About this gig

Are you looking to build a secure, user-friendly, and feature-rich cryptocurrency wallet app? You're in the right place! I'm a professional blockchain developer with extensive experience in creating custom crypto wallet applications for Android, iOS, and web platforms.


I specialize in developing non-custodial and custodial wallets with core features such as wallet creation, private key encryption, multi-coin and token support (BTC, ETH, BNB, ERC20, BEP20, and more), transaction history, QR code scanner, real-time balance updates, integration with blockchain APIs, and two-factor authentication for enhanced security.


Whether you're launching a DeFi project, NFT marketplace, or a standalone crypto wallet, I will deliver a tailored solution that meets your technical and business needs. Youll receive clean, scalable code, intuitive UI/UX, and full documentation to ensure seamless deployment and future upgrades. I also offer smart contract integration, push notifications, wallet connect, and support for hardware wallets upon request. Client satisfaction, security, and performance are my top priorities.
