Rule 462(d) regulatory

"filed pursuant to Rule 462(d) under the Securities Act"

A Securities and Exchange Commission procedural rule that lets a company quickly register additional shares by re-using an already effective registration filing, rather than submitting a full new application. For investors this matters because it speeds up the issuance of more stock—similar to printing extra tickets from an approved batch—so it can increase supply, dilute existing ownership, and signal a near-term capital raise or financing plan.

Power of Attorney legal

"Power of Attorney Each person whose signature appears below"

A power of attorney is a legal document that allows one person to make decisions and act on behalf of another person, often in financial or legal matters. It’s like giving someone a trusted helper or agent the authority to handle important tasks if you are unable to do so yourself. This matters to investors because it can impact how their assets are managed or transferred if they become unable to oversee their affairs.

FAQ

What did ETHB file in this Post-Effective Amendment?

The filing adds exhibits to the S-1 registration statement, including a staking addendum and power of attorney. The amendment is limited to additional exhibits under Rule 462(d), and it does not change Part I or the prospectus text aside from the listed exhibit additions.

Does the amendment change the ETF prospectus or offering terms for ETHB?

No. The amendment states it does not modify Part I or Part II of the registration statement other than adding exhibits. The prospectus and the balance of Part II have been omitted from this filing because only exhibits are being added.

Which specific exhibits were added to ETHB's registration statement?

Exhibit 10.11 is an Amended and Restated Staking Addendum to the Coinbase Custody Custodial Services Agreement and Exhibit 24.1 is a Power of Attorney. Both exhibits are filed with this Post-Effective Amendment No. 1 under Rule 462(d).

When will the registered securities for ETHB be offered to the public?

The filing states sales may commence "as soon as practicable after this Registration Statement becomes effective." There is no pricing or share amount in this amendment; timing is tied to effectiveness of the registration statement.
