6.6 Regulation Grayscale于2026年8月7日迅速撤回Cardano、Hedera和Polkadot ETF的S-1申请，未说明具体原因，也未发行任何证券。
根据SEC记录，Grayscale于2026年8月7日撤回了三只计划中的山寨币ETF（Cardano、Hedera和Polkadot）的S-1注册声明，所有文件在190秒内被接受。撤回文件显示，Grayscale无意推进这些产品的份额发行，相关注册声明尚未生效，未发行或出售任何证券。 此次撤回未给出具体商业或监管原因。此前，NYSE Arca和纳斯达克已于2025年底撤回了这些ETF的相关交易所上市提案。 Grayscale的其他山寨币ETF申请（如Bittensor、Aave、BNB、NEAR和Zcash）仍处于初步阶段。此举显示山寨币ETF领域存在不确定性，或将影响未来提案及投资者情绪。
