Oddity

EthereumRegistered

Oddity is an ERC-20 token ($ODD) and Uniswap v4 hook that imposes a dynamic LP fee per swap: buys are free during a 24-hour prime window if the oracle-submitted Genesis Number is prime, otherwise all trades pay 1%. A Merkle-based prediction reward distributes 3% of supply to winners who guessed the number's last digit.
