Re: Cboe Digital Exchange, LLC Rule Certification

Submission Number CDE-2023-05E

Dear Mr. Kirkpatrick:

Pursuant to Section 5c(c)(1) of the Commodity Exchange Act, as amended (“Act”), and Regulation

40.6(a) of the regulations promulgated by the Commodity Futures Trading Commission (“CFTC” or 

“Commission”) under the Act, Cboe Digital Exchange, LLC (“CDE” or “Exchange”) hereby submits this 

rule change to unwind the amendments made by an emergency rule filing submitted by CDE on September 

29, 2023 (“Emergency Rule Filing”) by delisting its physically-settled ETH and BTC futures contracts (the 

“Products”) and removing certain updates to the CDE rules. This rule change will become effective on 

November 13, 2023.

Products

On September 29, 2023, CDE submitted the Emergency Rule Filing to re-certify the Products. This 

filing was marked certified as of October 16, 2023. Upon emergency re-certification there was no trading 

and no open interest in the Products. Since then, CDE has removed and no longer intends to list the Products.

Rule Changes

As part of the Emergency Rule Filing, CDE made certain rule updates tied to trading hours and 

block trading hours in Rule 1101 and 1102, which govern the Products’ terms. CDE is removing the rule 

updates pertaining to the re-certified Products made by the Emergency Rule Filing. The specific updates to 

remove the changes made by the Emergency Rule Filing are reflected in Exhibit A.

Core Principle Compliance

CDE believes that this submission to unwind the changes made by the Emergency Rule Filing , 

including the delisting of the Products and removal of certain changes to are consistent with DCM Core 

Principles under Section 5 of the Act. In particular, CDE believes that unwinding the changes made by the 

Emergency Rule Filing is consistent with the following DCM Core Principles:

DCM Core Principle 4 (Prevention of Market Disruption) because the Products did not have any 

open interest before or after the certification of the Emergency Rule Filing; and 

DCM Core Principle 7 (Availability of General Information) because the CDE website will reflect 

that the Products are no longer listed and the revised rules will make clear that the Products are no longer 

listed. CDE also has provided notice to participants of the discontinued Products.
