dapp/defi/lp流動性質押挖礦分紅系統開發(開發規則)丨詳細及原始碼

xiaofufu發表於2023-04-08

  Web3.0推動分散式經濟模型的實現,如NFT、Defi、加密貨幣和去中心化自治組織(DAO)。Web3.0共建共享的特性,與Web2.0中使用者僅作為使用者不同,使Web3.0中使用者能主動參與共建與共治,以DAO的組織形式,利用區塊鏈技術和智慧合約進行規則制定與執行,共擔共享平臺或協議的價值。


  關於區塊鏈專案技術開發唯:MrsFu123,代幣發行、dapp智慧合約開發、鏈遊開發、單雙幣質押、多鏈錢包開發、NFT盲盒遊戲、公鏈、鏈上游戲開發


  Uniswap博餅、交易所開發、量化合約開發、合約對沖、互助遊戲開發、Nft數字藏品開發、眾籌互助開發、元宇宙開發、swap開發、DAO智慧合約、


  夾子合約、鏈上合約開發、ido開發、商城開發等,開發過各種各樣的系統模式,更有多種模式、制度、案例、後臺等,成熟技術團隊,歡迎實體參考。


  DeFi mining is also known as liquidity mining,and more commonly,it involves providing/pledging tokens to receive rewards from other tokens.


  Liquidity mining is an incentive mechanism to promote the use of DeFi and a new decentralized token distribution mechanism.Most DeFi applications require users to lock tokens into contracts,and the larger the amount of lock in the contract,the better financial services can be obtained.Liquidity mining will incentivize users to provide LP for DeFi applications,while the newly issued tokens of the product will distribute different amounts of tokens to users based on their lock-in contribution.


  公鏈是Web3.0的核心載體,支援互操作、賦權賦能和信用機制,以及各類應用,Web3.0公鏈賽道主要包括Layer1、Layer2、Layer0。


  區塊鏈技術由此可以從多方面為企業賦能:開發詳細:I35原始碼7O98案例O7I8提供可靠的共享資料,在各方之間建立信任;消除資料孤島,即透過去中心化的,在一個網路並支援獲許可方訪問的賬本將資料整合到一個系統中;為資料賦予高度安全性


  function _addLiquidity(


  address tokenA,


  address tokenB,


  uint amountADesired,


  uint amountBDesired,


  uint amountAMin,


  uint amountBMin


  )internal virtual returns(uint amountA,uint amountB){


  if(IUniswapV2Factory(factory).getPair(tokenA,tokenB)==address(0)){


  IUniswapV2Factory(factory).createPair(tokenA,tokenB);


  }


  (uint reserveA,uint reserveB)=UniswapV2Library.getReserves(factory,tokenA,tokenB);


  if(reserveA==0&&reserveB==0){


  (amountA,amountB)=(amountADesired,amountBDesired);


  }else{


  uint amountBOptimal=UniswapV2Library.quote(amountADesired,reserveA,reserveB);


  if(amountBOptimal<=amountBDesired){


  require(amountBOptimal>=amountBMin,'UniswapV2Router:INSUFFICIENT_B_AMOUNT');


  (amountA,amountB)=(amountADesired,amountBOptimal);


  }else{


  uint amountAOptimal=UniswapV2Library.quote(amountBDesired,reserveB,reserveA);


  assert(amountAOptimal<=amountADesired);


  require(amountAOptimal>=amountAMin,'UniswapV2Router:INSUFFICIENT_A_AMOUNT');


  (amountA,amountB)=(amountAOptimal,amountBDesired);


  }


  }


  }
