Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

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.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
dependencies unvetted-dep:c-kzg AI (dependencies): c-kzg is the official Ethereum KZG cryptography native binding (ethereum/c-kzg-4844); its use in a blob/EIP-4844 library is expected and legitimate. ai
phantom-deps phantom-dep:tslib AI (phantom-deps): tslib is declared as a runtime dependency and is a well-known implicit dependency of TypeScript-compiled packages; stable false positive for this package. ai
semgrep semgrep:hex-decode AI (semgrep): Hex decoding in blob-lib is standard Ethereum blob/KZG data handling (stripping 0x prefix). Legitimate cryptographic use, not obfuscation. ai
bogus-package bogus-package AI (bogus-package): Missing metadata fields are inherited from monorepo root package.common.json. Package has 442 days history, 909 versions, and 12k weekly downloads — clearly not spam. ai
npm-metadata no-description AI (npm-metadata): Description is inherited from monorepo root config. Package is well-established with significant download history. ai
