Klaytn and SORAMITSU successfully conclude public testing of open-source DEX


  • Klaytn community played active role in public testing, with 52 bugs and 73 new feature requests raised and resolved
  • Comprehensive changelog detailing full scope of updates published in the spirit of transparency
  • Open-source DEX available as public good for any project in Klaytn ecosystem to repurpose 

As with any software or infrastructure prior to launch, our SORAMITSU-built DEX infrastructure underwent thorough public testing to ensure its ability to perform seamlessly under the rigors of diverse usage scenarios, as well as to provide opportunities for the Klaytn community to provide valuable feedback. 

After a month of public testing, we’re glad to share that our full-stack, open-source DEX infrastructure is now improved and ready for public use! Completed in November 2022, our DEX allows users to swap tokens, stake and provide liquidity, mint tokens, participate in decentralized governance, and monitor the exchange’s activities through dashboards, with all these functionalities being open-source and decentralized. 

Our community played an active role in the testnet, raising 154 issues on Github. These issues included 52 bugs and 73 new feature requests, addressed and resolved in releases on December 19th and January 11th. The feedback received from our community was not only helpful in identifying issues but also encouraging, for which we are extremely grateful.

In the spirit of transparency, the SORAMITSU team compiled a comprehensive changelog of all updates and made it accessible to the entire Klaytn community. 

The completion of this DEX backbone represents a public benefit for all participants in the Klaytn ecosystem. Neither Klaytn nor SORAMITSU will operate the DEX: instead it will be fully open-source decentralized and open to anyone to run on their own. This promotes interoperability and composability, while expanding the possibilities within Klaytn’s DeFi ecosystem. Furthermore, as the SORAMITSU-built DEX is open-source, projects have the flexibility to customize new features and visualizations based on their users’ specific needs.

Dr Sangmin Seo, Representative Director, Klaytn Foundation said, “The successful testnet completion for our open-source DEX, built by our trusted partner SORAMITSU, is a testament to the strength and active participation of our community. Their valuable feedback, including 154 issues raised and resolved on Github, has played a crucial role in shaping and improving the functionality of this open-source and decentralized infrastructure. We are grateful for their engagement and look forward to continued cooperation to grow the Klaytn ecosystem.”

Andrew Wong, Chief Operating Officer, SORAMITSU Group, said, “The Klaytn ecosystem is known to be one of the world’s most advanced blockchains; pushing the boundaries in the metaverse, gaming and creator economy. The conclusion of the DEX public testnet release marks a significant accomplishment for the SORAMITSU and Klaytn teams. My hope is that this can empower a new wave of potential operators and companies to start their Web3 journey on Klaytn. We look forward to building future collaborations within the Klaytn ecosystem.”
