## 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.
