-# Overview
-A transaction on Sui takes a payment to execute. The payment, also known as gas, is a list of `0x2::coin::Coin<0x2::sui::Sui>` objects, and paid to Sui validators to secure the network. Although gas is a critical piece in Sui tokenomics, it sometimes adds challenges when new users start to navigate on Sui, especially for web 2.0 users.

-Sponsored transactions can reduce the onboarding friction for users because the feature streamlines the process for end users. Using sponsored transactions, you can execute a transaction without requiring the user to pay it themselves. Instead, you can act as a sponsor of the transaction, offering your own payment gas objects for the transaction.
