Quantum computers will break the cryptography protecting every Ethereum wallet. QRAC moves your assets into a smart account secured by post-quantum signatures, on the existing EVM.
Every Ethereum wallet signs with ECDSA. A quantum computer running Shor's algorithm can recover your private key from your public key. Once exposed by your first transaction, your funds are one algorithm away from theft.
QRAC uses LMS/LM-OTS (RFC 8554), whose security relies only on hash function preimage resistance. No elliptic curves. No quantum vulnerability.
Your assets live inside a smart account. Every action needs a valid one-time post-quantum signature. No ECDSA key, whether leaked, stolen, or cracked, can authorize anything.
24 BIP-39 words create a Merkle tree of 1,024 one-time signing keys, independent of any Ethereum wallet.
A smart contract stores your post-quantum public key. It holds your ETH, tokens, and protocol positions.
Each action is signed in your browser with a fresh one-time key. Used keys are permanently consumed.
Any wallet delivers your signed action. The contract verifies the PQ signature before executing.
