Fluent is an execution network that integrates different virtual machines. The project includes a zero-knowledge virtual machine (zkVM), a Layer-2 network, and development tools for building blockchain applications on Ethereum. Fluent emulates the execution environment (EE) of various virtual machines (EVM, SVM, Wasm, etc.), enabling smart contracts written in different languages (Solidity, Rust, etc.) to interact within a shared state environment. The network supports atomic composability between applications running on different virtual machines, as well as hybrid applications composed of smart contracts from multiple environments. Interaction between these contracts happens automatically and in real time.
