FAQ
Is the wallet non-custodial?
Yes. Private keys and seed phrases are generated and encrypted on the user’s device (Keychain/Keystore) and never sent to any server.
Which blockchains do you support?
Ethereum, BNB Chain, Polygon, Base, Avalanche, Arbitrum, Solana, Tron and Bitcoin. Other chains like XRP, Cardano or SUI can be added after a quick feasibility check.
Can you build a wallet like Trust Wallet or MetaMask?
Yes. Same core features (multichain, swap, dApp browser, WalletConnect), built under your own brand and design.
Do I get the source code?
Yes, full source code is included in all packages.
Will you publish the app on the App Store and Play Store?
Yes. You’ll need your own Apple and Google developer accounts.
Can you work with my design?
Yes, from Figma or screenshots. If you don’t have a design, I can create one in Figma as an extra.
Do you provide support after delivery?
Yes. Bugs found within 30 days of delivery are fixed free. New features are quoted separately.
