Enabling efficient and secure relaying of cross-chain transactions

Relayers are important for increasing the security of cross-chain transactions, as they can help to ensure that assets are transferred correctly and securely. This can help to reduce the risk of transaction failure and prevent the loss of assets due to errors.

A key infrastructure component to enable interoperability and cross-chain communication, cross-chain relayers are essential for realizing the full potential and adoption of the Cosmos ecosystem.


Powered by Carbon, Hydrogen is a decentralized cross-chain relayer network for Carbon. At launch, the dApp is separated into 2 phases.

Phase I: Monitoring Dashboard

Hydrogen's monitoring dashboard enables users to have access to a detailed view of all cross-chain transactions between Carbon and other blockchains.

Feature customizations include β€”

  • Search easily by txn hash/address hash/address

  • Choose the number of rows of txns you want to view

  • Filter by dates: Click and drag, or select your range manually

  • Click on the source/bridge/destination hash and be brought to the blockchain explorer

Under β€˜Details’, users have access to more transparent information, from Source and Bridging to Destination Transaction:

Phase II: Relayer Network πŸ”œ

Relayer networks are systems deployed on top of blockchains (e.g. Carbon) that facilitate order-matching, while ensuring transactions are verified and validated by the network.

Hydrogen's decentralized relayer network is designed to create a more resilient and efficient platform, reducing the chances of incidental failure for Carbon as a whole. Through the network, relayer groups can support Carbon by setting up relayers and launching cross-chain dApps with Carbon's modules.

Such connectivity will amplify the accessibility of tokens and availability of dApps among the various blockchains ecosystems.
