The World's First
Quantum-Secured
Privacy Terminal
Shield your crypto with zero-knowledge proofs and quantum-generated keys. Send, receive, and store tokens privately on Ethereum. Invisible on-chain.
Your Crypto Isn't As Private As You Think
Every transaction you make on Ethereum is permanently visible. Your wallet balance, who you pay, who pays you, how much, and when. All public. Chain analytics firms track, label, and sell this data.
Regular wallets offer zero privacy. Even "privacy coins" have been cracked by sophisticated analysis. And the keys protecting your wallet? Generated by algorithms that quantum computers will eventually break.
Fully Transparent Transactions
Every ETH and token transfer is visible on Etherscan. Anyone can track your complete financial history.
Linked Wallet Identity
Once your wallet is connected to your identity (via an exchange, ENS, or NFT), every past and future transaction is linked to you.
Pseudorandom Key Generation
Standard wallets use algorithmic randomness (PRNG) for key generation. Quantum computers will eventually predict these patterns.
How QShield Works
Three layers of protection that no other wallet combines
Quantum Key Generation
Your wallet keys are generated using real quantum entropy from Qubit's quantum random number generators. Hardware devices harvest true randomness from quantum mechanical processes. This entropy is XOR-mixed with your device's CSPRNG, ensuring keys that are at least as strong as the strongest source. No algorithm. No patterns. Unpredictable by any computer, classical or quantum.
RAILGUN Shielding
Your tokens are shielded using RAILGUN Protocol, the leading on-chain privacy system built on Groth16 zero-knowledge proofs. Once shielded, your balance is encrypted inside a smart contract. Transfers happen privately: the sender, receiver, amount, and token are all hidden. Even the gas is paid by third-party broadcasters so there's no link to your public wallet.
Proof of Innocence
Every private transaction automatically generates a cryptographic Proof of Innocence, providing mathematical evidence that your funds don't originate from sanctioned or illicit sources. This means full privacy WITH regulatory compliance. No other privacy wallet offers this by default.
Your Money, Your Privacy
A complete journey from public to private, with full control at every step
Connect Your Wallet
Connect any Ethereum wallet (MetaMask, WalletConnect). This is your public funding source.
Create Your Shielded Wallet
QShield generates a private RAILGUN wallet using quantum entropy. Your keys are truly random, generated from quantum physics, not algorithms.
Shield Your Tokens
Move ETH, USDC, DAI, or any ERC-20 token from your public wallet into RAILGUN's privacy pool. Your tokens are now encrypted on-chain.
1-hour standby period for maximum privacy
Transact Privately
Send tokens to any RAILGUN address. Zero-knowledge proofs ensure nobody can see who sent what to whom. Not even us.
Unshield When Ready
When you need tokens in a public wallet, unshield them to any Ethereum address. A 0.25% protocol fee applies.

Built for Real Privacy Users
Professional-grade features for those who take privacy seriously
Multi-Wallet System
Create multiple independent shielded wallets: Personal, Business, Savings. Each has its own quantum-generated keys and password. Transfer privately between them with zero on-chain link.
25+ Tokens Supported
Shield and send ETH, USDC, USDT, DAI, WBTC, WETH, LINK, UNI, AAVE, and 15+ more tokens. Add any custom ERC-20 by pasting the contract address.
QShield Transfer
Send tokens between your own shielded wallets with one click. The blockchain sees a standard private transfer with no way to know both wallets are yours.
Real-Time Balance Scanning
RAILGUN's Merkle tree scanner finds your shielded tokens across the entire blockchain. Balances update automatically with no manual refresh needed.
Broadcaster Network
Private transactions are submitted through RAILGUN's decentralized broadcaster network. Broadcasters pay the gas so there's no link between your public wallet and private activity.
Quantum Entropy Proof
Every wallet comes with verifiable proof that its keys were generated using quantum hardware. Not just pseudorandom, but provably random.
QShield vs. The Competition
No other wallet combines quantum-secured keys, zero-knowledge privacy, multi-wallet management, and regulatory compliance.

Security You Can Verify
Built on proven cryptographic foundations with multiple layers of protection
Quantum Entropy Source
Keys generated from Qubit's quantum random number generators, certified hardware that produces true randomness from quantum vacuum fluctuations. XOR-mixed with your device's cryptographic RNG for defense-in-depth.
Client-Side Encryption
Your mnemonic seed phrase is encrypted with AES-256-GCM before storage. The encryption key is derived from your password via PBKDF2-SHA256 with 600,000 iterations. Keys never leave your browser.
Zero Server Knowledge
QShield has no backend database. No accounts. No registration. Your encrypted wallet lives in your browser's IndexedDB. We literally cannot access your funds, even if compelled to.
Open Protocol
Built on RAILGUN, an open-source, audited smart contract system with $78M+ TVL. The RAILGUN contract (0xfa70...4b9) has been live on Ethereum since 2022 with zero exploits.
Under the Hood
