Snowbridge Dashboards

Overview​

Snowbridge is a general-purpose, trustless, and decentralized bridge that connects Polkadot and Ethereum. This bridge facilitates communication between any Polkadot parachain and Ethereum using Polkadot's XCMP messaging protocol. Parachains can send XCM instructions to BridgeHub, leveraging Snowbridge for cross-chain interactions.

For more details on bridging with Kusama, please refer to our BridgeHub Dashboard.

Here you will find a variety of dashboards that help visualize data from the Snowbridge protocol:

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

Key Tables​

Data from the Snowbridge protocol is organized into several key tables:

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

Getting Started with Queries​

To get started with querying data from Snowbridge, you are welcome to use the mentioned materialized queries. You can use the following DuneSQL queries as examples:

Polkadot BridgeHub Outbound Msg Sent To Ethereum
SELECT DISTINCT
  block_time,
  block_number,
  block_hash,
  extrinsic_id,
  extrinsic_hash,
  event_id,
  section,
  method,
  CAST(JSON_VALUE(data, 'strict $[0]') AS VARCHAR) AS message_id,
  CAST(JSON_VALUE(data, 'strict $[1]') AS uint256) AS nonce
FROM
  bridgehub.events
WHERE
  section = 'ethereumOutboundQueue'
  AND method = 'MessageAccepted';

Query result:
