Cube ($CUBE) is the genesis token of Cube Family, a token launchpad on Robinhood Chain built on Uniswap v4 hooks. Every token created through the platform is an ERC-20 that holds its own reward accounting on-chain. A Uniswap v4 hook charges a fixed fee on each swap in the token's pool and splits it between the token's reward recipients and the protocol treasury. $CUBE is paired with ETH and configured in holder-rewards mode with a 3% swap fee. 80% of that fee is distributed to $CUBE holders in ETH and 20% is directed to the protocol. Rewards are allocated in proportion to each wallet's balance using a magnified-dividends-per-share model and require no staking, snapshots, or lock-up periods. Reward eligibility is updated inside the token contract as balances change, and holders withdraw accrued ETH through a stateless claim router. The token's parameters, including its fee and reward mode, are fixed at deployment, and the initial liquidity position was burned at launch.
