Summary of "Re{solve} Hackathon Workshop: Launch on Mainnet in 1 hour"

Workshop Overview:

The workshop is part of the Re{solve} Hackathon series (6th workshop).
Goal: Build and launch a gasless crypto wallet on mainnet within one hour.
Speaker: Carlos from Chippy Pay (Chp Pay), focusing on gasless wallet infrastructure.

Key Technological Concepts & Product Features

Chippy Pay (GP Stack) Overview:
- Gasless wallet infrastructure designed to onboard users without exposing blockchain complexity.
- Abstracts wallet creation, gas fees, and transaction sponsorship via a paymaster.
- Supports sending/receiving USDC, checking balances, and interacting with smart contracts.
- Compatible with Next.js for web apps and Expo for React Native apps.
- Non-custodial wallets with private keys encrypted by PIN or passkeys (fingerprint, FaceID).
- Supports integration with existing wallets like Argent and Braavos, enabling transaction sponsorship.
Development Environment Setup:
- Uses Next.js app created via npx create-next-app.
- Node.js version 24 and npm 11 recommended.
- Authentication integrated with Clerk (can also use Firebase, Supabase, etc.).
- Clerk dashboard used to configure social logins (Google, TikTok, GitHub).
- Middleware setup to protect routes requiring authentication.
GP Stack SDK and MCP (Multi-Component Prompt):
- Formerly called GPS SDK, now GP Stack with added functionalities.
- MCP is a new feature allowing code generation and component integration via AI-assisted prompts.
- Cursor.dev used as an AI coding assistant to add components, hooks, constants, and UI elements automatically.
- ChatEN registry (by Vercel) used for UI components compatible with Next.js.
- Prompts guide the AI to build wallet MVP with features: wallet creation, USDC send/receive, balance fetching, encrypted private keys.
Wallet Features Built During Workshop:
- Wallet creation with PIN-encrypted private keys.
- Sending and receiving USDC tokens.
- Fetching wallet balance (using public RPCs like Blast API or Infura).
- Transaction sponsorship to cover gas fees, improving user onboarding.
- Real transaction demo performed on mainnet with confirmation via StarScan and Voyager explorers.
Integration and Extensibility:
- Compatible with other wallets (Argent, Braavos) for transaction sponsorship.
- Can build custom wallets or use passkeys for encryption.
- Hooks and templates available for future integration with BTC and other tokens.
- Recommended tools for smart contract creation: Kyro Coder with MCP support.
- Example smart contracts provided (split contracts for apps like Splitwise).
User Experience and Developer Support:
- Emphasis on hiding blockchain complexity for end-users.
- Encouragement to customize UI (responsive, styled components).
- Telegram and Discord communities for support, mentoring, and collaboration.
- Workshop includes guidance on using prompts effectively for rapid MVP development.
- Seed grants and hackathon sponsor tracks available for projects integrating GP Stack.
