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
source-diff encoded-string-file:bitcore-lib.js AI (source-diff): Bundled DH modp primes and crypto constants; standard for a Bitcoin/crypto library. ai
source-diff encoded-string-file:test/block/block.js AI (source-diff): Hex-encoded Bitcoin block data in test fixtures; expected for this package. ai
source-diff encoded-string-file:test/transaction/input/multisig.js AI (source-diff): Hex-encoded Bitcoin scripts/txids in test fixtures. ai
source-diff encoded-string-file:test/transaction/input/multisigscripthash.js AI (source-diff): Hex-encoded Bitcoin scripts in test fixtures. ai
source-diff encoded-string-file:test/transaction/transaction.js AI (source-diff): Test fixtures with serialized Bitcoin transactions; expected for a Bitcoin library. ai
semgrep semgrep:base64-decode AI (semgrep): Base64 decoding of compact signatures is standard Bitcoin message signing/verification functionality, not a malicious payload. ai
semgrep semgrep:hex-decode AI (semgrep): Hex decoding is a fundamental operation in a Bitcoin library (address hashes, transaction data). These are not obfuscated payloads — they are core cryptographic functionality. ai

v11.5.1

2 findings
HIGH Long encoded string in modified file: test/transaction/transaction.js source-diff

Modified file contains 34 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.

v11.4.5

2 findings
HIGH Long encoded string in modified file: test/transaction/transaction.js source-diff

Modified file contains 34 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.

v8.25.10

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.
