ArbiFuel leverages ERC-4337 Paymasters, smart-contract mechanisms that can cover gas fees on behalf of users.\ The current integration is powered by Pimlico’s ERC-20 Paymasters, enabling gasless interactions for eligible operations during the sponsorship period.\ \ For official program information, visit:\
