How to use Harmony Mainnet Shard 1 RPC Endpoint

You can use the Harmony Mainnet Shard 1 RPC Endpoint to connect with Web3 libraries like Ethers.js, Web3, or Web3 wallets like MetaMask, WalletConnect, WalletConnect. This allows you to easily interact with blockchain and use decentralized applications on the Harmony Mainnet Shard 1

Web3 libraries

web3js

   const Web3 = require('web3');

   // Replace 'YOUR_RPC_URL' with the Harmony Mainnet Shard 1 RPC endpoint URL
   const rpcURL = https://s1.api.harmony.one;

   // 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 Harmony Mainnet Shard 1
   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 Harmony Mainnet Shard 1 RPC endpoint URL
   const rpcURL = https://s1.api.harmony.one;

   // Create a provider using the Harmony Mainnet Shard 1 RPC endpoint
   const provider = new ethers.providers.JsonRpcProvider(rpcURL);

   // You can use the 'provider' object to interact with Harmony Mainnet Shard 1
   provider.getBlockNumber()
      .then(blockNumber => {
         console.log('Latest block number:', blockNumber);
      })
      .catch(error => {
         console.error('Error:', error);
      });
