This contract implements a reentrancy guard to prevent a contract from calling itself or indirectly calling another function that is marked as nonReentrant. It uses a storage variable to track the status of the guard and ensures that only one call is allowed at a time.

/**
 * @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 Contract module that allows children to implement role-based access

 * applications may benefit from on-chain enumerability, for those cases see

 *
 * Roles are referred to by their `bytes32` identifier. These should be exposed

 * 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

 *
 * ```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.

     * * For any other selector, if the restricted function is set on an upgradeable contract, an upgrade may remove

 * @dev A vesting wallet is an ownable contract that can receive native currency and ERC20 tokens, and release these

 *
 * Any assets transferred to this contract will follow the vesting schedule as if they were locked from the beginning.
 * Consequently, if the vesting has already started, any amount of tokens sent to this contract will (at least partly)
 * be immediately releasable.
 *
 * By setting the duration to 0, one can configure this contract to behave like an asset timelock that hold tokens for
 * a beneficiary until a specified time.
 *
 * NOTE: Since the wallet is {Ownable}, and ownership can be transferred, it is possible to sell unvested tokens.
 * Preventing this in a smart contract is difficult, considering that: 1) a beneficiary address could be a
 * counterfactually deployed contract, 2) there is likely to be a migration path for EOAs to become contracts in the
 * near future.
 *
 * NOTE: When using this contract with any token whose balance is adjusted automatically (i.e. a rebase token), make
 * sure to account the supply/balance adjustment in the vesting schedule to ensure the vested amount is as intended.

/**
 * @dev This module connects a {Governor} instance to an {AccessManager} instance, allowing the governor to make calls
 * that are delay-restricted by the manager using the normal {queue} workflow. An optional base delay is applied to
 * operations that are not delayed externally by the manager. Execution of a proposal will be delayed as much as
 * necessary to meet the required delays of all of its operations.
 *
 * This extension allows the governor to hold and use its own assets and permissions, unlike {GovernorTimelockControl}
 * and {GovernorTimelockCompound}, where the timelock is a separate contract that must be the one to hold assets and
 * permissions. Operations that are delay-restricted by the manager, however, will be executed through the
 * {AccessManager-execute} function.
 *
 * ==== Security Considerations
 *
 * Some operations may be cancelable in the `AccessManager` by the admin or a set of guardians, depending on the
 * restricted function being invoked. Since proposals are atomic, the cancellation by a guardian of a single operation
 * in a proposal will cause all of the proposal to become unable to execute. Consider proposing cancellable operations
 * separately.
 *

 * function to be restricted by it. However, admins may configure the manager to make that claim for functions that a
 * governor would want to call directly (e.g., token transfers) in an attempt to deny it access to those functions. To
 * mitigate this attack vector, the governor is able to ignore the restrictions claimed by the `AccessManager` using
 * {setAccessManagerIgnored}. While permanent denial of service is mitigated, temporary DoS may still be technically
 * possible. All of the governor's own functions (e.g., {setBaseDelaySeconds}) ignore the `AccessManager` by default.

/**
 * @dev A forwarder compatible with ERC2771 contracts. See {ERC2771Context}.
 *
 * This forwarder operates on forward requests that include:
 *
 * * `from`: An address to operate on behalf of. It is required to be equal to the request signer.
 * * `to`: The address that should be called.
 * * `value`: The amount of native token to attach with the requested call.
 * * `gas`: The amount of gas limit that will be forwarded with the requested call.
 * * `nonce`: A unique transaction ordering identifier to avoid replayability and request invalidation.
 * * `deadline`: A timestamp after which the request is not executable anymore.
 * * `data`: Encoded `msg.data` to send with the requested call.
 *
 * Relayers are able to submit batches if they are processing a high volume of requests. With high
 * throughput, relayers may run into limitations of the chain such as limits on the number of
 * transactions in the mempool. In these cases the recommendation is to distribute the load among
 * multiple accounts.
 *
 * NOTE: Batching requests includes an optional refund for unused `msg.value` that is achieved by
 * performing a call with empty calldata. While this is within the bounds of ERC-2771 compliance,
 * if the refund receiver happens to consider the forwarder a trusted forwarder, it MUST properly
 * handle `msg.data.length == 0`. `ERC2771Context` in OpenZeppelin Contracts versions prior to 4.9.3
 * do not handle this properly.
 *
 * ==== Security Considerations
 *
 * If a relayer submits a forward request, it should be willing to pay up to 100% of the gas amount
 * specified in the request. This contract does not implement any kind of retribution for this gas,
