Adding DeFi to your 401k: How BlackRock’s staked Ethereum ETF rewires access to ETH rewards

BlackRock registered the iShares Staked Ethereum Trust in Delaware on Nov. 19, opening a path toward the firm’s first staked Ethereum ETF in the US.

The state-level trust registration does not constitute a formal Securities Act of 1933 application. Still, it positions BlackRock to launch a yield-bearing ETH product once the SEC permits staking inside ETF wrappers.

The filing follows a separate proposal earlier this year that would retrofit BlackRock’s existing iShares Ethereum Trust ETF to stake a portion of its ETH through Coinbase Custody if regulators approve.

BlackRock now pursues two parallel tracks: adding staking to its live spot ETH ETF and creating a dedicated staked Ethereum trust from scratch.

Yield gap drives the push

The first wave of US spot Ethereum ETFs launched in 2024 without staking after the SEC required issuers to remove the feature.

Those funds charge management fees of 0.15% to 0.25%, VanEck’s Ethereum ETF charges 0.20%, while Fidelity’s ETF and iShares ETHA both charge 0.25%. They hold ETH in institutional custody and track the price with no on-chain staking yield passed through to investors.

On-chain, roughly 30% of Ethereum’s circulating supply is staked, and network-level rewards have run just under 3% annualized in recent weeks, per reference indices such as Compass’s STYETH and MarketVector’s STKR.

Investors who buy a spot ETH ETF today forfeit that 3% yield if the token trades flat.

BlackRock enters a market where three distinct staking structures have emerged. The REX-Osprey ETH + Staking ETF trades under the ticker ESK as an actively managed 1940 Act fund that stakes at least 50% of its holdings, charging an all-in fee of 1.28%.

VanEck filed a Lido Staked Ethereum ETF structured as a grantor trust that holds stETH rather than native ETH.

Grayscale disclosed that its flagship Ethereum Trust can retain up to 23% of staking rewards as additional compensation, while the Ethereum Mini Trust ETF can retain up to 6% of staking rewards.

Pricing, access, and custody as competitive levers

BlackRock’s existing 0.25% fee on ETHA provides a baseline. A dedicated staked ETH trust gives BlackRock three options: keep the 0.25% sponsor fee and pass nearly all staking yield through to investors, add an explicit cut of staking rewards as a second fee layer, or deploy temporary fee waivers to capture market share before normalizing rates.

A staked ETH ETF solves a distribution problem for institutions, advisers, and retirement platforms that cannot access DeFi protocols or lack the operational infrastructure to self-stake.

A spot ETF that performs native staking converts on-chain yield into a total-return line item compatible with 401(k) accounts and model portfolios.

Investors who buy a staked ETF may capture roughly 2% to 3% annually after fees, even if the token price remains flat.

BlackRock appears set to use Coinbase Custody for both ether storage and staking, concentrating all operations inside a single US-regulated counterparty.

The Nasdaq filing identifies Coinbase as both custodian and staking provider. REX-Osprey uses US Bank with external validators, while VanEck’s Lido fund depends on Lido’s smart contracts and a separate stETH custodian.

Regulators may favor BlackRock’s single-counterparty model over structures that route staking through DeFi protocols.

Regulatory timing is still uncertain

The SEC forced issuers to strip staking from the first ETH ETFs because specific staking programs might constitute unregistered securities offerings.

BlackRock’s Delaware trust positions the firm at the front of the queue for when that stance softens, but it has no effective registration statement or approved exchange rule.

Regulators face three open questions. The first is whether they will permit native staking in a 1933 Act commodity trust or require it to be placed in 1940 Act structures.

The second is whether they will treat liquid staking tokens like stETH as equivalent to holding underlying ETH. The third is how much fee extraction from staking they will tolerate before a product crosses into actively managed yield strategy territory.

BlackRock’s filing opens three competitive fronts. On pricing, the firm’s scale will compress margins, but the real contest centers on what percentage of staking rewards sponsors retain.

On access, a staked ETH ETF brings validator-level yields inside brokerage accounts that will never touch DeFi.

On custody, every staked ETF proposal concentrates staking into a handful of custodians. As more ETH migrates into ETF shells, more of the network’s staking power will be held by institutional keys.
