The first ERC-4337 smart account secured by CCHS — Chain-Cached Hypertree Signatures. SHA-256 based, quantum-resistant, and deployed at the same deterministic address on every EVM chain.
Three steps to a quantum-resistant smart account that lives at the same address on every EVM chain.
Classical ECDSA is vulnerable to Shor's algorithm. Once large-scale quantum computers arrive, every Ethereum wallet is at risk. RAMPART solves this today.
CCHS relies only on SHA-256 collision resistance. No algebraic structure — no quantum speedup beyond Grover's algorithm, which only halves the security level, leaving SHA-256 safe.
Traditional smart accounts use secp256k1. Shor's algorithm can break elliptic curve discrete log in polynomial time on a large enough quantum computer. CCHS avoids this entirely.
Migrating after a quantum computer is built will be too late. RAMPART protects your assets now — while also giving you ERC-4337 gas sponsorship, batching, and social recovery.
