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.

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.

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.

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 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.

acts as its own Loan Commitment (for the SmartCommitmentForwarder) and acts as its own Lender in the Teller Protocol.\n\n Lender Users can deposit principal tokens in this contract and this will give them Share Tokens (LP tokens) representing their ownership in the liquidity pool of this contract.\n\n Borrower Users can borrow principal token funds from this contract (via the SCF contract) by providing collateral tokens in the proper amount as specified by the rules of this smart contract.\n These collateral tokens are then owned by this smart contract and are returned to the borrower via the Teller Protocol rules to the borrower if and only if the borrower repays principal and interest of the loan they took.\n\n If the borrower defaults on a loan, for 24 hours a liquidation auction is automatically conducted by this smart contract in order to incentivize a liquidator to take the collateral tokens in exchange for principal tokens.\n\n\n*/\n\ncontract LenderCommitmentGroup_Smart is\n

This pattern implies two\n * things that go hand in hand:\n *\n * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if\n * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.\n * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to\n * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating\n * the proxy admin cannot fallback to the target implementation.\n *\n * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a\n * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to\n * call a function from the proxy implementation.

Consequently, the compiler will not produce an ABI for this contract.

The {ProxyAdmin} of this contract won't send a\n * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.\n *\n * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an\n * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be\n * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an\n * undesirable state where the admin slot is different from the actual admin. Relying on the value of the admin slot\n * is generally fine if the implementation is trusted.\n *\n * WARNING: It is not recommended to extend this contract to add additional external functions.

acts as its own Loan Commitment (for the SmartCommitmentForwarder) and acts as its own Lender in the Teller Protocol.\n\n Lender Users can deposit principal tokens in this contract and this will give them Share Tokens (LP tokens) representing their ownership in the liquidity pool of this contract.\n\n Borrower Users can borrow principal token funds from this contract (via the SCF contract) by providing collateral tokens in the proper amount as specified by the rules of this smart contract.\n These collateral tokens are then owned by this smart contract and are returned to the borrower via the Teller Protocol rules to the borrower if and only if the borrower repays principal and interest of the loan they took.\n\n If the borrower defaults on a loan, for 24 hours a liquidation auction is automatically conducted by this smart contract in order to incentivize a liquidator to take the collateral tokens in exchange for principal tokens.\n\n\n*/\n\ncontract LenderCommitmentGroup_Smart is\n

This pattern implies two\n * things that go hand in hand:\n *\n * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if\n * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.\n * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to\n * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating\n * the proxy admin cannot fallback to the target implementation.\n *\n * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a\n * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to\n * call a function from the proxy implementation.

Consequently, the compiler will not produce an ABI for this contract.

The {ProxyAdmin} of this contract won't send a\n * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.\n *\n * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an\n * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be\n * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an\n * undesirable state where the admin slot is different from the actual admin. Relying on the value of the admin slot\n * is generally fine if the implementation is trusted.\n *\n * WARNING: It is not recommended to extend this contract to add additional external functions.

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.

acts as its own Loan Commitment (for the SmartCommitmentForwarder) and acts as its own Lender in the Teller Protocol.\n\n Lender Users can deposit principal tokens in this contract and this will give them Share Tokens (LP tokens) representing their ownership in the liquidity pool of this contract.\n\n Borrower Users can borrow principal token funds from this contract (via the SCF contract) by providing collateral tokens in the proper amount as specified by the rules of this smart contract.\n These collateral tokens are then owned by this smart contract and are returned to the borrower via the Teller Protocol rules to the borrower if and only if the borrower repays principal and interest of the loan they took.\n\n If the borrower defaults on a loan, for 24 hours a liquidation auction is automatically conducted by this smart contract in order to incentivize a liquidator to take the collateral tokens in exchange for principal tokens.\n\n\n*/\n\ncontract LenderCommitmentGroup_Smart is\n

This pattern implies two\n * things that go hand in hand:\n *\n * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if\n * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.\n * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to\n * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating\n * the proxy admin cannot fallback to the target implementation.\n *\n * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a\n * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to\n * call a function from the proxy implementation.

Consequently, the compiler will not produce an ABI for this contract.

The {ProxyAdmin} of this contract won't send a\n * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.\n *\n * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an\n * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be\n * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an\n * undesirable state where the admin slot is different from the actual admin. Relying on the value of the admin slot\n * is generally fine if the implementation is trusted.\n *\n * WARNING: It is not recommended to extend this contract to add additional external functions.

acts as its own Loan Commitment (for the SmartCommitmentForwarder) and acts as its own Lender in the Teller Protocol.\n\n Lender Users can deposit principal tokens in this contract and this will give them Share Tokens (LP tokens) representing their ownership in the liquidity pool of this contract.\n\n Borrower Users can borrow principal token funds from this contract (via the SCF contract) by providing collateral tokens in the proper amount as specified by the rules of this smart contract.\n These collateral tokens are then owned by this smart contract and are returned to the borrower via the Teller Protocol rules to the borrower if and only if the borrower repays principal and interest of the loan they took.\n\n If the borrower defaults on a loan, for 24 hours a liquidation auction is automatically conducted by this smart contract in order to incentivize a liquidator to take the collateral tokens in exchange for principal tokens.\n\n\n*/\n\ncontract LenderCommitmentGroup_Smart is\n

This pattern implies two\n * things that go hand in hand:\n *\n * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if\n * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.\n * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to\n * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating\n * the proxy admin cannot fallback to the target implementation.\n *\n * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a\n * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to\n * call a function from the proxy implementation.

Consequently, the compiler will not produce an ABI for this contract.

The {ProxyAdmin} of this contract won't send a\n * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.\n *\n * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an\n * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be\n * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an\n * undesirable state where the admin slot is different from the actual admin. Relying on the value of the admin slot\n * is generally fine if the implementation is trusted.\n *\n * WARNING: It is not recommended to extend this contract to add additional external functions.
