Quick Start

In this example we will send 1 AE coin from one account to another

1. Specify imports

For the following snippets in the guide you need to specify multiple imports.

const {
} = require('@aeternity/aepp-sdk')

2. Create a Keypair for sender

const keypair = generateKeyPair()
console.log(`Secret key: ${keypair.secretKey}`)
console.log(`Public key: ${keypair.publicKey}`)

3. Get some AE using the Faucet

To receive some AE you can use the Faucet. Just paste sender's publicKey, hit Top UP and you'll immediately get some test coins.

4. Interact with the æternity blockchain

This example shows:

  • how to create an instance of the SDK using the Aesdk class
  • how to spend (send) 1 AE from the account the SDK instance was initialized with to some other AE address
const NODE_URL = ''
const COMPILER_URL = '' // required for contract interactions
const senderAccount = new MemoryAccount({
  // replace <SENDER_SECRET> and <SENDER_PUBLIC_KEY> with the generated keypair from step 2
  keypair: { secretKey: '<SENDER_SECRET>', publicKey: '<SENDER_PUBLIC_KEY>' }

(async function () {
  const node = new Node(NODE_URL)
  const aeSdk = new AeSdk({
    compilerUrl: COMPILER_URL,
    nodes: [{ name: 'testnet', instance: node }],
  // Add sender account to the aeSdk state
  await aeSdk.addAccount(senderAccount, { select: true })

  // spend one AE
  await aeSdk.spend(1, '<RECIPIENT_PUBLIC_KEY>', {
    // replace <RECIPIENT_PUBLIC_KEY>, Ideally you use public key from Superhero Wallet you have created before
    denomination: AE_AMOUNT_FORMATS.AE


  • You may remove code from Step 2 as this serves only for one-time creation
  • By default the spend function expects the amount to be spent in aettos (the smallest possible unit)
  • Following the example snippet you would specify AE as denomination
  • See Testnet Explorer and track your transactions
