How to use Japan Open Chain Testnet RPC Endpoint

You can use the Japan Open Chain Testnet 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 Japan Open Chain Testnet

Web3 libraries

web3js

   const Web3 = require('web3');

   // Replace 'YOUR_RPC_URL' with the Japan Open Chain Testnet RPC endpoint URL
   const rpcURL = https://rpc-1.testnet.japanopenchain.org:8545;

   // 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 Japan Open Chain Testnet
   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 Japan Open Chain Testnet RPC endpoint URL
   const rpcURL = https://rpc-1.testnet.japanopenchain.org:8545;

   // Create a provider using the Japan Open Chain Testnet RPC endpoint
   const provider = new ethers.providers.JsonRpcProvider(rpcURL);

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