The Challenge

As TAC Fund expanded its onchain footprint, it faced growing requirements from counterparties, integrators, and risk systems for transparent, independently verifiable data.

Key challenges included:

1. 01
   Providing clear, holdings-level visibility into underlying assets without relying on opaque disclosures
2. 02
   Demonstrating how asset valuations and prices were constructed and updated over time
3. 03
   Supporting automated risk management for lending markets and onchain integrations
4. 04
   Monitoring asset changes, valuation updates, and data availability in real time

Without a verifiable data layer, TAC Fund risked slower integrations, higher operational overhead, and reduced confidence from market participants.

Why Chronicle

TAC Fund selected Chronicle as its data infrastructure partner to serve as a neutral, verifiable source of truth for both asset-level data and market pricing.

Chronicle was chosen for three core reasons:

1. 01

   Independent asset verification:

   Proof of Asset enables third parties to verify underlying assets and holdings-level data without relying on trust-based disclosures
2. 02

   Transparent data construction:

   All price feeds and asset models are defined by explicit, public data models
3. 03

   Production-grade operations:

   Live monitoring, alerts, and validator transparency support institutional oversight

Chronicle’s infrastructure is built on more than eight years of continuous oracle operation originating from MakerDAO, giving TAC Fund confidence in long-term reliability.

Solution

1. 01

   Direct Data Sourcing

   Chronicle connects directly to trusted market venues, custodians, administrators, and service providers, retrieving price and holdings-level data at defined intervals.
2. 02

   Transparent Data Models

   Each asset is governed by a clearly defined data model that specifies:

   • Source selection and weighting
   • Model type (market, fundamental, or hybrid)
   • Risk tier classification (high, mid, or low)

   These models are publicly visible on the Chronicle Dashboard.

3. 03

   Validator-Signed Publication

   Data is signed and delivered by Chronicle’s named validator set using cost-efficient, scalable Schnorr-based signatures, ensuring integrity without unnecessary gas overhead.
4. 04

   Continuous Monitoring

   Chronicle continuously monitors price deviation, data availability, and validator participation, surfacing alerts and status indicators in real time.

Results

By integrating Chronicle into its production stack, TAC Fund achieved measurable improvements across operations and market engagement:

Looking Ahead

TAC Fund continues to expand its use of Chronicle as additional products and asset classes are brought onchain.

Planned next steps include:

1. 01
   Extending Proof of Asset coverage across new funds
2. 02
   Scaling price feed usage across additional chains and execution environments
3. 03
   Leveraging Chronicle monitoring signals to support deeper automation and risk controls

Chronicle remains a long-term data infrastructure partner for TAC Fund, supporting growth through verifiable, resilient, and transparent data.
