How To Use Presto with viem.sh

To use Presto with viem.sh library using a custom RPC endpoint, follow these steps:

1. Install the viem.sh library by running npm install viem.sh in your project directory.

2. Create your rollup (How to Create a Rollup), open it, and get the RPC URL (What Is RPC).

   
3. Set up a provider to connect to your Presto L2 network using your custom RPC endpoint.

4. Make sure to replace YOUR_CUSTOM_RPC_ENDPOINT with the URL of your custom RPC endpoint.

const { viem } = require('viem.sh');

const provider = new viem.providers.JsonRpcProvider('YOUR_CUSTOM_RPC_ENDPOINT');

async function getBlockByNumber(blockNumber) {
  try {
    const block = await provider.getBlock(blockNumber);
    console.log(block);
  } catch (error) {
    console.log(error);
  }
}

getBlockByNumber(12345);
