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 * ```\n * contract MyToken is ERC20Upgradeable {\n *     function initialize() initializer public {\n *         __ERC20_init(\"MyToken\", \"MTK\");\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.

Chains are\n * identified by their alias, which is the same as the alias in the `[rpc_endpoints]` section of\n * the `foundry.toml` file. For best UX, ensure the alias in the `foundry.toml` file match the\n * alias used in this contract, which can be found as the first argument to the\n * `setChainWithDefaultRpcUrl` call in the `initialize` function.\n *\n * There are two main ways to use this contract:\n *   1. Set a chain with `setChain(string memory chainAlias, ChainData memory chain)` or\n *      `setChain(string memory chainAlias, Chain memory chain)`\n *   2. Get a chain with `getChain(string memory chainAlias)` or `getChain(uint256 chainId)`.\n *\n * The first time either of those are used, chains are initialized with the default set of RPC URLs.\n * This is done in `initialize`, which uses `setChainWithDefaultRpcUrl`. Defaults are recorded in\n * `defaultRpcUrls`.\n *\n * The `setChain` function is straightforward, and it simply saves off the given chain data.\n *\n * The `getChain` methods use `getChainWithUpdatedRpcUrl` to return a chain. For example, let's say\n * we want to retrieve `mainnet`'s RPC URL:\n *   - If you haven't set any mainnet chain info with `setChain`, you haven't specified that\n *     chain in `foundry.toml` and no env var is set, the default data and RPC URL will be returned.\n *   - If you have set a mainnet RPC URL in `foundry.toml` it will return that, if valid (e.g. if\n *     a URL is given or if an environment variable is given and that environment variable exists).\n *     Otherwise, the default data is returned.\n *   - If you specified data with `setChain` it will return that.\n *\n * Summarizing the above, the prioritization hierarchy is `setChain` -> `foundry.toml` -> environment variable -> defaults.\n */\nabstract contract StdChains {\n    VmSafe private constant vm = VmSafe(address(uint160(uint256(keccak256(\"hevm cheat code\")))));\n\n    bool private initialized;\n\n    struct ChainData {\n        string name;\n        uint256 chainId;\n        string rpcUrl;\n    }\n\n    struct Chain {\n        // The chain name.\n        string name;\n        // The chain's Chain ID.\n        uint256 chainId;\n        // The chain's alias.
