Grayscale put a number on a problem that has quietly sat inside its Ethereum Staking Mini ETF for months: roughly 161,000 ETH, worth close to $1.6 billion, has been earning nothing while it waits as a redemption and fee buffer. On August 6, the fund’s sponsor signed paperwork meant to put most of that idle balance to work — and to start sending the proceeds to shareholders as cash.
What actually changed
Grayscale Investments Sponsors, LLC and CSC Delaware Trust Company executed a Third Amended and Restated Declaration of Trust and Trust Agreement for the fund on August 6, replacing the version dated September 25, 2025. A Prospectus Supplement covering the change followed on August 7.
The operative change is narrow but consequential: the trust must now convert staking rewards to cash no less often than quarterly and distribute the net proceeds — after trust expenses and a separate staking fee still to be disclosed — to shareholders. Grayscale has said it intends to pay out monthly, with quarterly as the contractual floor.
Staking itself becomes closer to the default state for the fund’s holdings under the new language, with carve-outs for coins the trust needs to keep liquid for redemptions, fee payments and network emergencies. That is a shift from treating staking as incidental to treating it as the fund’s normal operating posture, with un-staked ETH becoming the exception rather than the rule.
Why the timing lines up with a tax deadline
Staking a fund’s assets used to carry a real cost: doing so risked pulling the trust out of grantor-trust tax treatment, which would have meant taxation at the fund level before any distribution reached investors. The IRS published rules in November 2025 that created a path for crypto funds to stake without triggering that outcome, but funds needed to formally restructure to rely on it.
Reporting on Grayscale’s filing timeline placed the relevant compliance window closing on August 10 — four days after the amendment was signed. That is a tight turnaround, and it explains why the paperwork landed when it did rather than at a more routine moment in the fund’s calendar. Investors should treat the August 10 date as reported rather than as an official Grayscale-published deadline, since the trust does not appear to have issued its own plain-language statement fixing that date.
The yield on offer so far
Grayscale has already been staking part of the fund’s ETH ahead of this amendment. The company has reported net staking rewards running at roughly 2.61% annually after fees, with $27.3 million in cumulative net rewards earned to date. That figure will move once the 161,000 idle ETH is folded into the staking pool, since a larger staked base changes both the reward total and, potentially, the blended net yield after the new staking fee is applied.
What this does and doesn’t tell shareholders
| Question | What we know | What we don’t know yet |
|---|---|---|
| Will payouts start immediately? | The amendment is signed and effective | No confirmed first distribution date |
| What is the staking fee? | A separate fee will apply on top of expenses | Exact rate has not been disclosed |
| Will all 161,000 ETH get staked? | Most of it is expected to move off the sidelines | A buffer will remain for redemptions and emergencies |
| Does this change the fund’s price exposure? | No — this is a yield mechanism, not a hedge | ETH price risk is unchanged |
The distinction in that last row matters. A quarterly or monthly cash payout is a return of staking yield, not a reduction in the fund’s exposure to ETH’s price. Shareholders still carry the same downside if the token falls; the amendment only changes how the reward layer on top of that exposure gets delivered and taxed.
The broader signal for staked ETFs
Grayscale’s move follows a pattern other issuers have been working through since the IRS guidance opened the door: funds that hold a proof-of-stake asset have an incentive to stake as much of it as operationally safe, because unstaked coins are a drag on the product’s competitiveness against peers that do stake. As more issuers finish their own trust amendments, monthly or quarterly cash distributions from staking rewards may become a standard feature of staked crypto ETFs rather than a differentiator for any single fund.
For now, Grayscale has cleared the structural hurdle. The open questions — the staking fee, the exact distribution schedule, and how much of the 161,000 ETH buffer actually gets deployed — will only be answered as the fund publishes its first post-amendment distributions.
Bottom line
This is a plumbing change, not a price catalyst. Grayscale has rewritten the rules governing roughly $1.6 billion in ETH so that staking rewards flow to shareholders as cash on a monthly-to-quarterly cycle, using a tax structure the IRS opened up in late 2025. It does not alter the fund’s exposure to ETH’s price, and the size of the eventual payout depends on a staking fee that has not yet been published. Investors holding the fund should watch for the first distribution notice and the disclosed fee rate before assuming a specific net yield.
