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:codec/block/encode.spec.js AI (source-diff): Long byte array in a test file is a Uint8Array expected-value fixture for codec unit tests, not an obfuscated payload. Normal pattern for serialization libraries. ai
source-diff source-size-tripled AI (source-diff): Type definitions package for Polkadot network; size growth reflects addition of new type definitions as the network evolves. No malicious indicators present. ai
publish-pattern new-deps-added AI (publish-pattern): @babel/runtime is a canonical Babel helper package; adding it is a routine Babel 7 migration step with no malicious indicators for this package. ai
provenance no-provenance AI (provenance): Long-established polkadot-js package predating Sigstore provenance; trusted publisher with 2313 approved packages and 0 rejections. ai
