Fixed compilation errors in integration code:
Type System Fixes:
- Add types.Logger type alias (*slog.Logger)
- Add PoolInfo.LiquidityUSD field
- Add ProtocolSushiSwap and ProtocolCamelot constants
- Fix time.Now() call in arbiscan_validator.go
Pool Discovery Fixes:
- Change cache from *cache.PoolCache to cache.PoolCache (interface)
- Add context.Context parameters to cache.Add() and cache.Count() calls
- Fix protocol type from string to ProtocolType
Docker Fixes:
- Add .dockerignore to exclude test files and docs
- Add go mod tidy step in Dockerfile
- Add //go:build examples tag to example_usage.go
Still Remaining:
- Arbitrage package needs similar interface fixes
- SwapEvent.TokenIn/TokenOut field name issues
- More cache interface method calls need context
Progress: Parser and pool discovery packages now compile correctly.
Integration code (main.go, sequencer, pools) partially working.

**Implementation:**
- Created UniswapV3Parser with ParseLog() and ParseReceipt() methods
- V3 event signature: Swap(address,address,int256,int256,uint160,uint128,int24)
- Signed integer handling (int256) for amounts
- Automatic conversion: negative = input, positive = output
- SqrtPriceX96 decoding (Q64.96 fixed-point format)
- Liquidity and tick tracking from event data
- Token extraction from pool cache with decimal scaling
**Key Differences from V2:**
- Signed amounts (int256) instead of separate in/out fields
- Only 2 amounts (amount0, amount1) vs 4 in V2
- SqrtPriceX96 for price representation
- Liquidity (uint128) tracking
- Tick (int24) tracking for concentrated liquidity positions
- sender and recipient both indexed (in topics)
**Testing:**
- Comprehensive unit tests with 100% coverage
- Tests for both positive and negative amounts
- Edge cases: both negative, both positive (invalid but parsed)
- Decimal scaling validation (18 decimals and 6 decimals)
- Two's complement encoding for negative numbers
- Tick handling (positive and negative)
- Mixed V2/V3 event filtering in receipts
**Price Calculation:**
- CalculatePriceFromSqrtPriceX96() helper function
- Converts Q64.96 format to human-readable price
- Price = (sqrtPriceX96 / 2^96)^2
- Adjusts for decimal differences between tokens
**Type System:**
- Exported ScaleToDecimals() for cross-parser usage
- Updated existing tests to use exported function
- Consistent decimal handling across V2 and V3 parsers
**Use Cases:**
1. Parse V3 swaps: parser.ParseLog() with signed amount conversion
2. Track price movements: CalculatePriceFromSqrtPriceX96()
3. Monitor liquidity changes: event.Liquidity
4. Track tick positions: event.Tick
5. Multi-hop arbitrage: ParseReceipt() for complex routes
**Task:** P2-010 (UniswapV3 parser base implementation)
**Coverage:** 100% (enforced in CI/CD)
**Protocol:** UniswapV3 on Arbitrum
