## Milestone 1 — Coinspect audit completed

As part of **Milestone 1** , we **completed** an independent security audit with **Coinspect** for TYKORA’s initial architecture (DoC + USDRIF vaults, with yield routed to Tropykus). Coinspect delivered findings and recommendations, we implemented all required fixes, and Coinspect completed the **final verification** of the remediations.

Because of the complexity of the contracts, the audit process took longer than originally expected — but it is **100% completed**.

## Tropykus shutdown impact

During the final audit process, Tropykus announced the shutdown of services. This had a major impact on TYKORA, since (as described in our whitepaper) Tropykus was the yield source used to generate rewards.

## Strategy modularity and the Sovryn pivot

From the beginning, TYKORA was designed so that **Tropykus was not the only possible yield source**. The protocol architecture allows deploying a **new strategy contract** pointing to a different yield provider, while keeping the core TYKORA Prize Vault logic intact.

Following the Tropykus shutdown, we evaluated alternatives and found a viable path with **Sovryn**. We now have the **new Sovryn strategy implemented and tested** , and **the DoC vault is already enabled in the TYKORA dApp using Sovryn as the yield source**.

## USDRIF temporarily unavailable

The downside is that, at the moment, **Sovryn does not provide yield markets for USDRIF** , so the **USDRIF vault will not be available for now**.

We also reviewed other potential options (e.g., LayerBank), but currently those do not support yield for both DoC and USDRIF in a way that fits TYKORA’s requirements. So, at this time, **Sovryn is the only viable route**.

## Remaining work

At this stage, the remaining work is focused on the **new Sovryn strategy**. Coinspect has already completed an **initial review** of this strategy and is **ready to proceed with the full audit** once we give the go-ahead.

Before we trigger that final audit step, we’re currently waiting on Sovryn to confirm a few technical details related to underlying behavior/assumptions so we can finalize the strategy parameters and implementation with full confidence. As soon as those clarifications are resolved, we will greenlight Coinspect to complete the strategy audit.

**JXLabs will cover the full cost of this additional Coinspect audit for the Sovryn strategy** (beyond Milestone 1), so the community can rely on a complete and independently reviewed production stack before we proceed further.

## Community feedback request

Given these changes, we’d really appreciate the community’s opinion:

- Does the Sovryn approach make sense as the best available path forward?
- Are you comfortable with TYKORA moving forward **with DoC only** for now (until USDRIF yield options exist)?
- Is there another ecosystem provider you believe we should evaluate as a yield source for USDRIF?

Thanks again for the support and for helping us navigate a major external dependency change mid-process. We’re happy to answer any questions and share any additional detail the community would find helpful.
