Key Concepts

• Chain Presets: Register custom chain parameters (block time, reorg safety).
• Client: High-level RPC client with failover support.
• Persistence: Choose between Memory, Redis, or Postgres for tracking progress.
• Scanner: The core engine that orchestrates fetching logs and managing cursors.
• Handler: Define your own logic to process decoded logs.

Code Overview

• pkg/scanner: Core scanning logic.
• pkg/rpc: RPC client wrapper.
• pkg/decoder: ABI-based event decoding.
• pkg/storage: Progress persistence implementations.
