Meet Qozmo Quantum

A separate smart account. One stable address. A fresh signing key for every operation.

A separate kind of account

Qozmo Quantum is an ERC-4337 smart account authorized by WOTS / Keccak-256 hash-based signatures. It has its own recovery phrase, encrypted vault, address, and signing history. It does not convert your everyday EVM account or protect assets that remain in that ECDSA account.

Why one-time keys matter

  1. 1

    Prepare an operation

    Qozmo builds the requested transfer and estimates its network requirements.

  2. 2

    Review and confirm

    You review the account, recipient, token, amount, network, and maximum fee, then confirm with the quantum password.

  3. 3

    Sign and record

    A one-time key signs the operation and its successor commitment. The full signed bytes are saved before submission.

  4. 4

    Verify execution

    The operation is relayed to EntryPoint. Qozmo checks execution evidence separately from the key’s retirement.

Your signing journal

A one-time key must not authorize two different messages. Qozmo keeps a write-ahead journal, serializes signing across same-origin tabs, and blocks conflicting signatures. If submission becomes uncertain, the journal retains exactly what was signed.
