Our goal is to create a fair and transparent financial ecosystem that empowers users to take control of their own assets. One of the key features of Protocol X is our buy and sell tax, which is set at 4% and 8% respectively. 50% of the buy tax is distributed to holders of our native token, $PTX, while the other 50% is burnt. This means that buy transactions are essentially sell-less, which helps to support the value of PTX. Similarly, 50% of the sell tax is used to purchase PUSD, our native appreciating stablecoin. The other 50% is burnt, which helps to maintain the constant volume of PUSD and support its value. By distributing PUSD through our tax system, we ensure that it has a constant demand, which allows its price to grow over time. To claim these rewards, users must single stake their PTX within the PTX Vault on our [dApp](https://app.ptxcrypto.com/). This allows them to earn a share of the buy and sell tax revenues, and benefit from the growth of PUSD. In addition to our tax system, we also offer X-Shares, our non-fungible token (NFT) project. X-Shares provide holders with bi-weekly rewards in PUSD from trading profits. This allows them to earn passive income from their NFT assets, and benefit from the success of our trading strategies. Overall, Protocol X is a unique and innovative DeFi project that offers multiple ways for users to earn rewards and grow their assets. We invite you to join us and participate in our growing community. --- # Agent Instructions This documentation is published with GitBook.
