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.
Is the crypto wallet app non-custodial?
Yes, by default — private keys are generated and stored on the user's device, not on a server I control. This is standard for secure Web3 wallet apps. If your project specifically needs a custodial model, let me know in your project details and we can scope that separately.
Which blockchains do you support?
Ethereum, BSC, Polygon, and Solana are supported out of the box. Additional chains can be added as an add-on — mention your specific chain requirements before ordering so I can confirm compatibility.
an this wallet connect to existing DeFi protocols or dApps?
Yes — WalletConnect and dApp browser integration are included from the Standard package up, so users can connect your wallet to DeFi protocols and Web3 applications directly.
Will I receive the full source code?
Yes, full Flutter/native source code is included on all packages, so you own the codebase outright and aren't locked into ongoing support with me unless you want it.
