Asset management company 21Shares has recently filed an application with the Securities and Exchange Commission (SEC) to launch a Polkadot (DOT) exchange-traded fund (ETF). According to the filing on January 31, 2025, the goal is to list the 21Shares Polkadot Trust on the Cboe BZX crypto exchange, with Coinbase acting as the custodian of the DOT. However, there are potential risks associated with the Polkadot network that could compel the regulator to shut down this fund if it is approved.
