Subsembly is a framework used for designing and implementing Substrate runtimes from scratch. Subsembly utilises Substrate Core to build runtimes in a non-native language of Substrate. With Subsembly you can build Substrate runtimes rapidly, with a varying degrees of technical freedom.
Substrate runtimes can be designed in any other language than Rust, provided that the language targets WebAssembly. This is where AssemblyScript and Subsembly come into play.

Subsembly is funded by Web3 Foundation Grants and developed, maintained by LimeChain.
