TUTORIAL: How to Get Testnet Funds?

Tutorial Overview

In this tutorial we'll briefly explain æternity testnets – what they are, what they're used for, and how to get AE tokens from a faucet for testnets.


æternity test networks

Testnets are copies of the æternity blockchain almost identical to the live network except the fact that their AE tokens are worthless.

The æternity SDK team currently runs three testnets - sdk-testnet, sdk-edgenet and uat-testnet. Testnet is the latest stable release, and Edgenet is the next. The æternity core team runs another network, uat-testnet. It’s for internal testing and is not guaranteed to work with the SDKs. But it’s the one which has the very latest features and may be useful for you if you are an enthusiast who runs their own nodes.

In the previous tutorial we've installed aecli. So we can use aecli chain to interact with the blockchain. You can see additional information for the command here:

  -u --url [hostname]         Node to connect to (default: "")
  --internalUrl [internal]    Node to connect to(internal) (default: "")
  --networkId [networkId]     Network id (default: ae_mainnet)
  -L --limit [playlimit]      Limit for play command (default: 10)
  -P --height [playToHeight]  Play to selected height
  -f --force                  Ignore epoch version compatibility check
  --json                      Print result in json format
  -h, --help                  output usage information

  top                         Get top of Chain
  status                      Get Epoch version
  mempool                     Get mempool of Chain
  play                        Real-time block monitoring


Audience – people using released versions of our SDKs. Most software developers should use this one.

Let's check the Epoch version of sdk-testnet:

aecli chain status -u

expected output at the time of writing:

Epoch node version____________  0.25.0


Audience – people developing the SDKs, developers who need the latest features from the develop branch on github. This network is used primarily for development and can be reset without notification.

Epoch version checking:

aecli chain status -u
Epoch node version____________  1.0.0


Audience – core developers, miners, people who want to track the bleeding edge. You may not be able to connect to this using our SDKs because it’s a version later than the ones they support.

Before funding

We are going to use the secure wallet created in the previous tutorial - my-ae-wallet. Getting wallet balance:

aecli account balance <wallet_path>
  -u, --url [hostname]                               Node to connect to (default: "")
  -U, --internalUrl [internal]                       Node to connect to(internal) (default: "")
  --native                                           Build transaction natively
  --networkId [networkId]                            Network id (default: ae_mainnet)
  -P, --password [password]                          Wallet Password
  -n, --nonce [nonce]                                Override the nonce that the transaction is going to be sent with
  -f --force                                         Ignore epoch version compatibility check
  --json                                             Print result in json format
  -h, --help                                         output usage information

When checking the balance of an empty wallet, the expected output should be:

aecli account balance ./my-ae-wallet -u
prompt: Enter your password:  *****

API ERROR: Account not found

The account is not found, because the wallet actually has 0 funds and the balance is equal to 0.

Running the above command, but with -u will result in the same error.

Let's change that!

Getting tokens

There are two ways of getting tokens. The faucets operated by the SDK team will give you tokens for no effort at all. Alternatively, you can mine your own. The SDK team does not provide tokens for the uat-testnet via a faucet.


  • sdk-testnet -
  • sdk-edgenet -

In the next steps we're going to show you how to get tokens from the faucet for sdk-edgenet. The same proces could be followed for the sdk-testnet.

Initial dialog

The faucet form accepts just one parameter - wallet address. Let's bring to mind how to get it:

aecli account address my-ae-wallet

The CLI will prompt you to type in your password and will give you the following output:

Your address is: ak_2EdPu7gJTMZSdFntHK5864CnsRykW1GUwLGC2KeC8tjNnFBjBx

We are placing a request and just few seconds later, our account is topped up:

Added 250000000000000000000 AET!

Current Balance: 250000000000000000000

Transaction: [th_24L8sJY3d2Gqqd6CTnhmCKU6Ys8AyQ7HCE8q7qouDyypzoJ3aB](

Account: ak_2EdPu7gJTMZSdFntHK5864CnsRykW1GUwLGC2KeC8tjNnFBjBx

Finally, let's check the balance of wallet on sdk-edgenet:

aecli account balance ./my-ae-wallet -u

and we have it:

Your balance is: 250000000000000000000


If you want to use your node to mine, please read the following documentation: Beneficiary Account and Miner Configuration


Testnets are an incredibly useful tool in æpps development. They make the process of testing the æternity software much easier by providing safety layers on which to experiment before pushing something to the live network.
