Thanks for sharing this—really valuable work! At Quranium, a Layer 1 blockchain protocol optimized for post-quantum security, AI integration, and EVM compatibility, we're working on similar challenges and recently rolled out a post-quantum-ready crypto wallet using SLH-DSA and ML-KEM, both NIST-finalized algorithms. We’ve focused heavily on real-world implementation: integrating split-key architecture for transaction signing and encrypted backups across chains like Bitcoin, Ethereum, and Solana.

Would love to hear how you’ve approached performance trade-offs, especially around key sizes and hybrid models. Also curious if you explored any post-quantum options for recovery flows or user-facing backup systems.

Great to see more people tackling this beyond government or financial sectors.
