My First Transaction

In this section, we'll make our first transaction on the Mina network. After installing the software, we'll need to create a new account before we can send or receive mina. Let's first start up the node so that we can start issuing commands.

Get the network information

Because only 200 participants can join testnet 3.2b, you'll first need to get the peer addresses of the seed nodes. The 200 participants have already been selected, but you can sign up for the waitlist here in case a spot opens up.

Once you're in, you'll receive an email close to release 3.2b launch date with the seed node addresses and updated commands. We can start by storing the seed addresses as environment variables to help with the next steps:

export SEED1='<seed-address-1>'
export SEED2='<seed-address-2>'

Start up a node


You can find the current status of the network and related services here: status.minaprotocol.com

Run the following command to start up a Mina node instance and connect to the live network:

mina daemon -peer $SEED1

The -peer arguments specified above refer to the seed peer address - this is the initial peer we will connect to on the network. Since Mina is a peer-to-peer protocol, there is no single centralized server we rely on.

By default, the node connects to the network using the default external-port of 8302. This can be changed using the -external-port flag.


The daemon process needs to be running whenever you issue commands from mina client, so make sure you don't kill it by accident.

See here for common issues when first running a node.

Checking connectivity

Now that we've started up a node and are running the Mina daemon, open up another shell and run the following command:

mina client status


It may take up to a minute before mina client status connects to the daemon when first starting up. So if you see Error: daemon not running. See mina daemon, just a wait a bit and try again.

If you are using the Sandbox Node, due to a quirk in the way we communicate for the mina client status command, you will need to run mina client status inside the container itself:

docker exec -it mina bash

Most likely we will see a response that include the fields below:

Peers:                                         Total: 4 (...)
Sync Status:                                   Bootstrap

If you see Sync Status: Bootstrap, this means that the Mina node is bootstrapping and needs to sync with the rest of the network. You may need to be patient here as this step might take some time for the node to get all the data it needs. When sync status reaches Synced and the node is connected to 1 or more peers, we will have successfully connected to the network. We will also see a corresponding daemon log once we've synced: [Info] Mina daemon is now synced.

If you the Bootstrap state persists for more than an hour, there may be an issue with your port configuration.

Create a new account

Once our node is synced, we'll create a public/private key-pair so that we can sign transactions and generate an address to receive payments. For security reasons, we'll want to put the keys under a directory that is harder for attackers to access.

Run the following command to create a new account/keypair:

mina accounts create

See mina accounts -help to learn more about how to use the command.


The public key can be shared freely with anyone, but be very careful with your private key file. Never share this private key with anyone, as it is the equivalent of a password for your funds.

The response from this command will look like this:

😄 Added new account!
Public key: ZsMSUrGkF2TaBv9z2j6jco5JjL4MnywfAQtsHMuswj2zWnTUsArfEStetwuu63Um6jC


If you are one of the selected Testnet 3.2b participants that has been delegated stake, please complete the challenges using the account that you had previously created. You do not need to create a new account! (If you create a new account and use it to complete the challenges, we will not be able to track your points for your activities.)

Since the public key is quite long and difficult to remember, let's save it as an environment variable:


Now we can access this everywhere as $MINA_PUBLIC_KEY -- see if it saved properly by trying echo $MINA_PUBLIC_KEY.

Note that these environment variables will only be saved for the current shell session, so if you want to save them for future use, you can add them to ~/.profile or ~/.bash_profile.


If you are running the node on a cloud virtual machine, make sure to export and save the key file. You can export the key with:

mina accounts export -public-key <PUBLIC-KEY> -privkey-path <EXPORT-PATH>

Then save it to your local machine, maybe using scp:


Later, when starting up a new VM, you can upload the key and then import it:

mina accounts import -privkey-path <PRIVATE-KEY-FILE>

If you ever forget what keypairs you've already created, you can see them all with:

mina accounts list

Request mina


If the faucet is currently under maintenance, please request mina in the #faucet channel, and a core team member or community member will send you some tokens shortly.

Faucet Status:

In order to send our first transaction, we'll first need to get some mina to play with. Head over to the Mina Discord server and join the #faucet channel. Once there, ask Tiny the dog for some mina (you'll receive 10 mina). Here's an example:

$request <YOUR-PUBLIC-KEY>

Check account balance

It may take a few minutes for your funds to appear. We can check the balance of all our accounts using this command:

mina accounts list

You might see Balance: 0 mina for your account. Depending on the traffic in the network, it may take a few blocks before your transaction goes through.

Hint: You can run mina client status to see the current block height updating.

Make a payment

Finally we get to the good stuff, sending our first transaction! Before you send a payment, you'll need to unlock your account:

mina accounts unlock -public-key $MINA_PUBLIC_KEY

For testing purposes, there's already an echo service set up that will immediately refund your payment minus the transaction fees. You can use the following public key for the echo bot.



Currently, there is a known issue with the echo service that prevents it from properly echoing back your payment! Don't worry, we'll still give you Testnet Points* for completing the challenge.

Echo Status:

Let's send some of our newly received mina to this service to see what a payment looks like:

mina client send-payment \
  -amount 0.5 \
  -receiver B62qk5jqp4nYPwDDdd9XJAV8bYQ5cSzaZ9Me7ccaMdSSJpqKasDqMx9 \
  -fee 0.1 \
  -sender $MINA_PUBLIC_KEY

If you're wondering what we passed in to the commands above:

  • For amount, we're sending a test value of 0.5 mina
  • The receiver is the public key of the echo service
  • For fee, let's use 0.1 mina
  • The sender is the full public key, eg. 4vsRCVQq9Ai...

If this command is formatted properly, we should get a response that looks like the following:

Dispatched payment with ID 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
Receipt chain hash is now A3gpLyBJGvcpMXny2DsHjvE5GaNFn2bbpLLQqTCHuY3Nd7sqy8vDbM6qHTwHt8tcfqqBkd36LuV4CC6hVH6YsmRqRp4Lzx77WnN9gnRX7ceeXdCQUVB7B2uMo3oCYxfdpU5Q2f2KzJQ46

You may not see the Receipt chain hash on the first transaction from the account, but in following transactions, this will show you the head of the receipt chain hash list.

Once you feel comfortable with the basics of creating an address, and sending & receiving mina, we can move on to the truly unique parts of the Mina network - participating in consensus and helping compress the blockchain.
