Mock USDF Token Contract Development Todo

This document outlines the complete development plan for creating a Mock USDF token contract with LayerZero cross-chain functionality on Flow blockchain.

Phase 1: Environment Setup (High Priority)

1. Set up Flow blockchain development environment and install Flow CLI

2. Configure Flow emulator and create development accounts

  • Initialize Flow project with flow init
  • Start Flow emulator with flow emulator start
  • Create development accounts for testing
  • Configure accounts in flow.json configuration file
  • Fund accounts with test FLOW tokens

3. Deploy LayerZero endpoint contracts on Flow emulator

  • Research LayerZero V2 contracts for Flow EVM compatibility
  • Configure LayerZero endpoint addresses for Flow testnet
  • Deploy or configure existing LayerZero infrastructure
  • Verify LayerZero endpoint connectivity

4. Create and configure Mock USDF token contract for Flow

  • Adapt existing MockUSDF.sol for Flow EVM compatibility
  • Configure contract constructor parameters for Flow
  • Set up proper decimals (6) and token metadata
  • Ensure OpenZeppelin contracts compatibility with Flow

Phase 2: Core Development (Medium Priority)

5. Implement cross-chain messaging functionality using LayerZero

  • Configure OFT (Omnichain Fungible Token) functionality
  • Set up cross-chain message encoding/decoding
  • Implement cross-chain transfer logic
  • Configure trusted remote contracts on other chains

6. Write comprehensive unit tests for Mock USDF contract

  • Test basic ERC20 functionality (transfer, approve, etc.)
  • Test OFT cross-chain operations
  • Test permit functionality (EIP-2612)
  • Test access control and ownership functions
  • Test edge cases and error conditions

7. Create deployment scripts for Flow emulator and testnet

  • Create Foundry deployment script for Flow emulator
  • Create Foundry deployment script for Flow testnet
  • Configure deployment parameters and addresses
  • Add post-deployment verification steps

8. Test Mock USDF contract on Flow emulator locally

  • Deploy contract to local Flow emulator
  • Test all contract functions locally
  • Verify cross-chain messaging simulation
  • Test integration with other mock contracts

9. Configure Flow testnet connections and endpoints

  • Set up Flow testnet RPC endpoints in foundry.toml
  • Configure testnet accounts and private keys
  • Verify testnet connectivity and block explorer access
  • Set up testnet faucet access for test tokens

10. Deploy Mock USDF contract to Flow testnet

  • Execute deployment script on Flow testnet
  • Verify contract deployment and initialization
  • Test basic functionality on testnet
  • Record contract addresses and transaction hashes

Phase 3: Advanced Features (Low Priority)

11. Implement cross-chain bridge functionality for asset transfers

  • Set up bridge contracts for asset locking/minting
  • Configure multi-chain token representations
  • Implement bridge fee mechanisms
  • Test cross-chain asset transfers

12. Create integration tests for cross-chain operations

  • Set up multi-chain testing environment
  • Test cross-chain message delivery
  • Test cross-chain asset transfers end-to-end
  • Test failure scenarios and recovery mechanisms

13. Set up monitoring and logging for deployed contracts

  • Configure contract event monitoring
  • Set up transaction tracking and alerts
  • Implement health checks for cross-chain operations
  • Create dashboard for contract metrics

14. Create documentation for deployment and usage

  • Write deployment guide for developers
  • Create user guide for token interactions
  • Document cross-chain transfer procedures
  • Create troubleshooting guide

15. Verify contracts on Flow testnet explorer

  • Submit contract source code for verification
  • Verify contract on Flow block explorer
  • Test explorer functionality and contract interaction
  • Update documentation with verified contract links

Technical Requirements

Dependencies

  • Flow CLI (latest version)
  • Foundry (for Solidity compilation and testing)
  • LayerZero V2 contracts
  • OpenZeppelin contracts v5.x
  • Node.js and npm (for additional tooling)

Contract Specifications

  • Token Name: Mock USDF
  • Token Symbol: mUSDF
  • Decimals: 6
  • Standard: ERC20 with OFT (Omnichain Fungible Token) extension
  • Features:
    • Cross-chain transfers via LayerZero
    • EIP-2612 Permit functionality
    • Ownable access control
    • Mintable/Burnable capabilities

Network Configuration

Notes

  • Ensure all contracts are thoroughly tested before mainnet deployment
  • Follow security best practices for cross-chain token contracts
  • Keep LayerZero documentation handy for cross-chain configuration
  • Monitor gas costs and optimize contract efficiency
  • Consider audit requirements for production deployment
