Retroactive Grant Application - Frontier Compute Zcash Security Research and Remediation Pack

I submitted Frontier Compute’s Q3 Coinholder Retroactive Grant application:

Requested amount: $136,250

This application includes only security work that is accepted, public, merged, or released.

COMPLETED LIGHTWALLETD WORK - $56,250

  1. GHSA-9p9r-mggr-8q9g

I am the sole accepted reporter. I submitted it on 5 May 2026. The fix shipped in lightwalletd 0.5.2. Valuation: $18,750, the Supporting Infrastructure Medium base schedule then in force.

  1. GHSA-x4m7-3gpp-xc36

I authored and maintained the Frontier Compute report and preserve every additional public credit. I submitted it on 28 April 2026, after the VDI launch. I claim only the accepted paths fixed and released in lightwalletd 0.5.0. The unresolved residual is excluded. Valuation: $37,500, the Supporting Infrastructure High base schedule then in force.

I used the applicable bountyzcash-to-VDI process and the base VDI price grid in force on each disclosure date. I did not prorate an accepted severity band by path count, and I did not claim the discretionary 50 percent uplift. These are valuation benchmarks, not claims of an existing award.

COMPLETED ZODL WALLET-REMEDIATION WORK - $80,000

The public completion evidence consists of these approved and merged changes:

ZODL maintainers wrote and reviewed the patches. I claim Frontier Compute’s security research, responsible disclosure, control specification, adversarial verification, and fix-to-release tracking. I do not claim authorship of maintainer code.

I ask ZODL to confirm the report-to-fix linkage. Any item they do not confirm should be removed from the funded scope.

DISCLOSURES

  • No private advisory identifiers, exploit details, or confidential finding inventory are included.

  • No open, draft, rejected, disputed, unmerged, or unresolved work is valued.

  • All public credits are preserved.

  • Frontier Compute LLC and I would receive the grant.

  • Frontier Compute has received no Coinholder Retroactive Grant funding for this work.

  • Our separate ZAP1 application concerns unrelated attestation tooling.

  • Any overlapping bounty payment will be disclosed and deducted dollar-for-dollar before disbursement.

  • There will be no double recovery.

I stayed with this work from discovery and responsible disclosure through remediation review, merge, release ancestry, and residual-risk verification.
