How Smart Contract Execution Actually Works (Breaking Down the Stack)

Let's talk about the layered architecture that powers on-chain interactions:

**Foundation Layer: Data & Grounding**
Everything starts here. You've got your on-chain state pulled from nodes and indexers, oracle feeds for external data, plus curated knowledge bases. The system runs constant freshness checks and anomaly detection to catch anything sketchy before it propagates.

**The Execution Layer: Where Things Get Real**
This is where pre-audited scripts get deployed. Before anything hits the chain, there's simulation to stress-test the logic. Then comes route selection—the system evaluates which DEX or bridge gives you the best execution path. And here's the critical part: MEV-safe submission ensures your transaction doesn't get sandwiched or front-run by extractive actors.

The whole stack is designed to be transparent and protective. Not just fast, but resilient.
