defaultAdminDelay()
view
→ 0
Returns the configured delay (timelock) that must elapse before an administrative action executes.✨ AI
开发者： Returns the delay required to schedule the acceptance of a {defaultAdmin} transfer started. This delay will be added to the current timestamp when calling {beginDefaultAdminTransfer} to set the acceptance schedule. NOTE: If a delay change has been scheduled, it will take effect as soon as the schedule passes, making this function returns the new delay. See {changeDefaultAdminDelay}.

defaultAdminDelayIncreaseWait()
view
→ 432,000
Returns the waiting period required before a scheduled increase to the default admin delay takes effect.✨ AI
开发者： Maximum time in seconds for an increase to {defaultAdminDelay} (that is scheduled using {changeDefaultAdminDelay}) to take effect. Default to 5 days. When the {defaultAdminDelay} is scheduled to be increased, it goes into effect after the new delay has passed with the purpose of giving enough time for reverting any accidental change (i.e. using milliseconds instead of seconds) that may lock the contract. However, to avoid excessive schedules, the wait is capped by this function and it can be overrode for a custom {defaultAdminDelay} increase scheduling. IMPORTANT: Make sure to add a reasonable amount of time while overriding this value, otherwise, there's a risk of setting a high new delay that goes into effect almost immediately without the possibility of human intervention in the case of an input error (eg. set milliseconds instead of seconds).
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | uint48 | uint48 wait time (in seconds) required before a scheduled default admin delay increase becomes effective.✨ AI |

写入函数
acceptDefaultAdminTransfer()
nonpayable
开发者： Completes a {defaultAdmin} transfer previously started with {beginDefaultAdminTransfer}. After calling the function: - `DEFAULT_ADMIN_ROLE` should be granted to the caller. - `DEFAULT_ADMIN_ROLE` should be revoked from the previous holder. - {pendingDefaultAdmin} should be reset to zero values. Requirements: - Only can be called by the {pendingDefaultAdmin}'s `newAdmin`. - The {pendingDefaultAdmin}'s `acceptSchedule` should've passed.
approve(spender: address, value: uint256)
nonpayable
Set allowance of spender to spend tokens on behalf of msg.sender
开发者： Approve the passed address to spend the specified amount of tokens on behalf of msg.sender. 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
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| spender | address | The address which will spend the funds |
| value | uint256 | The amount of tokens to be spent |
返回值

参数
| 名称 | 类型 | 描述 |

cancelDefaultAdminTransfer()
nonpayable
开发者： Cancels a {defaultAdmin} transfer previously started with {beginDefaultAdminTransfer}. A {pendingDefaultAdmin} not yet accepted can also be cancelled with this function. Requirements: - Only can be called by the current {defaultAdmin}. May emit a DefaultAdminTransferCanceled event.
cancelPermits(count: uint256)
nonpayable
Cancel one or more pending permits
开发者： This function increments the caller's nonce by the specified count, effectively invalidating all permits signed with nonces from the current nonce up to (current + count - 1). Provides a mechanism to cancel pending EIP-2612 permits before expiry.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| count | uint256 | Number of permits to cancel (must be > 0 and <= MAX_NONCE_INCREMENT) Example: - Current nonce: 5 - Call cancelPermits(3) - New nonce: 8 - Canceled permits: those signed with nonces 5, 6, and 7 |
changeDefaultAdminDelay(newDelay: uint48)
nonpayable
开发者： Initiates a {defaultAdminDelay} update by setting a {pendingDefaultAdminDelay} scheduled for getting into effect after the current timestamp plus a {defaultAdminDelay}. This function guarantees that any call to {beginDefaultAdminTransfer} done between the timestamp this method is called and the {pendingDefaultAdminDelay} effect schedule will use the current {defaultAdminDelay} set before calling. The {pendingDefaultAdminDelay}'s effect schedule is defined in a way that waiting until the schedule and then calling {beginDefaultAdminTransfer} with the new delay will take at least the same as another {defaultAdmin} complete transfer (including acceptance). The schedule is designed for two scenarios: - When the delay is changed for a larger one the schedule is `block.timestamp + newDelay` capped by {defaultAdminDelayIncreaseWait}. - When the delay is changed for a shorter one, the schedule is `block.timestamp + (current delay - new delay)`. A {pendingDefaultAdminDelay} that never got into effect will be canceled in favor of a new scheduled change. Requirements: - Only can be called by the current {defaultAdmin}. Emits a DefaultAdminDelayChangeScheduled event and may emit a DefaultAdminDelayChangeCanceled event.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| newDelay | uint48 |

increaseApproval(spender: address, addedValue: uint256)
nonpayable

receiveWithAuthorization(from: address, to: address, value: uint256, validAfter: uint256, validBefore: uint256, nonce: bytes32, v: uint8, r: bytes32, s: bytes32)
nonpayable
Receive a transfer with a signed authorization from the payer
开发者： This has an additional check to ensure that the payee's address matches the caller of this function to prevent front-running attacks. (See security considerations)
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| from | address | Payer's address (Authorizer) |
| to | address | Payee's address |
| value | uint256 | Amount to be transferred |
| validAfter | uint256 | The time after which this is valid (unix time) |
| validBefore | uint256 | The time before which this is valid (unix time) |
| nonce | bytes32 | Unique nonce |
| v | uint8 | v of the signature |
| r | bytes32 | r of the signature |
| s | bytes32 | s of the signature |
reclaimToken()
nonpayable
Reclaim all tokens at the contract address
开发者： Transfers the tokens this contract holds, to the owner of smart contract. Note: This is not affected by freeze constraints.
renounceRole(role: bytes32, account: address)
nonpayable
开发者： See {AccessControl-renounceRole}. For the `DEFAULT_ADMIN_ROLE`, it only allows renouncing in two steps by first calling {beginDefaultAdminTransfer} to the `address(0)`, so it's required that the {pendingDefaultAdmin} schedule has also passed when calling this function. After its execution, it will not be possible to call `onlyRole(DEFAULT_ADMIN_ROLE)` functions. NOTE: Renouncing `DEFAULT_ADMIN_ROLE` will leave the contract without a {defaultAdmin}, thereby disabling any functionality that is only available for it, and the possibility of reassigning a non-administrated role.
