# Data Sources

> Where our data comes from and how we prioritize sources

We combine issuer-reported data, on-chain data, and third-party pricing feeds to build a comprehensive view of each tokenized asset. Each data type has a different source hierarchy and validation process.

## Issuer-reported data

The majority of reference data on our platform (asset details, legal structure, fees, service providers) comes directly from issuers and platforms.

**What issuers provide:**

* Asset descriptions, names, and tickers
* Legal entity information (issuer name, jurisdiction, legal structure, CIK, LEI)
* Fee structures (management fees, performance fees, subscription/redemption fees)
* Fund details (open/closed-end, lockup period, investor eligibility)
* Service provider relationships (custodians, auditors, fund administrators, transfer agents)
* NAV data (for assets where NAV is not observable on-chain)
* Transparency and audit reports

**Verification process:**
All issuer-reported data is reviewed by our team before publication. We cross-reference against public filings, offering documents, and official issuer websites. Data is not published until verified.

**Privacy handling:**
If an issuer wants to keep certain holder-related data private, we offer options to anonymize sensitive fields. Issuers can submit data with customizable privacy settings.

## On-chain data

On-chain data provides the quantitative metrics for each token: supply, holders, transfers, and transaction activity.

**What we track:**

* Token supply and balances
* Transfer events (mints, burns, peer-to-peer transfers)
* Holder addresses and activity
* Bridge events (cross-chain token movements)

On-chain data is deterministic. Given the same block, the same values are always produced. We cross-reference against public block explorers (e.g., [Etherscan](https://etherscan.io/), [Solscan](https://solscan.io/)) to validate accuracy.

**Data partners:** We work with [Dune](https://dune.com/) and [SonarX](https://sonarx.com/) for on-chain data infrastructure.

## Pricing data

Pricing data determines NAV, market value, and yield calculations. Different metrics come from different sources:

* **Exchange aggregators:** Market prices for tokens traded on exchanges, aggregated across multiple venues
* **Issuer-reported NAV:** Net asset value reported directly by the issuer or fund administrator
* **On-chain price feeds:** Prices derived from on-chain sources (e.g., oracle feeds, DEX prices)

## Third-party data

We supplement our primary sources with data from:

* **Block explorers** for cross-referencing on-chain metrics
* **Public filings** such as SEC EDGAR and regulatory registrations
* **Rating agencies** including S\&P and Bluechip where available
* **Industry databases** for asset classification and sector mapping

## Source prioritization

When multiple sources provide conflicting data, we resolve conflicts using this priority order:

| Priority | Source                              | Rationale                                       |
| -------- | ----------------------------------- | ----------------------------------------------- |
| 1        | Public filings / official documents | Legally binding, audited                        |
| 2        | Issuer-reported data                | Direct from source, verified by our team        |
| 3        | On-chain data                       | Deterministic, independently verifiable         |
| 4        | Exchange aggregators                | Market-derived, subject to liquidity conditions |
| 5        | Third-party databases               | Useful for enrichment, but not authoritative    |
