By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

When this value is equal to type(uint256).max, it is\n *  a request by the user to use the intra-transaction delta of the specified\n *  token as the specified amount.  See LibBalanceDelta for more information\n *  about this.  When the Ocean executes an interaction, it resolves the\n *  specifiedAmount before calling the external contract.  During a \"721\"\n *  interaction, the resolved specifiedAmount must be identically \"1\".\n * @param metadata This value is used in two ways.  During \"Compute\"\n *  interactions, it is forwarded to the external contract.  The external\n *  contract can define whatever expectations it wants for these 32 bytes.  The\n *  caller is expected to be aware of the expectations of the external contract\n *  invoked during the interaction.  During 721/1155 and wraps and unwraps,\n *  these bytes are cast to uint256 and used as the external ledger's token ID\n *  for the interaction.\n */\nstruct Interaction {\n    bytes32 interactionTypeAndAddress;\n    uint256 inputToken;\n    uint256 outputToken;\n    uint256 specifiedAmount;\n    bytes32 metadata;\n}\n\n/**\n * InteractionType determines how the properties of Interaction are interpreted\n *\n * The interface implemented by the external contract, the specified token\n *  for the interaction, and what sign (+/-) of delta can be used are\n *  determined by the InteractionType.\n *\n * @param WrapErc20\n *      type(externalContract).interfaceId == IERC20\n *      specifiedToken == calculateOceanId(externalContract, 0)\n *      negative delta can be used as specifiedAmount\n *\n * @param UnwrapErc20\n *      type(externalContract).interfaceId == IERC20\n *      specifiedToken == calculateOceanId(externalContract, 0)\n *      positive delta can be used as specifiedAmount\n *\n * @param WrapErc721\n *      type(externalContract).interfaceId == IERC721\n *      specifiedToken == calculateOceanId(externalContract, metadata)\n *      negative delta can be used as specifiedAmount\n *\n * @param UnwrapErc721\n *      type(externalContract).interfaceId == IERC721\n *      specifiedToken == calculateOceanId(externalContract, metadata)\n *      positive delta can be used as specifiedAmount\n *\n * @param WrapErc1155\n *      type(externalContract).interfaceId == IERC1155\n *      specifiedToken == calculateOceanId(externalContract, metadata)\n *      negative delta can be used as specifiedAmount\n *\n * @param WrapErc1155\n *      type(externalContract).interfaceId == IERC1155\n *      specifiedToken == calculateOceanId(externalContract, metadata)\n *      positive delta can be used as specifiedAmount\n *\n * @param ComputeInputAmount\n *      type(externalContract).interfaceId == IOceanexternalContract\n *      specifiedToken == outputToken\n *      negative delta can be used as specifiedAmount\n *\n * @param ComputeOutputAmount\n *      type(externalContract).interfaceId == IOceanexternalContract\n *      specifiedToken == inputToken\n *      positive delta can be used as specifiedAmount\n */\nenum InteractionType {\n    WrapErc20,\n    UnwrapErc20,\n    WrapErc721,\n    UnwrapErc721,\n    WrapErc1155,\n    UnwrapErc1155,\n    ComputeInputAmount,\n    ComputeOutputAmount,\n    UnwrapEther\n}\n\ninterface IOceanInteractions {\n    function unwrapFeeDivisor() external view returns (uint256);\n\n    function doMultipleInteractions(Interaction[] calldata interactions, uint256[] calldata ids) external payable returns (uint256[] memory burnIds, uint256[] memory burnAmounts, uint256[] memory mintIds, uint256[] memory mintAmounts);\n\n    function forwardedDoMultipleInteractions(\n        Interaction[] calldata interactions,\n        uint256[] calldata ids,\n        address userAddress\n    )\n        external\n        payable\n        returns (uint256[] memory burnIds, uint256[] memory burnAmounts, uint256[] memory mintIds, uint256[] memory mintAmounts);\n\n    function doInteraction(Interaction calldata interaction) external payable returns (uint256 burnId, uint256 burnAmount, uint256 mintId, uint256 mintAmount);\n\n    function forwardedDoInteraction(Interaction calldata interaction, address userAddress) external payable returns (uint256 burnId, uint256 burnAmount, uint256 mintId, uint256 mintAmount);\n}\n"
