FAQ
Which blockchains do you support?
EVM chains like Ethereum, BNB Chain, Polygon, Base and Avalanche, plus Bitcoin, Solana and Tron. Need another chain? Message me and I’ll confirm before you order.
Can you build both a mobile app and a web app?
Yes. Standard covers mobile or web, Premium covers both, and you can add a web version to Standard as an extra.
Is the wallet custodial or non-custodial?
Non-custodial by default, so private keys stay encrypted on the user’s device. I can also build custodial wallets with a backend and admin panel.
Do I get the full source code?
Yes. You get the full source code with every package, and you own it.
Do you publish to the App Store and Play Store?
Yes. It’s included in Premium and available as an extra for the other packages. You’ll need your own developer accounts.
What do you need from me to start?
Your chains, your feature list, your logo, and Figma designs if you have them. No designs? I’ll use a clean, proven wallet layout.
How do milestones and updates work?
Bigger projects are split into milestones. You get a working build at each one and a progress update every week.
Do you offer support after launch?
Yes, free bug fixes for 14 days after delivery. Ongoing maintenance is available by custom offer.
