Klaytn and SORAMITSU Announce Completion of Open-Source DEX


  • SORAMITSU has developed an open-source decentralized exchange (DEX) infrastructure for the Klaytn blockchain.
  • The open-source DEX will initially have various features, from fungible token swapping and token-based governance to staking and liquidity provision and token minting.
  • The DEX will be available for users to test from 29 November 2022.

Decentralized exchanges (DEXes) serve as a key pillar of a blockchain ecosystem, providing trustless access to liquidity and helping networks gain growth and traction. 

With this in mind, a collaboration with SORAMITSU to build the backbone architecture and design for an open-source DEX on the Klaytn blockchain was announced in March.

After seven months of close cooperation, it is our pleasure to announce that the DEX infrastructure is complete. Proposed via the Klaytn Improvement Reserve (KIR), the open-source release will advance Klaytn’s vision of allowing more users to be part of the Web3 revolution while keeping the network at the forefront of technological developments. 

The open-source DEX will initially have a range of features, from fungible token swapping and token-based governance to staking and liquidity provision as well as token minting. It will also incorporate dashboards for ease of data visualization for Klaytn network users. The DEX backbone architecture will also allow DEX operators to implement tokenomics and provide liquidity.

In the spirit of openness and transparency, the progress of the SORAMITSU-developed open-source DEX infrastructure was documented in milestones and presented to the Klaytn community through the KIR. 

Sangmin Seo, Representative Director, Klaytn Foundation, said, “We are pleased with the progress made on the open-source DEX by SORAMITSU. This significant milestone serves as a testament to the new possibilities our ecosystem has for further interoperability and decentralization within the Klaytn metaverse.”

Andrew Wong, Chief Operating Officer, SORAMITSU, said, “We couldn’t be more proud to partner with the Klaytn community to advance their ongoing globalization efforts. Our common focus on building for the long term, together with our unique combination of assets, technology, and people, will enable both SORAMITSU and Klaytn to achieve our shared vision for a decentralized tomorrow.”

The SORAMITSU-developed open-source DEX infrastructure will be available for public testing from 29 November 2022 till 20 January 2023. Access the testnet here and view the user guide and testnet tutorial video for more guidance.
