Verifier CLI

nebula-verify is a standalone CLI that verifies a proof bundle

without contacting Nebula. Useful for auditors, courts, and

counterparties.

Install

npm install -g @nebula/verifier

Or download a pre-built binary from the releases page.

Usage

nebula-verify check ./manifest.json
nebula-verify check ./bundle.zip
nebula-verify dump ./manifest.json

check returns exit code 0 on success; non-zero on failure with a

human-readable message on stderr. dump prints the parsed envelope

without contacting any chain.

Exit codes

  • 0: chain agreement, signing key chain intact
  • 1: chain disagreement (one of Polygon / nebulad does not match

the documented hash)

  • 2: signing key chain broken (the user's key is not signed by an

org key, or the org key is revoked)

  • 3: structural error in the manifest
