Pool (ERC 20)

Functions#

_mint#

  function _mint(
  ) internal

_burn#

  function _burn(
  ) internal

approve#

  function approve(
  ) external returns (bool)

transfer#

  function transfer(
  ) external returns (bool)

transferFrom#

  function transferFrom(
  ) external returns (bool)

permit#

  function permit(
  ) external

name#

  function name(
  ) public returns (string)

Returns the name of the token.

symbol#

  function symbol(
  ) public returns (string)

Returns the symbol of the token, usually a shorter version of the name.

decimals#

  function decimals(
  ) public 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 value {ERC20} uses, unless this function is 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}.

totalSupply#

  function totalSupply(
  ) public returns (uint256)

See {IERC20-totalSupply}.

balanceOf#

  function balanceOf(
  ) public returns (uint256)

See {IERC20-balanceOf}.

allowance#

  function allowance(
  ) public returns (uint256)

See {IERC20-allowance}.

DOMAIN_SEPARATOR#

  function DOMAIN_SEPARATOR(
  ) external returns (bytes32)

PERMIT_TYPEHASH#

  function PERMIT_TYPEHASH(
  ) external returns (bytes32)

nonces#

  function nonces(
  ) external returns (uint256)
