/// @title Controller
/// @notice The Controller handles mint and redemption orders for the Tenbin protocol
///
/// Tenbin is an asset token issuance platform with the goal of creating liquid, composable financial assets.
/// Assets in the Tenbin protocol are backed by two positions: off-chain futures contracts and on-chain collateral.
/// An off-chain hedging system maintains a delta one exposure of an underlying asset. On-chain collateral is used to earn low-risk yield.
/// So long as the on-chain yield equals or exceeds the off-chain funding costs, the protocol is able to peg Tenbin assets to the spot price of the real asset.
///
/// The controller contract is responsible for minting and redeeming assets in the Tenbin protocol
/// Mint and redemptions are encoded as an Order. Orders are signed by KYC-approved signers and specify order details such as
/// collateral amount, asset amount, and deadline. To successfully execute an order, a minter account calls the mint or redeem
/// with an order and signature. Orders are executed atomically: collateral is transferred and tokens are minted/burned in a single transaction.
/// All orders are executed by a minter key stored in a hardware security module and controlled by the Tenbin backend.
///
/// When a mint is executed, the collateral is split between a custodian account and a manager account.
/// The controller ratio represents the percentage of collateral to transfer to the the custodian account.
///
/// The controller has several administrative functions to manage order signers, add order beneficiaries, and allow delegating to a signer.
/// Signers are whitelisted by the SIGNER_MANAGER_ROLE.
/// Once a signer is whitelisted, orders signed by this signer are valid so long as the signer == order.payer, or the payer has delegated to a signer.
/// A signer can maintain a list of approved recipients. Only approved recipients for a signer can receive tokens during an order execution.
///
/// The controller never holds any tokens - collateral is held in a CollateralManager contract or off-ramped by a custodian account.
/// An oracle is used as a backstop to prevent order price from deviating from the oracle price.
/// However, order price is not determined by the oracle on-chain.
///
/// The controller is intended to be the only account which can mint asset tokens. In the case a new controller is created,
/// the old controller is deprecated and minting permission is set to the new controller.

 * @dev Contract module that allows children to implement role-based access
 * control mechanisms. This is a lightweight version that doesn't allow enumerating role
 * members except through off-chain means by accessing the contract event logs. Some
 * applications may benefit from on-chain enumerability, for those cases see
 * {AccessControlEnumerable}.
 *
 * Roles are referred to by their `bytes32` identifier. These should be exposed
 * in the external API and be unique. The best way to achieve this is by
 * using `public constant` hash digests:
 *
 * ```solidity
 * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
 * ```
 *
 * Roles can be used to represent a set of permissions. To restrict access to a
 * function call, use {hasRole}:
 *
 * ```solidity
 * function foo() public {
 *     require(hasRole(MY_ROLE, msg.sender));
 *     ...
 * }
 * ```
 *
 * Roles can be granted and revoked dynamically via the {grantRole} and
 * {revokeRole} functions. Each role has an associated admin role, and only
 * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
 *
 * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
 * that only accounts with this role will be able to grant or revoke other
 * roles. More complex role relationships can be created by using
 * {_setRoleAdmin}.
 *
 * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
 * grant and revoke this role. Extra precautions should be taken to secure
 * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
 * to enforce additional security measures for this role.

