Implement Unified Bridge Adapter Interface

Overview

This PR introduces a standardized BridgeAdapter interface to simplify integration of multiple blockchain bridges into BridgeWise. By normalizing data across bridges, developers can add new integrations with minimal changes to core logic, while downstream consumers (wallets, dApps, analytics) benefit from consistent data structures.

Objective

• Define a standard BridgeAdapter interface for all bridge integrations
• Normalize bridge data including:
  • Fees
  • Estimated Time of Arrival (ETA)
  • Token mapping across chains
• Enable plug-and-play addition of new bridges
• Simplify downstream consumption by wallets, dApps, and analytics

Benefits

• Reduces complexity and errors when adding new bridges
• Provides consistent data for product teams and analytics dashboards
• Improves developer experience with a unified integration pattern
• Supports scalability for future bridge expansions

Labels

• sdk
• integration
• feature
• blockchain
