Exchange, launchpad and social trading app on Arc (Circle's USDC-native chain). Pools are constant-product pairs against USDC where the trading fee is paid in USDC outside the pool and credited on every swap to liquidity providers (exact share), to the token creator's chosen address, and to Arctide's treasury (fixed 0.25%). Tokens launch on a bonding curve with no creator capital; at the goal the contract builds the pool.
