QNTMEX Wallet: Crypto & Web3

QNTMEX LTD

About this app

Own your wealth completely. QNTMEX is a privacy focused self-custody cryptocurrency wallet engineered for investors who refuse to compromise on security, privacy, or control. Across five of the world's most significant blockchain networks, your assets remain in your hands, under your authority, at all times.
No intermediaries. No custodians. No third-party access. Just you and your assets.

🔗 FIVE CHAINS. ONE WALLET.

👤 SEND CRYPTO BY USERNAME
─────────────────────
QNTMEX redefines how digital assets move between people. When setting up your account, you create your own unique username — chosen entirely by you, your identity within the QNTMEX network.
That username is how others send to you. And how you send to them.
Type a username. Enter an amount. Confirm. Done.
No wallet addresses to copy. No character strings to verify. No risk of sending to the wrong destination. Username-based transfers execute instantly, incur no on-chain fees, and keep your wallet address completely concealed from the recipient.
Share your username like a phone number. Receive payments from clients, settle balances with contacts, or move funds between your own accounts — each with its own self-chosen username.
This is how crypto should feel. Fast, human, and precise.

─────────────────────
🔑 RECOVERY & BACKUP
─────────────────────
Secured by a BIP-39 compliant 12-word recovery phrase generated entirely on-device. No copy held by QNTMEX. The sole mechanism for restoring access after device loss or replacement. Preserve it offline. Guard it absolutely.
─────────────────────
🔒 ZERO-CUSTODY SECURITY
─────────────────────
No assets held. No keys stored. No access granted — to anyone, including QNTMEX.

Private keys encrypted and retained exclusively on-device
AES-256 PIN encryption with optional biometric unlock
Your chosen username keeps your on-chain address private
BIP-39 compliant for cross-platform portability

Your assets are yours alone. Not ours. Not anyone else's.
Your keys. Your username. Your assets. Your sovereignty.

⚠️ DISCLOSURES
