= Access Control
[.readme-notice]
NOTE: This document is better viewed at https://docs.openzeppelin.com/contracts/api/access
This directory provides ways to restrict who can access the functions of a contract or when they can do it.
- {AccessControl} provides a general role based access control mechanism. Multiple hierarchical roles can be created and assigned each to multiple accounts.
- {Ownable} is a simpler mechanism with a single owner "role" that can be assigned to a single account. This simpler mechanism can be useful for quick tests but projects with production concerns are likely to outgrow it.

```
Contract module which provides a basic access control mechanism, where
there is an account (an owner) that can be granted exclusive access to
specific functions.
The initial owner is set to the address provided by the deployer. This can
later be changed with {transferOwnership}.
This module is used through inheritance. It will make available the modifier
`onlyOwner`, which can be applied to your functions to restrict their use to
the owner.

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:

[[AccessControl]]
=== `++AccessControl++` link:https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v5.0.0-rc.1/contracts/access/AccessControl.sol[{github-icon},role=heading-link]
[.hljs-theme-light.nopadding]
```solidity
import "@openzeppelin/contracts/access/AccessControl.sol";
```
Contract module that allows children to implement role-based access
control mechanisms. This is a lightweight version that doesn't allow enumerating role
members except through off-chain means by accessing the contract event logs. Some
applications may benefit from on-chain enumerability, for those cases see
{AccessControlEnumerable}.
Roles are referred to by their `bytes32` identifier. These should be exposed
in the external API and be unique. The best way to achieve this is by
using `public constant` hash digests:
```solidity
bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
```
Roles can be used to represent a set of permissions. To restrict access to a
function call, use {hasRole}:
```solidity
function foo() public {
require(hasRole(MY_ROLE, msg.sender));
...
}
```
Roles can be granted and revoked dynamically via the {grantRole} and
{revokeRole} functions. Each role has an associated admin role, and only
accounts that have a role's admin role can call {grantRole} and {revokeRole}.
By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
that only accounts with this role will be able to grant or revoke other
roles. More complex role relationships can be created by using
{_setRoleAdmin}.
WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
grant and revoke this role. Extra precautions should be taken to secure
accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
to enforce additional security measures for this role.

[[AccessControl-renounceRole-bytes32-address-]]
==== `[.contract-item-name]#++renounceRole++#++(bytes32 role, address callerConfirmation)++` [.item-kind]#public#
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 revoked `role`, emits a {RoleRevoked}
event.
Requirements:
- the caller must be `callerConfirmation`.
May emit a {RoleRevoked} event.

After the `schedule` passes, the `newAdmin` will be able to accept the {defaultAdmin} role
by calling {acceptDefaultAdminTransfer}, completing the role transfer.
A zero value only in `acceptSchedule` indicates no pending admin transfer.
NOTE: A zero address `newAdmin` means that {defaultAdmin} is being renounced.

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

After the `schedule` passes, the `newDelay` will get into effect immediately for every
new {defaultAdmin} transfer started with {beginDefaultAdminTransfer}.
A zero value only in `effectSchedule` indicates no pending delay change.
NOTE: A zero value only for `newDelay` means that the next {defaultAdminDelay}
will be zero after the effect schedule.

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.
[.contract-item]
[[IAccessControlDefaultAdminRules-changeDefaultAdminDelay-uint48-]]
==== `[.contract-item-name]#++changeDefaultAdminDelay++#++(uint48 newDelay)++` [.item-kind]#external#
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.
[.contract-item]
[[IAccessControlDefaultAdminRules-rollbackDefaultAdminDelay--]]
==== `[.contract-item-name]#++rollbackDefaultAdminDelay++#++()++` [.item-kind]#external#
Cancels a scheduled {defaultAdminDelay} change.
Requirements:
- Only can be called by the current {defaultAdmin}.
May emit a DefaultAdminDelayChangeCanceled event.
