About
Flows Tracker is a real-time cross-chain token transfer monitoring system built with NestJS that tracks and indexes Wormhole bridge transactions between Ethereum Mainnet and Moonbeam networks. It uses Subsquid's EVM data indexing infrastructure to efficiently process blockchain events.
How it's made
Uses Subsquid Pipes for efficient blockchain data streaming, processes three types of smart contract events (LogMessagePublished, TransferRedeemed, and ERC20 Transfer), implements sophisticated filtering logic to track only cross-chain transfers between supported networks, and maintains a comprehensive database of all bridge activity with composite primary keys ensuring data integrity
