Ledger and Zcash: Ironwood funding agreement and Grant #152 scope mapping
Hi everyone, major update!
In the August update we said the next post would be a bigger, formal one, covering the commercial and legal groundwork mentioned there. That work has concluded, so here is the full picture.
1. The Ironwood funding agreement
The Ironwood pivot created additional engineering work that was not anticipated by the original grant. That additional work, and only that work, is now covered by a Blockchain Integration and Funding Agreement between Ledger and Zcash Labs LLC (their announcement), under which Zcash Labs funds USD 80,000 for adapting the original Orchard-scoped deliverables to Ironwood (NU6.3).
To be explicit about governance, because it matters here:
- This is a bilateral agreement between Ledger and Zcash Labs. It is separate from, and independent of, Grant #152.
- It changes nothing about Grant #152: not the deliverables owed to the community, not ZCG’s review and acceptance process.
- Zcash Labs has no authority of any kind over Grant #152. It cannot modify, approve, or direct anything under the grant. That remains entirely between Ledger and ZCG.
- Any steps Zcash Labs may take within Zcash community processes regarding its sponsorship are its own initiative, in its sole discretion. Ledger is not a party to any such process.
2. Grant #152 deliverable mapping
As promised in August, the written mapping of the original grant scope against the Ironwood deliverables is now posted on the grant issue for ZCG’s review: Github Issue #152 Comment.
The one-line summary: every deliverable stands as originally defined in Grant #152, with the Orchard-specific components delivered as their Ironwood equivalents, since Ironwood is now the network’s shielded pool following NU6.3 activation. The comment also lists explicitly what is not covered, so there is no ambiguity at acceptance time.
3. Where delivery stands
Shielded send and receive remain complete across the stack and in QA hardening, as described in August. Release is gated on completion of the independent security audit of the device app and final QA; we are targeting end of September. The regular monthly update follows at the end of the month.
We are grateful for constant and proactive support from Tom (Zcash Labs LLC), ZCG, FPF and ZODL team. And we are looking forward to long term collaboration with Zcash community
