BridgeHub Dashboards

Overview

Polkadot BridgeHub is a system parachain within the Polkadot ecosystem, designed to enable trustless bridging between Polkadot and other blockchains such as Kusama and Ethereum. It ensures secure cross-chain communication through a combination of on-chain and off-chain components. This dashboard primarily analyzes the bridging information between Polkadot and Kusama.

The Ethereum to Polkadot BridgeHub primarily utilizes Snowbridge. For more details, visit our Snowbridge Dashboard.

Here you will find a variety of dashboards that help visualize data from the BridgeHub parachain:

  • BridgeHub: A comprehensive analysis of BridgeHub, including: Kusama Related On Chain Data Analysis, Analysis of Messages with Kusama.

Key Tables

Data from the BridgeHub parachain is organized into several key tables:

  • bridgehub.balances
  • bridgehub.blocks
  • bridgehub.calls
  • bridgehub.events
  • bridgehub.extrinsics
  • bridgehub.transfers
