Why I built it

Prediction markets lose most newcomers at the wallet and gas-fee screens. I wanted to see how far account abstraction could remove that friction.

What it does

• Sign in with Google; a smart account is created automatically
• Gas is sponsored, so users pay only in USDC and never need ETH
• Trade on prediction markets without seed phrases or wallet setup

How it’s built

ERC-4337 smart accounts wrapped around prediction-market contracts, with social sign-in through Web3Auth, a React frontend and an Express API.

The hard part

The gas sponsorship layer. An early paymaster accepted malformed operations that could drain the sponsor’s balance; closing those cases took several rewrites before anything was usable.
