BridgeHub
Multi-chain bridge for seamless asset transfer.


Overview:
BridgeHub is a system parachain in the Polkadot ecosystem designed to enable secure, trustless interoperability between Polkadot, Kusama, Ethereum, and other chains. It implements on-chain light clients (using BEEFY and GRANDPA), message‑passing pallets, and XCM support to deliver robust cross‑chain bridges like Snowbridge and the Polkadot–Kusama bridge.
What We Delivered:
Integrated GRANDPA and BEEFY light clients enabling Polkadot, Kusama, and Ethereum to directly verify each other’s state, removing reliance on centralized relayers.Created a suite of Substrate pallets—Bridge GRANDPA, Parachains, Bridge Messages, and XCM Bridge—for secure, verifiable cross-chain messaging and asset transfers.Enabled general-purpose, trustless bridging between Ethereum and Polkadot parachains via Snowbridge, leveraging BridgeHub for cross-consensus communication.Supported Dune-style dashboards tracking on-chain events enabling visibility into outbound message rates and bridge health.
Outcome:
Since its launch in late 2023–early 2024, BridgeHub has become the core trustless interoperability layer for Polkadot and Kusama, facilitating real-time, permissionless, finality-verified asset and message transfers—ushering in a new era of multi-chain connectivity.
