Four.Meme has introduced a new tax token model, allowing the project to levy taxes on secondary market transactions post-token graduation. These taxes can be allocated to specified wallets, distributed as dividends, used for token burning, or to add liquidity, with all rules set on-chain and immutable. Currently, the model supports only Fair Mode, which includes an anti-sniping feature to deter bot front-running by imposing high transaction fees on initial blocks. This update aims to enhance the BNB Chain ecosystem's sustainability and promote long-term growth.
