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]. * ==== */ abstract contract ERC4626Upgradeable is Initializable, ERC20Upgradeable, IERC4626 { using Math for uint256; /// @custom:storage-location erc7201:openzeppelin.storage.ERC4626 struct ERC4626Storage { IERC20 _asset; uint8 _underlyingDecimals; } // keccak256(abi.encode(uint256(keccak256("openzeppelin.storage.ERC4626")) - 1)) & ~bytes32(uint256(0xff)) bytes32 private constant ERC4626StorageLocation = 0x0773e532dfede91f04b12a73d3d2acd361424f41f76b4fb79f090161e36b4e00; function _getERC4626Storage() private pure returns (ERC4626Storage storage $) { assembly { $.slot := ERC4626StorageLocation } } /** * @dev Attempted to deposit more assets than the max amount for `receiver`. */ error ERC4626ExceededMaxDeposit(address receiver, uint256 assets, uint256 max); /** * @dev Attempted to mint more shares than the max amount for `receiver`. */ error ERC4626ExceededMaxMint(address receiver, uint256 shares, uint256 max); /** * @dev Attempted to withdraw more assets than the max amount for `receiver`. */ error ERC4626ExceededMaxWithdraw(address owner, uint256 assets, uint256 max); /** * @dev Attempted to redeem more shares than the max amount for `receiver`. */ error ERC4626ExceededMaxRedeem(address owner, uint256 shares, uint256 max); /** * @dev Set the underlying asset contract.
