使用 Alchemy SDK 可以方便的让你的 dapp 与链上进行数据交互

1. 引入 sdk

   npm install alchemy-sdk
   
   import { Network, Alchemy } from 'alchemy-sdk';
   
   // Optional Config object, but defaults to demo api-key and eth-mainnet.
   const settings = {
     apiKey: 'demo', // Replace with your Alchemy API Key.
     network: Network.ETH_MAINNET, // Replace with your network.
   };
   
   const alchemy = new Alchemy(settings);
   

2. 使用 api 读取 nft 数据

   alchemy.nft.getNftsForOwner('vitalik.eth').then(res => {
     console.log(res);
   });
