The core concept that the Brokoli DEX will be based on is concentrated liquidity that allows it to charge a climate fee seamlessly on most transactions. This means that traders will bound liquidity within a specific price range, and will not be charged any more for the transaction. However, if the price range is not reached during a transaction, the difference counts as climate fee and is transferred to offset carbon footprint in a decentralised manner. As liquidity providers are free to choose smaller, flexibly chosen increments, a position would only require to keep enough reserves for trading in that range, and therefore can act like a constant product pool with larger reserves within that range. Furthermore, liquidity providers may reduce their transaction costs by concentrating their liquidity in a narrow range around the current price, and adding or removing tokens as the price moves to keep their liquidity active. This is enabled by there not being a limit of how many positions traders can open. However, it is expected that the ranges will generally be bigger on Brokoli than on other DEXs with similar concentrated liquidity structure as the fee goes towards transparent carbon offsets.
