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.

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. 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.

Use 50% forced max utilization ratio as initial game theory - have a global utilization limit and a user-signalled utilization limit (based on shares signalling) \n\n2. When pool shares are burned, give the lender : [ their pct shares * ( currentPrincipalTokens in contract, totalCollateralShares, totalInterestCollected) ] and later, they can burn the collateral shares for any collateral tokens that are in the contract. \n3. use noahs TToken contract as reference for ratios -> amt of tokens to get when committing \n4. Need price oracle bc we dont want to use maxPrincipalPerCollateral ratio as a static ideally \n5. have an LTV ratio \n\nEvery time a lender deposits tokens, we can mint an equal amt of RepresentationToken\n\n\n// -- LIMITATIONS \n1. neither the principal nor collateral token shall not have more than 18 decimals due to the way expansion is configured\n\n\n// -- EXITING \n\nWhen exiting, a lender is burning X shares \n\n - We calculate the total equity value (Z) of the pool multiplies by their pct of shares (S%) (naive is just total committed princ tokens and interest , could maybe do better )\n - We are going to give the lender (Z * S%) value. The way we are going to give it to them is in a split of principal (P) and collateral tokens (C) which are in the pool right now. Similar to exiting a uni pool . C tokens will only be in the pool if bad defaults happened. \n \n NOTE: We will know the price of C in terms of P due to the ratio of total P used for loans and total C used for loans \n \n NOTE: if there are not enough P and C tokens in the pool to give the lender to equal a value of (Z * S%) then we revert . \n\n// ---------\n\n\n// ISSUES \n\n1. for 'overall pool value' calculations (for shares math) an active loans value should be treated as \"principal+interest\"\n aka the amount that will be paid to the pool optimistically. DONE \n2. Redemption with ' the split' of principal and collateral is not ideal . What would be more ideal is a \"conversion auction' or a 'swap auction'. \n In this paradigm, any party can offer to give X principal tokens for the Y collateral tokens that are in the pool. the auction lasts (1 hour?) and this way it is always only principal tha is being withdrawn - far less risk of MEV attacker taking more C -- DONE \n3. it is annoying that a bad default can cause a pool to have to totally exit and close ..this is a minor issue. maybe some form of Insurance can help resurrect a pool in this case, mayeb anyone can restore the health of the pool w a fn call. \n a. fix this by changing the shares logic so you do get more shares in this event (i dont think its possible) \n b. have a function that lets anyone donate principal tokens to make the pool whole again . (refill underwater pools w insurance fund??)\n c. lets pools expire and get unwound and withdrawn completely , make a new pool \n\n4. build a function to do lender close loan \n\n\n\nTODO: \nA.
