “Use fireblocks signing” option and populate the following fields with values from your Fireblocks account configuration:

• Fireblocks Vault ID

• Fireblocks Asset ID

• Fireblocks API Key

• Fireblocks Private Key

Users, which have been created with this option enabled to remotely sign their Hedera transactions using Fireblocks API instead of via the built-in Guardian signing workflow.
