Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the value {ERC20} uses, unless {_setupDecimals} is called. 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}.

approve(spender: address, amount: uint256)
nonpayable
Approve spender to transfer up to amount of your tokens from your account.✨ AI
开发者： Sets `amount` as the allowance of `spender` over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.

decreaseAllowance(spender: address, subtractedValue: uint256)
nonpayable
Decrease the caller's ERC-20 allowance for spender by subtractedValue.✨ AI
开发者： Atomically decreases the allowance granted to `spender` by the caller. This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}. Emits an {Approval} event indicating the updated allowance. Requirements: - `spender` cannot be the zero address. - `spender` must have allowance for the caller of at least `subtractedValue`.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| spender | address | Address allowed to spend tokens whose allowance will be reduced.✨ AI |

renounceRole(role: bytes32, account: address)
nonpayable
Allows an account to renounce a role it currently holds.✨ AI
开发者： Revokes `role` from the calling account. Roles are often managed via {grantRole} and {revokeRole}: this function's purpose is to provide a mechanism for accounts to lose their privileges if they are compromised (such as when a trusted device is misplaced). If the calling account had been granted `role`, emits a {RoleRevoked} event. Requirements: - the caller must be `account`.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
