Building dApps on Tetreum: A Developer's Complete Guide

If you've built on Ethereum, Polygon, or BNB Chain before, you already know how to build on Tetreum. Our full EVM compatibility means zero re-learning — just point your existing tools at our RPC and start deploying.

Prerequisites

• Node.js 18+ installed
• MetaMask browser extension
• Hardhat or Foundry project set up
• Basic Solidity knowledge

Step 1: Connect to Tetreum Testnet

Network Name: Tetreum Testnet
RPC URL: https://testrpc.tetreum.com
Chain ID: 793788
Currency: TET
Explorer: https://testnet.tetscan.com

Step 2: Configure Hardhat

import { HardhatUserConfig } from "hardhat/config";

const config: HardhatUserConfig = {
  solidity: "0.8.24",
  networks: {
    tetreum_testnet: {
      url: "https://testrpc.tetreum.com",
      chainId: 793788,
      accounts: [process.env.PRIVATE_KEY!],
    },
  },
};

export default config;

Step 3: Deploy Your Contract

npx hardhat run scripts/deploy.ts --network tetreum_testnet

Step 4: Connect Your Frontend with wagmi

import { defineChain } from "viem";

export const tetreumTestnet = defineChain({
  id: 793788,
  name: "Tetreum Testnet",
  nativeCurrency: { name: "TET", symbol: "TET", decimals: 18 },
  rpcUrls: {
    default: { http: ["https://testrpc.tetreum.com"] },
  },
  blockExplorers: {
    default: { name: "TetScan", url: "https://testnet.tetscan.com" },
  },
});

"The best Tetreum dApps are architecturally simple at the contract level and rich at the frontend. Our parallelism does the heavy lifting — your contract just needs to be correct." — Tetreum DevRel
