# Base ERC20 Structure The core of the SYRUP token is based on the audited and battle-tested [ERC20](https://github.com/maple-labs/erc20) contract. The existing ERC20 contract used for xSYRUP and all existing pools will serve as the foundation for MPL V2. The ERC20 contract provides the following functions: ### Public Functions * `approve()`: Allows one account to set the allowance of another account over their tokens. * `decreaseAllowance()`: Allows one account to decrease the allowance of another account over their tokens. * `increaseAllowance()`: Allows one account to increase the allowance of another account over their tokens. * `permit()`: Approve by signature. * `transfer()`: Moves an amount of tokens from `msg.sender` to a specified account. * `transferFrom()`: Moves a pre-approved amount of tokens from a sender to a specified account. ### Internal Functions * `_mint()`: Creates new tokens for a given account and increases the total supply. * `_burn()`: Removes tokens from an account and decreases the total supply. ### Additional Rules At construction time, the SYRUP should do a one time mint of 10% of the supply directly to the treasury. Additionally 10 Million SYRUP will be minted to the migrator contract to facilitate a 1-1 swap from MPL V1 to SYRUP. --- # 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.
