+[![Docs](https://img.shields.io/badge/docs-%F0%9F%93%84-blue)](https://docs.openzeppelin.com/contracts)
+[![NPM Package](https://img.shields.io/npm/v/@openzeppelin/contracts.svg)](https://www.npmjs.org/package/@openzeppelin/contracts)
+[![Coverage Status](https://codecov.io/gh/OpenZeppelin/openzeppelin-contracts/graph/badge.svg)](https://codecov.io/gh/OpenZeppelin/openzeppelin-contracts)
+
+**A library for secure smart contract development.** Build on a solid foundation of community-vetted code.
+
+ * Implementations of standards like [ERC20](https://docs.openzeppelin.com/contracts/erc20) and [ERC721](https://docs.openzeppelin.com/contracts/erc721).
+ * Flexible [role-based permissioning](https://docs.openzeppelin.com/contracts/access-control) scheme.
+ * Reusable [Solidity components](https://docs.openzeppelin.com/contracts/utilities) to build custom contracts and complex decentralized systems.
+ * First-class integration with the [Gas Station Network](https://docs.openzeppelin.com/contracts/gsn) for systems with no gas fees!
+ * [Audited](https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/audit) by leading security firms (_last full audit on v2.0.0_).
+
+## Overview
+
+### Installation
+
+```console
+$ npm install @openzeppelin/contracts
+```
+
+OpenZeppelin Contracts features a [stable API](https://docs.openzeppelin.com/contracts/releases-stability#api-stability), which means your contracts won't break unexpectedly when upgrading to a newer minor version.
+
+### Usage
+
+Once installed, you can use the contracts in the library by importing them:
+
+```solidity
+pragma solidity ^0.8.0;
+
+import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
+
+contract MyCollectible is ERC721 {
+    constructor() ERC721("MyCollectible", "MCO") {
+    }
+}
+```
+
+_If you're new to smart contract development, head to [Developing Smart Contracts](https://docs.openzeppelin.com/learn/developing-smart-contracts) to learn about creating a new project and compiling your contracts._
+
+To keep your system secure, you should **always** use the installed code as-is, and neither copy-paste it from online sources, nor modify it yourself. The library is designed so that only the contracts and functions you use are deployed, so you don't need to worry about it needlessly increasing gas costs.
+
+## Learn More
+
+The guides in the [docs site](https://docs.openzeppelin.com/contracts) will teach about different concepts, and how to use the related contracts that OpenZeppelin Contracts provides:
+
+* [Access Control](https://docs.openzeppelin.com/contracts/access-control): decide who can perform each of the actions on your system.
+* [Tokens](https://docs.openzeppelin.com/contracts/tokens): create tradeable assets or collectives, and distribute them via [Crowdsales](https://docs.openzeppelin.com/contracts/crowdsales).
+* [Gas Station Network](https://docs.openzeppelin.com/contracts/gsn): let your users interact with your contracts without having to pay for gas themselves.
+* [Utilities](https://docs.openzeppelin.com/contracts/utilities): generic useful tools, including non-overflowing math, signature verification, and trustless paying systems.
+
+The [full API](https://docs.openzeppelin.com/contracts/api/token/ERC20) is also thoroughly documented, and serves as a great reference when developing your smart contract application. You can also ask for help or follow Contracts's development in the [community forum](https://forum.openzeppelin.com).
+
+Finally, you may want to take a look at the [guides on our blog](https://blog.openzeppelin.com/guides), which cover several common use cases and good practices.. The following articles provide great background reading, though please note, some of the referenced tools have changed as the tooling in the ecosystem continues to rapidly evolve.
+
+* [The Hitchhiker’s Guide to Smart Contracts in Ethereum](https://blog.openzeppelin.com/the-hitchhikers-guide-to-smart-contracts-in-ethereum-848f08001f05) will help you get an overview of the various tools available for smart contract development, and help you set up your environment.
+* [A Gentle Introduction to Ethereum Programming, Part 1](https://blog.openzeppelin.com/a-gentle-introduction-to-ethereum-programming-part-1-783cc7796094) provides very useful information on an introductory level, including many basic concepts from the Ethereum platform.
+* For a more in-depth dive, you may read the guide [Designing the Architecture for Your Ethereum Application](https://blog.openzeppelin.com/designing-the-architecture-for-your-ethereum-application-9cec086f8317), which discusses how to better structure your application and its relationship to the real world.
+
+## Security
+
+This project is maintained by [OpenZeppelin](https://openzeppelin.com), and developed following our high standards for code quality and security. OpenZeppelin is meant to provide tested and community-audited code, but please use common sense when doing anything that deals with real money! We take no responsibility for your implementation decisions and any security problems you might experience.
+
+The core development principles and strategies that OpenZeppelin is based on include: security in depth, simple and modular code, clarity-driven naming conventions, comprehensive unit testing, pre-and-post-condition sanity checks, code consistency, and regular audits.
+
+The latest audit was done on October 2018 on version 2.0.0.
+
+Please report any security issues you find to security@openzeppelin.org.

