FAQ
Which blockchains do you support?
I support Ethereum, Bitcoin, Solana, Binance Smart Chain, Polygon, and most EVM-compatible chains. If you need a specific chain not listed, message me before ordering and I'll confirm availability.
Will I receive the full source code?
Yes — every package includes clean, well-commented source code. You own it fully with no royalties, subscriptions, or lock-in. I also provide a handover document so your team can maintain it going forward.
Is my users' private key stored on your server?
Never. I build non-custodial wallets — private keys are encrypted and stored only on the user's device using AES encryption. No keys ever touch a server. Your users stay in full control of their assets.
Can you build a white-label version for my brand?
Yes. The Premium package includes full white-label customization — your logo, brand colors, custom app name, and splash screen. I can also handle App Store and Google Play submission as a paid extra.
What happens if I need changes after delivery?
Each package includes revision rounds. After revisions are used, I offer affordable post-delivery support. I don't disappear after handover — if something breaks due to my code, I fix it at no extra charge.
