Truffle dashboard

Truffle dashboard helps you to connect any application on your computer to the metamask in your favorite browser. When ran, it will create a webserver and deploys a website on localhost, using which you can connect your metamask wallet.

Connecting with ethers.js

The following code assumes that your truffle dashboard runs on the port 24012

import { ethers } from "ethers";

const DASHBOARD_PROVIDER_RPC = "http://localhost:24012/rpc"

async function main() {
  const provider = new ethers.providers.JsonRpcProvider(DASHBOARD_PROVIDER_RPC);

  const signer = provider.getSigner();

  const accounts = await provider.listAccounts();
  console.log(accounts);

  // do something with `signer` or `provider` ...
}

main()

Use the following code to get an instance of a smart contract

import { ethers } from "ethers";

const instance = new ethers.Contract(address, abi, signerOrProvider)

• For making calls, use either provider or signer
• For sending transactions, use signer

Are you using web3.js

Try the following (code not tested)

var provider = new Web3(new Web3.providers.HttpProvider('http://localhost:7545'));

Prefer using ethers.js
