NOTE: The filenames in each subdirectory needs to match the coin's symbol exactly, that is the unique field that things are indexed by. Also for icons, please use .png files

About this repository

This repository is the coins database which is accessed by graphical applications like BarterDEX GUI.

When submitting a pull request to add coin to BarterDEX make sure you have completed this checklist:

0. The coin must be tested with BarterDEX atomic swaps

When submitting your coin add request please post the 5 transactions URLs produced by successful swap in separate file inside swaps dir, example. This means that before submitting the further steps information to this coins database repo, you would have performed an atomic swap, and the further steps explains the expected files/values to be submitted to this database repo.

You can learn about performing an atomic swap from our documentation link https://docs.komodoplatform.com

Or you can contact the team at [email protected] to get help if required.

1. Coin info added to coins file (Required)

You need the following info in JSON format added to coins file:

# Example 1
{
  "coin": "LTC",
  "name": "litecoin",
  "fname": "Litecoin",
  "rpcport": 9332,
  "pubtype": 48,
  "p2shtype": 5,
  "wiftype": 176,
  "txfee": 100000,
  "mm2": 1
}

# Example 2
{
  "coin":"PEW",
  "name":"brofist",
  "fname": "Brofist",
  "confpath": "USERHOME/.brofistcore/brofist.conf"
  "rpcport":12454,
  "pubtype":55,
  "p2shtype":10,
  "wiftype":198,
  "txfee":10000,
  "mm1": 1
}

# Example 3
{
  "coin": "REP",
  "name": "augur",
  "fname": "Augur",
  "etomic": "0xE94327D07Fc17907b4DB788E5aDf2ed424adDff6",
  "rpcport": 80,
  "mm2": 1
}

General parameters

"mm2" add this param if coin is confirmed working with MM2 (successful swap is made).

Bitcoin Protocol specific JSON

"coin" must be coin ticker.

"name" must be coin's name, in all small letters. This is the value which is expected to be default data directory name for that coin. Example if coin's name is litecoin then it's expected data directory on Linux is ~/.litecoin/, on Mac ~/Library/Applications Support/Litecoin/, on Windows %AppData%\Litecoin. Please keep this key's value in small letters only.

"confpath" must be ONLY used in case the expected data directory name of the coin/project is different to the "name"'s value, as explained in last point. Please refer to Example 2 for better understanding. Make sure to use the exact format for confpath. You don't need to change the word USERHOME, it remains as is. Make sure you have /. after USERHOME. And then the expected coin/project's data directory path and it's expected .conf file name.

"fname" must be coin's full name.

"rpcport" must be coin's default RPC port. It is expected that it doesn't conflict with any existing coin in the coins db.

"pubtype", "p2shtype", and "wiftype" is the also very specific information about coin's parameters. This is specific to Bitcoin Protocol compatible coins only, and such information can be found in source code of the project. These parameters information can be expected in files like src/init.cpp, src/base58.h, and src/chainparamsbase.h if the project is following the bitcoin source code directory/files structure. If the parameters info is unclear then please have these confirmed by that coin/project's developers and make sure it's correct information.

"txfee" is a value of default transactions fee, which must be specified in satoshies unit. BarterDEX uses this as the default transaction fee value when makes atomic swaps transactions.

Ethereum Protocol specific JSON

Ethereum protocol specific coin/project add request are the most simplest. "coin", "name", and "fname" information is same as explained in bitcoin protocol specific json section.

"rpcport" must remain default for all ERC20 token/coins. Make sure its only specified as 80.

"etomic" must be the ERC20 token/coin's smart contract address.

2. Icon file (Required)

• The icon file is required.
• Icon must be a .png format file.
• Dimentions of icon file is 82x82 pixels.
• Icon file name MUST be in small letters.
• Icon file location is icons directory.

3. Explorer URL (Required)

• Explorer file name must be coin's ticker name matching the "coin" value as specified in coins file.
• Explorer file name must not have any file extension. It is a file without any . extension.
• Explorer file name must be all in capital letters.
• It must have a valid JSON array with at least one Explorer URL in it. It's better if there are more than one explorer URLs in this JSON array. Example: ["http://example1.com/tx/","http://example2.com/tx/"].
• The URL of Explorer must be pointing to the transactions URL. Check BTC file for an example: explorers/BTC, which has ["https://www.blocktrail.com/BTC/tx/"]. This explorers URL is used to show in graphical applications to link to the transactions like this example link. Make sure this URL ends with /.

4. Electrum Servers (Optional)

• Electrum file name must be coin's ticker name matching the "coin" value as specified in coins file.
• Electrum file name must not have any file extension. It is a file without any . extension.
