I scanned 200 blockchain npm packages for quantum-vulnerable cryptography. Here's what I found.

Short summary

Analysis of 200 blockchain npm packages revealed widespread quantum-vulnerable cryptography (ECDSA-only signature schemes). The author released quantum-audit, a free open-source tool to scan dependencies for these vulnerabilities. Roadmap includes Solidity contract scanning, migration guidance to post-quantum alternatives, and integration with Chain Audit for broader risk intelligence.

  • •Scanned 200 blockchain packages; found pervasive quantum-vulnerable ECDSA-only signatures
  • •Released quantum-audit: free open-source npm tool to audit your project dependencies
  • •Roadmap: Solidity scanning, per-finding migration guidance, Chain Audit integration

Generated with AI, which can make mistakes.
