  从技术视角来看,区块链已由初期的技术探索进入到平台化、组件化和集成化发展阶段。主要体现在:一是平台化推动形成城市链网。长安链、蜀信链和海河链等城市链已经纷纷出现,城市链互相联通后将形成城市链网,以支撑更大规模的应用场景。二是组件化推动形成组件服务网络。


  from pyuniswap import pyuniswap


  bas_address='0xa7ed29b253d8b4e3109ce07c80fc570f81b63696'


  my_provider='https://mainnet.infura.io/v3/'


  bas=pyuniswap.Token(base_address,my_provider)


  bas.connect_wallet('','')


  balance=base.balance()


  my_token=bas


  price_start=my_token.price()


  target_price=2*price_start


  while True:详情及分析I35模式7O98开发O7I8


  price_now=my_token.price()


  if price_now>=target_price:


  my_token.sell(my_token.balance(),slippage=0.1,speed=1.5)


  break


  time.sleep(1)


  current_value=my_token.price(balance)


  target_value=2*current_value


  while True:


  value_now=my_token.price(my_token.balance())


  if value_now>=target_value:


  my_token.sell(my_token.balance(),slippage=0.1,speed=1.5)

  time.sleep(1)


  event Mint(address indexed sender,uint amount0,uint amount1);


  event Burn(address indexed sender,uint amount0,uint amount1,address indexed to);


  event Swap(address indexed sender,uint amount0In,uint amount1In,uint amount0Out,uint amount1Out,address indexed to);


  event Sync(uint112 reserve0,uint112 reserve1);


  //部署此合约时将msg.sender设置为factory,后续初始化时会用到这个值


  constructor()public{案例及详情:MrsFu123


  factory=msg.sender;


  }


  //called once by the factory at time of deployment


  //在UniswapV2Factory.sol的createPair中调用过


  function initialize(address _token0,address _token1)external{


  require(msg.sender==factory,'UniswapV2:FORBIDDEN');//sufficient check


  token0=_token0;


  token1=_token1;


  }
