# 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.
