What isSNA? (Sigmachain Network Alliance)

  • Although the block chain is a catalyst to broaden the digital world, there is a limit to how innovation can be achieved by technology alone.
    The Sigmachain has grown based on the experience of developing Cyworld, the first SNS platform in Korea.
    Based on this experience, we can provide you with a complete solution utilizing the accumulated experience of online SNS business and Sigmachain’s technology.
  • Using the inhouse built mainnet technology, Sigmachain is planning to provide its mainnet services
    for SNS, entertainment, life, fashion, healthcare, sports, etc. in order to rapidly grow.
  • These mainnets operate independently and are connected to the master mainnet of the Sigmachain,
    enabling mutual verification and additional synergy effects,
    and thereby expanding the blockchain network ecosystem using blockchain technology.


We support the development and marketing of each main coin so that we can build our own ecosystem to attract various tokens.

By forming a coin trading market to activate the Sigmachain network, we act as the SNA world's key currency.

We will create a synergy environment where mainnets and DApps belonging to SNA can have win-win situation through mutual marketing cooperation.

We provide a marketplace where people can exchange, buy and sell coins and tokens of services in the Sigmachain network.
