Propine
Singapore-licensed digital asset custody provider, now Komainu's Asia arm after 2024 buyout.
On the record
Checkpoint: Komainu CORE collateral-as-a-service launch and any Asia mandate wins reported
The call
Propine's license bought Komainu a Singapore foothold, but the surviving business now has to out-run banks and crypto custodians with far deeper pockets.
Propine holds a Singapore banking license that lets it safely store cryptocurrency for clients, which is hard to get but not impossible for deep-pocketed rivals like BitGo, Coinbase, or even traditional banks like BNY Mellon to obtain. Before Komainu bought it in October 2024, Propine was tiny and losing money, meaning the license was the real prize, not an existing customer base or proven business model. Everything hinges on whether Komainu can win over Asia's big institutions faster than better-funded competitors, and whether major custody breaches or regulatory changes shake up the whole sector.
Why
01
AI pressure: None apparent. Custody is a licensing and security business, not something AI models replace directly. Could AI do the core job? Unlikely.
02
Bigger players: BitGo, Fireblocks, Anchorage, Coinbase Custody, Sygnum, BNY Mellon, State Street. Bigger, better-funded custodians with their own licenses are expanding into Asia and can out-market Komainu's small team. Could a giant copy it? Yes, easily.
03
What protects it. The MAS custody license took years to get and keeps casual entrants out, even if it does not stop funded rivals.
What would change this call
Whether the Propine brand is formally retired and folded into Komainu within 12 months. Shows whether integration is proceeding or stalling post-acquisition.
Whether BitGo, Coinbase Custody, Fireblocks, or Sygnum announce marquee Asia ETF or tokenization mandates. Shows rivals capturing Asia institutional custody business Komainu is targeting.
Whether Komainu raises a Series C or discloses Asia AUC/revenue figures publicly. Shows whether Komainu is converting Asia distribution and scaling versus larger custodians.

Key numbers
- Pre-acquisition revenue was just $189,395
- EBITDA loss of $4.37 million on that tiny revenue
- Komainu closed a $75 million Series B in Bitcoin
Named risks
- Competing for same institutional mandates as larger, better-capitalized custodians like BitGo and Fireblocks.
- Standalone Propine was loss-making pre-acquisition, suggesting weak commercial traction before Komainu takeover.
- MAS licensing rules could tighten, raising compliance costs across Singapore digital asset custody sector.
- Sector-wide shock such as major exchange collapse or custody breach could hit institutional trust broadly.
- Backer Nomura running its own tokenized collateral pilot with Mizuho and JSCC could reduce reliance on Komainu custody.

Questions people ask
- Is Propine still an independent company or was it acquired?
- Propine was acquired by Komainu in a deal agreed October 21, 2024, subject to MAS approval. It now operates as Komainu's Singapore and Asia subsidiary rather than as a standalone company, per Businesswire's October 21, 2024 announcement.
- Is Propine profitable?
- Propine was reported as loss-making before its October 2024 acquisition by Komainu. No standalone post-acquisition revenue or profit figures for the Propine unit have been publicly disclosed as of mid-2026.
- Who owns Propine now?
- Propine is owned by Komainu Holdings Limited, which acquired it in October 2024. Komainu itself is backed by Nomura, Ledger, CoinShares, Laser Digital, and Blockstream, and closed a self-reported 75 million dollar Series B in May 2025, per Komainu's own August 20, 2025 statement.
- Could AI replace Propine or Komainu's custody service?
- No. Digital asset custody requires a licensed, insured, fiduciary structure such as Propine's MAS Capital Markets Services Licence, which AI cannot substitute for. AI can automate back-office reporting and reconciliation, as seen in Komainu's Portal dashboard launched April 22, 2026, but not legal custody itself.
- Who are Propine's and Komainu's biggest competitors?
- Key rivals include BitGo, Fireblocks, Anchorage Digital, Coinbase Custody, Copper, and Sygnum, several of which are already MAS-licensed or MAS-adjacent in Singapore, per BitGo's own June 19, 2025 Singapore entity filing. Traditional custodian banks are also entering the space.
- What happened to the Propine brand after the Komainu acquisition?
- No formal Propine brand retirement has been publicly announced, but coverage since the October 21, 2024 acquisition consistently describes the business as operating under Komainu, with founder CEO Tuhina Singh remaining in place through the transition.
