FAQ
What do you need to start my crypto wallet/exchange/fintech app?
A short brief (goal, region), preferred chains (BTC/ETH/SOL, etc.), required features (P2P, swaps, KYC), branding/screens, API/vendor accounts (KYC, on/off-ramp), and any wireframes. I’ll turn this into a sprint plan and timeline.
Do you build custodial or non custodial crypto wallet apps?
Both. By default I deliver non custodial (keys stay on the user’s device, never on my servers). For custodial wallets, you provide a compliant custody/KMS provider and policies; I integrate securely.
Can you add KYC/AML, on/off-ramp and P2P escrow to my app?
Yes. I integrate vetted vendors (e.g., KYC, fraud checks, card/bank ramps) and build P2P escrow with dispute flows. Availability depends on your country; you supply vendor accounts and compliance approvals.
Will you design the app UI/UX or only code it?
I do both. You get clean app UI, user flows, and a reusable design system—then pixel-perfect screens for iOS/Android/Web. This includes accessibility, performance, and conversion-focused fintech UX.
How do you keep a crypto exchange app secure?
Security by design: 2FA/biometrics, encryption at rest/in transit, role-based admin, rate limiting, logs, and audits. We launch testnet/staging first, then production after checks; I can coordinate third-party reviews.
What do I receive on delivery and who owns the IP?
Full source code in a private repo, docs, environment files, CI/CD, admin panel, and deployment scripts. You own the IP after final payment. I assist with App Store/Play Store submission using your accounts.
What are timelines, support, and updates after launch?
MVPs typically ship in 2–3 weeks depending on scope. Packages include a bug-fix window; I offer optional monthly maintenance (SLA, monitoring, minor features). I don’t provide financial/legal advice or licensing.
