This contract extends\n * the ERC-20 standard. Any additional extensions included along it would affect the \"shares\" token represented by this\n * contract and not the \"assets\" token which is an independent contract.\n *\n * [CAUTION]\n * ====\n * In empty (or nearly empty) ERC-4626 vaults, deposits are at high risk of being stolen through frontrunning\n * with a \"donation\" to the vault that inflates the price of a share. This is variously known as a donation or inflation\n * attack and is essentially a problem of slippage. Vault deployers can protect against this attack by making an initial\n * deposit of a non-trivial amount of the asset, such that price manipulation becomes infeasible. Withdrawals may\n * similarly be affected by slippage. Users can protect against this attack as well as unexpected slippage in general by\n * verifying the amount received is as expected, using a wrapper that performs these checks such as\n * https://github.com/fei-protocol/ERC4626#erc4626router-and-base[ERC4626Router].\n *\n * Since v4.9, this implementation introduces configurable virtual assets and shares to help developers mitigate that risk.\n * The `_decimalsOffset()` corresponds to an offset in the decimal representation between the underlying asset's decimals\n * and the vault decimals. This offset also determines the rate of virtual shares to virtual assets in the vault, which\n * itself determines the initial exchange rate. While not fully preventing the attack, analysis shows that the default\n * offset (0) makes it non-profitable even if an attacker is able to capture value from multiple user deposits, as a result\n * of the value being captured by the virtual shares (out of the attacker's donation) matching the attacker's expected gains.\n * With a larger offset, the attack becomes orders of magnitude more expensive than it is profitable. More details about the\n * underlying math can be found xref:ROOT:erc4626.adoc#inflation-attack[here].\n *\n * The drawback of this approach is that the virtual shares do capture (a very small) part of the value being accrued\n * to the vault. Also, if the vault experiences losses, the users try to exit the vault, the virtual shares and assets\n * will cause the first user to exit to experience reduced losses in detriment to the last users that will experience\n * bigger losses. Developers willing to revert back to the pre-v4.9 behavior just need to override the\n * `_convertToShares` and `_convertToAssets` functions.\n *\n * To learn more, check out our xref:ROOT:erc4626.adoc[ERC-4626 guide].\n * ====\n *\n * [NOTE]\n * ====\n * When overriding this contract, some elements must be considered:\n *\n * * When overriding the behavior of the deposit or withdraw mechanisms, it is recommended to override the internal\n * functions. Overriding {_deposit} automatically affects both {deposit} and {mint}. Similarly, overriding {_withdraw}\n * automatically affects both {withdraw} and {redeem}. Overall it is not recommended to override the public facing\n * functions since that could lead to inconsistent behaviors between the {deposit} and {mint} or between {withdraw} and\n * {redeem}, which is documented to have lead to loss of funds.\n *\n * * Overrides to the deposit or withdraw mechanism must be reflected in the preview functions as well.\n *\n * * {maxWithdraw} depends on {maxRedeem}. Therefore, overriding {maxRedeem} only is enough. On the other hand,\n * overriding {maxWithdraw} only would have no effect on {maxRedeem}, and could create an inconsistency between the two\n * functions.\n *\n * * If {previewRedeem} is overridden to revert, {maxWithdraw} must be overridden as necessary to ensure it\n * always return successfully.\n * ====\n */\nabstract contract ERC4626Upgradeable is Initializable, ERC20Upgradeable, IERC4626 {\n using Math for uint256;\n\n /// @custom:storage-location erc7201:openzeppelin.storage.ERC4626\n struct ERC4626Storage {\n IERC20 _asset;\n uint8 _underlyingDecimals;\n }\n\n // keccak256(abi.encode(uint256(keccak256(\"openzeppelin.storage.ERC4626\")) - 1)) & ~bytes32(uint256(0xff))\n bytes32 private constant ERC4626StorageLocation = 0x0773e532dfede91f04b12a73d3d2acd361424f41f76b4fb79f090161e36b4e00;\n\n function _getERC4626Storage() private pure returns (ERC4626Storage storage $) {\n assembly {\n $.slot := ERC4626StorageLocation\n }\n }\n\n /**\n * @dev Attempted to deposit more assets than the max amount for `receiver`.\n */\n error ERC4626ExceededMaxDeposit(address receiver, uint256 assets, uint256 max);\n\n /**\n * @dev Attempted to mint more shares than the max amount for `receiver`.\n */\n error ERC4626ExceededMaxMint(address receiver, uint256 shares, uint256 max);\n\n /**\n * @dev Attempted to withdraw more assets than the max amount for `receiver`.\n */\n error ERC4626ExceededMaxWithdraw(address owner, uint256 assets, uint256 max);\n\n /**\n * @dev Attempted to redeem more shares than the max amount for `receiver`.\n */\n error ERC4626ExceededMaxRedeem(address owner, uint256 shares, uint256 max);\n\n /**\n * @dev Set the underlying asset contract.
