Web3 Security

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.

Why wallet security is different

Funds move the moment a key is exposed

  1. Irreversible by design

    A stolen key or a swapped destination address means funds are gone for good. There is no chargeback in crypto.

  2. 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.

  3. 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.

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.
Built for Web3

Security for every wallet

  1. Non-Custodial Wallets

    Keep self-custody keys safe on-device and protect signing from overlays, malware, and tampered approvals on compromised devices.

  2. Exchange & CASP Apps

    Harden trading and custody apps, meet rising security expectations, and protect user funds and credentials.

  3. DeFi & dApp Browsers

    Harden in-app browsers and WalletConnect sessions on compromised devices, with overlay and runtime protection around the signing flow.

  4. Embedded & MPC Wallets

    Add device-side hardening around embedded and MPC wallet SDKs for defense in depth.

Secure by design

Protection in three steps

  1. 01

    Integrate the SDK

    Add wallet security to your iOS, Android, or React Native app with minimal integration effort.

  2. 02

    Protect keys & flows

    Enable key protection, transaction-approval integrity, and threat detection tuned for wallet use cases.

  3. 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.

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.