[.contract-item]
[[IAccessControlDefaultAdminRules-defaultAdminDelayIncreaseWait--]]
==== `[.contract-item-name]#++defaultAdminDelayIncreaseWait++#++() → uint48++` [.item-kind]#external#
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).

the `DEFAULT_ADMIN_ROLE` holder, which is a sensitive role with special permissions
over other roles that may potentially have privileged rights in the system.
If a specific role doesn't have an admin role assigned, the holder of the
`DEFAULT_ADMIN_ROLE` will have the ability to grant it and revoke it.
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`.
Example usage:
```solidity
contract MyToken is AccessControlDefaultAdminRules {
constructor() AccessControlDefaultAdminRules(
3 days,
msg.sender // Explicit initial `DEFAULT_ADMIN_ROLE` holder
) {}
}
```

[[AccessControlDefaultAdminRules-renounceRole-bytes32-address-]]
==== `[.contract-item-name]#++renounceRole++#++(bytes32 role, address account)++` [.item-kind]#public#
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.
[.contract-item]
[[AccessControlDefaultAdminRules-_grantRole-bytes32-address-]]
==== `[.contract-item-name]#++_grantRole++#++(bytes32 role, address account) → bool++` [.item-kind]#internal#
See {AccessControl-_grantRole}.
For `DEFAULT_ADMIN_ROLE`, it only allows granting if there isn't already a {defaultAdmin} or if the
role has been previously renounced.
NOTE: Exposing this function through another mechanism may make the `DEFAULT_ADMIN_ROLE`
assignable again. Make sure to guarantee this is the expected behavior in your implementation.

[.contract-item]
[[AccessControlDefaultAdminRules-pendingDefaultAdmin--]]
==== `[.contract-item-name]#++pendingDefaultAdmin++#++() → address newAdmin, uint48 schedule++` [.item-kind]#public#
Returns a tuple of a `newAdmin` and an accept schedule.
After the `schedule` passes, the `newAdmin` will be able to accept the {defaultAdmin} role
by calling {acceptDefaultAdminTransfer}, completing the role transfer.
A zero value only in `acceptSchedule` indicates no pending admin transfer.
NOTE: A zero address `newAdmin` means that {defaultAdmin} is being renounced.
[.contract-item]
[[AccessControlDefaultAdminRules-defaultAdminDelay--]]
==== `[.contract-item-name]#++defaultAdminDelay++#++() → uint48++` [.item-kind]#public#
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}.
[.contract-item]
[[AccessControlDefaultAdminRules-pendingDefaultAdminDelay--]]
==== `[.contract-item-name]#++pendingDefaultAdminDelay++#++() → uint48 newDelay, uint48 schedule++` [.item-kind]#public#
Returns a tuple of `newDelay` and an effect schedule.
After the `schedule` passes, the `newDelay` will get into effect immediately for every
new {defaultAdmin} transfer started with {beginDefaultAdminTransfer}.
A zero value only in `effectSchedule` indicates no pending delay change.
NOTE: A zero value only for `newDelay` means that the next {defaultAdminDelay}
will be zero after the effect schedule.
[.contract-item]
[[AccessControlDefaultAdminRules-defaultAdminDelayIncreaseWait--]]
==== `[.contract-item-name]#++defaultAdminDelayIncreaseWait++#++() → uint48++` [.item-kind]#public#
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).

- `DEFAULT_ADMIN_ROLE` should be granted to the caller.
- `DEFAULT_ADMIN_ROLE` should be revoked from the previous holder.

[[AccessControlDefaultAdminRules-changeDefaultAdminDelay-uint48-]]
==== `[.contract-item-name]#++changeDefaultAdminDelay++#++(uint48 newDelay)++` [.item-kind]#public#
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.

become the new {defaultAdminDelay}.
The value returned guarantees that if the delay is reduced, it will go into effect
after a wait that honors the previously set delay.

