如何使用 Arbitrum One RPC端点

您可以使用 Arbitrum One RPC端点 您可以使用以太坊主网的RPC端点URL与Web3库（如Ethers.js、Web3）或Web3钱包（如MetaMask、WalletConnect、WalletConnect）建立连接。这使您能够轻松地与区块链进行交互并使用去中心化应用程序。 Arbitrum One

Web3库

web3js

   const Web3 = require('web3');

   // Replace 'YOUR_RPC_URL' with the Arbitrum One RPC endpoint URL
   const rpcURL = https://arbitrum.llamarpc.com;

   // Create a new Web3 instance using the RPC endpoint
   const web3 = new Web3(new Web3.providers.HttpProvider(rpcURL));

   // Now you can use the 'web3' object to interact with Arbitrum One
   web3.eth.getBlockNumber()
      .then(blockNumber => {
         console.log('Latest block number:', blockNumber);
      })
      .catch(error => {
         console.error('Error:', error);
      });
   

ethersjs

   const ethers = require('ethers');

   // Replace 'YOUR_RPC_URL' with the Arbitrum One RPC endpoint URL
   const rpcURL = https://arbitrum.llamarpc.com;

   // Create a provider using the Arbitrum One RPC endpoint
   const provider = new ethers.providers.JsonRpcProvider(rpcURL);

   // You can use the 'provider' object to interact with Arbitrum One
   provider.getBlockNumber()
      .then(blockNumber => {
         console.log('Latest block number:', blockNumber);
      })
      .catch(error => {
         console.error('Error:', error);
      });
