Colorcore is an open source colored coin wallet compatible the Open Assets protocol and Coinprism.

Colored Coins



  • Issue you own coins

Anybody can issue their own coins. It only takes a single Bitcoin transaction. The only fee you have to pay is the Bitcoin transaction fee (which can be zero), which makes Colorcore much more efficient than alternatives like XCP (about $20 to issue an asset). Also, you don't need to buy any intermediary coin (like XCP) since colored coins work directly on top of Bitcoin.

  • Send and receive assets

Use your address to receive assets from other people. You can also send assets, again for the price of a standard Bitcoin transaction.

  • Manage crowdfunding campaigns

Finally a way to manage a truly decentralized crowdfuding campaign. You don't have to trust a complex and limited exchange protocol, the "distribute" feature creates standard Bitcoin transactions. There is no magic behind it.

Every asset created or exchanged using Colorcore are visible on the block explorer, and can be sent to a Coinprism web-wallet.

Installation and dependencies

Colorcore does not connect to any external service. All it needs is access to the Bitcoin blockchain, via Bitcoin Core. Therefore in order to run Colorcore, you need Bitcoin Core running with RPC enabled and the -txindex=1 -server=1 flags.

Follow these instructions to install Colorcore:

  • Windows users: make sure you have Python 3 and pip installed on your machine
  • Run the following commands:

git clone cd colorcore pip install --upgrade -r requirements.txt

  • Edit the config.ini file with the username, password and port for your local Bitcoin Core instance (rpcurl setting).

You are now ready to run Colorcore.


  • Coinprism launches Colorcore, an open source colored coin wallet compatible with open assets and Coinprism: September 2nd 2014 [1]
