Crank is an ERC-20 on Ethereum with a Uniswap v4 hook attached at deploy. Every sell triggers a 5% ETH tax, taken from the ETH the seller would receive. That ETH goes into a sealed reserve held by the hook contract — permanently.
Any holder can call redeem(amount) at any time and receive ETH at the current floor price: floor = reserve × 0.995 / supply. The redeemed Crank is burned. The floor goes up. Every redemption benefits everyone still holding.
No tax on buys. No team allocation. No admin. No upgrade. The reserve is mathematically sufficient to honor every outstanding Crank at the current floor, at all times.
Anyone can also send ETH directly to the hook contract — donations go straight into the reserve and raise the floor for every holder.
