Pull Request Summary: Major Refactor - Universal Signer Architecture

Overview

This PR introduces a comprehensive architectural refactor that implements a universal signer system with workflow builders, modular adapters, and unified client interfaces across Cosmos, Ethereum, and Injective networks. The changes represent a fundamental shift from network-specific implementations to a unified, extensible architecture.

Key Changes

🏗️ New Universal Architecture

• Workflow Builder System: Introduced a plugin-based workflow builder architecture (packages/types/src/builders/) that enables modular transaction construction and signing processes
• Network Adapters: Created standardized adapters for different blockchain protocols (Tendermint34, Tendermint37, Comet38, Ethereum) to handle protocol-specific differences
• Unified Client Interfaces: Implemented consistent query and event client interfaces across all supported networks

🔧 Signer System Overhaul

• Configurable Signers: Replaced rigid signer implementations with configurable signer classes that support multiple signature formats and algorithms
• Signature Format Handling: Added comprehensive signature format support (COMPACT, FULL, RAW) with configurable processors
• Cross-Network Compatibility: Unified signer interfaces that work seamlessly across Cosmos, Ethereum, and Injective networks

📦 Package Restructuring

• Auth Package Refactor: Complete rewrite of the auth package with new key management, address derivation, and wallet abstractions
• Type System Enhancement: Expanded type definitions with better error handling, protocol interfaces, and builder patterns
• Utility Improvements: Enhanced utility functions for cryptographic operations, HTTP/WebSocket clients, and case conversion

🌐 Network-Specific Improvements

Cosmos Network

• Query Client Refactor: New CosmosQueryClient with comprehensive RPC endpoint support and adapter-based protocol handling
• Workflow Plugins: Modular plugins for amino/direct signing, fee calculation, message encoding, and transaction assembly
• Enhanced Testing: Comprehensive test suites for RPC endpoints, signers, and starship integration

Ethereum Network

• EIP-1559 Support: Full implementation of EIP-1559 transactions with legacy transaction fallback
• Signer Modernization: New base signer architecture with configurable transaction types and signature formats
• Query Client: Standardized Ethereum query client with comprehensive JSON-RPC support

Injective Network

• Signature Processing: Advanced signature processing with configurable formats and Ethereum compatibility
• Wallet Integration: Enhanced EthSecp256k1HD wallet with proper Injective-specific address derivation
• Testing Improvements: Updated test suites with proper queryClientWrapper patterns

📚 Documentation & Testing

• Comprehensive Guides: New network implementation guide and workflow builder documentation
• API Documentation: Updated documentation for all packages with examples and migration guides
• Test Infrastructure: Enhanced test configurations with separate jest configs for different test types (RPC, Starship, unit tests)

Migration Impact

• Breaking Changes: This is a major version change that requires migration from the old signer/builder patterns to the new workflow-based architecture
• Backward Compatibility: Legacy interfaces are deprecated but maintained where possible
• Migration Guide: Updated migration documentation to help users transition from CosmJS and older InterchainJS versions

Files Changed

• 509 files changed: 31,760 additions, 11,667 deletions
• Major additions: New workflow builders, adapters, query clients, and comprehensive type definitions
• Significant deletions: Removed legacy signer implementations, old query clients, and deprecated utilities
• Reorganization: Moved Starship tests from libs to network-specific directories for better organization

This refactor establishes InterchainJS as a truly universal blockchain interaction library with consistent APIs, extensible architecture, and comprehensive multi-network support.
