This upgrade features 100% EVM compatibility, letting developers build smart contracts in Solidity and Vyper, as well as a new and improved Rust SDK.Upgrading Developer ExperienceIn December 2023, Fluent launched a preliminary zkWasm developer version of the Fluent L2. This version was explicitly designed to facilitate the deployment of Rust smart contracts using the Fluent Rust SDK. Today, we are rolling out Private Devnet V2. This version consists of two key enhancements:Rust SDK enhancements100% EVM compatibilityIt was time to level up how Fluent supports Rust smart contracts. In this release, we improved code standardization by adding input capabilities with block and transaction context information (block hash, origin, caller, etc.) and improved the developer experience by introducing a new ABI codec to manage input and output parameters. Additionally, Fluent became 100% compatible with the Ethereum Virtual Machine (EVM), opening up a vast ecosystem of existing Ethereum smart contracts and tools. Fluent developers can now build smart contracts in Solidity and Vyper and use tools such as Hardhat. The aim is to make it as simple as possible to deploy Ethereum-centric apps on Fluent, and in the future, enable seamless composability between Ethereum-based smart contracts and those written in traditional programming languages. This opens up the design space for novel apps previously impractical using blockchain-based infrastructure.Onboarding More Launch PartnersIn tandem with the V2 release, we are excited to onboard our second batch of launch partners. A few of our Solidity and EVM-centric partners include Polymer Labs, Archetypal Labs, Rocknverse, 3cities and more. If you're excited about the future of zkWasm on Ethereum and want to start building on Private Devnet V2, we invite you to join our early builders program. If you want to skip the line, feel free to DM Dino or Stephy with what you are building and why you think Fluent is a good match.Other Ways to Get InvolvedIf you’re not quite ready to build on Fluent but still want to participate, there are several ways to get involved:Check out and offer feedback on our docsAsk questions and discuss ideas on DiscordFollow and engage with @fluentxyz on XExplore open positions at Fluent
