Building a Multi-Chain EVM Swap Parser
Normalizing swaps across Ethereum, Base, Arbitrum and BNB Chain without losing protocol-specific meaning.
Normalizing swaps across Ethereum, Base, Arbitrum and BNB Chain without losing protocol-specific meaning.
Event ingestion
Collect receipts and logs with reorg-aware finality. Store chain ID, block hash and transaction index.
Protocol adapters
Decode router, pool and aggregator events through versioned adapters. Unknown contracts need a generic transfer-delta fallback.
Normalization
Emit stable trader, token in/out, raw amount, decimals, venue and USD-value fields while retaining original logs.
Quality controls
Detect duplicate routes, fee-on-transfer tokens, proxy upgrades and reorg reversals. Reconcile aggregate flows against balances.
