The Processor uses a pipeline architecture with Planner, Fetcher, and Arbiter goroutines communicating through channels, supporting both sync mode (batch fetching with adjustable windows) and live mode (per-block indexing with finality). The Decoder handles both static and dynamic ABI types with explicit routing to avoid signature collisions between contracts. The system is designed for reliability with automatic reorg detection, retryable RPC calls, and atomic commit/rollback operations. ## Full article daily.dev links to this article rather than hosting it.
