Buried in an amended filing is a specific number: roughly 200,000 ZEC. That's the potential scale disclosed in Grayscale's latest amended filing for its Zcash ETF, revealing that parent company Digital Currency Group (DCG) is in talks to inject this amount into the fund.

What stands out here is the related-party angle. DCG is Grayscale's parent company, and now it's named in the firm's own filing as a potential ZEC supplier. This arrangement lays bare, in a regulatory document, exactly who's helping fill up the fund.

That said, the filing is also clear that this roughly 200,000 ZEC deal remains nonbinding — meaning both sides are still in discussions, with no legally binding commitment in place yet, and the quantity and timeline could still shift in future filings.

For now, that's all the public information there is. Whether the deal goes through, and when it might close, will depend on what Grayscale discloses in future filings.
