How to become a liquidity provider on DogeDEX network?
An explanation on how to provide liquidity on DogeDEX network.
Can I setup liquidity on DogeDEX?
Yes, there are two ways that you can add liquidity to the DEX. One way is using the mobile or desktop application and creating orders with a price and volume of your choosing. The second way is creating a dedicated liquidity provider node (LP).
We are working on a simpler way to setup the LP nodes from a desktop. Currently, you need to have experience with command-line interfaces to set up an LP node.
LPs on DogeDEX are not like LPs on Uniswap. In order to make profits, LP nodes needs to arbitrage between exchanges. They can buy low and sell higher on the DEX network or vice versa. There are benefits to this architecture. There's no impermanent loss on DogeDEX and more secure contracts. On a Uniswap automated market maker model, you're exposed to impermanent loss as a liquidity provider as well as security risks with the contract.
How To Become a Liquidity Provider on AtomicDEX
The following tutorial introduces the reader to a simple method to become a liquidity provider on the main network of the AtomicDEX software.
#Virtual Private Server (Recommended)
We recommend that the user have a Virtual Private Server (VPS) (opens new window)with at least the following specifications.
- 2 vCPU
- 4GB RAM
- OS: Ubuntu 18.04 (Preferably a clean installation)
#Home-Based Connection
If the user prefers to use computer hardware at home, instead of a VPS, we recommend that the user have a very strong Internet connection. We also recommend that the user have a competitive hardware setup running on Ubuntu 18.04.
- Internet speed - at least 1 MBPS
- RAM - at least 4 GB
- Processor - at least i5 or equivalent

#Create a Secure Seed Phrase
The user must create a seed phrase that will serve as a type of password for accessing all coins in the user's digital wallet.
Various tools are available in the cryptocurrency community to create a secure seed phrase. One available method is to use the automated procedure that is included in the Verus Agama Wallet (opens new window).
Backup these 24 words carefully. They provide access to the coins that are stored in the addresses created by the MarketMaker.
To learn more about creating secure phrases, read this linked content on the Bitcoin wiki.(opens new window)​
#Edit the start.sh File
Danger!
We are about to place the seed phrase in the user's start.sh file. This step is crucial for cryptocurrency security. Failure to properly execute this step can (and likely will) lead to a loss of all your funds.
Open the
start.sh file in the current directory using the nano software.1
nano start.sh
Copied!
Replace the value
REPLACE_TRADING_WALLET_PASSPHRASE in the file with the seed phrase.#Create an RPC Control User Password
Keep the nano software and
start.sh file open.Separately, create an additional password for Remote Procedure Call (RPC) access.
This should be a simple password that is sufficiently random, has at least eight digits, and is based on numbers and letters.
#Place the User Password into the start.sh File
Replace the text
"RPC_CONTROL_USERPASSWORD" with your RPC user password.#Example
Show Example
Hit
Ctrl + X to save and exit.Observe the bottom of the terminal for any prompts. Hit
y when asked to save. When the file name is shown, hit Enter if the name matches start.sh.#Edit the userpass File
Replace the text
RPC_CONTROL_USERPASSWORD with the same password used in the start.sh file.Show ExampleWe now have basic scripts to use the MarketMaker as a liquidity provider.
#Step 2: Start the MarketMaker
#Command
1
./start.sh
Copied!
Show Sample Output
Note
Starting the MarketMaker 2.0 software in the above manner causes the passphrase to be visible to other programs such as
htop.To avoid this issue, there is an alternate method that uses a json file to replace the command line parameters
To use it:
1
cp MM2_sample.json MM2.json
2
nano MM2.json
Copied!
Edit the values of the keys
"rpc_password" and "passphrase" with the same values used in the start.sh file. Save and close the file.To start the MarketMaker:
1
stdbuf -oL nohup ./mm2
Copied!
#Step 3: Connect to the Coin Networks (KMD & LTC)
Open a new terminal and navigate to the directory:
~/atomicDEX-API/target/debug1
cd ~/atomicDEX-API/target/debug
Copied!
#Connect to the KMD network
#Command
1
./KMDconnect.sh
Copied!
#Response
1
{"address":"RG1yR8UGqyHmRBcrwAakUEi8u1AC5jNABY","balance":"0","coin":"KMD","result":"success"}
Copied!
Take note of the address.
TIP
We recommend here that you make sure that the public address above matches the address generated by the same passphrase, when entered into the AtomicDEX wallet or the Verus Agama wallet.Show Response

#Connecting to a Network Other Than KMD or LTC
To connect to a coin network other than KMD or LTC, first make sure that the coin's details are present in the
coins file you downloaded. Also make sure that the file has the property "mm2": 1.Next, create a new file named "COINNAMEconnect.sh" and add the following contents; replace the characters
< and > and all text between them with values from your coins file. (For example: <text where 7771 should be inserted> becomes 7771.)1
#!/bin/bash
2
source userpass
3
curl --url "http://127.0.0.1:7783" --data "{\"userpass\":\"$userpass\",\"method\":\"electrum\",\"coin\":\"<COIN TICKER>\",\"servers\":[{\"url\":\"<url of electrum server 1>\"},{\"url\":\"<url of electrum server 2>\"}]}"
Copied!
Make the file executable
1
cd ~/atomicDEX-API/target/debug
2
chmod +x COINNAMEconnect.sh
Copied!
Execute the command
./COINNAMEconnect.sh to instruct your Market Maker 2 instance to connect to the coin's electrum server.#Step 0: Query the Current Orderbooks
Display the KMD/LTC Orderbook.

To achieve this, we first fund the KMD address created by the MarketMaker.
Use the following command to find the address and check the balance.
