Why wallet security is different
Funds move the moment a key is exposed
Irreversible by design
A stolen key or a swapped destination address means funds are gone for good. There is no chargeback in crypto.
The device is the threat
Wallets run on phones that may be rooted, jailbroken, or hooked, and targeted by malware that goes after wallet and exchange apps to intercept keys and approvals.
Users approve what they can't see
Overlays, fake screens, and blind-signing trick users into authorizing transactions that are not what they appear to be.
The vault model
Six layers orbit one signing core
Keys and approvals stay sealed at the center while each protection layer guards a different attack surface around them. Nothing reaches the core unchecked.
What the core protects
- Private keys and seed phrases stay sealed in hardware-backed storage.
- Every approval is bound and verified before a single token can move.
- The runtime is watched continuously for tampering.
On-device, hardware-agnostic, no key ever leaves the phone.
Sign what you see
See exactly what you sign
On a compromised device, an overlay or tampered approval can show one thing while another gets signed. Byteria binds the approved transaction to a device-attested signature and guards the signing screen, so what you see is what gets signed.
- Binds the approved recipient and amount to a verified signature
- Guards the signing screen against overlays and tampering
- Confirms what gets signed matches what was approved
Custody-grade
Protect keys, funds, and every transaction
Key & Seed Protection
Shields private keys, seed phrases, and signing secrets in hardware-backed storage (Secure Enclave, Android Keystore/StrongBox), hardened against extraction even on rooted or jailbroken devices.
Device Attestation & Build Integrity
Verifies the device and app with hardware attestation, Android KeyStore key attestation and Apple App Attest, plus build-signature baselines, so you can gate signing to genuine, untampered builds on real devices.
Overlay & Screen-Capture Protection
Blocks malicious overlays and unauthorized screen capture on the signing screen, so fake input screens and credential-stealing overlays can't sit on top of an approval.
Transaction Approval Integrity
Binds the approved transaction to a device-attested signature and guards the signing screen, so users approve exactly what gets signed, defending against blind-signing and UI tampering.
Malicious-App & Accessibility-Abuse Detection
Flags accessibility-service abuse, device-admin abuse, and known malicious apps and processes that target wallet and exchange apps.
Device & Runtime Integrity
Continuously checks for root, jailbreak, hooking, debuggers, and emulators to keep keys and approvals out of compromised environments.
Defense in depth
One key core, surrounded by protection
Every approval passes through a layered defense before a single token moves. The signing core stays hardened while each layer watches a different attack surface.
Keys & approvals
Transaction integrity
From request to a signature you can trust
Every transaction is checked end to end, so the approval a user sees is exactly the one that gets signed.
- 01
Request received
A dApp or in-app flow proposes a transaction with its destination, amount, and network.
- 02
Approval bound
The transaction's recipient and amount are bound into a device-attested signature request before it reaches the screen.
- 03
Screen integrity confirmed
Overlays and screen manipulation are blocked, so the details on display match the details being approved.
- 04
Signature authorized
Integrity verifiedThe user approves what they actually see, and the transaction is signed on-device without exposing the key.
Built for Web3
Security for every wallet
Non-Custodial Wallets
Keep self-custody keys safe on-device and protect signing from overlays, malware, and tampered approvals on compromised devices.
Exchange & CASP Apps
Harden trading and custody apps, meet rising security expectations, and protect user funds and credentials.
DeFi & dApp Browsers
Harden in-app browsers and WalletConnect sessions on compromised devices, with overlay and runtime protection around the signing flow.
Embedded & MPC Wallets
Add device-side hardening around embedded and MPC wallet SDKs for defense in depth.
Secure by design
Protection in three steps
01
Integrate the SDK
Add wallet security to your iOS, Android, or React Native app with minimal integration effort.
02
Protect keys & flows
Enable key protection, transaction-approval integrity, and threat detection tuned for wallet use cases.
03
Detect & respond
Receive real-time threat signals and enforce policy (warn, block, or step-up) before funds move.
Protect every transaction
Wallet security users can trust
Give your wallet the on-device defenses attackers don't expect, protecting keys, approvals, and funds without slowing the experience.
