Omni Bridge launches with a hybrid architecture, utilizing different verification methods based on chain-specific requirements and technical constraints. This approach allows us to support multiple chains from day one while progressively transitioning to full Chain Signatures integration.

​
Supported Chains

The bridge currently supports the following networks:
  • EVM Chains:
    • Ethereum
    • Base
    • Arbitrum
    • BNB Chain
    • Polygon (PoS)
  • Non-EVM Chains:
    • Bitcoin
    • Solana
    • Zcash

​
Architecture Overview

Omni Bridge utilizes Chain Signatures as its primary verification mechanism for outbound transfers from NEAR. Incoming transfers rely on chain-specific verification methods, including light clients for maximum security where available.

​
Verification Methods

  • Ethereum & Bitcoin: Light Client verification for inbound transfers.
  • Other Chains: Message passing protocols verified by the NEAR network.
  • Outbound (All Chains): Chain Signatures (MPC) for secure transaction signing.

​
Future Development

  1. Protocol Improvements
  • Enhanced fee mechanisms
  • Cross-chain contract calls
  • New token standards support
Beyond basic asset transfers, we’re expanding the bridge’s capabilities. Enhanced fee mechanisms will better handle gas price volatility, while cross-chain contract calls will enable more complex interactions.
  1. Infrastructure
  • Expanded relayer network
  • Improved monitoring tools
  • Enhanced developer tooling
Infrastructure development focuses on reliability and usability. An expanded relayer network improves transfer speeds and reliability, while better monitoring and developer tools make integration and maintenance easier.

Areas for Contribution

The code is open source and we welcome contributions from the community. Whether you’re interested in adding support for new chains, optimizing performance, or building developer tools, there’s room for meaningful contribution. Bridge infrastructure is a fundamental component of a multi-chain future. Through Chain Signatures, we’re creating a more efficient, secure, and scalable approach to cross-chain communication. Join us in building it.
