Core engineering and protocols for Scoped Session Keys.
In fast-paced Web3 applications—such as blockchain games, automated DeFi arbitrage bots, or social dApps—prompting the user to sign a hardware wallet transaction for every action destroys user experience. Furthermore, using large post-quantum signatures for hundreds of micro-transactions introduces unnecessary overhead.
PQCSmartAccount generates ephemeral, lightweight session keys valid only for specific contract interactions (e.g., executing in-game moves or swapping tokens up to $500). The user authorizes the session once using their master ML-DSA key; the dApp then executes transactions silently using the scoped key until expiration.
