Leverage Internet Computer's new Chain Fusion technology to build a multichain dApp which integrates ICP with Bitcoin, Ethereum or another EVM chain, or improve on an existing dApp. Using Chain Fusion, you will notice, connecting the two chains requires no bridge, oracle, or intermediary service, and ICP canister smart contracts are capable of signing Ethereum transactions directly via threshold ECDSA, as well as interacting with EVM RPC providers directly using HTTPS Outcalls. 

Which Chain Fusion use case you will decide to pursue is entirely up to you, whether you want to go for automating tasks on Ethereum, or using the EVM RPC canister as a co-processor for your EVM app and building a fully on-chain app with on-chain computing capabilities. Likewise, you are free to use the ckBTC and ckETH tokens and to build a DeFi application, or delve into SocialFi and DAOs! The only requirement is that your dApp utilises one or more key aspects of Chain Fusion. How your practical implementation of Chain Fusion will look like and what the final dApp will do is also up to you.

To start using Chain Fusion, you can take a look at the Chain Fusion Starter repository, which integrates with the EVM RPC canister, including a dev container with all necessary dependencies preinstalled. This way, all the heavy lifting with regards to the coprocessor logic is done for you already. Building from scratch is also welcome, of course!
