Summary
Togoder Security scanned the npm package @solana/assertions@5.0.0 on Oct 4, 2026. An AI review of 5 source files produced 2 low severity findings. No malicious behavior, install-time payloads, credential theft or exfiltration were identified.
Findings 2
Environment capability detection
NPS-5E00BF171C14
The code performs runtime capability checks on the WebCrypto API (crypto.getRandomValues, crypto.subtle.digest/generateKey/exportKey/sign/verify) and secure context status. This is standard defensive feature detection for a crypto library, not credential harvesting or environment enumeration.
Cached async state
NPS-6DE64ACD25F6
isEd25519CurveSupported caches a Promise and later reassigns it to a boolean. The mixed Promise/boolean type is slightly unusual but functionally sound and not a security concern.
Files reviewed
| File | Verdict | What the reviewer saw |
|---|---|---|
| dist/index.browser.cjs | safe | The module only performs benign WebCrypto capability assertions and exports helper guards, with no exfiltration, dynamic execution, process spawning, or file system access. |
| dist/index.browser.mjs | safe | No malicious patterns detected; the code only performs legitimate WebCrypto capability checks for a Solana SDK. |
| dist/index.native.mjs | safe | No malicious patterns detected; the code only provides capability assertions for the Web Crypto API without any exfiltration, obfuscation, or dynamic execution. |
| dist/index.node.cjs | safe | No malicious patterns detected; the file contains only legitimate capability checks for the Web Crypto API used by @solana/errors. |
| dist/index.node.mjs | safe | No malicious patterns detected; the code only performs capability checks for Web Crypto APIs used in Solana cryptography. |