        "This TOKEN-NOTE (this \"**Token-Note**\" or \"**Note**\") is an integrated instrument that exists as a controllable electronic record as defined in UCC Sec. 12-102(a)(1) (a \"**CER**\") within a form of digital token (the \"**Token**\") dispatched on the Ethereum blockchain (the \"**Token Platform**\").\n\n"
        "On or before the date this Token-Note is issued on the Token Platform (such date, \"**Issue Date**\"), for value received, Tenbin AssetCo (BVI) SPC Ltd., a British Islands segregated portfolio company (the \"**Issuer**\") promises to pay to the order of holder ****by control (within the meaning of UCC Sec. 12-105 (\"**Token Control**\" and, such holder, the \"**Initial Holder**\" and each subsequent holder by Token Control of the Token, from time to time, each a \"**Holder**\"), in the manner and at the place provided below, the principal sum of the U.S. dollar value of one troy ounce of gold priced at the Spot Price (hereinafter defined). Concurrently on the Issue Date, Issuer shall issue the Token on the Token Platform in the aggregate notional amount of one hundred percent (100%) of the Note. Transfers of the Token and ownership by Token Control may thereafter occur solely in accordance with Section 7.\n\n"
        "1. **Spot Price, Valuation**. For purposes of this Note, the Spot Price shall be the PM spot price of gold per troy ounce as published by the London Bullion Market Association (\"**LBMA**\") on the business day that this Note is issued or repaid, whichever applicable (or if not on a day on which LBMA is publishing prices, the closest preceding such day). Notwithstanding the foregoing, the Issuer may, in its sole discretion, select a different pricing source and time for determining the spot price of gold for operational purposes.\n"
        "2. **Payment**. All payments of principal and interest under this Token-Note will be denominated in gold, priced at the Spot Price, and paid in a U.S. dollar-denominated stablecoin selected by the Issuer, without offset, deduction, or counterclaim. Delivery shall be made in accordance with the procedures of the Token Platform, to the Holder, upon the Holder's valid exercise of its right to payment and redemption.\n"
        "3. **Demand**. The principal amount of this Token-Note, together with any and all accrued and unpaid interest thereon, is payable by the Issuer to the Holder **ON DEMAND** at any time by the Holder. Procedures for presentment are published on the Issuer's website [**app.tenbin.xyz**] and subject to all terms, conditions, and agreements published therein. Only after Holder is qualified and approved by the Issuer may it present this Token-Note for payment. Upon approval, and Holder's demand for payment via the Token Platform, the Issuer shall promptly deliver the specified amount represented by the Token, together with any and all accrued and unpaid interest, in accordance with the procedures of the Issuer Platform.\n"
        "4. **Interest**. Interest on the unpaid principal balance of this note, if any, is payable from the date of this Token-Note until this Note is paid in full, at amounts selected by the Issuer in its sole and absolute discretion. Accrued interest, if any, will be computed on the basis of a 365-day or 366-day year, as the case may be, based on the actual number of days elapsed in the period in which it accrues. For the avoidance of doubt, any interest payable under this note is at the sole and absolute discretion of the Issuer.\n"
        "5. **Waiver of Presentment; Demand**. The Issuer hereby waives presentment, demand, notice of dishonor, notice of default or delinquency, notice of protest and nonpayment, notice of costs, expenses or losses and interest on those, notice of interest on interest and late charges, and diligence in taking any action to collect any sums owing under this Note, including (to the extent permitted by law) waiving the pleading of any statute of limitations as a defense to any demand against the undersigned. Acceptance by the Holder this Note of any payment differing from the designated lump-sum payment listed above does not relieve the undersigned of the obligation to honor the requirements of this Note.\n"
        "6. **Governing Law**. The seat of administration, exclusive venue, and forum for any dispute, proceeding, or enforcement action relating to the Token or this Token-Note shall be the British Virgin Islands. Notwithstanding the foregoing, all rights and obligations arising under this Token-Note, including but not limited to all transfers, payments, and redemptions, shall be governed by and construed in accordance with Article 12 of the Uniform Commercial Code as adopted in the State of Delaware.\n"
        "7. **CER and Transfer**. The Holder's rights to payment and redemption under this Token-Note are evidenced by, and may be transferred only by, Token Control of the Token-Note as a CER. The Holder shall be deemed to have \"control\" of this Token-Note within the meaning of UCC Sec.12-105 if Holder has, as evidenced by the records of the Token Platform, the exclusive power to: (a) avail itself of substantially all the benefit from the Token-Note; (b) prevent others from availing themselves of substantially all the benefit of the Token-Note; and (c) transfer control of the Token-Note to another person. Upon cryptographic verification of the transfer on the applicable distributed ledger, ownership of the corresponding Note automatically passes to the transferee, and the transferee shall be a \"Holder\" hereunder as party to this Note. Upon transfer of a Token in accordance with this **Section 7** (such transferring Holder, the \"**Transferring Holder**\"), the Transferring Holder shall, as of the effective time of such disposition, automatically cease to be a party to this Note. For the avoidance of doubt, upon such transfer, all rights, benefits, duties, and obligations of such Transferring Holder under this Agreement shall immediately and irrevocably terminate, and such Transferring Holder shall not be entitled to any payments, indemnities, or other benefits hereunder, nor shall such Transferring Holder have any further liability or responsibility under this Note.\n\n"
