WebSocket Sequencer Connection +**Status:** ⚠️ Failing (expected for Anvil testing) +**Error:** `websocket: bad handshake` +**Impact:** Cannot monitor live pending transactions +**Workaround:** Use manual test swaps via Cast for arbitrage testing + +**Why this happens:** +- Anvil's WebSocket implementation differs from mainnet +- Not required for local testing with manual swaps +- Can be tested on testnet/mainnet later + +### 2. Archive RPC Limitation +**Status:** ⚠️ Public RPC doesn't support archive access +**Error:** `missing trie node` when querying factory contracts +**Solution Implemented:** Hardcoded pools for testing +**Production Solution:** Use archive RPC provider (Alchemy, QuickNode, Infura) + +--- + +## Architectural Improvements Made + +### Type System Fixes +1. **Interface usage** - Changed from `*cache.PoolCache` to `cache.PoolCache` +2. **Context propagation** - Added context parameters throughout +3. **Missing fields** - Added `LiquidityUSD`, `MonitorInterval`, `CleanupInterval` +4. **Token decimals** - Added validation for `Token0Decimals` and `Token1Decimals` + +### Configuration Fixes +1. **Parser factory** - Removed incorrect logger parameter +2. **Validator** - Fixed from `DefaultConfig()` to `DefaultValidationRules()` +3. **Arbitrage config** - Fixed field names (`MaxPathsPerPair`, `MinProfitWei`, etc.) +4. **Executor config** - Added missing `MonitorInterval` and `CleanupInterval` + +### Discovery System +1. **Hardcoded pools** - Added for Anvil fork testing +2. **Token pair generation** -
