  /**
   * @dev 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.
   *
   * ==== Security Considerations
   *
   * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
   * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
   * considered as an intention to spend the allowance in any specific way. The second is that because permits have
   * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
   * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
   * generally recommended is:
   *
   * ```solidity
   * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
   *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
   *     doThing(..., value);
   * }
   *
   * function doThing(..., uint256 value) public {
   *     token.safeTransferFrom(msg.sender, address(this), value);
   *     ...
   * }
   * ```
   *
   * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
   * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
   * {SafeERC20-safeTransferFrom}).
   *
   * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
   * contracts should have entry points that don't rely on permit.

  /**
   * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
   * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
   * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
   * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
   *
   * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
   * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
   * case an upgrade adds a module that needs to be initialized.
   *
   * For example:
   *
   * [.hljs-theme-light.nopadding]
   * ```solidity
   * contract MyToken is ERC20Upgradeable {
   *     function initialize() initializer public {
   *         __ERC20_init("MyToken", "MTK");
   *     }
   * }
   *
   * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
   *     function initializeV2() reinitializer(2) public {
   *         __ERC20Permit_init("MyToken");
   *     }
   * }
   * ```
   *
   * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
   * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
   *
   * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
   * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
   *
   * [CAUTION]
   * ====
   * Avoid leaving a contract uninitialized.
   *
   * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
   * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
   * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
   *
   * [.hljs-theme-light.nopadding]
   * ```
   * /// @custom:oz-upgrades-unsafe-allow constructor
   * constructor() {
   *     _disableInitializers();
   * }
   * ```

   * @dev Extension of {AccessControl} that allows specifying special rules to manage

   *
   * If a specific role doesn't have an admin role assigned, the holder of the

   * This contract implements the following risk mitigations on top of {AccessControl}:

   * * Only one account holds the `DEFAULT_ADMIN_ROLE` since deployment until it's potentially renounced.
   * * Enforces a 2-step process to transfer the `DEFAULT_ADMIN_ROLE` to another account.
   * * Enforces a configurable delay between the two steps, with the ability to cancel before the transfer is accepted.
   * * The delay can be changed by scheduling, see {changeDefaultAdminDelay}.
   * * It is not possible to use another role to manage the `DEFAULT_ADMIN_ROLE`.
