+
+## Methods
+
+### authorizeOperator
+
+:::note Links
+
+- Specification details in [**LSP-7-Burnable**](https://github.com/lukso-network/lips/tree/main/LSPs/LSP-7-Burnable.md#authorizeoperator)
+- Solidity implementation in [**LSP7Burnable**](https://github.com/lukso-network/lsp-smart-contracts/blob/develop/contracts/LSP7Burnable)
+- Function signature: `authorizeOperator(address,uint256)`
+- Function selector: `0x47980aa3`
+
+:::
+
+:::danger
+
+To avoid front-running and Allowance Double-Spend Exploit when increasing or decreasing the authorized amount of an operator, it is advised to: 1. either call {revokeOperator} first, and then re-call {authorizeOperator} with the new amount. 2. or use the non-standard functions {increaseAllowance} or {decreaseAllowance}. For more information, see: https://docs.google.com/document/d/1YLPtQxZu1UAvO9cZ1O2RPXBbT0mooh4DYKjA_jp-RLM/
+
+:::
+
+```solidity
+function authorizeOperator(
+  address operator,
+  uint256 amount
+) external nonpayable;
+```
+
+Sets an `amount` of tokens that an `operator` has access from the caller's balance (allowance). See [`authorizedAmountFor`](#authorizedamountfor).
+
+#### Parameters
+
+| Name       |   Type    | Description                                            |

+This is a non-standard function, not part of the LSP7 standard interface. It has been added in the LSP7 contract implementation so that it can be used as a prevention mechanism against double spending allowance vulnerability.
+
+:::
+
+```solidity
+function increaseAllowance(
+  address operator,
+  uint256 addedAmount
+) external nonpayable;
+```
+
+_Increase the allowance of `operator` by +`addedAmount`_
+
+Atomically increases the allowance granted to `operator` by the caller. This is an alternative approach to [`authorizeOperator`](#authorizeoperator) that can be used as a mitigation for the double spending allowance problem.
+
+<blockquote>

-[`LSP9Vault.sol`](https://github.com/lukso-network/lsp-smart-contracts/blob/main/contracts/LSP9Vault/LSP9Vault.sol)
-
-:::
-
-The **LSP9Vault** contract is an implementation of the **[LSP9-Vault Standard](#)**.
-
-This contract can be used as a **vault** that can **hold assets** and **interact with other smart contracts**, as it has all the functions of the **[LSP0ERC725Account](./lsp0-erc725-account.md)** contract, except for the **`isValidSignature(...)`** function.
-
-:::note
-_LSP9Vault contract also contains the methods from the [ERC165 Standard](https://eips.ethereum.org/EIPS/eip-165):_
-
-```solidity
-function supportsInterface(bytes4 interfaceId) public view returns (bool)
-```

-## Functions
-
-### constructor
-
-```solidity
-constructor(address initialOwner)
-```
-
-Sets the **initial owner** of the contract, the **[SupportedStandards:LSP9Vault ](#)** data key in the vault storage.
-
-If the `initialOwner` is an **[LSP0ERC725Account](./lsp0-erc725-account.md)** contract, the **[`universalReceiver(...)`](./lsp0-erc725-account.md#universalreceiver)** function will be called on the **LSP0ERC725Account** contract to inform the account about the **newly owned vault**.
-
-#### Parameters:
-
-| Name           | Type      | Description                                      |
-| :------------- | :-------- | :----------------------------------------------- |
-| `initialOwner` | `address` | The address to set as the owner of the contract. |
-
-### owner
-
-```solidity
-function owner() public view returns (address owner)
-```
-
-Returns the address of the current vault owner.
-
-#### Return Values:
-
-| Name    | Type      | Description                     |
-| :------ | :-------- | :------------------------------ |
-| `owner` | `address` | The current owner of the vault. |
-
-### pendingOwner
-
-```solidity
-function pendingOwner() public view returns (address)
-```
-
-Return the address of the pending owner that was initiated by [`transferOwnership(address)`](#transferownership).
-
-> **NB:** if no ownership transfer is in progress, the `pendingOwner` MUST be `address(0)`.
-
-#### Return Values:
-
-| Name           | Type      | Description                      |
-| :------------- | :-------- | :------------------------------- |
-| `pendingOwner` | `address` | The address of the pending owner |
-
-### transferOwnership
-
-```solidity
-function transferOwnership(address newOwner) public
-```
-
-Initiate an ownership transfer by setting the `newOwner` as `pendingOwner`.
-
-Requirements:
-
-- Can only be called by the current owner.
-- The `newOwner` to be set as the `pendingOwner` cannot be `address(this)`.
-
-#### Parameters:
-
-| Name       | Type      | Description                           |
-| :--------- | :-------- | :------------------------------------ |
-| `newOwner` | `address` | The address to set as `pendingOwner`. |
-
-### acceptOwnership
-
-```solidity
-function acceptOwnership() public
-```
-
-Transfers ownership of the contract to the `pendingOwner` address. Can only be called by the `pendingOwner`.
-
-_Triggers the **[OwnershipTransferred](#ownershiptransferred)** event once the new owner has claimed ownership._
-
-### renounceOwnership
-
-```solidity
-function renounceOwnership() public
-```
-
-Since renouncing ownership is a sensitive operation, it is done as a two step process by calling `renounceOwnership(..)` twice. First to initiate the process, second as a confirmation.
-
-The current block number is saved as a part of initiation because the following behaviour is wanted:
-
-- The first 100 blocks after the saved block is the pending period, if you call `renounceOwnership(..)` during this period, the transaction will be reverted.
-- the following 100 blocks is the period when you can confirm the renouncement of the contract by calling `renounceOwnership(..)` the second time.
-
-_Triggers the **[RenounceOwnershipInitiated](#renounceownershipinitiated)** event in the first call._
-
-_Triggers the **[OwnershipTransferred](#ownershiptransferred)** event after successfully renouncing ownership._
-
-:::warning
-Leaves the contract without an owner. Once ownership of the contract is renounced, it won't be possible to call the functions restricted to the owner only.
-:::
-
-### fallback
-
-```solidity
-fallback() external payable
-```
-
-Executed when value is transferred to the contract or when function identifier doesn't match any of the available functions.
-
-_Triggers the **[ValueReceived](#valuereceived)** event when a native token is received._
-
-### execute
-
-```solidity
-function execute(
-    uint256 operationType,
-    address target,
-    uint256 value,
-    bytes memory data
-) public payable returns (bytes memory result)
-```
-
-Executes a call on any other smart contracts, transfers value, or deploys a new smart contract.
-
-The following `operationType` MUST exist:
-
-- `0` for `CALL`
-- `1` for `CREATE`
-- `2` for `CREATE2`
-- `3` for `STATICCALL`
-
-_Triggers the **[Executed](#executed)** event when a call is successfully executed using `CALL/STATICCALL` operations._
-
-_Triggers the **[ContractCreated](#contractcreated)** event when a smart contract is created using `CREATE/CREATE2` operations._
-
-:::note
-The `execute(...)` function can only be called by the current owner of the vault.
-
-The operation type `staticcall` (`3`) does not allow to transfer value.
