Bridges Overview

Gnosis' native bridges allow for sending tokens and data, and are run by a group of trusted bridge validators. There is a roadmap to move towards trustless bridges.

There is a growing ecosystem of 3rd-party Bridges that build on top of native bridges, that provide users with fast liquidity and user experience.

Gnosis' native bridges are first-class citizens in the chain's architecture due to the native xDai bridge's integral role in minting and burning the native xDai token used for gas.

Conceptual Architecture

Gnosis has three main types of bridges:

  • Native Bridges: built into the chain itself, and mint the canonical token representation of the original asset on Gnosis (e.g. "Canonical Dai", "Canonical ETH")
  • 3rd-party Bridges: these are maintained by 3rd parties and allow users to swap for canonical tokens created by native bridges
  • Application-Specific Bridges: some applications may provide custom bridges that maintain their own canonical token on Gnosis

Diagrams overview of Bridges

Native Bridges

Gnosis has two native bridges:

  • xDai Bridge that is used to mint the native stablecoin by bridging Dai from Ethereum
  • Omnibridge and underlying Arbitrary Message Bridge that are used for bridging tokens and data

Bridging Dai

See the xDai Bridge.

Bridging Data

See the Arbitrary Message Passing Bridge or AMB Bridge for short.

Bridging Tokens

See the Omnibridge, which is built on top of the Arbitrary Message Passing Bridge.

Canonical Bridged Tokens

Tokens that are bridged using Omnibridge are regarded as canonical representations of the origin token on Gnosis Chain.


Gnosis has a long-term roadmap to move towards trustless bridges, and is actively funding research and development in this area.
