# Technical Components The BSV Association's SPV Wallet comprises several technical components that enhance its functionality: #### Block Headers Service The **Block Headers Service** is a critical component that listens to block announcements from nodes, requests block headers, and validates them to ensure they are part of the longest chain of work. This service enables the SPV Wallet to confirm transactions without needing the entire blockchain. #### Client Libraries The SPV Wallet is designed to be flexible and integrable with existing systems. Client libraries are available in **Golang** and **JavaScript**, which wrap the core functionality and can be used to integrate SPV Wallet capabilities into various applications. #### True Peer-to-Peer Exchange The SPV wallet facilitates direct electronic exchanges, allowing users to transact without the need for a trusted third party. This aligns with Bitcoin's original vision of enabling **seamless peer-to-peer transactions**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
