 ## Background
 
 Wormhole integrators rely on [various relayers](https://wormhole.com/docs/learn/infrastructure/relayer/) to complete cross-chain actions on behalf of users. The existing systems have some drawbacks however. [Wormhole Relayers](https://wormhole.com/docs/build/contract-integrations/wormhole-relayers/) introduce a significant cost overhead to achieve their goals while custom relayers introduce significant bespoke work for integrators aiming to avoid that overhead.
