Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff encoded-string-file:dist/vendored-chain-specs.js AI (source-diff): Long strings are blockchain chain-spec JSON (boot nodes, genesis data); generated by documented update script, not obfuscation. ai
source-diff obfuscated-file:dist/vendored-chain-specs.js AI (source-diff): Long lines are JSON blockchain chain-spec data serialized as string literals, not obfuscated code. ai
source-diff obfuscated-file:dist/vendored-chain-specs.d.ts AI (source-diff): TypeScript declaration file mirrors the same chain-spec string data; not obfuscated code. ai
source-diff source-size-tripled AI (source-diff): Size increase is entirely explained by the addition of vendored chain-spec JSON data files. ai
npm-metadata suspicious-initial-version AI (npm-metadata): Intentional placeholder/namespace-reservation package; 0.0.0 is expected. ai
bogus-package bogus-package AI (bogus-package): Explicit stub package with no code by design; all signals are expected for a namespace placeholder. ai

v0.0.17

2 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: wpar.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.0.16

3 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: wpar.

HIGH Long encoded string in modified file: dist/vendored-chain-specs.js source-diff

Modified file contains 3 long encoded string(s) (200+ chars). These are commonly used to hide malicious payloads.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.0.11

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v0.0.8

3 findings
HIGH New obfuscated file: dist/vendored-chain-specs.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH New obfuscated file: dist/vendored-chain-specs.d.ts source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.0.7

3 findings
HIGH New obfuscated file: dist/vendored-chain-specs.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH New obfuscated file: dist/vendored-chain-specs.d.ts source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.
