# Set up environment

These are the steps needed to build Haveno and test it on our test network or locally.

## Install dependencies

On Ubuntu: `sudo apt install make wget git git-lfs openjdk-11-jdk`. The Monero binaries will be downloaded and verified automatically in the next step.

## Build Haveno

1. Download this repository: `git clone https://github.com/haveno-dex/haveno.git`
2. Navigate to the root of the repository (`cd haveno`) and build the repository: run `make` in the terminal and wait until the process is completed (this will also download and verify the Monero binaries).

## Join the public test network

If you want to try Haveno in a live setup, launch a Haveno instance that will connect to other peers on our public test environment, which runs on Monero's stagenet. You'll be able to make test trades with other users and have a preview of Haveno's trade protocol in action. Note that development is very much ongoing. Things are slow and might break.

Steps:

1. Run `make user1-desktop-stagenet` to start the application.
2. Click on the "Funds" tab in the top menu and copy the generated XMR address.
3. Go to the [stagenet faucet](https://community.rino.io/faucet/stagenet/) and paste the address above in the "Get XMR" field. Submit and see the stagenet coins being sent to your Haveno instance.
4. While you wait the 10 confirmations (20 minutes) needed for your funds to be spendable, create a fiat account by clicking on "Account" in the top menu, select the "National currency accounts" tab, then add a new account. For simplicity, we suggest to test using a Revolut account with a random ID.
5. Now pick up an existing offer or open a new one. Fund your trade and wait 10 blocks for your deposit to be unlocked.
6. Now if you are taking a trade you'll be asked to confirm you have sent the payment outside Haveno. Confirm in the app and wait for the confirmation of received payment from the other trader.
7. Once the other trader confirms, deposits are sent back to the owners and the trade is complete.

If you are a developer who wants to test Haveno in a more controlled way, follow the next steps to build a local test environment.

# Run a local test network

## Run a local XMR testnet

1. In a new terminal window run `make monerod-local1`
1. In a new terminal window run `make monerod-local2`
3. Now mine the first 130 blocks to a random address before using, so wallets only use the latest output type. Run in one of the terminal windows opened above:

`start_mining 9tsUiG9bwcU7oTbAdBwBk2PzxFtysge5qcEsHEpetmEKgerHQa1fDqH7a4FiquZmms7yM22jdifVAD7jAb2e63GSJMuhY75 1`

## Deploy

If you are a *screen* user, simply run `make deploy`. This command will open all needed Haveno instances (seednode, user1, user2, arbitrator) using *screen*. If this is the first time launching the arbitrator desktop application, register the arbitrator as explained in step 3 below.

If you don't use *screen*, open 4 terminal windows and run in each one of them:

  1. `make seednode-local`
  2. `make user1-desktop-local` or if you want to run user1 as a daemon: `make user1-daemon-local`
  3. `make user2-desktop-local` or if you want to run user2 as a daemon: `make user2-daemon-local`

If this is the first time launching the arbitrator desktop application, register the arbitrator after the interface opens. Go to the *Account* tab and press `cmd+r`. Confirm the registration of the arbitrator.

## Fund your wallets

When running user1 and user2, you'll see a Monero address prompted in the terminal. Send test XMR to the addresses of both user1 and user2 to be able to initiate a trade.

You can fund the two wallets by mining some test XMR coins to those addresses. To do so, open a terminal where you ran monerod and run: `start_mining ADDRESS 1`.

monerod will start mining local testnet coins on your device using one thread. Replace `ADDRESS` with the address of user1 first, and then user2's. Run `stop_mining` to stop mining.

## Start testing

You are all set. Now that everything is running and your wallets are funded, you can create test trades between user1 and user2. Remember to mine a few blocks after opening and accepting the test trade so the transaction will be confirmed.