        "Issuer, Initial Holder, and each other Holder agree and acknowledge:\n\n"
        "(a) The Token constitutes a CER and is subject to Token Control.\n\n"
        "(b) Token Control of the Token by a Holder is conclusive evidence of the ownership of the Note and the right to payment made hereunder. No separate register of holders shall be maintained by Issuer, Initial Holder or any other person.\n\n"
        "(c) Issuer further agrees (i) that the Note issued hereunder constitutes either (x) a controllable payment intangible (as defined in UCC Sec.9-102(a)(27B)), or (y) a controllable account (as defined in UCC Sec. 9-102(a)(27A)), as applicable, evidenced by (and tethered to) the Token issued pursuant to this Note, and (ii) agrees to pay the Holder who has Token Control over such Token in accordance with this Note. THE RIGHTS AND OBLIGATIONS DESCRIBED IN THIS TOKEN-NOTE ARE EMBODIED IN AND INSEPARABLE FROM THE TOKEN, SUCH THAT CONTROL OF THE TOKEN CONSTITUTES CONTROL OF THIS TOKEN-NOTE AND ALL RIGHTS HEREUNDER. Except as expressly permitted in this **Section 7**, no Holder may transfer its Token or the Note.\n\n"
        "8. **Severability**. If any one or more of the provisions contained in this Note is, for any reason, held to be invalid, illegal, or unenforceable in any respect, that invalidity, illegality, or unenforceability will not affect any other provisions of this Note, and this Note will be construed as if those invalid, illegal, or unenforceable provisions had never been contained in it, unless the deletion of those provisions would result in such a material change so as to cause completion of the transactions contemplated by this Note to be unreasonable.\n"
        "9. **Waiver; Amendment**. No amendment to the terms of this Note or waiver of a breach, failure of any condition, or any right or remedy contained in or granted by the provisions of this Note will be effective unless it is in writing and expressly approved by Issuer. No waiver of any breach, failure, right, or remedy will be deemed a waiver of any other breach, failure, right, or remedy, whether or not similar, and no waiver will constitute a continuing waiver, unless the writing so specifies.\n"
        "10. **Headings**. The descriptive headings of the sections and subsections of this Note are for convenience only, and do not affect this Note's construction or interpretation.\n"
        "11. **Platform-Based Signatures**. By issuing and accepting the Token on the Token Platform in accordance with Section 7 hereof, Issuer and each Holder authenticates, signs (including, without limitation, \"signing\" within the meaning of Section 1-201 of the UCC, and, for the avoidance of doubt, such signing shall constitute, without limitation, an \"electronic signature\" within the meaning of the Uniform Electronic Transactions Act and U.S. federal E-SIGN Act of 2000), executes, and delivers this Note as of the effective date of such acceptance. No manual signature, writings, notarization, or further action is required to indicate such Loan Participant's intent to authenticate or adopt this Agreement. In accordance with Section 6 hereof, this Agreement may be executed in any number of counterparts and all of such counterparts shall together constitute one and the same instrument.";

/**
 * @dev https://eips.ethereum.org/EIPS/eip-712[EIP-712] is a standard for hashing and signing of typed structured data.
 *
 * The encoding scheme specified in the EIP requires a domain separator and a hash of the typed structured data, whose
 * encoding is very generic and therefore its implementation in Solidity is not feasible, thus this contract
 * does not implement the encoding itself. Protocols need to implement the type-specific encoding they need in order to
 * produce the hash of their typed data using a combination of `abi.encode` and `keccak256`.
 *
 * This contract implements the EIP-712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
 * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
 * ({_hashTypedDataV4}).
 *
 * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
 * the chain id to protect against replay attacks on an eventual fork of the chain.
 *
 * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
 * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
 *
 * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
 * separator of the implementation contract. This will cause the {_domainSeparatorV4} function to always rebuild the
 * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.

/**
 * @dev Interface of the ERC-20 Permit extension allowing approvals to be made via signatures, as defined in
 * https://eips.ethereum.org/EIPS/eip-2612[ERC-2612].
 *
 * Adds the {permit} method, which can be used to change an account's ERC-20 allowance (see {IERC20-allowance}) by
 * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
 * need to send a transaction, and thus is not required to hold Ether at all.
 *
 * ==== Security Considerations
 *
 * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
 * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
 * considered as an intention to spend the allowance in any specific way. The second is that because permits have
 * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
 * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
 * generally recommended is:
 *
 * ```solidity
 * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
 *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
 *     doThing(..., value);
 * }
 *
 * function doThing(..., uint256 value) public {
 *     token.safeTransferFrom(msg.sender, address(this), value);
 *     ...
 * }
 * ```
 *
 * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
 * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
 * {SafeERC20-safeTransferFrom}).
 *
 * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
 * contracts should have entry points that don't rely on permit.
