Playing contracts on CEX often leads to black box manipulation. The reason is that CEX will manipulate the "marked price", which is usually set by each exchange themselves, especially for small currencies that can be freely inserted. At the underlying mechanism, only DEX such as Hyperliquid can solve this problem, marking prices openly and transparently. The WalledV I introduced earlier is now integrated with Hyperliquid, and DEX contracts can also be played on mobile phones, providing a very smooth experience. You don't have to worry about being stuck when withdrawing coins and ensuring fund security when trading contracts in the Web3 wallet. Simply search Wallet V on the app store to download, fill in the Liangzi exclusive invitation code: 12105, and say goodbye to Black Box Pin with me!
