The Opportunity

Problem

Solo founders can't acquire non-crypto native users for web3 apps because wallets and gas fees scare them off, making growth nearly impossible without massive marketing budgets.

Solution

GasShield lets founders preload gas credits for user transactions, abstracted via a simple SDK. Users act without wallets or fees; you control budgets per campaign. Perfect for viral growth loops targeting mainstream audiences.
