A new era for inter-chain dApps has come! We are excited to announce that the Celer Inter-chain Message (Celer IM) framework has launched on mainnet. Through Celer IM, developers can build inter-chain dApps using the Celer Inter-chain Message SDK with efficient liquidity utilization, coherent application logic, and shared states across multiple blockchains. Users of Celer-enabled dApps will enjoy the benefits of a diverse multi-blockchain ecosystem with the simplicity of a single-transaction UX from a single chain.
Celer IM has been celebrated and immediately adopted by multiple dApps. Many of the envisioned use cases are being built by our community developers. For example, ChainHop, a composable inter-chain liquidity protocol built using Celer IM, has also launched on mainnet today. Using ChainHop, users and developers can easily convert token X on chain A into token Y on chain B with just a single transaction.
In addition to ChainHop, we have 8 other launch partners: SynFutures, Mystiko, Swing, FutureSwap, Ooki, Rubic, Solace, and Aperture. They are building inter-chain native dApps in the spaces of cross-chain governance, cross-chain yield aggregators, cross-chain synthetic asset trading, cross-chain privacy and other innovative use cases.
The Celer IM framework is very easy-to-use and allows a “plug’n’play” upgrade that often requires no modifications with already deployed code. Developers can easily try out Celer IM by going through the documentation, smart contract framework, and sample application code. If you are interested in building inter-chain dApps and participating in our upcoming ecosystem developer grant program, please reach out to us!
A Wide Range Of Use Cases on Celer IM
Since we announced Celer IM on testnet, we have received an overwhelming amount of interest from the developer community to build inter-chain dApps. A wide range of different use cases of the Celer IM framework is being adopted by prominent protocols to expand both their utilities and to enlarge their user bases. We want to introduce them as Celer IM’s launch partners!
First of all, we want to highlight that ChainHop, a composable cross-chain liquidity protocol built on top of Celer Network, has also launched on mainnet today. ChainHop takes the complex multi-step process of swapping tokens across different chains and simplifies it into an easy single transaction user experience (UX). Using ChainHop, users can easily convert token X on chain A into token Y on chain B with just a single transaction. Additionally, ChainHop is highly composable with other dApps allowing developers to easily access the cross-chain liquidity protocol in order to build other inter-chain dApps.
Similarly, Rubic, a multi-chain swap protocol, is also enabling this one-click functionality across multiple blockchains. Key cross-chain interoperability infrastructure, Swing, is simplifying the cross-chain transaction process by eliminating the need to make several manual commands on multiple networks when communicating with other Celer IM dApps with a single transaction.
Celer IM is widely applicable to build inter-chain DeFi applications as well. The decentralized derivatives protocol SynFutures is using Celer’s IM framework to support multi-blockchain futures trading, allowing users to leverage liquidity from any blockchain. Ooki, a powerful and fully decentralized margin trading, borrowing, and lending platform, is leveraging Celer IM to enable fee bridging among all of Ooki’s different blockchain deployments. Aperture, a cross-chain, community-driven marketplace for DeFi strategies, is leveraging Celer IM to enable one-click access to supported strategies for users from any blockchain. Solace, a decentralized insurance protocol that allows users to insure positions for over 180 DeFi protocols with one policy, is also integrating Celer IM for cross-chain insurance functionality.
Of course, Celer IM can be used in many other use cases besides DeFi applications. FutureSwap, the first decentralized, AMM-based trading protocol to offer leverage on any AMM-backed pair, is enabling cross-chain governance functionality; and to scale its non-custodial crypto margin trading. Mystiko Network, the base layer of web3 that provides both connectivity and confidentiality to all blockchain data, transactions and applications, uses Celer IM to enable privacy protection against unwanted cross-chain data tracking and exploits.
With the Celer IM framework’s mainnet release, we look forward to more exciting use cases to be created by our amazing developer community such as cross-chain NFT marketplaces and omnichain NFT.
How To Get Started With Celer IM
Getting started with Celer IM is easy. To understand the kind of applications and design patterns made possible, you can read the Celer IM introduction or watch this presentation. To go through a hands-on integration process, you can either watch the above video tutorial or run through this integration guide with a simple batch transfer example. If you encounter any issues during integration, please feel free to go to the #celer-interchain-message channel in our discord and let our developer support team know! We will be more than happy to help! If you are interested in working on some use cases and would like to get our support, please fill out this form to get priority consideration for our upcoming developer grant program! With the Celer IM mainnet launch, we look forward to a vibrant inter-chain dApp ecosystem building on top of Celer and can’t wait to see what kinds of exciting use cases get built!
