Bridging and Cross-Chain Transactions

Overview

Integral automatically detects and captures bridging transactions across multiple blockchain networks, providing seamless tracking of your cross-chain asset movements. Our system recognizes when you move assets between different blockchains and automatically categorizes these transactions as bridge transfers, eliminating the need for manual classification.

How It Works

When a bridging transaction occurs, Integral will:

1. Automatically Detect Bridge Activity: Recognizes transactions involving known bridge protocols and contracts

2. Link Related Transactions: Connect the Bridge Out transaction on the source chain with the Bridge In transaction on the destination chain

3. Categorizes Transactions: Labels transactions as "Bridge Out" (sending) and "Bridge In" (receiving)

4. Enriches Transaction Data: Adds bridging metadata including source/destination chains, addresses, and amounts
