TreasuryVault是一个智能合约，用于管理资金的存入、铸造代币、销毁代币以及债务管理。用户可以通过存入ETH来铸造相应的YETH和PT代币，也可以通过销毁这些代币来提取ETH。此外，合约还支持管理借款和还款功能。
sellFee：出售代币时的手续费比例。buyFee：购买代币时的手续费比例。feeTo：手续费收入接收地址。total：合约内部使用的变量，具体作用未在文档中说明。totalDebt：累计债务金额。totalRepay：累计还款金额。PToken：PT代币的地址。YToken：YETH代币的地址。BaseRate：基础兑换比例，ETH与PT/YETH的兑换基数。Deposit：当用户存入ETH并铸造代币时触发。Withdrawal：当用户销毁代币并提取ETH时触发。Borrow：当管理员执行借款操作时触发。Repayment：当管理员执行还款操作时触发。initialize(address _ptoken, address _ytoken)：初始化合约，设置PT和YETH代币的地址。deposit(uint8 _type)：用户存入ETH并根据_type铸造YETH和PT代币。_type为1时，铸造500YETH和500PT；为2时，铸造1000PT。withdraw(uint wad)：用户销毁YETH和PT代币来提取ETH。borrow(uint256 _amount)：管理员从合约中借用指定金额的资金。repayment()：管理员执行还款操作，增加合约的资金。updateSellFee(uint256 _sellFee)：更新出售代币的手续费比例。updateBuyFee(uint256 _buyFee)：更新购买代币的手续费比例。updateFeeTo(address _feeTo)：更新手续费收入接收地址。updatePT(address _pt)：更新PT代币的地址。updateYT(address _yt)：更新YETH代币的地址。updateBaseRate(uint256 _base)：更新基础兑换比例。totalSupply()：返回合约的总供应量。balance()：返回合约的ETH余额。ManagerUpgradeable和PausableUpgradeable，支持权限管理和升级功能。SafeMath库来防止整数溢出。pragma solidity >=0.6.12;
