Hello all!
We’ve submitted a retroactive grant application to the Coinholder Retroactive Grants Program for Valargroup’s funding of external audits and AI tools on the Ironwood emergency response. Note, none of this grant request is payment to team members or company margin, and are solely to external third parties.
Requested Amount: $599,000
The External audits for:
- All Ironwood changes (Zellic)
- Any Orchard Soundness bug (Zellic, Ottersec)
- Any soundness bug in the stack (Ottersec)
- Sapling (Zellic)
were a total cost of $499,000.
The remaining $100k cost was spent on v12.sh, to help review all of the Zcash stack and the rapid Ironwood developments.
The Zellic Ironwood reports can be found here: Release Zcash Reports (July) by justin-chon · Pull Request #245 · Zellic/publications · GitHub

The current Sapling audit report draft can be found here: https://zakura.com/audits/zellic/Zcash-sapling.pdf
These audits were coordinated in an emergency, starting ASAP and interfering with the auditors existing engagements.
