Why Arc

Puls runs on Arc Testnet — a chain purpose-built for stablecoin-native applications. The key property: USDC is the native gas token. There is no separate volatile gas asset to acquire and manage. For a consumer prediction market, that means one unit of account for everything — your balance, your stake, your fees, and the gas (which Puls sponsors anyway).

Network details

Key contract addresses

Gas sponsorship

Puls uses Circle Programmable Wallets for all users. We sponsor all gas fees on the network via a Circle gas-station policy. When you place a trade or buy a signal, the app signs the transaction, but the transaction fees are paid by our gas tank. You only spend what you stake.
