21Shares Polkadot ETF (TDOT) Review: Fee, Staking, Custody and Liquidity
TDOT is the only US spot Polkadot ETF: 0.30% fee, 80% of DOT staked with 73.5% of rewards paid out in cash, $9.5m in assets, and a share count that moved on six days in six months.
TL;DR. The 21Shares Polkadot ETF, renamed the 21Shares Polkadot Staking ETF in August 2026, listed on Nasdaq on 6 March 2026 and is still the only US spot DOT fund after Grayscale withdrew its own registration on 7 August. It charges 0.30%, had 79.72% of its DOT staked at 30 June 2026, and pays staking rewards out in cash each quarter after a 26.5% cut for the sponsor, staking providers and custodians. What the launch coverage called an $11m seed was mostly a 600,000-share position the Web3 Foundation had held since January 2025. As of 16 September 2026 the fund holds 9.65m DOT worth $9.46m across 800,000 shares, and the share count has changed on six days since listing.

The seed money was fourteen months old
Launch coverage in March said TDOT came to market seeded with $11 million. True, and it misses the interesting part. The trust was formed in October 2024, and on 3 January 2025 a single investor, Web 3.0 Technologies Foundation, the Swiss foundation behind Polkadot, bought 600,000 shares (adjusted for a later split) for $52,631,796 worth of DOT. The trust then ran privately for fourteen months, staking its DOT and paying 15% of the rewards to 21Shares.
By listing day DOT had fallen far enough that 21Shares did a four-for-one reverse split on 4 March 2026. The next day it bought 20,000 seed creation shares itself at $18.48, for $369,671. So of the 620,000 shares trading on 6 March, 600,000 belonged to the foundation and 20,000 to the sponsor. The "$11m seed" was a 2025 position marked at 2026 prices plus $0.37m of genuinely new money. The 10-Q for the quarter to 30 June 2026 shows what that repricing cost: a DOT cost basis of $53.3m against a fair value of $7.4m. Whether the foundation still holds its shares isn't disclosed. Either way, TDOT's asset base is an anchor investor's legacy position, not the product of ETF demand.
The fee, and who pays it in what
The unitary sponsor fee is 0.30% of NAV, the same rate 21Shares charges on its Sui fund TSUI and on the Hyperliquid fund in our THYP review. Among the single-issuer altcoin funds tracked on this site it sits at the cheap end: VanEck's BNB fund charges 0.39%, Canary's Litecoin and Hedera funds 0.95%.
The fee is paid in DOT, not cash, so the coin count drifts down by about 0.30% a year before staking rewards; since an amendment on 26 August 2026 it's collected at least quarterly rather than weekly. For the quarter to 30 June 2026 the sponsor fee came to $7,561. The staking fee line in the same quarter was $28,019, nearly four times as much, which tells you where the real cost of this fund sits.
Staking: how much, who does it, who gets paid
The prospectus says the trust generally intends to stake between 40% and 95% of its DOT, with the figure set by a liquidity model. In practice it has run near the top: 92.40% of holdings were staked at 31 March 2026 and 79.72% at 30 June.
Staking runs through Coinbase Crypto Services and Figment, the latter under an agreement signed on 4 May 2026. Figment's liability for slashing or missed rewards is capped at the fees it collected over the prior six months, except for gross negligence or fraud.
The economics are simpler than most staking ETFs. Of gross rewards, 26.5% goes to the sponsor, staking providers and custodians combined; the remaining 73.5% is retained by the trust and distributed to shareholders in cash at least quarterly. Compare the 30–70% range and undisclosed split on THYP, or the flat 25% Grayscale and Bitwise take on their Hyperliquid funds.
The numbers so far, from SEC filings: staking rewards of $1,441,809 in the fiscal year to 31 March 2026, mostly earned as a private trust, and $103,125 in the quarter to 30 June 2026, when the trust paid $107,510 in income distributions. For a reader used to how Ethereum ETF staking works, the difference is that TDOT pays out rather than accruing rewards into NAV.
The unbonding risk shrank in July
Until mid-2026 the case against staking most of a fund's DOT was Polkadot's 28-day unbonding period: a wave of redemptions could leave the trust unable to deliver coins for a month. Referendum 1910, enacted on 6 July 2026, cut nominator unbonding to roughly two days and removed slashing for nominators altogether. The 10-Q now describes the unbonding period as 24 to 48 hours. Redemptions still aren't instant, but a month-long liquidity problem became a settlement-cycle one. It's the biggest change in the fund's risk profile since listing.
Custody and plumbing
The 10-Q names Coinbase Custody Trust Company and BitGo Bank & Trust as the custodians holding all of the trust's DOT. 21Shares' product data as of 16 September 2026 also lists Anchorage Digital Bank and Coinbase Custody International, so the roster appears to have widened. Bank of New York Mellon is transfer agent, administrator and cash custodian; Flow Traders is the named market maker. The model is the one in how Bitcoin ETF custody works.
Two housekeeping changes landed in August 2026. The trust switched its pricing benchmark from the CME CF Polkadot-Dollar Reference Rate to the FTSE Polkadot Index on 27 August, and changed its legal name to 21Shares Polkadot Staking ETF on 25 August. Neither affects what you hold; brokers may show either name for a while.
