21Shares Polkadot ETF (TDOT) is an exchange-traded product issued by 21Shares AG that seeks to track the price performance of Polkadot (DOT), a blockchain protocol enabling cross-chain interoperability, data transfer, and decentralized application development. The fund holds DOT tokens as its primary asset, providing investors with exposure to Polkadot's ecosystem without direct cryptocurrency custody; it employs a physically backed structure with assets held by qualified custodians and trades on major exchanges like Cboe BZX. 21Shares offers a suite of spot crypto ETPs including those for Bitcoin, Ethereum, Solana, XRP, Litecoin, Cardano, Avalanche, and others, alongside staking products and DeFi-focused funds; services encompass institutional-grade custody, regulatory-compliant issuance, and secondary market liquidity provision. Founded in 2018 and headquartered in Zurich, Switzerland, the company operates globally across Europe, the United States, and Asia-Pacific regions, targeting institutional investors, financial advisors, and high-net-worth individuals in the digital asset investment space. Recent developments include the U.S. launch of the 21Shares Polkadot ETF (TDOT) in early 2025 following SEC approval of spot Polkadot ETFs, expansion of its U.S. product lineup with additional altcoin ETPs amid growing regulatory clarity, and a strategic partnership with Coinbase Custody for enhanced asset security in North American offerings as of late 2025.
