The market for what happens next — a mobile-first prediction market built on Arc, Circle's stablecoin-native L1 where USDC is the gas token.
Puls lets anyone trade on real-world predictions in seconds. You sign in with Google, a gasless Circle MPC smart wallet is created for you instantly — no seed phrase, no ETH — and you swipe to trade markets funded in USDC on Arc Testnet. Markets settle through UMA's optimistic oracle.
Arc is the only chain where USDC is the native gas token. Users never need ETH, fees are predictable, and trades confirm in under a second — unlocking a UX that isn't possible elsewhere.
