# Vault Token ### Token Description: The `VaultToken` is a type of tax token that takes a percentage of taxes and keeps them in the token contract to allow tokens to be proportionally redeemed for Ether. It ensures a minimum token price based on past taxes. Users can redeem their tokens for a proportional amount of the Ether held in the contract. ### Token Interface for Maintenance: * `transferTreasury(address _newTreasury)` - Allows the owner or treasury to change the treasury address. * `changeDex(address _dexAddress)` - Allows the owner or treasury to change the address of the dex where taxes should be sold. * `setTaxes(address _dex, uint256 _buyTax, uint256 _sellTax)` - Allows the owner to set buy and sell taxes on the dex. * `changeVaultPercent(uint256 _newVaultPercent)` - Allows the owner or treasury to change the percentage of taxes that are given to the vault. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
