ERC-4337 Account Abstraction is the Ethereum standard that makes BMIC’s quantum security possible at the wallet level. Without ERC-4337, adding CRYSTALS-Kyber and Dilithium to Ethereum wallets would require a hard fork of the entire protocol. With ERC-4337, BMIC implements full NIST 2024 post-quantum cryptography today, on mainnet, without any protocol changes. Here is exactly how it works.
Ethereum’s transaction validation is hardcoded to verify ECDSA secp256k1 signatures at the protocol level. Every transaction on Ethereum must be signed with ECDSA — the protocol rejects any other signature format. This means no wallet, regardless of its UI or features, can use a different signing algorithm without Ethereum itself being changed. Changing Ethereum’s core signing algorithm would require a hard fork with consensus from the entire ecosystem. That is years away and uncertain.
ERC-4337 introduces a parallel transaction system called User Operations. Instead of Ethereum directly validating your signature, your transaction goes through a smart contract called an Account Contract. The Account Contract has its own validation logic — and that logic can implement any cryptographic algorithm you choose. BMIC’s Account Contract validates CRYSTALS-Dilithium signatures instead of ECDSA. Ethereum’s core protocol never sees a non-ECDSA signature — it only sees the Account Contract calling itself. The quantum-safe validation happens inside the smart contract layer, completely compatible with Ethereum today.
Standard Ethereum: When you send a transaction, your public key is permanently recorded on-chain. BMIC with ERC-4337: Your public key is stored inside the Account Contract’s private state. The Dilithium verification happens inside the contract. No public key ever appears in calldata or transaction data. Harvest-now-decrypt-later attacks cannot harvest what is never published. The quantum attacker has no public key to run Shor’s algorithm against. This is the architectural innovation that makes BMIC genuinely quantum-resistant rather than just quantum-resistant-in-theory.
| Component | Standard Ethereum | BMIC ERC-4337 |
|---|---|---|
| Transaction type | EOA transaction | UserOperation via EntryPoint |
| Signature validation | ECDSA in protocol | CRYSTALS-Dilithium in smart contract |
| Public key on-chain | Yes — every transaction | Never — stored in contract state |
| Key encapsulation | None | CRYSTALS-Kyber ML-KEM-768 |
| Backward compatible | N/A | Yes — hybrid ECDSA+Dilithium |
| Requires Ethereum fork | N/A | No — works on mainnet today |
BMIC implements hybrid signing — every transaction is signed with both ECDSA and CRYSTALS-Dilithium simultaneously. This means: full compatibility with all existing Ethereum dApps, exchanges, and infrastructure (ECDSA); full quantum resistance (Dilithium); no breaking changes for any integration; and a clean migration path as the ecosystem evolves. When Ethereum eventually adopts native PQC, BMIC wallets are already fully compliant.
What is ERC-4337?
Ethereum’s Account Abstraction standard — allows smart contracts to act as wallets with custom validation logic. BMIC uses this to implement CRYSTALS-Dilithium signing without needing an Ethereum protocol change.
How does ERC-4337 make BMIC quantum safe?
BMIC’s Account Contract validates Dilithium signatures instead of ECDSA. Ethereum’s protocol only sees the contract calling itself — fully compatible today. Public keys are never exposed on-chain.
Does BMIC require Ethereum to hard fork?
No. ERC-4337 is already deployed on Ethereum mainnet. BMIC uses the existing infrastructure. No protocol changes required.
Is BMIC’s ERC-4337 implementation audited?
Yes. BMIC’s smart contracts have been independently audited. The Account Contract implementing Dilithium validation has no critical vulnerabilities found.
