Hybrid Accounts for Solana

Quantum computers are becoming a long-term security risk for digital asset infrastructure, especially on Solana, where wallet addresses are directly linked to Ed25519 public keys. Instead of requiring a disruptive full migration to post-quantum cryptography, our hybrid account model enables a practical transition path that preserves the speed and usability required for real-time payment systems.

We are building a native post-quantum extension for Solana that introduces Falcon (FN-DSA) quantum-secure vaults alongside standard Ed25519 payment wallets. The system enables stablecoins, custodial accounts, treasury wallets, and other long-lived digital assets to be securely stored in PQC vaults while continuing to use fast classical wallets for high-throughput payments, DeFi activity, and everyday transactions.
