# Paymaster SDK

Paymaster technology allows dApps and third-party entities to sponsor gas fees for transactions performed on their platform. It helps business owners and third-party entities to allocate funds for gas fees in a separate account from which gas fees are deducted for transactions carried out by their clients.

The lack of necessity to own source tokens when performing transactions in the Web3 space helps users save money and time and also encourages them to actively make more transactions in the products with sponsored transaction capabilities.
