Quick Start

You can interact with a Tanssi EVM appchain using standard Ethereum libraries, like Ethers.js, Web3.js, and To quickly get started, you'll need to create a provider connected to a Tanssi EVM appchain:

import { ethers } from "ethers";

const providerRPC = {
  evmAppchain: {
    name: 'dancebox-evm-appchain',
    // Insert your RPC URL here
    rpc: '', 
    chainId: 5678, // 0x162E in hex,
const provider = new ethers.JsonRpcProvider(
    chainId: providerRPC.evmAppchain.chainId,
const Web3 = require('web3');

const web3 = new Web3(
from web3 import Web3

web3 = Web3(Web3.HTTPProvider(''))
