# Dev Update Week 13: Implementation of the Hybrid Ethereum VM 2 **Developer:** Developeruche **Week Ending:** September 7, 2025 ### Summary Progessing from last week's update, was able to make good progress on the Hybrid node, finished the first phase of the `mini-evm-interpreter`, this interpreter can not run in the RV64 emulator, following the proposed path of implementation by the ipilison team. During the course of the week was also able to push out some documenation. ### Accomplishments This Week * **mini-evm-interpreter:** Finish the implemenation of the mini-evm-interpreter and also intergrating it with the hybrid RETH node. * **RETH coupling:** Coupled a RETH node with the hybrid evm and mini-evem interpreter enabling the execution of RUST smart contracts and Solidity smart contracts. * **documentation**: Some documentation on installation, contract creation and deployment was release also. [code](https://github.com/developeruche/hybrid) [mini evm code](https://github.com/developeruche/hybrid/tree/main/bins/mini-evm-interpreter) [documentation](https://hybrid-book.vercel.app/) ### Next Steps & Goals for Next Week 1. **mini-evm-interpreter:** Would need to finish up some extra opcodes still lacking in the interpreter. 2. **Gas Metering Model Exploration:** Begin drafting a gas metering strategy that balances fairness across both RISC-V and EVM execution paths. 3. **Testing and Validation:** Run basic test cases of EVM contracts executed via the `mini-evm` inside the RISC-V sandbox. 4. **Documentation:** Make more progress on the documenation, this is very important, make this research result more replicated.