+ * {AccessControlEnumerable}.
+ *
+ * Roles are referred to by their `bytes32` identifier. These should be exposed

+ * using `public constant` hash digests:

+ *     ...
+ * }

+ *
+ * Roles can be granted and revoked dynamically via the {grantRole} and

+ * 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}.

+ * @dev This contract allows to split Ether payments among a group of accounts. The sender does not need to be aware
+ * that the Ether will be split in this way, since it is handled transparently by the contract.
+ *
+ * The split can be in equal parts or in any other arbitrary proportion. The way this is specified is by assigning each
+ * account to a number of shares. Of all the Ether that this contract receives, each account will then be able to claim
+ * an amount proportional to the percentage of total shares they were assigned.
+ *
+ * `PaymentSplitter` follows a _pull payment_ model. This means that payments are not automatically forwarded to the
+ * accounts but kept in this contract, and the actual transfer is triggered as a separate step by calling the {release}
+ * function.

+ * By default, this contract is self administered, meaning administration tasks

+ * @dev Implementation of the {IERC20} interface.
+ *
+ * This implementation is agnostic to the way tokens are created. This means
+ * that a supply mechanism has to be added in a derived contract using {_mint}.
+ * For a generic mechanism see {ERC20PresetMinterPauser}.
+ *
+ * TIP: For a detailed writeup see our guide
+ * https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
+ * to implement supply mechanisms].
+ *
+ * We have followed general OpenZeppelin guidelines: functions revert instead
+ * of returning `false` on failure. This behavior is nonetheless conventional
+ * and does not conflict with the expectations of ERC20 applications.
+ *
+ * Additionally, an {Approval} event is emitted on calls to {transferFrom}.
+ * This allows applications to reconstruct the allowance for all accounts just
+ * by listening to said events. Other implementations of the EIP may not emit
+ * these events, as it isn't required by the specification.
+ *
+ * Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
+ * functions have been added to mitigate the well-known issues around setting
+ * allowances. See {IERC20-approve}.

+/**
+ * @dev This contract extends an ERC20 token with a snapshot mechanism. When a snapshot is created, the balances and
+ * total supply at the time are recorded for later access.
+ *
+ * This can be used to safely create mechanisms based on token balances such as trustless dividends or weighted voting.
+ * In naive implementations it's possible to perform a "double spend" attack by reusing the same balance from different
+ * accounts. By using snapshots to calculate dividends or voting power, those attacks no longer apply. It can also be
+ * used to create an efficient ERC20 forking mechanism.
+ *
+ * Snapshots are created by the internal {_snapshot} function, which will emit the {Snapshot} event and return a
+ * snapshot id. To get the total supply at the time of a snapshot, call the function {totalSupplyAt} with the snapshot
+ * id. To get the balance of an account at the time of a snapshot, call the {balanceOfAt} function with the snapshot id
+ * and the account address.
+ *
+ * ==== Gas Costs
+ *
+ * Snapshots are efficient. Snapshot creation is _O(1)_. Retrieval of balances or total supply from a snapshot is _O(log
+ * n)_ in the number of snapshots that have been created, although _n_ for a specific account will generally be much
+ * smaller since identical balances in subsequent snapshots are stored as a single entry.
+ *
+ * There is a constant overhead for normal ERC20 transfers due to the additional snapshot bookkeeping. This overhead is
+ * only significant for the first transfer that immediately follows a snapshot for a particular account. Subsequent
+ * transfers will have normal cost until the next snapshot, and so on.
