Our AI source review of @ethereumjs/tx@5.4.0 found no malicious code: no install-time payloads, credential theft, exfiltration, obfuscated loaders or backdoors.
Does @ethereumjs/tx contain malware?
No malware was identified in @ethereumjs/tx@5.4.0 when Togoder Security scanned it on Oct 4, 2026. A new version can still introduce malicious code, so scan the exact versions in your lockfile.
How was @ethereumjs/tx checked?
Togoder Security downloaded the published npm package and had an AI model read its 51 source files, looking for install scripts, credential access, network exfiltration, obfuscation, backdoors and crypto-wallet theft. The results are cached by file hash and shown here.
How do I scan @ethereumjs/tx together with the rest of my dependencies?
Upload your lockfile at https://security.togoder.click/scan or call the API documented at https://security.togoder.click/api-docs. Files that have already been scanned, like the ones in @ethereumjs/tx@5.4.0, cost nothing.
