Introduction

Snowbridge is a general-purpose, trustless, and decentralized bridge between Polkadot and Ethereum. It is part of the Polkadot SDK and exists as a common-good bridge on BridgeHub. Ethereum contracts and other off-chain infrastructure (e.g. relayers, end-to-end tests) can be found in our Github repository.

Snowbridge launched on the Polkadot mainnet in June 2024 (https://app.snowbridge.network) and has been running smoothly ever since. The bridge's total locked value (TVL) exceeds $70 million USD.

Key features that set Snowbridge apart from other bridges:

  • Owned by the Polkadot community

  • Trustless, no multisigs

  • Integrates seamlessly into AssetHub

  • Uses XCM as message format

The Snowbridge team continues to develop new features and enhance the bridge. For updates on Snowbridge, follow our account on X.
