Dependence on a solitary relayer for multichain execution is risky because a centralized model inevitably creates a single point of failure. In response, the Executor framework by Wormhole introduces an open marketplace structure defined by three primary pillars.

The first pillar is open participation, which grants anyone the ability to serve as a Relay provider. Next is the concept of competitive quoting, where execution relies on signed quotes. This structure ensures that providers must compete with one another regarding price, reliability, and service terms. The third pillar involves stateless onchain contracts. Since the Executor maintains no persistent state, its role is strictly to log execution requests and broadcast events for Relay Providers to address.

Even with this flexibility, security measures remain uncompromised. The Guardian network verifies every message, each of which is protected by VAAs. Ultimately, this design guarantees that execution remains resilient, competitive, and accessible to all.
