Proof for Tokenized Investments: VIRIDIS Issues VIA Security with Filedgr AssetID

How issuers can document the purchase of tokenized investments so that it can be independently verified by tax advisors using VIRIDIS's VIA Security as an example.

Proof for Tokenized Investments: VIRIDIS Issues VIA Security with Filedgr AssetID

VIRIDIS Green-Tech Investment AG has issued VIA Security, a tokenized investment certificate linked to the VIRIDIS Green-Tech portfolio, with Filedgr AssetID. The record of the purchase value, time, and terms of each subscription therefore exists as a dataset whose integrity can be independently verified, rather than as a confirmation letter issued by the issuer about itself.

A token is only as reliable as the dataset that supports it. This rarely becomes apparent at the time of purchase, but rather months later. As soon as a subscriber has to explain to their tax advisor what they acquired, when, and at what value.

Why Isn't a Confirmation from the Issuer Enough for the Tax Advisor?

Because it is a self-declaration: a document the issuer issues about itself. Formally valid, but structurally weak. For a tax advisor who has to account for a capital investment, a dataset that remains verifiable independently of the issuer is a significantly better starting point.

In the case of VIA Security, there is another factor: it is issued to companies. At the end of every subscription, there is therefore not only an investor, but also an accounting department, a tax advisor, and, if necessary, an auditor who must be able to clearly trace the purchase value, acquisition date, terms, and allocation to the specific token.

The second problem is practical. The effort does not scale. With a handful of subscribers, individual letters can still be prepared. As soon as the group grows, the exception becomes a recurring manual process. Per subscriber, per tranche, per request. And every additional hurdle in the subscription process competes with the familiar reflex on the other side: transfer the money, receive a PDF, done.

What Is Filedgr AssetID?

Filedgr AssetID is the verification infrastructure that enables issuers to capture the facts of a token issuance at the source, make them accessible in a controlled manner, and keep their integrity verifiable from issuance through review by tax advisors, auditors, or other authorized parties.

Isn't a Blockchain Hash Enough?

No. A hash and an Asset ID answer different questions. A hash proves that a dataset has remained unchanged. It says nothing about which asset it describes, who issued it, or under what terms.

Filedgr AssetID connects proof of integrity with the identity of the asset —more specifically, what type of asset it is, who issued it, when, and under what conditions and makes this connection verifiable by authorized third parties. This is exactly the information a tax advisor needs and that a transaction hash alone does not provide.

How Does the Proof Work in a Token Issuance?

In three steps:

  1. Capture: Record the issuance. With every issuance of VIA Security, the relevant facts are captured at the point of origin and provided with a cryptographic signature: purchase value, time, terms, and allocation to the respective subscriber. The dataset is anchored on-chain. No subsequent compilation from emails and payment receipts.
  2. Control: Manage access. The subscriber receives access to the dataset relating to their own position and can share it selectively: with their tax advisor, their own accounting department, or an auditor. Selectively, so that instead of viewing the register of all subscribers, the recipient can only view this one record relating to this one position.
  3. Prove: Verify integrity. The recipient can verify the integrity of the dataset without having to trust the issuer. The signature and record history are traceable; subsequent changes would be detectable. A statement about the transaction becomes verifiable proof.

What Does This Change for the Issuer?

Three things. The proof for each subscriber is created as a byproduct of the issuance rather than as a separate manual step. The subscriber can provide their tax advisor with something that goes beyond the company's own confirmation. And the subscription process requires less explanation for corporate clients because the proof follows the familiar logic of verifiable investment documentation rather than that of a crypto transaction.

“A letter from the issuer is not enough. With the token live, we wanted to give our investors and their tax advisers more than just a letter from us. They needed a structured, verifiable record they could review." Josef Z. Köhl, Managing Director, VIA Security of Viridis

Important: The regulatory classification of VIA Security as a tokenized investment certificate is a statement by VIRIDIS. Filedgr AssetID verifies the integrity and identity of the issuance dataset, not the legal status of the token itself.

Which Issuers Is This Relevant For?

For anyone who tokenizes an asset and issues it to multiple subscribers, particularly when those subscribers are companies and must themselves provide documentation to accounting departments, tax advisors, or auditors. Security tokens, fund shares, tokenized real-world assets: the same gap exists wherever there is a difference between “we have the data” and “we can prove it.” The pattern is not limited to Green-Tech investments.

How Can AssetID Be Used for Your Own Issuance?

Anyone issuing tokens to corporate clients and looking for a reliable, scalable basis for proof can see how the AssetID model can be applied to their own issuance structure.
