SORAMITSU and Klaytn Collaboration: Testnet for Open Source Decentralized Exchange Infrastructure Completed

Klaytn’s trusted technology partner SORAMITSU has just concluded a successful testnet for the open-source DEX infrastructure built for the community.

The testnet for the SORAMITSU-built DEX infrastructure for the Klaytn network was successfully completed on the 20th of January 2023. The infrastructure, which was completed in November 2022, 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.

The Klaytn community was actively involved in the testnet, with 154 issues raised and resolved on Github. Out of these, 52 were bugs, and 73 were new feature requests, which were addressed in a release on the 19th of December and the 11th of January. Additionally, some of the issues raised were in fact encouraging feedback from the Klaytn community, of which we are wholeheartedly grateful.

The scope of the updates was compiled in a changelog that was then made available to the Klaytn community.
Completing this DEX backbone is an accomplishment that cements SORAMITSU's status as a premier tech provider to the Klaytn network, and through the use of open-source and decentralized technologies, the network and its users benefit from robust, safe, and future-proof software, as well as a trustworthy liquidity hub for the Klaytn economy.

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.

Klaytn is a huge ecosystem with a big community. This advantage allowed us to successfully test the DEX with huge community interest. I would like to separately acknowledge the support granted to us by Klaytn Ecosystem members, the Klaytn team, and testnet participants. I believe that this kind of interaction will allow us to build new web3 technological solutions based on the Klaytn blockchain in the future.

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.
