Krypto Kajun 850223a953 fix(multicall): resolve critical multicall parsing corruption issues

- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing
- Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives
- Added LRU caching system for address validation with 10-minute TTL
- Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures
- Fixed duplicate function declarations and import conflicts across multiple files
- Added error recovery mechanisms with multiple fallback strategies
- Updated tests to handle new validation behavior for suspicious addresses
- Fixed parser test expectations for improved validation system
- Applied gofmt formatting fixes to ensure code style compliance
- Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot
- Resolved critical security vulnerabilities in heuristic address extraction
- Progress: Updated TODO audit from 10% to 35% complete

Exchange Components Architecture

Each exchange implements the following component interfaces:

PoolDetector

Discovers pools for token pairs
Handles multiple fee tiers
Identifies pool types

LiquidityFetcher

Fetches pool reserves and data
Calculates spot prices
Estimates liquidity depth

SwapRouter

Calculates swap amounts
Generates transaction data
Validates swaps

Initialization

All exchange implementations are registered and initialized in:

pkg/exchanges/exchanges.go - ExchangeRegistry with InitializeExchangeComponents()

Math Support

The system includes exchange-specific pricing via:

pkg/math/exchange_pricing.go - ExchangePricingEngine with exchange-specific pricers

Arbitrage

Cross-exchange arbitrage opportunities are handled by:

pkg/exchanges/arbitrage_finder.go - CrossExchangeArbitrageFinder

Testing

Each implementation follows the testing strategy defined in:

docs/master-plan/10-development-testing.md

Deployment

Exchange configurations support multiple environments:

pkg/exchanges/deployment_config.go - Multi-environment configurations

Project Status

As of this summary, the MEV Bot supports 7+ major DEX protocols with complete implementations of interfaces, pricing models, and arbitrage capabilities. The system is designed to be extensible for additional exchanges.
