JAM still needs a lot of time, and currently the first RISC-V VM that is close to being put into production - PolkaVM (the other one is @ boundless_xyz zkvm, which is also based on RISC-V VM and has already been released in the main network beta version, but it is a more zk version of VM), has been launched on KSM platform (@ polkadot's leading platform). It was launched around June and is currently capable of developing smart contracts that are relatively fully compatible with Solidity. The demonstration program has implemented the Uniswap V2 version to run the complete program, and is compatible with both the Ethereum toolchain (Remix, Hardhat) and popular libraries. On this basis, a recent important update is XCM Precompile (XCM stands for Cross Chain Transport Protocol), which supports language level cross contract calls and integrates XCM functionality directly into existing smart contracts through inheritance or import of IXcm interfaces. This method enables you to seamlessly embed cross chain functionality into application logic. Whether building DeFi protocols, governance systems, or any application that requires cross chain coordination, XCM calls can be directly incorporated into the functionality of contracts. The RISC-V VM Polkadot version should be launched along with Polkadot Hub. Polkadot ecosystem developer @ alice_und-bob predicted the roadmap and timeline for the second half of the year (which may not be entirely accurate) -Polkadot 2.0- Elastic Scaling (August? ) -Polkadot Hub - Developer and User Onboarding Platform (October?)? ) -Polkadot Pay - mobile app (August? ) -DOT ETFs (final approval in November) -DOT Tokenomics 2.0 (still under discussion) He did a good job on this roadmap: XCM-Precompile： https://docs.
