FAQ
Is my users crypto and wallet data secure on the platform?
Every platform I build uses end to end encryption, non custodial wallet standards, and secure key management practices. Your users stay in full control of their funds and your platform stays protected from vulnerabilities that bad actors exploit daily in the crypto space.
Which wallets and blockchains can you integrate?
I integrate MetaMask, Trust Wallet, and WalletConnect across Ethereum, BNB Chain, Polygon, and other EVM compatible networks. If you have a specific blockchain or wallet in mind, message me first and I will confirm compatibility before you order.
Can the platform scale as my trading volume grows?
Yes. The backend is built on scalable cloud infrastructure with Node.js and PostgreSQL, designed to handle high frequency trading activity and growing user bases without performance drops during peak market sessions.
How long before the app is live on App Store and Google Play?
Most builds are store ready within the agreed delivery window. I handle all build configurations and guide you through the full submission process so nothing delays your launch date.
Can I add more coins or trading pairs after launch?
Absolutely. The platform architecture is modular new tokens, trading pairs, or blockchain networks can be added post launch without rebuilding the core system. Your platform scales as your crypto offering grows.
