  from: wallet[0].address,
  data: '0x61bc221a'
}
let callResult = await web3.eth.call(tx);
console.log(callResult);

let estimateGasResult = await web3.eth.estimateGas(tx);
console.log(estimateGasResult);

let sentTxReceipt = await web3.eth.sendTransaction(tx, undefined, {
  checkRevertBeforeSending: false,
});
console.log(sentTxReceipt);

Interacting with a Smart Contract

import { Web3, DEFAULT_RETURN_FORMAT } from "web3";

const web3 = new Web3("https://json-rpc.testnet.swisstronik.com/"); // Any RPC node you wanted to connect with
web3.registerPlugin(new SwisstronikPlugin());
let wallet = web3.eth.accounts.wallet.add("0x..."); // Private Key

const contract = new web3.eth.Contract(abi, ERC20_CONTRACT_ADDRESS);

const balanceOf = await contract.methods
  .balanceOf(wallet[0].address)
  .call();
console.log(balanceOf);

const gas = await contract.methods
  .transfer(wallet[0].address, 5n)
  .estimateGas({ from: wallet[0].address });
console.log(gas);

const sentTxReceipt = await contract.methods.transfer(wallet[0].address, 5n).send({from: wallet[0].address});
console.log(sentTxReceipt);

Connecting Accounts to Web3

import { Web3 } from "web3";
import { SwisstronikPlugin } from "@swisstronik/web3-plugin-swisstronik";

// With any RPC node and private key
const web3 = new Web3("https://json-rpc.testnet.swisstronik.com/");
const wallet = web3.eth.accounts.wallet.add("0x..."); // Private Key
const { address: account } = wallet[0];

// or with browser wallets
const web3 = new Web3(window.ethereum);
const [account] = await window.ethereum.request({
  method: "eth_requestAccounts"
});

web3.registerPlugin(new SwisstronikPlugin("https://json-rpc.testnet.swisstronik.com/"));
