Veyrnox is a self-custody crypto wallet built for people who take their own security seriously. Your seed phrase is your identity. Keys never leave the device. There is no server-side custody, no email login, no backdoor — and no way for anyone, including us, to move your funds without your PIN and your device in hand. SUPPORTED ASSETS Send, receive, and hold ten assets across eight networks from a single seed: • Ethereum (ETH), Polygon (MATIC), Arbitrum (ARB), Optimism (OP), Avalanche (AVAX), BNB Smart Chain (BNB) • Bitcoin (BTC) with native SegWit • Solana (SOL) • USDC and USDT stablecoins One seed derives every account — one address for the EVM chains, dedicated addresses for Bitcoin and Solana. BUY CRYPTO IN-APP Fund your wallet directly from the app with card, bank transfer, or Apple Pay via Transak. Rates and fees are shown before you commit; your crypto lands straight in your own wallet, never a custodial account. STEP-BY-STEP SEND WIZARD The redesigned Send flow walks you through one decision at a time — recipient, amount, review, confirm — with plain-language fee explanations, spend-limit protection, and a clear celebration when the transaction broadcasts. WALLETCONNECT WITH QR PAIRING Connect to any WalletConnect-enabled dApp by scanning a QR code or pasting a link. Every session, signature, and token approval is broken down in plain language before you sign, including the exact ERC-20 amount and recipient — so you know what you are approving. AI SECURITY ADVISOR WITH LIVE THREAT INTEL An on-device security assistant answers your questions about scams, phishing, seed-phrase hygiene, and safe signing. It is fed a weekly digest of live threat intelligence — NVD vendor advisories, known bad addresses, and known-bad token contracts — so its warnings reflect what is actually happening in the ecosystem this week, not last year. HARDWARE-BACKED ENCRYPTION Your vault is protected with AES-256-GCM and an Argon2id key derivation designed for modern mobile hardware. On supported devices, an additional hardware key is bound to the Secure Enclave, so the vault cannot be unlocked on any other device even if the encrypted blob is copied. FAST, PRIVATE UNLOCK Unlock with a glance. Face ID prompts automatically on the lock screen, with a fast-path that keeps unlock times under a second on modern iPhones — without weakening the crypto underneath. COERCION-RESISTANT DESIGN Veyrnox is built for the reality that someone might force you to open the app. A deniable mode shows a plausible empty wallet. A duress PIN opens a decoy vault. A panic gesture wipes local state cleanly. In any of these modes, the app makes zero backend calls and leaves no residue that a later inspection can find. PERSONAL BACKUP (2-OF-3 RECOVERY) For long-term storage, split your recovery into three shards using Shamir's Secret Sharing. Any two shards restore the wallet; one alone reveals nothing. Store them across devices, safes, or trusted contacts. REAL-TIME PRICES Live 24-hour price movement on every asset in your list, sourced from public price feeds. No pop-ups, no ads, no upsells in the trading path. OPTIONAL SUBSCRIPTIONS Safety Plus ($5.99/mo, $49.99/yr): Personal Backup (Shamir 2-of-3), duress PIN, hidden wallets, panic wipe. AI Security Protection ($19.99/mo, $159.99/yr): Safety Plus plus Live Vigil, a TIP-backed AI security chat. Both include a 14-day free trial if eligible. PRIVACY AND DATA Anonymous usage events are transmitted only if you opt in on first launch, and can be turned off at any time in Settings → Privacy. Nothing you type into the app — no seed, no PIN, no address book — ever leaves your device. WHO IT IS FOR Long-term self-custody holders, DeFi users tired of confusing signing prompts, and anyone who wants a wallet that treats coercion and phishing as the real threats — not the exception.
