-## ERC20
-
-_Lightweight ERC20 with Permit extension._
-
-### constructor
-
-```solidity
-constructor(string name_, string symbol_) internal
-```
-
-_Sets the values for {name} and {symbol}._
-
-### name
-
-```solidity
-function name() public view virtual returns (string)
-```
-
-_Returns the name of the token._
-
-### symbol
-
-```solidity
-function symbol() public view virtual returns (string)
-```
-
-_Returns the symbol of the token, usually a shorter version of the
-name._
-
-### decimals
-
-```solidity
-function decimals() public view virtual returns (uint8)
-```
-
-_Returns the number of decimals used to get its user representation.
-For example, if `decimals` equals `2`, a balance of `505` tokens should
-be displayed to a user as `5.05` (`505 / 10 ** 2`).
-
-Tokens usually opt for a value of 18, imitating the relationship between
-Ether and Wei. This is the default value returned by this function, unless
-it's overridden.
-
-NOTE: This information is only used for _display_ purposes: it in
-no way affects any of the arithmetic of the contract, including
-{IERC20-balanceOf} and {IERC20-transfer}._

-```
-
-_See {IERC20-approve}.
-
-NOTE: If `value` is the maximum `uint256`, the allowance is not updated on
-`transferFrom`. This is semantically equivalent to an infinite approval._

-
-IMPORTANT: Beware that changing an allowance with this method brings the risk

-## IERC20Permit
-
-_Interface of the ERC20 Permit extension allowing approvals to be made via signatures, as defined in
-https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].
-
-Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
-presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
-need to send a transaction, and thus is not required to hold Ether at all._
-
-### nonces
-
-```solidity
-function nonces(address owner) external view returns (uint256)
-```
-
-_Returns the current nonce for `owner`. This value must be
-included whenever a signature is generated for {permit}.
-
-Every successful call to {permit} increases `owner`'s nonce by one.
-This prevents a signature from being used multiple times._
-
-### DOMAIN_SEPARATOR
-
-```solidity
-function DOMAIN_SEPARATOR() external view returns (bytes32)
-```
-
-_Returns the domain separator used in the encoding of the signature for {permit}, as defined by {EIP712}._
-
-### permit
-
-```solidity
-function permit(address owner, address spender, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external returns (bool)
-```
-
-_Sets `value` as the allowance of `spender` over `owner`'s tokens,
-given `owner`'s signed approval.
-
-IMPORTANT: The same issues {IERC20-approve} has related to transaction
-ordering also apply here.
-
-Emits an {IERC20-Approval} event.
-
-NOTE: `spender` can be the zero address. Checking this on-chain is a bad
-usage of gas. For more information on the signature format, see the
-https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIPsection]._
-
-### permitTransfer
-
-```solidity
-function permitTransfer(address from, address to, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external returns (bool)
-```
-
-_Allows {IERC20-transferFrom} to be used with the `owner`'s signature.
-Similar to permit but changing the scope to handle the balance instead of
-allowance.
-
-Requires less gas than regular {permit} and {IERC20-transferFrom}.
-
-IMPORTANT: `owner` works as `from` and `spender` as `to` (see {IERC20Permit-permit}).
-
-Emits an {IERC20-Transfer} event.
-
-NOTE: Realize that {PERMIT_TYPEHASH} is different from the one in {permit}.
-This is because the arguments name differ. But won't result in a different
-output as long as it is encoded following the EIP712 and ERC20Permit specs._
