FAQ
Q: Do you write custom smart contracts for the app?
Yes! For the Standard and Premium tiers, I can write, test, and deploy secure Solidity or Rust smart contracts to support custom token logistics, staking, or tailored transaction handling.
How is the security of the seed phrases handled?
Security is paramount. Private keys and seed phrases are heavily encrypted and managed locally on the user's device using secure hardware storage (Keychain/Keystore), ensuring no sensitive keys ever hit a central database.
Can you implement token swap features directly in the app?
Absolutely. I integrate major decentralized exchange aggregation protocols like 1inch, Uniswap, or Jupiter APIs directly into the premium tier so users can seamlessly swap assets without leaving your application.
Will you submit my mobile app to the Apple App Store and Google Play Store?
Yes, I provide comprehensive deployment assistance. Please note that you will need to provide your own Apple Developer and Google Play Console developer accounts.
