Quantum-Resistant ERC-20 with Dual-Signature Authorization and Owner-Sovereign Recovery

This technology is protected by preliminary U.S. and European patent filings.

1. Introduction

Lemnicoin is a quantum-resistant ERC-20 digital asset platform designed to eliminate legacy wallet-based theft risk while preserving full compatibility with the Ethereum ecosystem. It introduces dual post-quantum authorization, off-chain attestation enforcement, and owner-sovereign recovery mechanisms without requiring new blockchains or forks.

2. Problem Overview

Traditional ERC-20 tokens rely on ECDSA wallet signatures. If a private key is stolen, assets can typically be drained instantly. If a wallet is lost, recovery is often centralized or impossible.

Lemnicoin addresses:

  • Quantum-era cryptographic risk
  • Single-key wallet theft
  • Replay and cross-chain attacks
  • Custodial bypass vulnerabilities
  • Chain compromise scenarios
  • Lost-wallet-key recovery

3. Architecture Overview

Lemnicoin enforces a three-layer authorization model:

  • Layer A — User Intent: Dual post-quantum signatures (LAIP + Dilithium)
  • Layer B — Attestation: Falcon-based verification and attestation
  • Layer C — On-Chain Enforcement: Smart contract validation of attestation + key binding + nonce + domain constraints

4. Cryptographic Binding Model

All approvals and transfers are bound to:

  • chainId
  • verifying contract
  • user
  • recipient / spender
  • amount
  • quantum input hash
  • nonce
  • deadline

This prevents replay, cross-domain reuse, and cross-chain portability.

5. Quantum Key Registration

Keys are bound through a challenge-response process that prevents injection or replay.

6. Enforced Transfer Policy

Standard ERC-20 transfer paths are disabled for normal users. Only quantum-authorized pathways are permitted.

7. Vault Isolation Model

Post-quantum keys are handled in a dedicated cross-origin vault with strict security headers and memory-only secret handling.

8. Owner-Sovereign Escape Mechanism

If a source chain becomes compromised, users may construct a deterministic escape claim signed with LAIP keys, verified on Ethereum L1 for canonical minting.

9. Theft-Proof & Lost-Wallet-Key-Proof Recovery

Possession of a legacy wallet is insufficient to move LEMNI. All transfers require dual post-quantum signatures derived from the user’s seed phrase.

If a wallet is stolen or drained of gas tokens:

  1. User creates a new wallet
  2. User reconnects with original seed phrase
  3. Quantum keys are deterministically regenerated
  4. User authorizes transfer from original wallet
  5. Fees are paid by new wallet

This design renders Lemnicoin theft-proof against legacy wallet compromise and enables deterministic recovery when the user retains their seed phrase.

10. Conclusion

Lemnicoin introduces quantum-resistant authorization, enforced dual-signature validation, attested on-chain enforcement, vault isolation, and owner-sovereign recovery — all within the existing ERC-20 ecosystem.

It eliminates single-key wallet theft risk while preserving decentralization, compatibility, and user sovereignty.
