Team Pay
Leveraging Circle's Cross-Chain Transfer Protocol (CCTP) V2
Description
## Project Overview
Team Pay is a comprehensive solution for organizations, DAOs, and businesses to manage bulk USDC payments across multiple blockchain networks. Leveraging Circle's Cross-Chain Transfer Protocol (CCTP) V2, Team Pay streamlines the traditionally complex process of sending payments to multiple recipients on different chains.
## Problem Statement
Organizations managing crypto treasuries and payment operations face significant challenges:
- Managing multiple wallets across different chains
- Tracking transactions across disparate networks
- Ensuring recipients have sufficient gas for subsequent transactions
- High operational costs for individual cross-chain transfers
- Lack of unified payment interfaces for treasury management
## Our Solution
Team Pay provides a unified dashboard for managing all aspects of cross-chain USDC payments:
- Bulk Payment Processing: Send USDC to multiple recipients across different networks in a single flow
- Smart Fee Optimization: Choose between fast transfers (8-20s) or standard transfers (13-19m) based on urgency and cost preferences
- Real-time Status Tracking: Monitor all payments with live updates on burning, attestation, and minting processes
- Recipient Management: Upload recipient lists via CSV or add them manually with comprehensive validation
- Zero ETH Warning System: Proactively identify recipient addresses with insufficient gas for future transactions
- Comprehensive Network Support: Works across 7 major mainnet networks and 10+ testnet environments
## Technical Implementation
Team Pay is built with modern web technologies and blockchain standards:
- Frontend: React 18 with TypeScript, Zustand state management, and Tailwind CSS
- Blockchain Integration: ethers.js v6 for contract interactions with Circle's CCTP V2
- Wallet Connection: MetaMask SDK for secure wallet management
- Cross-Chain Operations: CCTP V2 for secure, trustless USDC transfers between networks
- Deployment: Vercel for seamless hosting and CI/CD
## USDC Integration
Team Pay utilizes USDC as its exclusive stablecoin, leveraging:
- Native USDC contracts on all supported chains
- Circle's CCTP V2 for trustless transfers between networks
- Fee estimation for network costs and CCTP transaction fees
- Real-time USDC balance tracking for connected wallets
## Future LI.FI Integration
Our roadmap includes full integration with LI.FI SDK to extend our capabilities:
- Cross-asset swaps during transfers (e.g., USDC to USDT)
- Expanded network support to 30+ blockchains
- Route optimization for lowest fees and fastest settlement
- Access to DEX aggregation for better rates
## Future MetaMask Card Integration
We plan to enhance Team Pay with MetaMask Card capabilities:
- Direct USDC to card funding for team expense management
- Physical card issuance for organizational members
- Spending controls and limits for different team roles
- Automated reporting and reconciliation for card expenses
## Demonstration
Our demo showcases the complete payment flow:
1. Connecting a MetaMask wallet
2. Adding multiple recipients across different networks
3. Selecting transfer method (fast or standard)
4. Executing the bulk payment
5. Monitoring real-time transaction status
6. Viewing zero ETH warnings for recipients
7. Exporting transaction history
## Impact and Use Cases
Team Pay addresses critical needs for:
- DAOs: Managing contributor payments across multiple chains
- DeFi Protocols: Distributing rewards to users on various networks
- Organizations: Streamlining treasury operations and payment processing
- Development Teams: Paying for services and infrastructure across the ecosystem
## Conclusion
Team Pay represents a significant advancement in cross-chain payment infrastructure, making bulk USDC payments accessible, efficient, and user-friendly. By addressing the core challenges of cross-chain treasury management, we're building essential infrastructure for the multi-chain future.
