# Reproducible builds are produced by two coexisting paths
# (see `docs/reproducible-builds.md`):
#   1. The Nix derivation at `nix/mpc-contract.nix` (exposed as
#      `packages.<system>.mpc-contract` in `flake.nix`).
#   2. cargo-near, driven by the NEP-330 metadata below. The pinned
#      `sourcescan/cargo-near` image lets third-party verifiers
#      (sourcescan.io, nearblocks) replay and verify the on-chain WASM.

# fields to configure build with WASM reproducibility, according to specs
# in https://github.com/near/NEPs/blob/master/neps/nep-0330.md
