solx: The New Solidity Compiler - For Toolchain Builders

The solx compiler, powered by LLVM, introduces a modular, flexible way to build and maintain Solidity compilers for Ethereum and other EVM-compatible environments. Tailored for toolchain developers, solx allows them to focus separately on the front-end (source to LLVM IR) or the back-end (LLVM IR to target machine code), unlocking a cleaner pathway for experimentation and adaptation. By leveraging LLVM’s vast existing infrastructure, solx reduces maintenance complexity, boosts tooling potential, and opens the door to new language innovations—potentially leading to custom smart contract languages like “Rust for EVM.”
