Sonic is an EVM-compatible, high-performance, scalable, and secure layer-1 blockchain. With over 10,000 TPS, one-second confirmation times, and low-cost transactions, it provides a robust platform for decentralized applications (dApps) and Ethereum-based deployments.

The Sonic API lets you interact with the Sonic network through a set of JSON-RPC methods. If you've worked with Ethereum's JSON-RPC APIs, the design will feel familiar.

Send your first request on Alchemy

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

npm install --save viem

yarn add viem

Create a client connected to Alchemy

import { createPublicClient, http } from "viem"; 
import { sonic } from "viem/chains";
 
const client = createPublicClient({
  chain: sonic,
  transport: http("https://sonic-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:

Get the latest block number

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

Get an address balance

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

Read block data

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

Fetch a transaction by hash

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

Fetch a transaction receipt

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