TL;DR
オルタナ信託は、Mitsui & Co. Digital Asset Management (MDM) と 三井住友信託銀行 (SMTB) が設立した digital-securities-focused trust company。SMTG English release は Alterna Trust を digital securities に特化した trust company と説明し、beneficiary-certificate issuing trust の administration が ST issuance で重要な役割を持つと述べる。^[source:smtg-alterna-release-2025] MDM release は、ALTERNA brand のもとで ST の取得・運用・受託・販売を一気通貫で提供する体制を構築し、Progmat が Progmat SaaS を MDM と Alterna Trust に提供すると説明する。^[source:mdm-alterna-release-2025] FSA trust-company workbook では、オルタナ信託株式会社が 2025-07-03 免許日、法人番号 9010001253166、所在地 東京都中央区日本橋堀留町1-9-8 として掲載される。^[source:fsa-trust-list-2026]

Digital securities trust role
| Function | FinWiki relevance |
|---|---|

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