Next-Generation Web3 Wallets Built for Security and Mainstream UX.
We build intuitive non-custodial wallets, browser extensions, and ERC-4337 smart accounts that eliminate seed phrases and gas headaches.
What we build under Web3 Wallet Development
Account Abstraction Wallets (ERC-4337)
Smart contract accounts powered by ERC-4337, featuring biometric passkey authentication, social recovery, and gas sponsorship.
- Passkey & FaceID WebAuthn signers
- Paymaster gas sponsorship (zero gas fees)
- Social guardian account recovery
- Batched multi-call transactions
Non-Custodial Mobile & Desktop Wallets
Bespoke iOS, Android, and Electron wallet applications with hardware-backed Secure Enclave private key protection.
- Multi-chain token balance indexing
- In-app token swaps and bridge routes
- Hardware wallet connection (Ledger / Trezor)
- Push notifications for incoming funds
Browser Extension Wallets
Secure Chromium and Firefox browser extensions that inject Web3 providers (EIP-1193) into decentralized web applications.
- EIP-1193 provider injection
- DApp permission management
- Malicious address & phishing detection
- Custom RPC network addition
Overcoming critical architectural bottlenecks
Users losing their life savings by misplacing 12-word recovery seed phrases.
We implement ERC-4337 smart accounts and MPC (Multi-Party Computation) enabling social recovery and biometric passkeys.
New users needing to purchase native cryptocurrency just to pay transaction fees.
We configure paymasters allowing users to pay gas in stablecoins (USDC) or allowing your app to sponsor gas entirely.
Users approving malicious wallet draining transactions unknowingly.
We incorporate transaction simulation engines that preview asset balance changes before the user confirms the signature.
Architectural Standards & Competencies
ERC-4337 Smart Account Architecture
UserOperation bundlers, entry point contracts, and paymaster integration.
Passkey & Biometric Authentication
Signing cryptographic transactions using Apple FaceID and Android Biometrics via WebAuthn.
Secure Enclave Hardware Storage
Storing private keys inside isolated hardware security modules on mobile devices.
Pre-Transaction Simulation
Simulating on-chain execution to display exactly what assets will leave or enter the wallet.
Modern Toolchains We Deploy
Zero-Vulnerability Wallet Engineering
- Private keys and seeds never touch central servers or persistent unencrypted memory
- Hardware-backed encryption (iOS Keychain / Android KeyStore) for all key material
- Pre-transaction simulation showing clear asset inflow and outflow breakdowns
- Strict Content Security Policies (CSP) on browser extensions preventing script injection
Phased delivery timeline
Key Management Architecture
Choosing between non-custodial seed phrases, MPC key shares, or ERC-4337 smart accounts.
Security Threat Modeling
Auditing memory exposure, clipboard sniffing risks, and secure key derivation paths.
Interface & Biometric Integration
Designing an intuitive, friendly wallet interface with FaceID and passkey authentication.
Bundler & Paymaster Setup
Hooking ERC-4337 bundlers and sponsoring policies for gasless user transactions.
Penetration Testing & Release
Conducting rigorous mobile security audits and publishing to Apple App Store and Chrome Web Store.
Real-world deployment use cases
Gasless Consumer Wallet for Web3 Gaming
A mobile gaming studio needed an embedded wallet where gamers could trade items without paying gas fees.
Deployed an ERC-4337 smart wallet with passkey login and paymaster gas sponsorship, boosting onboarding completion by 74%.
Multi-Chain Corporate Treasury Mobile Wallet
An enterprise needed a secure mobile wallet for executives to approve protocol multisig transactions on the move.
Created a hardened React Native wallet integrating WalletConnect and Ledger Bluetooth signing.
Security & performance considerations
Hardware-Isolated Signatures
Signatures are generated within the device's hardware chip, shielded from malicious software.
Phishing Blacklist Telemetry
Real-time checking against known malicious Web3 domain registries before approving dapps.
