World Mobile Chain API Quickstart

Don't have an API key?

Build faster with production-ready APIs, smart wallets and rollup infrastructure across 70+ chains. Create your free Alchemy API key and get started today.

World Mobile Chain is an EVM-compatible Layer-3 built on Base for decentralized telecom (DePIN), where EarthNodes secure the network and process telco data to deliver fast, low-cost onchain services.

The World Mobile Chain API allows interaction with the World Mobile Chain network through a set of JSON-RPC methods. Its design is familiar to developers who have worked with Ethereum's JSON-RPC APIs, making it intuitive and straightforward to use.

Let's use the viem package to create a World Mobile Chain client connected to Alchemy and fetch the latest block number!

npm install --save viem

import { createPublicClient, http, defineChain } from "viem";
 
const worldMobileChain = defineChain({
  id: 2049,
  name: "World Mobile Chain",
  nativeCurrency: { name: "WMT", symbol: "WMT", decimals: 18 },
  rpcUrls: {
    default: { http: ["https://worldmobilechain-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_API_KEY"] },
  },
});
 
const client = createPublicClient({
  chain: worldMobileChain,
  transport: http("https://worldmobilechain-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_API_KEY"),
});

Now that you've created a client connected to Alchemy, you can continue with some basics:

const blockNumber = await client.getBlockNumber();
console.log("Current block number:", blockNumber);

const balance = await client.getBalance({ address: "0xab5801a7d398351b8be11c439e05c5b3259aec9b" });
console.log("Balance (WMT):", Number(balance) / 1e18);

const block = await client.getBlock({
  blockNumber: blockNumber, // from previous example
});
console.log(block);

const tx = await client.getTransaction({ hash: "0xYOUR_TX_HASH" });
console.log(tx);

const receipt = await client.getTransactionReceipt({
  hash: "0xYOUR_TX_HASH"
});
console.log(receipt);
