Crypto & Web3 Mobile App Development in India
Android and iOS apps for exchanges, wallets and Web3 tools, built from one codebase with secure login and careful store submission.
This page covers phone apps for crypto and Web3 businesses: a trading or portfolio app, a non-custodial wallet, a rewards or loyalty app that touches tokens, or a companion app for a protocol. The same business may also need a web dashboard, which we treat as a separate project.
On a phone the stakes rise. People check balances in a train, on patchy mobile data, on a three-year-old Android handset. They also tap approve without reading. A good app slows down at the right moments. We design those moments, build in Flutter or React Native from one codebase, and plan the Play Store and App Store submission with the sector's extra scrutiny in mind. Compliance remains with your adviser.
What crypto and Web3 businesses need from a mobile app
Login that protects without annoying
Fingerprint or face login, a PIN fallback and automatic lock after inactivity are the baseline. Sensitive actions such as withdrawals should ask again, and new devices should trigger a check by email or SMS.
Alerts that never become advice
Push notifications for order fills, deposits and security events are useful. Notifications that push people to buy or sell cross a line your adviser may not accept, so we keep alert types explicit and switchable.
Store policies that differ by platform
Google Play and Apple both have rules for financial and crypto apps, and they change. Some regions or licences must be shown at submission. We plan this early so review does not become a surprise delay.
Performance on modest phones
Many Indian users run low-memory Android devices with weak signal. Charts and lists must load in pieces, cache the last known state, and say clearly when data is stale.
What we build for crypto and Web3 mobile apps
Portfolio and activity app
Holdings, order history, deposit and withdrawal status, and statements, drawing on your backend. Every figure shows the time it was fetched.
Wallet experience
For non-custodial apps, key storage sits in the phone's secure hardware with a recovery phrase flow written in plain language. We do not see or hold user keys.
Onboarding with camera KYC hand-off
Document and selfie capture through your licensed provider's SDK, with clear retry screens when a photo is rejected. Status comes back to the app within the session.
Security and support tools
Active device list, remote sign-out, spending limits where your product allows them, and an in-app support chat that opens a ticket in your helpdesk.
What it costs
An MVP usually takes 10 to 12 weeks. Wallet security, KYC SDKs and exchange integrations affect scope, so the final fixed quote follows a discovery call.
Questions we get asked
Will Google Play or the App Store accept a crypto app?
It depends on the app type and your licences, and we cannot guarantee approval. Both stores restrict some financial and crypto features and may ask for proof of registration. We prepare the listing, privacy details and test accounts carefully, and tell you early if a feature is likely to be questioned.
Should the app be custodial or non-custodial?
That is a business and legal decision first. A custodial app holds user funds, which needs licences, insurance and heavy security. A non-custodial wallet keeps keys with the user, which shifts risk to them. We build either, but we ask what your adviser has approved.
Can one codebase serve Android and iPhone safely?
Yes. Flutter and React Native handle login, charts and wallet flows well. For secure key storage and biometrics we call the phone's native features through tested libraries. If a specific feature needs native code, we write that part natively and tell you before it affects cost.
Do you build a trading app with live charts?
We can build the screens and connect them to a market data feed you license. Live order books raise load and cost because the data stream is continuous. We keep the first release simpler, with a stable price view and order history, then extend after real usage.