[[AccessManager]]
=== `++AccessManager++` link:https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v5.0.0-rc.1/contracts/access/manager/AccessManager.sol[{github-icon},role=heading-link]
[.hljs-theme-light.nopadding]
```solidity
import "@openzeppelin/contracts/access/manager/AccessManager.sol";
```
AccessManager is a central contract to store the permissions of a system.
The smart contracts under the control of an AccessManager instance will have a set of "restricted" functions, and the
exact details of how access is restricted for each of those functions is configurable by the admins of the instance.
These restrictions are expressed in terms of "roles".
An AccessManager instance will define a set of roles. Accounts can be added into any number of these roles. Each of
them defines a role, and may confer access to some of the restricted functions in the system, as configured by admins
through the use of {setFunctionAllowedRoles}.
Note that a function in a target contract may become permissioned in this way only when: 1) said contract is
{AccessManaged} and is connected to this contract as its manager, and 2) said function is decorated with the
`restricted` modifier.
There is a special role defined by default named "public" which all accounts automatically have.
In addition to the access rules defined by each target's functions being assigned to roles, then entire target can
be "closed". This "closed" mode is set/unset by the admin using {setTargetClosed} and can be used to lock a contract
while permissions are being (re-)configured.
Since all the permissions of the managed system can be modified by the admins of this instance, it is expected that
they will be highly secured (e.g., a multisig or a well-configured DAO).
NOTE: This contract implements a form of the {IAuthority} interface, but {canCall} has additional return data so it
doesn't inherit `IAuthority`. It is however compatible with the `IAuthority` interface since the first 32 bytes of
the return data are a boolean as expected by that interface.
NOTE: Systems that implement other access control mechanisms (for example using {Ownable}) can be paired with an
{AccessManager} by transferring permissions (ownership in the case of {Ownable}) directly to the {AccessManager}.
Users will be able to interact with these contracts through the {execute} function, following the access rules
registered in the {AccessManager}. Keep in mind that in that context, the msg.sender seen by restricted functions
will be {AccessManager} itself.
WARNING: When granting permissions over an {Ownable} or {AccessControl} contract to an {AccessManager}, be very
mindful of the danger associated with functions such as {{Ownable-renounceOwnership}} or
{{AccessControl-renounceRole}}.

[[AccessManager-onlyAuthorized--]]
==== `[.contract-item-name]#++onlyAuthorized++#++()++` [.item-kind]#modifier#
Check that the caller is authorized to perform the operation, following the restrictions encoded in
{_getAdminRestrictions}.
[.contract-item]
[[AccessManager-constructor-address-]]
==== `[.contract-item-name]#++constructor++#++(address initialAdmin)++` [.item-kind]#public#
[.contract-item]
[[AccessManager-canCall-address-address-bytes4-]]
==== `[.contract-item-name]#++canCall++#++(address caller, address target, bytes4 selector) → bool immediate, uint32 delay++` [.item-kind]#public#
Check if an address (`caller`) is authorised to call a given function on a given contract directly (with
no restriction). Additionally, it returns the delay needed to perform the call indirectly through the {schedule}
& {execute} workflow.
This function is usually called by the targeted contract to control immediate execution of restricted functions.
Therefore we only return true is the call can be performed without any delay. If the call is subject to a delay,
then the function should return false, and the caller should schedule the operation for future execution.
We may be able to hash the operation, and check if the call was scheduled, but we would not be able to cleanup
the schedule, leaving the possibility of multiple executions. Maybe this function should not be view?
NOTE: The IAuthority interface does not include the `uint32` delay. This is an extension of that interface that
is backward compatible. Some contracts may thus ignore the second return argument. In that case they will fail
to identify the indirect workflow, and will consider calls that require a delay to be forbidden.

