Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\\n *\\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\\n * reused. This mechanism prevents re-execution of each \\\"step\\\" but allows the creation of new initialization steps in\\n * case an upgrade adds a module that needs to be initialized.\\n *\\n * For example:\\n *\\n * [.hljs-theme-light.nopadding]\\n * ```solidity\\n * contract MyToken is ERC20Upgradeable {\\n * function initialize() initializer public {\\n * __ERC20_init(\\\"MyToken\\\", \\\"MTK\\\");\\n * }\\n * }\\n *\\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\\n * function initializeV2() reinitializer(2) public {\\n * __ERC20Permit_init(\\\"MyToken\\\");\\n * }\\n * }\\n * ```\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\\n *\\n * [CAUTION]\\n * ====\\n * Avoid leaving a contract uninitialized.\\n *\\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\\n * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke\\n * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:\\n *\\n * [.hljs-theme-light.nopadding]\\n * ```\\n * /// @custom:oz-upgrades-unsafe-allow constructor\\n * constructor() {\\n * _disableInitializers();\\n * }\\n * ```\\n * ====\\n */\\nabstract contract Initializable {\\n /**\\n * @dev Indicates that the contract has been initialized.\\n * @custom:oz-retyped-from bool\\n */\\n uint8 private _initialized;\\n\\n /**\\n * @dev Indicates that the contract is in the process of being initialized.\\n */\\n bool private _initializing;\\n\\n /**\\n * @dev Triggered when the contract has been initialized or reinitialized.\\n */\\n event Initialized(uint8 version);\\n\\n /**\\n * @dev A modifier that defines a protected initializer function that can be invoked at most once.

}Submits a contract source code to Scrollscan for verification.
Requires a valid Scrollscan API key, it will be rejected otherwise
Only supports HTTP POST due to max transfer size limitations for HTTP GET
Supports up to 10 different library pairs
Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files.
List of supported solc versions, only solc version v0.4.11 and above is supported e.g. v0.4.25+commit.59dbf8f1
Upon successful submission you will receive a GUID (50 characters) as a receipt
You may use this GUID to track the status of your submission
Verified Source Codes will be displayed at the Verified Contracts page.
