FAQ
Can you build both wallet apps and exchange platforms?
Yes, I develop wallet apps, crypto websites, and full cryptocurrency exchange platforms based on your needs.
How secure will my platform be?
Security is a priority. I implement encryption, secure authentication, and best practices to protect user data and funds.
Can you integrate blockchain networks?
Yes, I work with Ethereum, Binance Smart Chain, and other blockchain systems for full web3 development.
Will my platform be scalable?
Absolutely. I build systems that can handle growth from launch to large user bases.
Do you provide custom features?
Yes, everything can be tailored—from UI/UX to advanced trading and wallet functionalities.
Can you build a custodial and a non-custodial wallet?
Yes. Non-custodial wallets keep private keys with the user, while custodial wallets are managed by your platform. Tell me which model fits your business and I'll build to it.
How secure will my wallet be?
Security is built in from the start: encrypted storage, secure authentication (2FA and biometrics on higher packages) and no plain-text private keys. For high-value platforms, I recommend a separate third-party security audit before launch.
