Solang is a modern Solidity compiler written in Rust that enables developers to compile smart contracts for multiple blockchain platforms beyond Ethereum, such as Solana, Polkadot, and Soroban. Unlike the traditional Solidity compiler, which targets the Ethereum Virtual Machine, Solang focuses on portability by translating Solidity code into native execution environments for different blockchains. It uses the LLVM compiler framework to generate optimized output, often producing WebAssembly or platform-specific binaries that improve execution efficiency and reduce resource consumption. The project maintains compatibility with Solidity 0.8 syntax while adapting to the unique constraints and capabilities of each target blockchain. Its architecture includes parsing, semantic analysis, intermediate representation generation, and final compilation through LLVM, making it a full-featured compiler pipeline.
