The Runtime That Decides What Gets Executed — and What Doesn’t

The Execution Engine in Z4R0 acts as a shared contract layer through which all agent-triggered actions are routed. Rather than letting agents interact directly with DeFi protocols, the engine acts as a gatekeeper, ensuring every transaction request is evaluated before it's allowed to proceed on-chain.

Its core responsibility is to perform pre-execution validation. That includes checking whether a transaction aligns with gas fee limits, slippage tolerance, frequency caps, or fallback conditions, based on both the agent’s logic module and the broader system policies. This structure makes execution predictable, enforceable, and traceable.

Technically, the engine operates as a deterministic control layer. It either greenlights execution, delays it, or blocks it outright — always with on-chain transparency. And because it’s deployed as an upgradeable module, new governance-approved rule sets or filters can be added over time, without disrupting existing agents or requiring system resets.
