Lido Satellite Contract
The Lido Satellite contract enables bridging of Lido’s staked ETH (stETH) to Neutron. It provides a TokenFactory representation of the wrapped staked ETH (wstETH) which can be used throughout the Neutron ecosystem.Supported Tokens

How the Bridge Works
- Axelar Integration: The Neutron bridge uses Axelar’s General Message Passing (GMP) to facilitate cross-chain communication
- Minting and Burning: When wstETH is bridged to Neutron, the corresponding tokens are locked on Ethereum, and native tokens are minted on Neutron
- Token Standards: TokenFactory standards on Neutron ensure that the bridged tokens behave like native Cosmos assets
- Fee Mechanics: The bridge charges a small fee for transfers to cover operational costs
Using the Bridge
To interact with the bridge, you can use the Neutron Bridge UI or interact directly with the contracts.Example Bridge Queries
Bridge Security
The bridge security model includes:- Axelar Validators: The bridge relies on Axelar’s validator network for secure message passing
- Multi-Signature Controls: Administrative actions require approval from multiple parties
- Rate Limiting: The bridge includes rate limits to prevent catastrophic failures
- Upgradability: The bridge can be upgraded to patch security vulnerabilities
Future Bridge Developments
The Neutron team is working on expanding bridge capabilities to include:- More assets and token standards
- Additional source chains beyond Ethereum
- Improved efficiency and reduced fees
- Enhanced user interfaces for easier bridging