 * and it is assumed that there is an out of band incentive for relayers to pay for execution on
 * behalf of signers. Often, the relayer is operated by a project that will consider it a user
 * acquisition cost.
 *
 * By offering to pay for gas, relayers are at risk of having that gas used by an attacker toward
 * some other purpose that is not aligned with the expected out of band incentives. If you operate a
 * relayer, consider whitelisting target contracts and function selectors. When relaying ERC-721 or
 * ERC-1155 transfers specifically, consider rejecting the use of the `data` field, since it can be
 * used to execute arbitrary code.

/**
 * @dev Implementation of the ERC4626 "Tokenized Vault Standard" as defined in
 * https://eips.ethereum.org/EIPS/eip-4626[EIP-4626].
 *
 * This extension allows the minting and burning of "shares" (represented using the ERC20 inheritance) in exchange for
 * underlying "assets" through standardized {deposit}, {mint}, {redeem} and {burn} workflows. This contract extends
 * the ERC20 standard. Any additional extensions included along it would affect the "shares" token represented by this
 * contract and not the "assets" token which is an independent contract.
 *
 * [CAUTION]
 * ====
 * In empty (or nearly empty) ERC-4626 vaults, deposits are at high risk of being stolen through frontrunning
 * with a "donation" to the vault that inflates the price of a share. This is variously known as a donation or inflation
 * attack and is essentially a problem of slippage. Vault deployers can protect against this attack by making an initial
 * deposit of a non-trivial amount of the asset, such that price manipulation becomes infeasible. Withdrawals may
 * similarly be affected by slippage. Users can protect against this attack as well as unexpected slippage in general by
 * verifying the amount received is as expected, using a wrapper that performs these checks such as
 * https://github.com/fei-protocol/ERC4626#erc4626router-and-base[ERC4626Router].
 *
 * Since v4.9, this implementation uses virtual assets and shares to mitigate that risk. The `_decimalsOffset()`
 * corresponds to an offset in the decimal representation between the underlying asset's decimals and the vault
 * decimals. This offset also determines the rate of virtual shares to virtual assets in the vault, which itself
 * determines the initial exchange rate. While not fully preventing the attack, analysis shows that the default offset
 * (0) makes it non-profitable, as a result of the value being captured by the virtual shares (out of the attacker's
 * donation) matching the attacker's expected gains. With a larger offset, the attack becomes orders of magnitude more
 * expensive than it is profitable. More details about the underlying math can be found
 * xref:erc4626.adoc#inflation-attack[here].
 *
 * The drawback of this approach is that the virtual shares do capture (a very small) part of the value being accrued
 * to the vault. Also, if the vault experiences losses, the users try to exit the vault, the virtual shares and assets
 * will cause the first user to exit to experience reduced losses in detriment to the last users that will experience
 * bigger losses. Developers willing to revert back to the pre-v4.9 behavior just need to override the
 * `_convertToShares` and `_convertToAssets` functions.
 *
 * To learn more, check out our xref:ROOT:erc4626.adoc[ERC-4626 guide].

/**
 * @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.

 * IMPORTANT: This extension does not call the {_update} function for tokens minted in batch. Any logic added to this
 * function through overrides will not be triggered when token are minted in batch. You may want to also override
 * {_increaseBalance} or {_mintConsecutive} to account for these mints.
 *

/**
 * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
 *
 * The encoding scheme specified in the EIP requires a domain separator and a hash of the typed structured data, whose
 * encoding is very generic and therefore its implementation in Solidity is not feasible, thus this contract
 * does not implement the encoding itself. Protocols need to implement the type-specific encoding they need in order to
 * produce the hash of their typed data using a combination of `abi.encode` and `keccak256`.
 *
 * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
 * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
 * ({_hashTypedDataV4}).
 *
 * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
 * the chain id to protect against replay attacks on an eventual fork of the chain.
 *
 * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
 * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
 *
 * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
 * separator of the implementation contract. This will cause the {_domainSeparatorV4} function to always rebuild the
 * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.

 * BitMaps pack 256 booleans across each bit of a single 256-bit slot of `uint256` type.
 * Hence booleans corresponding to 256 _sequential_ indices would only consume a single slot,
 * unlike the regular `bool` which would consume an entire slot for a single value.
 *
 * This results in gas savings in two ways:
 *
 * - Setting a zero value to non-zero only once every 256 times
 * - Accessing the same warm slot for every 256 _sequential_ indices
