Hardening Web3: Implementing ML-DSA (Dilithium) Signers in EVM Smart Contract Wallets

Don't wait for the L1 to fork. You can achieve NIST-ready security today using Smart Contract Wallets (SCW) as an abstraction layer for Post-Quantum (PQ) keys.
​Technical Deep Dive:
​The 3-in-1 Solver: 1. SCW Layer: Removes seed phrase vulnerability (No more 24-word single points of failure).

  1. PQ-Signer: The primary owner of the SCW is an ML-DSA (FIPS 204) key pair.
  2. Circuit Breaker: Utilizing a "Quantum DeFi Wrapper" to pause high-value outflows if signature anomalies are detected. ​Gas Optimization: Address the elephant in the room—signature size. Explain how the Lattice L1/L2 hybrid DAG allows for parallelized signature verification to mitigate the 4-10x computational overhead typical of Lattice-based schemes. ​Code Snippet Concept: Show a pseudocode implementation of a verifyPQSignature function within a Solidity-based SCW.
