# SPV Wallets {% embed url="" %} **Component 3: SPV Wallets** The outer layer consists of **SPV (Simplified Payment Verification) wallets**, which empower true peer-to-peer transactions. These wallets allow users to send and receive digital transactions directly, eliminating the need for intermediaries. Utilizing the simplified payment verification method as outlined in Section 8 of the Bitcoin Whitepaper, SPV wallets facilitate instant peer-to-peer transactions both online and offline. They contribute to the BSV blockchain's security, scalability, and cost-efficiency, requiring minimal resources for application developers.
