DMM Crypto shutters Seamoon Protocol
DMM Crypto, the crypto exchange, blockchain gaming and NFT arm of Japanese e-commerce and internet firm DMM, has taken the decision to shut down the Seamoon Protocol.
Economic zone concept project
Taking to X on Nov. 15, the project outlined that it has decided to cancel the economic zone concept project, Seamoon Protocol. The project added:
”We would like to express our deepest gratitude to the business operators who have provided us with so much support thus far, as well as to all those who have placed their hopes in this project and shown us their kind support, and we would like to offer our heartfelt apologies.”
The move suggests a sudden change in the fortunes of the project. As recently as last August, DMM Group had announced a collaboration with Progmat, a distributed ledger technology (DLT) platform for tokenization and stablecoins, with a view towards looking into the issuance of a stablecoin. The stablecoin was intended to act as a reserve currency, providing backing for Seamoon Protocol’s treasury pool while also acting as a price stabilization mechanism.
At the time, DMM Crypto CEO Nagato Kasaki had said that the Seamoon Protocol had been launched in order to create a space “where a global community could experience DMM’s cultural universe and co-create new experiences together.”
Notwithstanding that goal, no new services are planned to replace the Seamoon Protocol.

Launched in 2023, Seamoon Protocol ran on the DM2 Verse, a layer-2 network associated with the Oasys blockchain. DM2 Verse was designed to act as a community hub for the Seamoon Protocol, hosting NFT drops, games, tournaments and collaborations. Activity on Seamoon was powered by its own native SMP token.
Changing business environment
Norbert Gehrke, a commentator on the Japanese fintech sector, outlined in a Medium blog post that Seamoon was abruptly terminated “due to recent rapid changes in the business environment that have created challenges for the project’s sustainability.”
The company didn’t provide detail on the nature of the challenges encountered which impacted on the sustainability of the project.
With the shutdown, issuance of the SMP token will be discontinued. Furthermore, new service applications for the Seamoon Protocol platform have been suspended. It’s unclear what will now happen with existing services which have been built on the platform. The company has suggested that this matter is under discussion.
One exception is the Kanpani Girls RE:BLOOM project, a Web3 game that was the first of five games that had been envisaged for the protocol. The company has confirmed that this project will be terminated.
In-game notices will be provided at a later stage to provide users with advice regarding refunds and compensation for game items. The game will be wound down by the end of January.
Once decisions have been made relative to other services and projects, the company will make announcements on the social media channels of those affected services.
DMM Crypto received investment from Neoclassic Capital last month, with a view towards pursuing a global expansion strategy.
