Enterprise Multi-Signature Crypto Wallet

Our client wanted to launch a branded, white-label crypto wallet that could serve as the primary gateway for their user base to enter Web3 without the friction that plagues most existing mobile wallet solutions. We built a fully self-custodial Crypto Wallet Mobile App from the ground up over 16 weeks, structured across various modules. The app covers the complete user journey from secure wallet creation with seed phrase backup, multi-chain portfolio management, token swaps, NFT gallery, staking, and a built-in dApp browser with WalletConnect integration. Private keys are encrypted locally using device-level secure enclave storage and are never transmitted to any server. The onboarding flow was designed to take a first-time crypto user from download to first transaction in under three minutes, with biometric authentication, guided seed phrase backup, and plain-language transaction summaries throughout.
