Summary

This repository contains test files documenting Substrate/Polkadot blockchain cryptographic patterns including Ed25519, sr25519, and ECDSA signatures. All 48 findings are located in test files with no production cryptographic implementations detected. The repository appears to be a scanner or documentation tool rather than a cryptographic application, resulting in minimal direct quantum risk.
