Quest 2 - Cross-chain Messages

In this quest, we’ll be focusing on cross-chain messages and applications within the Linera framework. Throughout this quest, you'll learn how multi-chain applications operate, maintaining unique states across different chains while sharing the same application ID and bytecode. We'll start with the basics, such as defining message types and using ContractRuntime to dispatch messages.

Further, we will delve into practical scenarios involving a fungible token application to demonstrate token transfers and handling of cross-chain communications. This includes operations like token debiting, crediting, and ensuring secure communication across chains.

By the end of this quest, you'll gain a comprehensive understanding of dynamic cross-chain interactions in Linera!
