## 7702 Turbo Relayer with Smart Account

The **7702 Turbo Relayer with Smart Account** is Gelato's native EIP-7702 implementation, providing the fastest and most gas-efficient way to send gasless transactions. It allows EOAs to behave like smart accounts without changing their address. In this section you will see implementations for our relayer as well as relayer with smart account.
