The largest asset manager in the world, BlackRock, has filed an updated 19b-4 form for its Spot Ethereum ETF application.

The amended filings come as exchanges were reportedly asked by the SEC to amend their 19b-4s earlier this week. Form 19b-4s are filed to let the SEC know about a proposed rule change and are among the documents that need the agency’s greenlight before spot ether ETFs can become effective.
