WebAssembly (Wasm)

A portable binary instruction format that lets code written in languages like Rust run efficiently in sandboxed environments. Soroban smart contracts compile to Wasm.

Wasm gives blockchains a fast, deterministic, language-agnostic execution target. Soroban compiles Rust to Wasm; several other chains use it too, making Wasm skills transferable across ecosystems.