[.contract-item]
[[AccessManager-getAccess-uint64-address-]]
==== `[.contract-item-name]#++getAccess++#++(uint64 roleId, address account) → uint48 since, uint32 currentDelay, uint32 pendingDelay, uint48 effect++` [.item-kind]#public#
Get the access details for a given account for a given role. These details include the timepoint at which
membership becomes active, and the delay applied to all operation by this user that requires this permission
level.
Returns:
[0] Timestamp at which the account membership becomes valid. 0 means role is not granted.
[1] Current execution delay for the account.
[2] Pending execution delay for the account.
[3] Timestamp at which the pending execution delay will become active. 0 means no delay update is scheduled.

[[AccessManager-grantRole-uint64-address-uint32-]]
==== `[.contract-item-name]#++grantRole++#++(uint64 roleId, address account, uint32 executionDelay)++` [.item-kind]#public#
Add `account` to `roleId`, or change its execution delay.
This gives the account the authorization to call any function that is restricted to this role. An optional
execution delay (in seconds) can be set. If that delay is non 0, the user is required to schedule any operation
that is restricted to members this role. The user will only be able to execute the operation after the delay has
passed, before it has expired. During this period, admin and guardians can cancel the operation (see {cancel}).
If the account has already been granted this role, the execution delay will be updated. This update is not
immediate and follows the delay rules. For example, If a user currently has a delay of 3 hours, and this is
called to reduce that delay to 1 hour, the new delay will take some time to take effect, enforcing that any
operation executed in the 3 hours that follows this update was indeed scheduled before this update.

==== `[.contract-item-name]#++schedule++#++(address target, bytes data, uint48 when) → bytes32 operationId, uint32 nonce++` [.item-kind]#public#
Schedule a delayed operation for future execution, and return the operation identifier. It is possible to
choose the timestamp at which the operation becomes executable as long as it satisfies the execution delays
required for the caller. The special value zero will automatically set the earliest possible time.
Returns the `operationId` that was scheduled. Since this value is a hash of the parameters, it can reoccur when
the same parameters are used; if this is relevant, the returned `nonce` can be used to uniquely identify this
scheduled operation from other occurrences of the same `operationId` in invocations of {execute} and {cancel}.
Emits a {OperationScheduled} event.
NOTE: It is not possible to concurrently schedule more than one operation with the same `target` and `data`. If
this is necessary, a random byte can be appended to `data` to act as a salt that will be ignored by the target
contract if it is using standard Solidity ABI encoding.

This contract module makes available a {restricted} modifier. Functions decorated with this modifier will be
permissioned according to an "authority": a contract like {AccessManager} that follows the {IAuthority} interface,
implementing a policy that allows certain callers to access certain functions.
IMPORTANT: The `restricted` modifier should never be used on `internal` functions, judiciously used in `public`
functions, and ideally only used in `external` functions. See {restricted}.

[[AccessManaged-restricted--]]
==== `[.contract-item-name]#++restricted++#++()++` [.item-kind]#modifier#
Restricts access to a function as defined by the connected Authority for this contract and the
caller and selector of the function that entered the contract.
[IMPORTANT]
====
In general, this modifier should only be used on `external` functions. It is okay to use it on `public`
functions that are used as external entry points and are not called internally. Unless you know what you're
doing, it should never be used on `internal` functions. Failure to follow these rules can have critical security
implications! This is because the permissions are determined by the function that entered the contract, i.e. the
function at the bottom of the call stack, and not the function where the modifier is visible in the source code.
====
[WARNING]
====
Avoid adding this modifier to the https://docs.soliditylang.org/en/v0.8.20/contracts.html#receive-ether-function[`receive()`]
function or the https://docs.soliditylang.org/en/v0.8.20/contracts.html#fallback-function[`fallback()`]. These
functions are the only execution paths where a function selector cannot be unambiguosly determined from the calldata
since the selector defaults to `0x00000000` in the `receive()` function and similarly in the `fallback()` function
if no calldata is provided. (See {_checkCanCall}).
The `receive()` function will always panic whereas the `fallback()` may panic depending on the calldata length.
