Farming contracts
About
这个存储库提供了 2 种耕作方式（奖励）。 强烈建议通过从 ERC20Farmable 智能合约派生它们来使用池/共享/实用程序令牌的第二个选项。 如果为时已晚，您还应该考虑第一个选项：
FarmingPool.soloffers smart contract where you can stake/deposit specific tokens to get continiously distributed rewards.ERC20Farmable.solallows derived tokens to have farming without necessarity to stake/deposit token into pool. Moreover it allows to have multiple farmings simultaneously and setup new farms permissionlessly.
Installation
!!! NOTICE: WAIT UNTILL FULLY AUDITED !!!
$ npm install @1inch/farming
或者
$ yarn add @1inch/farming
Usage

安装后，您可以通过导入来使用库中的合同。 只需使用 ERC20Farmable 而不是 ERC20 来派生自：
pragma solidity ^0.8.0;
import "@1inch/farming/contracts/ERC20Farmable.sol";
contract AMMPoolToken is ERC20Farmable {
constructor() ERC20("AMMPoolToken", "AMM") {
}
}

存储访问：
1 个用于农业参数的存储槽，仅在农业重启时更新： <代码>坚固性 uint40 公共完成； uint32 公共持续时间； uint184 公共奖励；
1 个存储槽 用于农业状态，已更新仅在改变农业代币数量时： <代码>坚固性 uint40 公共检查点； uint216 public farmedPerTokenStored；
每个农民有 1 个存储位，根据存款更新/withdrawals（感谢 @snjax）：
mapping(address => int256) public corrections;
紧凑的地址数组用于存储每个用户/钱包的农场。 数组长度存储在第一个数组项的高位：

About
This repository offers 2 ways to have farming (incentives). Highly recommend to use second option for pools/share/utility tokens by deriving them from ERC20Farmable smart contract. If it's too late you should consider first option as well:
FarmingPool.soloffers smart contract where you can stake/deposit specific tokens to get continiously distributed rewards.ERC20Farmable.solallows derived tokens to have farming without necessarity to stake/deposit token into pool. Moreover it allows to have multiple farmings simultaneously and setup new farms permissionlessly.

Once installed, you can use the contracts in the library by importing them. Just use ERC20Farmable instead of ERC20 to derive from:
pragma solidity ^0.8.0;
import "@1inch/farming/contracts/ERC20Farmable.sol";
contract AMMPoolToken is ERC20Farmable {
constructor() ERC20("AMMPoolToken", "AMM") {
}
}

Storage access:
1 storage slot for farming params, updated only on farming restarting:
solidity uint40 public finished; uint32 public duration; uint184 public reward;1 storage slot for farming state, updated only on changing number of farming tokens:
solidity uint40 public checkpoint; uint216 public farmedPerTokenStored;1 storage slot per each farmer, updated on deposits/withdrawals (kudos to @snjax):
mapping(address => int256) public corrections;
Compact address array is used for storing farms per user/wallet. Array length is stored in high bits of the first array item:
