Using web3.js with a custom RPC endpoint allows you to interact with your Presto L2 and perform various operations on the network. You can retrieve information like the latest block number, check balance, and send transactions.
To use web3.js with a custom RPC endpoint, you can follow the steps below:
constrpcEndpoint='<RPC URL from the chain>'; // Replace with your custom RPC endpointconstweb3=newWeb3(rpcEndpoint);
Use web3.js methods to interact with your local geth node:
// Get the latest block numberweb3.eth.getBlockNumber().then(blockNumber => {console.log('Latest Block Number:', blockNumber); }).catch(error => {console.error('Error:', error); });// Get balance of an addressconstaddress='0x1234567890abcdef...'; // Replace with the desired addressweb3.eth.getBalance(address).then(balance => {console.log('Balance of', address +':', balance); }).catch(error => {console.error('Error:', error); });// Send a transactionconstfrom='0x9876543210fedcba...'; // Replace with the sender's addressconstto='0xabcdef1234567890...'; // Replace with the recipient's addressconstvalue=web3.utils.toWei('1','ether'); // Replace with the desired valueweb3.eth.sendTransaction({ from, to, value }).then(transactionHash => {console.log('Transaction Hash:', transactionHash); }).catch(error => {console.error('Error:', error); });
Remember to replace the placeholders with your own values.
