Celer IM Overview

Celer IM fundamentally changes how multi-blockchain dApps are built and used. Instead of deploying multiple isolated copies of smart contracts on different blockchains, developers can now build inter-chain-native dApps with efficient liquidity utilization, coherent application logic, and shared states. Users of Celer IM-enabled dApps will enjoy the benefits of a diverse multi-blockchain ecosystem with the simplicity of a single-transaction UX, without complicated manual interactions across multiple blockchains.

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. As an example, Uniswap and Sushiswap can be transformed into a cross-chain DEX with just a simple plug-in. There have been some projects that implemented this functionality in production such as ChainHop and Rango Exchange.

In the above cross-chain DEX example, a user of Sushiswap can swap their ETH on Arbitrum to BNB on Binance Smart Chain (BSC) with a single, simple transaction. Behind the scenes, the following has happened:

• ETH -> USDT on the Arbitrum-side via Sushiswap

• USDT on Arbitrum is bridged to BSC via cBridge as part of the Celer IM framework

• An inter-chain message to execute a USDT->BNB swap is sent to BSC via Celer IM

• USDT -> BNB swap on BSC-side Sushiswap is triggered by that remote call on Sushiswap
