Wiki route

Alterna Trust is a standalone trust-company route under trust-banks INDEX and is promoted from the Japan trust companies registry index. Read it with Progmat, Progmat stablecoin / digital asset route, ODX, and SMTB.

Use this page for digital securities, security-token trust, beneficiary-certificate issuing trust, and trust-company platform questions.

TL;DR

Alterna Trust is a digital-securities-focused trust company established by Mitsui & Co. Digital Asset Management (MDM) and Sumitomo Mitsui Trust Bank. The SMTG English release describes Alterna Trust as a trust company specializing in digital securities and says administration of beneficiary-certificate issuing trusts plays a crucial role in ST issuance.^[source:smtg-alterna-release-2025] The MDM release says MDM built a setup under the ALTERNA brand to provide ST acquisition, operation, trust administration and sale end-to-end, while Progmat provides Progmat SaaS to MDM and Alterna Trust.^[source:mdm-alterna-release-2025] The FSA trust-company workbook lists Alterna Trust Co., Ltd. with licence date 2025-07-03, corporate number 9010001253166, and address 1-9-8 Nihonbashi Horidome-cho, Chuo-ku, Tokyo.^[source:fsa-trust-list-2026]

This is not a securities broker, exchange, or stablecoin issuer page. The useful boundary is the trustee / trust-administration role for security-token fund structures.

Group / alliance relationship

MDM side

MDM is the platform / asset-management side of the structure. Its release says MDM has built the ALTERNA service for individual investors and operates ST fund formation / management / sale. It also says its use of Progmat SaaS lets MDM complete ST management itself, reducing scheme costs and aiming to maximize returns to investors.^[source:mdm-alterna-release-2025]

Sumitomo Mitsui Trust side

SuMiTB supplies trust know-how and the trust-bank group route. SMTG release says SuMiTB and MDM entered a business alliance for digital securities, including joint management of Alterna Trust, dispatching experts / sharing know-how, forming products using ALTERNA, introducing assets including claims held or sourced by the bank, and providing funds to MDM while MDM uses SuMiTB’s sales network.^[source:smtg-alterna-release-2025]

Progmat boundary

Progmat is infrastructure, not the trust company. MDM release describes Progmat SaaS as a product enabling financial institutions to start digital-asset-related businesses such as ledger-management and custody functions without building their own blockchain / DLT nodes.^[source:mdm-alterna-release-2025]

Why standalone page matters

  1. Trust layer is explicit: Many ST pages over-emphasize platform or exchange. Alterna Trust gives FinWiki a trustee / beneficiary-certificate issuing trust anchor.
  2. It links trust banking to fintech: The page bridges smtb, progmat, ALTERNA and security-token fund issuance.
  3. It is not a soft partnership note: FSA list and company releases support a concrete regulated entity, not only a concept.
  4. It limits role confusion: Use ODX for market venue, Progmat for infrastructure, and this page for trust administration.