Creations and redemptions: six days in six months
Baskets are 10,000 shares, and authorized participants can deliver cash (the trust buys DOT through a designated counterparty) or DOT in kind. Using 21Shares' own daily valuation history, the share count changed on six of the 133 valuation days between 6 March and 16 September 2026:
| Date (2026) | Shares after | Change | Approx. value at prior-day NAV |
|---|---|---|---|
| 12 March | 650,000 | +30,000 | +$0.56m |
| 9 April | 700,000 | +50,000 | +$0.77m |
| 13 April | 740,000 | +40,000 | +$0.64m |
| 17 April | 720,000 | −20,000 | −$0.32m |
| 8 June | 750,000 | +30,000 | +$0.34m |
| 10 September | 800,000 | +50,000 | +$0.74m |
Net creations since listing come to 180,000 shares, about $2.7m at the NAVs of the days they occurred. The 10-Q for April to June reports 130,000 shares issued and 30,000 redeemed, a net of 100,000, which matches the daily data once same-day creates and redeems are netted. Every other day printed zero: buyers and sellers matched on the exchange and no basket was needed. The AP's role is covered in our authorized participants guide.
Meanwhile the price did the work. NAV went from $17.87 at listing to $19.39 on 16 March, $8.99 on 18 August and $11.82 on 16 September, down 33.9% since day one; net assets went $11.08m, $6.74m, $9.46m over the same points.
Liquidity: read the spread before the AUM
A $9m fund with one market maker trades like a $9m fund. From 21Shares' daily data through 16 September 2026:
- Spread. The 30-day median bid-ask spread was 0.38% on 16 September and has stayed between 0.30% and 0.41% since April. A round trip costs more than a year of the sponsor fee.
- Volume. Median daily volume across 132 sessions is 1,654 shares, roughly $20,000 at recent prices. Forty-five sessions traded under 1,000 shares. The busiest day, 8 September, saw 23,742 shares, about $350,000.
- Premium and discount. The median close is +0.06% to NAV, the range −1.25% (17 June) to +1.86% (16 September), and only five sessions closed more than 1% away. For a fund this size that's well behaved.
The practical rule: limit orders, and don't try to move more than a few thousand shares in one print.
How 21Shares publishes holdings, and how we read them
21Shares publishes a daily valuation record for TDOT: date, units outstanding, total NAV, NAV per unit and the DOT quantity held, with history back to the listing day. Canary and VanEck, by contrast, publish today's figures and nothing older.
Our Polkadot ETF flow tracker reads that record and derives daily net flow as the change in shares outstanding multiplied by the prior day's NAV. With a single US fund, the asset total and the fund figure are the same line. Three things to keep in mind:
- The series updates once per business day, after 21Shares posts the valuation. It isn't real-time.
- Weekends and US holidays are empty, and 21Shares occasionally skips a valuation day (9 September 2026 is absent from its history), in which case the next change carries two days of activity.
- 21Shares' share count for a given day already includes that day's orders, so the flow is dated to the day the count changed, not the day before.
With six non-zero days in six months, TDOT's flow chart is a flat line with occasional steps. Read the steps, not the line: the April creations came with NAV between $14 and $16, down from $19 in mid-March, which looks more like scheduled allocation than momentum buying. Background on the asset is in our Polkadot ETF explainer, and the fund's place among the year's launches in the 2026 crypto ETF list.
Who it's for
| Pros | Cons |
|---|---|
| Only US spot DOT ETF; Grayscale withdrew its S-1 on 7 August 2026 | No competitor means no fee pressure and no second book |
| 0.30% fee, no waiver games | 0.38% median spread costs more than the fee in year one |
| Staking rewards paid in cash, 73.5% to holders, split disclosed | Cash distributions are taxable income and force DOT sales |
| Two-day unbonding since July 2026 shrinks redemption risk | Staking provider liability capped at six months of fees |
| Daily holdings and full history published by the issuer | $9.5m in assets, mostly one holder's legacy position |
TDOT makes sense for someone who wants DOT in a retirement or mandate-restricted account, prefers a cash yield to compounding, and buys in sizes the book can absorb. It makes less sense for an active trader, who pays the spread on every turn.
Risks specific to this fund
- Concentration of ownership. Six hundred thousand of the 800,000 shares were sold to one investor in 2025. If that holder redeems, the fund shrinks by three quarters in a day.
- Scale. $9.46m in assets and a $7,561 quarterly sponsor fee isn't a business. Sponsors close funds that don't grow, and TDOT's growth since listing is $2.7m of creations against a DOT price down by a third.
- Distribution drag. Paying rewards in cash means selling DOT every quarter at whatever the price happens to be, and taxable income for holders in taxable accounts.
Verdict
TDOT is a well-built fund attached to a small market. The structure is clean: a low fee, a disclosed staking policy, named custodians, daily holdings anyone can check. The problems are all about size. A median day trades $20,000, the share count has moved six times in six months, and most of the asset base predates the listing.
If you need DOT in an ETF wrapper, this is the only one, and it's a reasonable one. If you're looking for a signal about institutional Polkadot demand, the flow line will tell you more than the AUM does, and so far it's said very little. Watch the steps on our Polkadot ETF flow page; the day the foundation's position moves, you'll see it there.
