PyO3/maturin bindings for the ed25519-zebra Rust crate, used by Substrate/Polkadot/Zcash for ed25519 signatures. Upstream publishes no riscv64 wheel.

Mirrors upstream's CI.yml linux/sdist jobs.

Differs from upstream

  • Musllinux dropped - rustup ships no riscv64 musl host toolchain.

Testing

  • Exercises ed_verify/ed_public_from_secret against upstream's own tests.py fixed-key vectors instead of test_sign_and_verify_message, which needs py-bip39-bindings, not yet on the registry.

License: OK

Built a cp314 wheel locally from the v1.3.0 checkout on an arm64 host; wheel layout and all test vectors matched.
