Innovation / Unique Traceable Identifier
Interoperability infrastructure / identity layer
From fund creation to subscription, redemption, transfer and settlement, FundStream proposes a common identity and transaction-reference framework across private market infrastructures.
Concept / proposed network service
Disconnected infrastructure
From fund formation through distribution, subscription, confirmation and settlement, private-market information crosses multiple organizations, each with its own systems of record, onboarding data, message conventions and reference numbers.
Existing identifiers solve critical—but distinct—problems. An LEI identifies eligible legal entities. An ISIN identifies a financial instrument, where one is assigned. Neither, by itself, establishes a consistent network-wide reference for every fund relationship and every operational transaction across the full post-investment journey.
The consequences are practical: repeated mapping, avoidable exceptions, slower investigations and fragmented lifecycle visibility. More integration alone will not fix inconsistent identity.
Where fragmentation appears
Records emerge before all external identifiers have been assigned.
Each platform may maintain a separate product and account reference.
Instructions, confirmations and settlement updates are often reconciled through separate keys.
Changes must be linked back to the same underlying fund and event.
The missing layer is not another registry of everything. It is a shared way to recognize what already exists.
Two complementary layers
01 / Persistent fund identity
Assigned on onboarding — ideally at fund creation — to uniquely reference a fund or compartment within FundStream, including before external identifiers are available. Linked to the umbrella, manager, domicile, LEI and applicable share-class ISINs.
FS-FND-7K4P9Q2M
Illustrative proprietary FundStream reference. Not an official ISO standard.
02 / Transaction-level identity
Issued when an instruction is accepted by the network. Persistent across routed messages, status changes, acknowledgments, allocation, confirmation and settlement coordination, with linked references for revisions or related transactions.
FS-TXN-2026-9M2J7WQ4
A FundStream-native reference, distinct from any mandated ISO 23897 derivatives UTI.
Important naming distinction
“Universal Transaction Identifier (UTI)” is used in regulated derivatives reporting. This conceptual page uses Network Transaction Identifier (NTI) for private-fund activity until any formal standards mapping is established. A regulatory UTI can be stored separately where applicable.
Lifecycle continuity
FundStream captures an enduring reference at fund formation or first network onboarding, then links every subsequent transaction without taking ownership of the fund registry or back-office books and records.
01
Fund created
Fund or compartment registered; legal structure recorded
02
UFI assigned
Internal identity and external identifiers mapped
03
Instruction routed
NTI assigned; fund and share class referenced
04
Lifecycle updates
Parties exchange acknowledgments, validation and confirmation
05
Settlement status
Payment and asset rail references linked for traceability
Interoperability map
Eligible legal entities and fund relationships
Persistent fund / compartment reference and identifier mapping
Share class or instrument where assigned
Each NTI references a UFI and, where relevant, the applicable share-class ISIN; externally supplied trade or payment identifiers remain preserved.
Interactive demonstration
Switch between a sample fund registry record and its transaction history. All examples are fictional, local demonstration data — not live network records.
Fund identity record / example
FS-FND-7K4P9Q2M
Domicile: Luxembourg · Entity type: Sub-fund / compartment
Identifier status: Provisional — awaiting external instrument identifier
Share class ISIN: Not yet assigned · Legal entity LEI: Subject to eligibility and verification
The UFI remains unchanged as official identifiers are issued, corrected or updated.
Operational controls
Authority to request creation; duplicate detection; jurisdiction and entity validation; fund/compartment hierarchy; lifecycle states; effective-dated external reference mappings; corrections without ID reuse.
Issuer authority, idempotency, immutable original NTI, message IDs versus business transaction IDs, linked reversals and amendments, event audit trail, data-access permissions and reconciliation keys.
FundStream would serve as a neutral messaging and identity coordination layer — not an issuer of official ISINs or LEIs, a legal fund register, a transfer agent, or a settlement system.
For infrastructure partners
Designed for asset managers, distributors, transfer agents, administrators, custodians and settlement infrastructures to exchange consistent references while maintaining their systems of record.
