Token & Coin Platform Build

I already have a live utility token and now need a full-fledged ecosystem around it. The job covers three pillars that must work seamlessly together:

1. A brand-new blockchain coin that can be purchased with our existing token and with fiat or crypto once listings go live. Smart-contract creation, auditing, and deployment are all part of the scope, and I’m open to your recommendation on the most suitable chain.

2. A mobile app for both iOS and Android. Inside the app users will:
• Register or sign in, build a profile, and secure their own in-app wallet.
• Browse and complete simple social-engagement tasks—following our social media pages, subscribing to channels, and watching YouTube videos.
• Earn token rewards instantly after each verified action.
• Swap tokens for the new coin or purchase the coin directly through integrated payment options.

3. A companion website that mirrors the app’s core flow. It needs:
• User registration and profile management.
• A task tracker that records proof-of-completion and auto-releases rewards.
• A unified wallet module displaying token and coin balances plus a buy/swap interface.

Acceptance criteria
• Smart contract passes an independent audit and is published on a public explorer.
• iOS and Android builds are accepted by App Store and Google Play.
• Website is responsive and handles at least 10k concurrent users in test.
• Wallet balances sync in real time across web and mobile.
• Task completion triggers on-chain reward within seconds.

APIs, admin dashboards, and detailed UI assets can be provided as soon as we agree on the architecture. Let me know your proposed tech stack, timeline, and any prior launches you’ve handled that are similar in scope.
