Send/Receive Stacks on Testnet
This quickstart guide will show you how to setup a Stacks wallet using the Blockstack JavaScript CLI and use it to send/receive Stacks tokens on Testnet. This wallet is intended for developer experimentation with Testnet only, do not use this wallet to store your tokens.
Prerequisites
You will need to have npm installed.
Installation
To install the Blockstack CLI, run the following command in terminal.
npm install -g https://github.com/blockstack/cli-blockstack#feature/stacks-2.0-tx
Creating a Wallet
First, we are going to generate a new wallet for Testnet. To generate a wallet use the make_keychain command with the -t option for Testnet.
$ blockstack make_keychain -t
{
"mnemonic": "private unhappy random runway boil scissors remove harvest fatigue inherit inquiry still before mountain pet tail mad accuse second milk client rebuild salt chase",
"keyInfo": {
"privateKey": "381314da39a45f43f45ffd33b5d8767d1a38db0da71fea50ed9508e048765cf301",
"address": "ST1BG7MHW2R524WMF7X8PGG3V45ZN040EB9EW0GQJ",
"btcAddress": "n4X37UmRZYk9HawtS1w4xRtqJWhByxiz3c",
"index": 0
}
}
The mnemonic is your 24 word seed phrase which you should back up securely if you want access to this wallet again in the future. Once lost, it cannot be recovered.
The Stacks address associated with this wallet is:
ST1BG7MHW2R524WMF7X8PGG3V45ZN040EB9EW0GQJ
Note that this is a Testnet address for use with Testnet only. You will use this address to receive tokens from the Testnet faucet or other people.
The private key is what you will need to send tokens later.
Getting Tokens
To receive Testnet Stacks tokens, visit the Testnet stacks token faucet. Enter the Stacks address you generated above into the address field on the faucet page and click "Get STX".
Once the faucet transaction has been broadcasted, you will need to wait for the balance to be reflected in your account.
Checking Balance
Once you’ve requested Testnet Stacks tokens from the faucet, you can check the balance of your account using the following command.
$ blockstack balance ST1BG7MHW2R524WMF7X8PGG3V45ZN040EB9EW0GQJ -t
{
"balance": "10000",
"nonce": 0
}
By default, using the -t flag causes the CLI to connect to the neon testnet node at http://neon.blockstack.org:20443.
To specify a node to connect to, add the -H flag followed by the URL of the node "http://localhost:20443". This flag can be used with all commands in this guide.
Verify that your account has tokens before continuing to the next step to send tokens.
Take note that the nonce for the account is 0. We will be using this number in the next step.
Sending Tokens
In order to send tokens, we will need the 5 parameters below.
Recipient Address - The Stacks address of the recipient
Amount - The number of Stacks to send denoted in microstacks (1 STX = 1000000 microstacks)
Fee Rate - The transaction fee rate for this transaction. You can safely set a fee rate of 1 for Testnet.
Nonce - The nonce is a number that needs to be incremented monotonically for each transaction from the account. This ensures transactions are not duplicated. You can get the latest valid nonce for each account using the balance command.
Private Key - This is the private key corresponding to your account that was generated when you created the wallet earlier using the CLI.
Once we have the parameters, we can use the send_tokens command:
$ blockstack send_tokens ST2KMMVJAB00W5Z6XWTFPH6B13JE9RJ2DCSHYX0S7 1000 200 0 381314da39a45f43f45ffd33b5d8767d1a38db0da71fea50ed9508e048765cf301 -t
d32de0d66b4a07e0d7eeca320c37a10111c8c703315e79e17df76de6950c622c
With this command we’re sending 1000 microstacks to the Stacks address ST2KMMVJAB00W5Z6XWTFPH6B13JE9RJ2DCSHYX0S7.
We set the fee rate to 200 microstacks. If you're not sure how much your transaction will cost. You can add the -e flag to estimate the transaction fee needed to get processed by the network, without broadcasting your transaction.
The nonce is set to 0 for this transaction, since it will be the first transaction we send from this account. For subsequent transactions, you will need to increment this number by 1 each time. You can check the current nonce for the account using the balance command.
Finally, the last parameter is the private key from earlier. 381314da39a45f43f45ffd33b5d8767d1a38db0da71fea50ed9508e048765cf301
Once again, we’re using the -t option to indicate that this is a Testnet transaction, so it should be broadcasted to Testnet.
If valid, your transaction will now be broadcasted to the network and you will see the transaction ID displayed on the screen.
To view the raw transaction without broadcasting, add the -x flag to your command.
