• Binary Specification Validation - Checks constructed modules for structural or logical errors to ensure adherence to the WebAssembly specification.
• Binary Optimizers - Provides a transformation engine that applies optimization passes to increase execution speed and reduce WebAssembly binary size.
• Dead Code Elimination - Prunes unused exports and functions through reachability analysis of internal entities and external references.
• Automatic Export Removal - Deletes exported functions or globals from a module to reduce binary size after merging logic.
