Komainu acquires Singaporean digital asset custodian
Jersey-headquartered Komainu, a digital asset custodian backed by Japan’s Nomura Holdings, is in the process of acquiring Propine Holdings, a Singaporean competitor.
Subject to approval
Komainu has signed an agreement in principle with Propine to acquire the company, according to a press release published on Oct. 22 by PR Newswire on behalf of the two firms. One of the key elements in completing the deal is attaining the approval of local regulator the Monetary Authority of Singapore (MAS).
This is Komainu’s first acquisition, and according to the firm’s co-CEO Paul Frost-Smith, it will be the first of several. According to Bloomberg, Frost-Smith stated in an interview that “an absolutely key factor in building” the business is obtaining access to Propine’s Capital Market Services license, which the company was awarded in Singapore. Frost-Smith described the acquisition as "setting ourselves up for the future with a licensed platform that we can grow."
The company intends to further its efforts in terms of compliance by applying for a Major Payment Institution (MPI) license in Singapore. Komainu is motivated in developing in this manner as it has identified increasing demand from established institutions in Singapore for advisory services.

Strategic hub
The Komainu co-CEO said that the Asia-Pacific (APAC) region was central to Komainu’s heritage. With that, he added that Singapore is “an important strategic hub for Komainu in Asia and Propine will enhance our capabilities in meeting the significant client demand we are experiencing, including for Komainu Connect, our collateral management service, which is already extensively utilised by our investor clients in Hong Kong, Singapore, Malaysia, Thailand and Australia.”
Back in August, global crypto exchange platform Bitfinex signed a memorandum of understanding (MOU) with Komainu Connect, with a view towards enhancing trading security. In July Komainu was added by crypto infrastructure firm Fireblocks to its Global Custodian Partner Program.
The Japanese market has been one that Komainu has been focusing on. Frost-Smith asserted that it will serve as a major hub for the company, given that it is home to its primary backer, Nomura.
In November 2023, the company partnered with Crypto Garage, a regulated Japanese crypto-asset financial services firm. The collaboration extended Komainu’s dealings with the firm, given that it had invested in Crypto Garage’s parent company, Digital Garage, previously. At the time, the companies claimed that the partnership would allow them both to leverage their collective expertise.
Komainu has also been following a regulatory-compliant path in other markets. In the UK, where it’s stationed, it received permission from the Financial Conduct Authority (FCA) to operate as a crypto custodian in October 2023. In August of the same year, it was awarded an operating license by the Virtual Asset Regulatory Authority (VARA) in Dubai.
Alongside Nomura, the company was also established with the backing of digital asset security firm Ledger and digital asset investment manager CoinShares. Earlier this year, Komainu was approved by Nasdaq to be a core custodian relative to its suite of crypto indices.
