TETH Review: 21Shares Ethereum Staking ETF

TETH suits investors who want staking income from an ether fund and care about who runs the validators and on what terms.

TETH has no overall rating under CryptoSlate’s Ethereum ETF methodology, version eth-1.1, at the September 24, 2026 data cutoff. Five pillars are scored. The custody pillar is pending, and the method withholds the overall until every pillar is resolved.

The custody pillar is pending because of one contract. Coinbase Crypto Services, one of TETH’s three staking providers, agrees to reimburse a “Covered Slashing Penalty” when one of its listed service failures occurs. The filed agreement never defines that term, and no schedule that might define it is attached. Without the definition, the public filing does not show how much slashing that promise covers, so the method cannot grade it.

Figment reimburses any slashing penalty applied to the trust’s ether, whatever the cause, up to a cap tied to six months of fees. Twinstake reimburses slashing caused by its own service failures, including double-signing.

The custody assessment can be completed when 21Shares publishes a definition that establishes the scope of this reimbursement.

At the CoinDesk Composite Ether Staking Rate of 2.6178% on September 23, 2026, TETH’s ongoing sponsor fee plus its staking cut on the staked share would cost 0.582% of fund assets a year. This combined-cost figure is for comparison only.

TETH holds ether so that its shares follow ether’s price, less expenses, and it adds the staking rewards the trust receives. It holds the ether itself and uses no futures contracts.

The fund launched in July 2024 as the 21Shares Core Ethereum ETF under the ticker CETH. It was later renamed the 21Shares Ethereum ETF, and took its current name, with “Staking” added, in August 2026.

Shareholders own an interest in the trust. They can hold and trade that security, but they do not control the private keys to its ether.

Benchmark and How to Check Tracking

Since August 27, 2026, TETH has valued its ether using the FTSE Ethereum Index. Before that it used the CME CF Ether-Dollar Reference Rate – New York Variant. The benchmark sets the daily price used to calculate net asset value.

Net asset value, or NAV, is the value of the trust’s assets after liabilities, divided by the number of shares. Staking rewards are paid out in cash, so NAV alone understates what a shareholder earned. To judge tracking, compare the NAV return with the benchmark. To see what staking added, compare total return, including distributions, with the NAV return. The benchmark change in August 2026 affects any comparison that spans that date.

TETH stakes part of its ether through three named providers. Staking commits ether to validators that help run the Ethereum network, which pays rewards for that work.

The 2.60% “rewards rate” on the 21Shares page is a network-wide average from stakingrewards.com, not the fund’s own return.

A fall in ether’s market price can outweigh any staking income. The exchange listing offers no protection against that price risk.

Who Holds TETH’s Ether?

TETH’s latest quarterly report and prospectus supplement name four ether custodians: Coinbase Custody Trust Company, BitGo Bank & Trust, BitGo New York Trust Company and Anchorage Digital Bank. The 21Shares fund page lists a different set, including Coinbase Custody International. We follow the SEC filings.

Each custodian keeps the trust’s ether separate from its own assets. Each custodian’s contract also has at least one clause, for example on following instructions or on compromised access keys, where the custodian is liable only for gross negligence. That caps the safekeeping part of the custody score at 5 of 10.

Staking providers do not hold the trust’s ether. They run validators for ether that stays with the custodians.

Fund Structure and Regulatory Status

TETH is a Delaware statutory trust and is not registered under the Investment Company Act of 1940. Calling it an ETF does not give it the protections of a fund registered under that act.

Besides the sponsor fee, TETH withholds part of its staking rewards, and trading the shares adds costs of its own.

The sponsor extended the fee waiver through October 8, 2027. Without that waiver, the ongoing 0.21% charge on a constant hypothetical $10,000 fee base for a full year would be $21, and at the 2.6178% reference staking rate the 25% cut on 57% staked ether adds about $37, for roughly $58 before the waiver and trading costs. During the waiver the sponsor-fee component is zero. Your costs move with the value of the holding and the network’s staking rate, and trading costs come on top.

TETH trades on Cboe BZX. Brokerage access varies by account and location. Some brokers may still show the fund under an older name, so confirm the ticker before placing an order.

Share Price and NAV

The share price can sit above NAV, called a premium, or below it, called a discount. A small fund can trade with wider spreads, which raises the cost of getting in and out. When authorized participants create or redeem shares with the trust, the market price tends to move back toward NAV.

Ether Withdrawals and Retail Shares

Buying a share does not put ether into a wallet you control. Retail investors buy and sell shares on the market. Authorized participants create and redeem shares with the trust in blocks. That process gives an ordinary shareholder no way to withdraw ether personally.

Staking ether yourself lets you choose the validator and hold the keys, with full responsibility for the wallet. A staking service runs the validator for you, under its own terms.

TETH vs ETH

Grayscale’s Ethereum Staking Mini ETF (ETH) has the lowest combined cost among the staking funds with an overall rating.

ETH keeps far more of its staking rewards and stakes a larger share. TETH is the one with public contracts that pay back slashing losses from two of its providers.

The pillar scores and supporting fund terms were reviewed on September 25, 2026, using ETH methodology version eth-1.1 and a September 24 data cutoff. Market and staking figures carry their own dates in the rating. The reporting review covers the quarter ended June 30, 2026.

We reviewed the 21Shares fund page, the trust’s SEC filings, including its annual and quarterly reports, prospectus supplements and the filed custody and staking agreements, and third-party fund data, checked on September 24, 2026. The assessment covers fund structure, costs, custody terms and staking terms. It does not include an executed trade or an inspection of private custody systems.
