VEYRNOX · Trezor iOS Alternative
The Trezor iOS alternative — hardware-bound self-custody, mobile-native
Trezor is an excellent piece of hardware, but on iPhone the experience is a compromise. VEYRNOX is the mobile-native alternative: hardware-bound signing through Apple's Secure Enclave with no extra device to carry — and if you already own a Trezor, VEYRNOX pairs with it for cold storage.
Trezor's iOS limitations
- Trezor Suite on iOS is limited in scope compared to desktop.
- Signing UX on iPhone is constrained — historically Trezor has focused on desktop and Android for full device interaction.
- You still need to carry, charge or connect, and physically confirm on a second device.
How VEYRNOX gets you comparable hardware-bound security on iPhone
- Secure Enclave signing. Keys live inside Apple's dedicated security chip. Signing operations happen inside the enclave; cleartext keys never enter app memory.
- Shamir Secret Sharing. The seed is split into KEK-encrypted shards across device (Secure Enclave) and your personal cloud (iCloud, OneDrive, Google Drive, Dropbox, etc.). No Veyrnox-held shard.
- Biometric + PIN gating. Every signing operation requires Face ID / Touch ID and PIN.
- RASP. Root / jailbreak / debugger detection blocks signing on compromised devices.
- Coercion Resistance (Safety Plus). Decoy wallet under duress — something no consumer hardware wallet ships natively.
Already own a Trezor? Pair it with VEYRNOX for cold storage
You don't have to pick. VEYRNOX pairs with Trezor so you can keep long-term holdings in cold storage on the hardware device and use VEYRNOX for daily mobile activity — a common two-wallet posture with a single mobile interface.

| Hardware-bound signing | Yes (Secure Enclave) | Limited on iPhone |
| Mobile-first UX | Yes | No |
| Cold storage | Yes — pair with Trezor | Yes — native |
| Coercion resistance (decoy wallet) | Yes (Safety Plus) | No |
| Seed phrase in UI | No | Yes |
| Cost to start | $0 | $79+ hardware |
How it works
A Trezor stores your private keys inside a dedicated hardware chip and signs transactions on the device itself, gated by a PIN and physical button confirmation. That model is the gold standard for cold storage — and it is exactly the model Veyrnox reproduces on iPhone. During setup Veyrnox generates your keypairs inside the Secure Enclave, Apple's dedicated hardware security chip. The private keys never leave the enclave in cleartext, iOS itself cannot extract them, and no Veyrnox process ever holds them in memory. When you send BTC, ETH, SOL, or any supported asset, the app assembles the transaction, hands it to the enclave for signing behind a Face ID or Touch ID prompt, and broadcasts the signed result. The confirmation screen shows the recipient, the amount, and the network fee before you approve — the same "verify on-device before signing" discipline a Trezor gives you, without a second device to plug in.
Fees
Veyrnox charges $0 for wallet operations on the free plan. Every-day self-custody — send, receive, portfolio, WalletConnect dApp sessions — costs nothing. The only cost when moving funds is the underlying network fee, which is set by the chain (miner fee on Bitcoin, gas on Ethereum, network fee on Solana), denominated in the native asset, and shown on the confirmation screen before you approve. Compare that to a Trezor, which requires paying $79 or more up-front for the hardware device itself before you sign a single transaction. Advanced Veyrnox features — the duress wallet on Safety Plus — sit on a paid tier at $5.99 per month, but everyday self-custody stays free.
Supported networks — daily-driver hot wallet plus Trezor cold storage
Veyrnox is a full multi-chain wallet: BTC, ETH, SOL, USDC and USDT across Ethereum, Polygon, Arbitrum, and Solana, plus MATIC, ARB, OP, AVAX, and BNB on their native chains. All of that lives in one iOS app with a single 8-digit PIN and Face ID. If you already own a Trezor, you do not have to choose. The recommended posture for security-conscious users is Veyrnox on iPhone as the daily-driver hot wallet — the one you actually carry, tap-to-open, and use for DEX swaps, stablecoin transfers, and small BTC amounts — and a Trezor as cold storage for long-term holdings that rarely move. Veyrnox pairs with Trezor so you can manage both from the same mobile interface, without maintaining two separate address books, two histories, and two mental models. See the full multi-chain wallet page for the current supported-chain list.
