Development Philosophy

WalletAgent follows a developer-first approach:

Safety-First Development

• Mock Mode Default - Safe testing environment for all experimentation

• Contract Simulation - Test functions without gas costs or state changes

• Transaction Previews - See exactly what will happen before execution

• Comprehensive Validation - Catch errors before they cost gas

AI-Native Development

• Prompts - Code with conversational interfaces

• Context Awareness - AI understands your project structure and goals

• Intelligent Suggestions - Get recommendations based on best practices

• Error Explanations - Clear guidance when things go wrong

Multi-Chain by Default

• Chain Abstraction - Write code once, deploy everywhere

• Network Switching - Seamlessly move between development and production

• Cross-Chain Patterns - Built-in support for multi-chain architectures

• Built-in Network Support - Work with major EVM-compatible blockchains

Development Workflow

1. Setup & Configuration

# Verify your WalletAgent installation
Get wallet info

2. Project Integration

# Load your Wagmi configuration  
Load wagmi config from ./src/generated.ts

# Analyze your contracts
List all available contracts
Analyze MyContract contract capabilities

3. Safe Development

# Test contract functions safely
Test contract function mint for MyNFT
Simulate transfer function for MyToken
Dry run transaction: deploy MyContract

4. Deployment & Verification

# Deploy to testnet
Switch to Sepolia
Deploy MyContract with constructor args [arg1, arg2]
Verify deployment on Sepolia

Key Features for Developers

Contract Simulation Engine

Test any smart contract function without gas costs:

Simulate mint function for MyNFT with recipient 0x123... and tokenId 1

Benefits:

• ✅ Zero Gas Cost - Test complex functions for free

• ✅ State Preservation - Blockchain state remains unchanged

• ✅ Error Detection - Catch reverts before execution

• ✅ Return Value Preview - See function outputs

Automated Test Generation

Generate comprehensive test scenarios automatically:

Test contract function transfer for MyToken

Auto-Generated Tests:

• Basic success scenarios with typical inputs

• Edge cases (zero values, maximum values)

• Boundary conditions (zero addresses, overflow)

• Error conditions with expected revert reasons

Wagmi Integration

Seamlessly integrate with your existing Wagmi setup:

# Extract contract information
Extract ABI for MyToken in TypeScript format
List all view functions for MyContract
Export MyNFT ABI to ./abis/MyNFT.json

# Generate documentation
Analyze MyContract capabilities and detect standards

Multi-Chain Development

Deploy and test across multiple networks:

# Test locally
Switch to Anvil
Deploy and test MyContract

# Test on testnet  
Switch to Sepolia
Deploy MyContract to testnet

# Prepare for mainnet
Switch to Ethereum
Estimate deployment costs

Development Environment

Recommended Setup

Local Development:

# Start Anvil for local testing
anvil --host 0.0.0.0 --port 8545

# Connect WalletAgent
Switch to Anvil
Get test wallets from faucet

Testing Pipeline:

# Run comprehensive tests
Test all contract functions
Generate test coverage report
Verify all scenarios pass

Deployment Pipeline:

# Deploy to testnet
Switch to Sepolia
Deploy with test parameters
Verify contract functionality

# Prepare mainnet deployment  
Estimate mainnet costs
Review security checklist
Plan deployment strategy

Required Tools

• Node.js 18+ or Bun - JavaScript runtime

• Foundry/Anvil - Local blockchain for testing

• Wagmi CLI - Contract ABI generation

• AI Agent - Claude Code or Cursor with MCP support

Pro Tip: WalletAgent integrates with your existing development tools. You don't need to change your workflow - just add AI capabilities.

Common Development Patterns

Contract Development Lifecycle

1. Design & Planning

   # Analyze existing contracts for inspiration
   Analyze UniswapV2Router capabilities
   Extract patterns from successful protocols

2. Implementation

   # Write contracts using your favorite tools
   # Use WalletAgent for testing and validation

3. Testing

   # Generate comprehensive test suites
   Test all contract functions
   Generate edge case scenarios
   Verify security properties

4. Deployment

   # Deploy safely with preview and verification
   Dry run deployment to Sepolia
   Deploy with constructor verification
   Verify contract source code

DApp Integration Patterns

1. Frontend Integration

   # Generate Wagmi hooks
   Extract ABI for MyContract in TypeScript
   Generate React hooks from ABI
   Test contract integration

2. Backend Integration

   # Monitor contract events
   Listen for Transfer events from MyToken
   Process transaction receipts
   Update database with blockchain state

3. Multi-Chain Support

   # Deploy across networks
   Deploy MyContract to Polygon
   Deploy MyContract to Arbitrum
   Configure cross-chain communication

Security & Best Practices

Development Security

• Always Start with Mock Mode - Safe experimentation

• Simulate Before Execute - Prevent costly mistakes

• Test Edge Cases - Use automated test generation

• Verify Deployments - Confirm contract correctness

Production Readiness

• Comprehensive Testing - Cover all code paths

• Gas Optimization - Profile and optimize costs

• Security Audits - Professional code review

• Monitoring Setup - Track contract behavior

Multi-Chain Considerations

• Network-Specific Testing - Test on target networks

• Gas Token Management - Account for different fee tokens

• Bridge Integration - Plan cross-chain strategies

• Upgrade Patterns - Design for future improvements
