Shape is a chain for creators built on top of Ethereum. It's an open space where everyone is free to create, from fine art to experimental projects, fostering a unique cultural ecosystem. Shape offers creators the opportunity to claim back 80% of sequencer fees users spend interacting with their contracts, making it an attractive platform for innovative content creation.

The Shape API allows interaction with the Shape 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.

Send Your First Request on Alchemy

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

npm install --save viem

Create Client Connected to Alchemy

import { createPublicClient, http } from "viem"; 
import { shape } from "viem/chains";
 
const client = createPublicClient({
  chain: shape,
  transport: http("https://shape-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 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 (ETH):", 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 Transaction Receipt

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