21Shares has filed an SEC filing to list the 21Shares SEI ETF, giving US investors regulated exposure to the SEI token from the Sei blockchain. The fund would hold SEI and may generate staking rewards by staking a portion of its assets, subject to regulatory clearance. Coinbase Custody Trust Company is named as custodian, with Coinbase Inc. prime broker handling trading operations. A rival application from Canary Capital is already on file, setting up a race for early-market share. The October 2025 SEC deadline looms for decisions on multiple altcoin ETFs, including the 21Shares SEI ETF.
Staking rewards potential
The 21Shares SEI ETF aims to offer more than price tracking by exploring on-chain staking rewards sourced from the Sei blockchain. 21Shares notes it has not finalized whether staking can operate within the public trust, pending regulator feedback and operational considerations. If permitted, staking rewards could enhance returns and offset fees. Investors should weigh validator risks, slashing, and reward variability before assuming a yield. The 21Shares SEI ETF would disclose how staking is managed if approval is secured.
SEC filing timeline
The 21Shares SEI ETF enters a high-stakes review cycle with an October 2025 SEC deadline in view. The agency will assess market integrity, custody, and whether staking mechanics fit the trust’s structure. Industry voices, including Krishnendu Chatterjee, expect more altcoin ETFs to clear in late 2025 as frameworks mature. Still, ETF approval is not guaranteed, and timelines can shift. The 21Shares SEI ETF must show robust compliance and investor protections to advance.
Coinbase custody and prime broker
Custody can make or break a crypto fund. The SEC filing lists Coinbase Custody Trust Company for safekeeping and cold storage, a setup familiar to institutions. The filing also names Coinbase Inc. prime broker for trading services, supporting liquidity and execution. This mirrors patterns seen in other crypto funds that rely on Coinbase’s infrastructure. For the 21Shares SEI ETF, this pairing aims to reduce operational risk and inspire confidence.
US investors access
The 21Shares SEI ETF would let US investors gain SEI exposure through standard brokerage accounts. That removes the need to self-custody SEI token holdings or manage exchange risks. If staking rewards are approved, the fund could package yield in a simple wrapper. The 21Shares SEI ETF may appeal to both retail traders and RIAs seeking diversified altcoin ETFs. Expenses, tracking, and any yield mechanics will be key comparison points.
Sei blockchain fundamentals
Sei targets high-throughput trading use cases, positioning itself as a fast layer-1. The SEI token ranks around 74th by market cap at roughly $1.82 billion. At about $0.30, SEI trades well below its $1.14 all-time high, down roughly 73.7% from March 2024. The 21Shares SEI ETF would track SEI’s performance while managing custody and, potentially, staking. As always, token volatility will drive short-term fund dynamics.
Canary Capital competition
Canary Capital filed a similar SEI ETF in May 2025, highlighting rising interest in altcoin ETFs. Competition may spur sharper fee structures and clearer staking disclosures. The 21Shares SEI ETF benefits from brand recognition and an established product lineup. However, the first mover, if any, could lock in liquidity advantages. Both applicants must navigate the same crypto regulation hurdles.
Crypto regulation signals
Regulators are gradually setting clearer rules for crypto funds, custody, and disclosures. Smoother surveillance-sharing and cleaner market data have aided Bitcoin and Ethereum products. For the 21Shares SEI ETF, staking details will be a focal point of crypto regulation. Transparent validator policies and risk controls could influence SEC comfort. A green light would signal broader acceptance of token-utility features in funds.
21Shares SEI ETF outlook
With Coinbase infrastructure and a clear thesis, the 21Shares SEI ETF stands positioned for a pivotal review. The fund’s prospects hinge on whether staking rewards can operate in a registered trust. Investor demand for altcoin ETFs is rising, as our coverage has shown with recent staking-oriented filings. The October 2025 SEC deadline will be a key moment for the 21Shares SEI ETF. Win or lose, the process could set templates for future token-specific ETFs.
