What's the type of genesisHash? You could potentially send raw binary from Uint8Array to Rust via &[u8] or Vec<u8> much more cheaply than via string (no Utf16 to Utf8 conversion necessary).

it's of type Hash that extends H256, and H256 extends U8aFixed, and U8aFixed extends Raw, which is a wrapper
around Uint8Array that implements IU8a.
i tried to send Uint8Array as you mentioned in this commit d921638, but not sure how to convert the bytes to string.
i also tried https://crates.io/crates/serde-wasm-bindgen/0.4.2 serde_wasm_bindgen::from_value without any luck
