Our Capabilities
HD Wallet Architecture
BIP-32/39/44 compliant hierarchical deterministic wallets that derive unlimited addresses from a single 12 or 24-word seed phrase. Supports account-level and address-level derivation paths for all major networks.
Multi-Chain Support
Unified wallet experience across Ethereum, Solana, Bitcoin, Polygon, Arbitrum, Optimism, Avalanche, Cosmos, and more. Automatic chain detection, network switching, and cross-chain asset aggregation.
Hardware Wallet Integration
Native support for Ledger and Trezor hardware wallets via HID and WebUSB. Users can sign transactions with maximum security without exposing private keys to software, even for complex DeFi operations.
WalletConnect Protocol
WalletConnect v2 integration for seamless dApp connections via QR code or deep link. Your wallet becomes interoperable with the entire Web3 ecosystem of thousands of dApps out of the box.
Transaction Signing & Security
Secure transaction parsing with human-readable simulation (show users exactly what a transaction will do before signing), phishing detection, malicious contract warnings, and spending limit approvals.
DeFi & NFT Integration
Built-in DeFi portfolio tracking, token swapping via DEX aggregators (1inch, Paraswap), NFT gallery and transfer, staking interfaces, and yield opportunity discovery directly inside the wallet.
How We Work
Security Architecture
We design the security model first: key derivation scheme, storage encryption strategy (AES-256, Secure Enclave on iOS/Android), biometric authentication, and threat model for seed phrase protection.
Key Management Design
Implementation of BIP standards for HD key derivation, secure key storage using platform secure storage (iOS Keychain, Android Keystore), and optional MPC (Multi-Party Computation) for enhanced security.
Development
Wallet application development — transaction construction and signing for each chain, RPC node integration, token balance fetching, NFT discovery, and UI/UX for a frictionless user experience.
Penetration Testing
Comprehensive security audit including static analysis, dynamic testing, memory inspection for key material exposure, and attempted private key extraction. Third-party pen test before public release.