Compared to competitors
Trezor Suite on iOS is a compromise by design. Trezor's full device-interaction experience has historically lived on desktop and Android, and the iOS Suite exposes a narrower slice of functionality. You still need to carry the hardware device, keep it charged or connected, and physically confirm every operation on the device screen. That is a reasonable trade for cold storage, but a bad trade for the wallet you actually use to move money on the go. Ledger Live has similar iOS constraints and the same second-device tax. Software-only iPhone wallets like Trust Wallet, MetaMask, Blue Wallet, Muun, and Phantom solve the mobility problem but drop the hardware-bound signing model — signing keys live in software and recovery is a 12-word phrase. Veyrnox targets the missing middle: hardware-bound signing on iPhone through the Secure Enclave, mobile-first UX, no second device, no seed phrase in the UI, and native pairing with a Trezor when you want cold storage in addition. Coinbase Wallet and Zengo have their own approaches — Zengo uses MPC without a seed phrase, and Coinbase Wallet still exposes one — but neither treats the iPhone Secure Enclave as the primary signing surface the way Veyrnox does.
Security model
Every signing operation in Veyrnox happens inside the Secure Enclave, gated by Face ID or Touch ID and the 8-digit PIN. The app cannot construct a signed transaction without an explicit biometric approval on the confirmation screen. Recovery uses Shamir Secret Sharing: the material needed to reconstruct your keys is split into KEK-encrypted shards across the device (Secure Enclave) and your personal cloud (iCloud, OneDrive, Google Drive, Dropbox, etc.), and reconstitution requires both. Veyrnox holds no shard — the company cannot recover your wallet on your behalf and cannot be compelled to hand it over. Runtime Application Self-Protection detects rooted or jailbroken devices, active debuggers, and instrumentation frameworks, and blocks signing on compromised phones. Coercion Resistance — a duress wallet that unlocks a plausible decoy under a different PIN — sits on the Safety Plus tier and covers the physical-threat case no consumer hardware wallet ships natively. See Duress wallet for the full model. For deeper detail on cryptography and threat model see Security at Veyrnox, No seed phrase wallet, and Shamir wallet.
Frequently asked questions
Do I need to buy a Trezor to use Veyrnox?
No. Veyrnox delivers hardware-bound signing on iPhone through the Secure Enclave, with no extra device to buy, carry, or charge. If you already own a Trezor, Veyrnox pairs with it for cold storage — but a Trezor is not required.
Why is Trezor limited on iOS?
Trezor Suite on iOS is narrower in scope than the desktop app, and Trezor has historically focused its full device-interaction experience on desktop and Android. On iPhone you still need to carry, charge or connect, and physically confirm on the hardware device.
Is signing in the Secure Enclave really comparable to a hardware wallet?
The Secure Enclave is a dedicated hardware security chip that iOS itself cannot extract keys from. Signing operations happen inside the enclave; cleartext keys never enter app memory. That is the same custody principle a Trezor implements — with the phone you already carry and no cable to plug in.
Can I use Veyrnox and Trezor together?
Yes. A common posture is Veyrnox on iPhone as the daily-driver hot wallet and a Trezor for long-term cold storage. Veyrnox pairs with Trezor so you can manage both from the same mobile interface.
What does Veyrnox cost compared to a Trezor?
Veyrnox charges $0 for wallet operations on the free plan. A Trezor device costs $79 or more upfront. Advanced features like the duress wallet live on the paid Safety Plus tier at $5.99 per month, but everyday self-custody stays on the free plan.
Does Veyrnox have a seed phrase like a Trezor?
No. Trezor gives you a 12- or 24-word seed phrase to write down. Veyrnox has no seed-phrase field in the UI — recovery is an 8-digit PIN plus a Shamir shard in your personal cloud (iCloud, OneDrive, Google Drive, Dropbox, etc.) (Safety Plus tier), with signing keys bound to the Secure Enclave.
What about coercion — the wrench-attack scenario?
Veyrnox Safety Plus ships a duress wallet — under a coercion PIN the app unlocks a decoy wallet with plausible balances instead of the real one. No consumer hardware wallet ships coercion resistance natively.
Is Android supported?
iOS today, Android coming soon.
Add AI Security Protection ($19.99/mo, coming soon)
Hardware-bound signing — whether via a Trezor over USB-C or via the Secure Enclave on iPhone — prevents key theft. It does not prevent you from approving a transaction to a drainer contract, a spoofed dApp, or a phishing frontend that looks identical to Uniswap. AI Security Protection — $19.99/mo, coming soon is the Veyrnox tier that adds pre-sign threat intelligence on top of the hardware-bound signing layer. All ten features are shipped: Address Threat Screening (TIP edge function screens recipients pre-sign), Phishing Site Detection (curated blocklist, not an ML classifier), Risk Scoring (nine-signal rule-based scorer, deterministic), Token Approval Review, Approval Monitor (periodic polling), AI Risk Notes, Personal AI Advisor (on-demand chat interface), Drainer Detection (local heuristics), Transaction Explanation, and Portfolio Q&A. See Plans & pricing for the full AI Security Protection tier — an AI Security add-on to the Veyrnox stack.
