# Relayers

A relayer allows users to initiate blockchain transactions without holding the native token required for gas fees. It verifies the user's signature for security, then submits the transaction on their behalf, abstracting away gas payments to enable a smoother user experience.

The Zircuit Relayer service is available on Garfield Testnet and allows to batch multiple calls in a single user operation on the Zircuit Block Explorer. Users have to manually delegate to a EIP7702 Contract Template and are then automatically tapped into the feature on the explorer frontend.
