Overview
opeq is a wallet designed to protect funds from quantum computing threats. It uses Winternitz one-time signatures arranged in a Merkle tree, built on SHA-256 hashing rather than elliptic-curve cryptography. The wallet works across Solana and EVM networks (Ethereum, Base, Arbitrum, Robinhood Chain, Elysium) while maintaining the same address across all platforms. Recovery uses standard BIP39 words, and the wallet supports optional multisig, token bridging, and integration with decentralized applications like Jupiter and Uniswap. opeq is currently available as a Chrome extension or USB drive for Windows, with a devnet test version available.
Feature summary
- Hash-based signatures resistant to Shor's algorithm

- Optional multisig vault for shared control
- Bridge SOL, ETH, HYPE and USDC between networks
- One-time key system with 1024 keys per tree
- No private key on-chain for wallet address
- 448-byte signature size with NIST category 1 quantum security

Q&A
- How does opeq protect against quantum computers?
- opeq uses hash-based signatures built on SHA-256 hashing rather than elliptic-curve cryptography. Quantum computers running Shor's algorithm can break Ed25519 and secp256k1, but Grover's algorithm only halves the effective strength of hash functions, which opeq's long hashes absorb. The signature scheme is WOTS+ (Winternitz one-time signatures) arranged in a Merkle tree, following NIST's SLH-DSA standard.
- What happens when all 1024 keys in a tree are used?
- After signing 688 transactions with one key tree, the wallet performs a rekey in one click to move to a fresh tree. The address, balances and token accounts never change, and recovery words remain valid after any number of rekeys.
- What protection does opeq provide against key reuse attacks?
- opeq is built on the principle of never reusing a key. The next key is reserved and saved before anything is signed, a browser lock prevents two tabs from signing with the same wallet, the wallet record is authenticated with your password, failed transactions have their keys burned, and every signature includes an expiry slot checked on-chain.
- Can opeq wallets work in multisig?
- Yes, wallets can team up in an optional multisig vault. A shared vault moves funds only after several opeq wallets approve, for example 2 of 3. Every approval is a one-time hash-based signature, and multisig is available on Solana and all five EVM networks.
