Create an Account

Before we get started with working with Stellar in code, consider going through the following examples using the Stellar Laboratory. The lab allows you create accounts, fund accounts on the Stellar test network, build transactions, run any operation, and inspect responses from Horizon via the Endpoint Explorer.

Accounts are a fundamental building block of Stellar: they hold all your balances, allow you to send and receive payments, and let you place offers to buy and sell assets. Since pretty much everything on Stellar is in some way tied to an account, the first thing you generally need to do when you start developing is create one. This beginner-level tutorial will show you how to do that.

Create a Keypair

Stellar uses public key cryptography to ensure that every transaction is secure: every Stellar account has a keypair consisting of a public key and a secret key. The public key is always safe to share — other people need it to identify your account and verify that you authorized a transaction. It's like an email address. The secret key, however, is private information that proves you own — and gives you access to — your account. It's like a password, and you should never share it with anyone.

Before creating an account, you need to generate your own keypair:

// create a completely new and unique pair of keys// see more about KeyPair objects: pair = StellarSdk.Keypair.random();pair.secret();// SAV76USXIJOBMEQXPANUOQM6F5LIOTLPDIDVRJBFFE2MDJXG24TAPUU7pair.publicKey();// GCFXHS4GXL6BVUCXBWXGTITROWLVYXQKQLF4YH5O5JT3YZXCYPAFBJZB

Create Account

A valid keypair, however, does not make an account: in order to prevent unused accounts from bloating the ledger, Stellar requires accounts to hold a minimum balance of 1 XLM before they actually exist. Until it gets a bit of funding, your keypair doesn't warrant space on the ledger.

On the public network, where live users make live transactions, your next step would be to acquire XLM, which you can do by consulting our lumen buying guide. Because this tutorial runs on the test network, you can get 10,000 test XLM from Friendbot, which is a friendly account funding tool.

To do that, send Friendbot the public key you created. It’ll create and fund a new account using that public key as the account ID.

// The SDK does not have tools for creating test accounts, so you'll have to// make your own HTTP request.// if you're trying this on Node, install the `node-fetch` library and// uncomment the next line:// const fetch = require('node-fetch');(async function main() {  try {    const response = await fetch(      `${encodeURIComponent(        pair.publicKey(),      )}`,    );    const responseJSON = await response.json();    console.log("SUCCESS! You have a new account :)\n", responseJSON);  } catch (e) {    console.error("ERROR!", e);  }})();

Now for the last step: getting the account’s details and checking its balance. Accounts can carry multiple balances — one for each type of currency they hold.

const server = new StellarSdk.Server("");// the JS SDK uses promises for most actions, such as retrieving an accountconst account = await server.loadAccount(pair.publicKey());console.log("Balances for account: " + pair.publicKey());account.balances.forEach(function (balance) {  console.log("Type:", balance.asset_type, ", Balance:", balance.balance);});

Now that you’ve got an account, you can start sending and receiving payments, or, if you're ready to hunker down, you can skip ahead and build a wallet or issue a Stellar-network asset.


In the above code samples, proper error checking is omitted for brevity. However, you should always validate your results, as there are many ways that requests can fail. You should refer to the guide on Error Handling for tips on error management strategies.
