Wallet-grade securityfor crypto apps
Protect wallets, exchanges, and dApp browsers: harden keys on-device, guard the approval screen from overlays, and keep signing on attested, uncompromised devices, with no compromise on UX.

On-device keys
Keys never leave the device
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.
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.
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.
FAQ
Frequently asked questions
Do you store or have access to user keys?
No. Protection runs on-device; keys never leave the device or pass through Byteria. We harden where they already live.
Do I need a Secure Enclave or special hardware?
No. Protection is hardware-agnostic and works across devices, with extra strength where secure hardware (Secure Enclave, StrongBox/TEE) is available.
How is this different from a regular RASP SDK?
It applies RASP to the wallet threat model: hardware-backed key protection, device attestation for signing, signing-screen and overlay integrity, and malicious-app detection, on top of runtime protection.
What platforms are supported?
iOS, Android, and React Native.
Will it slow down transactions or the app?
It's lightweight and built for mobile; protection runs without a noticeable impact on UX or transaction speed.
