 Wormhole is compatible with many [ecosystems](/build/start-building/supported-networks) and integration is straightforward.
 
+Specialized Relayers are custom-built components designed for specific cross-chain applications within the Wormhole protocol. Unlike standard relayers, they can perform off-chain computations and be tailored to optimize gas fees and enhance user experiences.

+Before diving into implementation, it's crucial to understand the core components of Wormhole and how messages are sent and received across chains. This includes understanding VAAs (Verifiable Action Approvals), which are central to the security and functionality of relayers.

 Relayers in the Wormhole context are processes that deliver [Verified Action Approvals (VAAs)](/learn/infrastructure/vaas/){target=\_blank} to their destination, playing a crucial role in Wormhole's security model. They can't compromise security, only availability, and act as delivery mechanisms for VAAs without the capacity to tamper with the outcome.
 
+### Types of Relayers
+
 There are three primary types of relayers discussed:
 
-- **Client-side relaying** - a cost-efficient, no-backend-infrastructure approach relying on user-facing front ends. It provides a simple solution, although it can complicate the user experience due to the manual steps involved
-- **Specialized relayers** - backend components that handle parts of the cross-chain process, offering a smoother user experience and allowing off-chain calculations to reduce gas costs. These relayers could operate through direct listening to the Guardian Network (Spy relaying) or by providing a REST endpoint to accept VAAs to be relayed (REST relaying)
-- **Standard relayers** - a decentralized relayer network that can deliver arbitrary VAAs, reducing the developer's need to develop, host, or maintain relayers. However, they require all calculations to be done on-chain and might be less gas-efficient

+### Key Differences Between Specialized and Standard Relayers
+
+Specialized Relayers are designed for specific use cases, allowing off-chain computations and custom optimizations, such as batching and conditional delivery. They provide flexibility and potential cost savings in gas fees but require additional setup and maintenance. Standard Relayers, on the other hand, offer simplicity and ease of integration but are less customizable and potentially less efficient in gas usage.
