Seems **C library from Rust compiled to WASM** is [not quite impossible](https://stackoverflow.com/questions/51666736/how-do-i-use-a-c-library-in-a-rust-library-compiled-to-webassembly/51804070) but maybe a better idea to replace with some pure Rust implementation alternative like [libsecp256k1-rs](https://github.com/ETCDEVTeam/libsecp256k1-rs)
