MineBean

MineBean brings a playful twist to on-chain incentives on Base.

The protocol runs continuous mining rounds where players deploy $ETH and compete for rewards every 60 seconds. Each round takes place on a 5×5 grid of 25 blocks.

Players place ETH on the blocks they believe will win, and when the timer reaches zero one block is selected on-chain using verifiable randomness. Miners who deployed ETH on that block split the ETH placed on every losing block after protocol fees are applied.

Rounds run continuously, creating a fast-moving environment where positioning and participation determine who captures the payouts. The entire system operates through smart contracts, making the outcomes transparent and verifiable on-chain.

🪂 $ETH Rewards and $BEAN Distribution

Alongside the $ETH payouts, MineBean distributes its native token $BEAN through the mining rounds. Each round mints 1 $BEAN, while 0.3 $BEAN is added to the Beanpot, a growing jackpot with a 1-in-777 chance of triggering each round.

BEAN launched as a fair-launch token with zero pre-mine and no team allocation, and the total supply is capped at 3,000,000 $BEAN in the smart contract.

MineBean also introduces a patience mechanic called roasting. When players claim their earned $BEAN, a 10% roasting fee is applied and redistributed to miners who still hold unclaimed tokens. Players who delay claiming accumulate additional roasted $BEAN over time.

Protocol revenue comes from a 1% admin fee on deployed $ETH and a 10% vault fee from the losing pool. This revenue is used by the treasury to buy $BEAN from the liquidity pool, with 90% burned permanently and 10% distributed to $BEAN stakers as yield.
