✨ Feature Request: Enhance toSigner Documentation and testing

[joepegler]

Feature or Improvement Description

Improve the toSigner utility by adding comprehensive documentation and test coverage for all major signer types: 1. Viem LocalAccount 2. Viem WalletClient with LocalAccount 3. Viem WalletClient with window.ethereum 4. Ethers JSONRpcSigner 5. Ethers Wallet

Benefits & Outcomes

• Clear Integration Paths: Provide clear examples for each major signer type
• Improved Reliability: Ensure consistent behavior across different signer implementations
• Better Developer Experience: Make it easier to understand which signers are supported
• Reduced Support Issues: Prevent common integration problems
• Testing Confidence: Ensure all signer types work as expected

Implementation Ideas

1. Documentation Updates

   • Add detailed examples for each signer type
   • Document specific configuration requirements
   • Include TypeScript type information
   • Add troubleshooting guides
   • Document limitations and considerations

2. Test Suite Structure

   • Create dedicated test file: toSigner.test.ts
   • Organize tests by signer type
   • Include setup examples
   • Test error conditions
   • Test type inference

3. Test Cases for Each Signer

   Viem LocalAccount:

   • Creation from private key
   • Basic signing operations
   • Type checking

   Viem WalletClient (LocalAccount):

   • Client creation
   • Account integration
   • Signing operations

   Viem WalletClient (window.ethereum):

   • Provider integration
   • Address resolution
   • Signing behavior

   Ethers JSONRpcSigner:

   • Provider setup
   • Signer conversion
   • Method compatibility

   Ethers Wallet:

   • Creation methods
   • Signing operations
   • Error handling

4. Test Environment

   • Mock providers where needed
   • Test network configuration
   • Browser environment simulation
   • Clean state between tests

5. Documentation Examples

   • Installation requirements
   • Import statements
   • Configuration objects
   • Usage patterns
   • Error handling

Technical Considerations

1. Testing Requirements:

   • Unit tests for each signer type
   • Integration tests for real-world scenarios
   • Type checking tests
   • Error case coverage
   • Browser environment testing

2. Documentation Structure:

   • Quick start guide
   • Detailed API reference
   • Migration guides
   • TypeScript types
   • Common patterns

3. Environment Setup:

   • Test utilities
   • Mock implementations
   • Browser simulation
   • Network configuration
