As a professional translator, I would translate this news article into English as follows:
According to the update filed on Tuesday with the US Securities and Exchange Commission (SEC) by Fidelity, the proposed Ethereum (ETH) collateral for its planned Ether ETF holding has been canceled. In the previous filing, Fidelity had indicated its intention to pledge a portion of the trust assets to “one or more” infrastructure providers. However, the updated filing on Tuesday explicitly states that it will not pledge the custodied Ethereum.
