curvy-wasm

wasm-bindgen exports for curvy-core: Poseidon, seed-backed and direct-scalar BabyJubjub signing, note encryption and commitments, Merkle trees, witness-input builders, and stealth addressing.

This crate is the JavaScript binding for core cryptography and tree operations. Groth16 proving is emitted as a separate WASM module by curvy-prover, allowing applications to ship only the functionality they use.

Build

Use the workspace scripts rather than invoking wasm-bindgen manually:

scripts/build.sh wasm-nodejs
scripts/build.sh wasm-web
scripts/build.sh wasm-bundler
scripts/build.sh wasm-web-threads

Portable builds are single-threaded. The threaded browser build exports initThreadPool(n), requires cross-origin isolation, and uses n as this module's worker-pool size.

The generated TypeScript declarations are the JavaScript API reference for each concrete output package. Rust item documentation on docs.rs/curvy-wasm describes the underlying wasm-bindgen exports and boundary validation.

Both signing profiles are supported:

JavaScript API	Profile
`pubFromPrivateKey`, `sign`	Seed-backed BLAKE-512/prune derivation
`pubFromScalar`, `signWithScalar`, `verifyScalarSignature`	Checked direct-scalar derivation

See the workspace guide for exact output directories, per-target requirements, and worker-budget configuration.
