🌐
Multi-Chain Support
Switch between multiple EVM-compatible networks from a single interface. Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche, and zkSync Era — plus the ability to add any custom EVM network by entering a Chain ID, RPC URL, and native token symbol.

📥
Wallet Import & Export
Import wallets via 12 or 24-word BIP-39 mnemonic phrases (standard m/44'/60'/0'/0/0 derivation path) or raw private keys. Supports bulk import and wallet group management.

🔄
Multi-RPC Fallback
Configure multiple RPC endpoints per chain. The wallet automatically tries each RPC in order if one fails — no manual switching required, no silent transaction failures.

Security

Your keys, locked
by cryptography.

Every security feature in Nexus Wallet is verifiable in the open-source build. No marketing claims — only what is actually implemented.

🛡
Encrypted Storage AES-256-GCM
Private keys are never stored in plaintext. Each key is encrypted with AES-256-GCM before being saved. Legacy plaintext keys detected on read are automatically re-encrypted to the v4 format.
🔑
Key Derivation PBKDF2
The encryption key is derived from your PIN or pattern using PBKDF2 with 200,000 SHA-256 iterations. This makes brute-force attacks computationally expensive even on high-end hardware.
🤳
Biometric Authentication
Supports Fingerprint and Face ID via AndroidX Biometric (androidx.biometric v1.1.0). Biometric unlock is layered on top of the PIN/pattern — if biometric fails, the user falls back to PIN or pattern.
🔢
6-Digit PIN & Pattern Lock
Choose between a 6-digit PIN or a visual pattern lock as your primary credential. Multiple methods can be registered and one set as the default unlock method.
⛔
No Cloud Backup — Ever
Your wallet data is never backed up to Google Drive or any cloud service. The app is configured to block Android's automatic backup system entirely, so your private keys cannot be silently copied to the cloud without your knowledge.

About

One wallet.
Every chain.

Nexus Wallet is a native Android application that wraps a full DeFi interface in a secure, hardware-accelerated WebView. Wallet data is encrypted on-device — no servers, no cloud sync, no custody.

🔑
Full Self-Custody
Your private keys are encrypted and stored only on your device. Nexus Wallet never transmits your keys anywhere.

FAQ

Common questions

Answers based on the actual Nexus Wallet build — not marketing copy.

Yes. Nexus Wallet is fully self-custody. Your private keys are encrypted on your device and are never transmitted to any server. There is no Nexus Wallet backend that holds or has access to your funds. You are the sole controller of your wallet.

Keys are encrypted using AES-256-GCM encryption with a key derived from your PIN or pattern via PBKDF2 (200,000 SHA-256 iterations). The plaintext key exists only in memory during active use. Android system backups are explicitly blocked so keys cannot be extracted via cloud backup.

Nexus Wallet supports multiple EVM-compatible networks: Ethereum (1), Polygon (137), Arbitrum (42161), Optimism (10), Base (8453), BNB Smart Chain (56), Avalanche C-Chain (43114), and zkSync Era (324). You can also add any custom EVM network by entering the chain ID, RPC URL, and native token symbol.

Yes. Nexus Wallet supports importing wallets via 12 or 24-word BIP-39 mnemonic seed phrases using the standard Ethereum derivation path (m/44'/60'/0'/0/0), as well as raw private keys in standard hex format (with or without the 0x prefix).

Transfer Hub is a batch transaction feature that allows you to send assets from multiple wallets simultaneously. It includes a self-transfer mode for consolidating funds from many wallets into a single address — useful for managing a portfolio of wallets across EVM networks.

Nexus Wallet requires Android 7.0 (API level 24) or higher. It targets Android 14 (API level 34). The app is built with Java 17, AndroidX WebKit, and the AndroidX Biometric library. It runs on both ARM and x86 Android devices.

The APK is currently distributed as a debug build via GitHub Actions CI/CD. Play Store publication requires a signed release build. The open-source build process is fully transparent — you can review the GitHub Actions workflow and build the APK yourself from the source code.

The multi-DEX swap engine aggregates quotes from Odos, 1inch, KyberSwap, Enso, Bungee, Velora, and others. Most endpoints work with public access. Some DEX APIs (like 1inch) perform better with a personal API key, which can be configured in the app settings.
