Core engineering and protocols for EVM PQC Precompiles.
Executing 256-point Number Theoretic Transforms and modular polynomial vector multiplications directly in standard EVM bytecode would consume tens of millions of gas per transaction—exceeding current Ethereum block gas limits. Efficient post-quantum verification requires native precompiled contracts written in compiled C++ or Rust and exposed at designated precompile addresses.
PQCEVM establishes rigorous benchmark profiles to price precompile invocations. By pricing ML-DSA-65 signature verification at approximately 55,000 gas, smart contracts can verify post-quantum signatures with costs comparable to classical ECDSA (3,000 gas) and pairing precompiles (45,000 gas), ensuring economic sustainability.
