Code of Conduct

Part X – Code of Conduct – Principles for Market Integrity


These Additional Principles must be read in conjunction with GDF’s
 Overarching Principles and the GDF Taxonomy. Any capitalised terms used but not defined herein shall have the same meaning given to them in the GDF Overarching Principles and the GDF Taxonomy.


Goal of the Principles for Market Integrity

GDF believes in the importance of the development of global principles of good practice in cryptoasset markets, in order to provide a common set of guidelines that promote the integrity and effective functioning of these markets.

The Principles for Market Integrity are intended to promote a robust, fair, liquid and adequately transparent market in which participants are able to effectively transact at competitive prices that reflect available market information. This Code is thematic, not focused on a particular type of activity in the cryptoasset market (like custody or token issuance, for example) but looking at behaviours that need to be demonstrated by multiple market actors in their market-making, facing, dealing, trading and supporting roles in order to ensure overall integrity.

We appreciate that different aspects of the Principles need to be undertaken and upheld by different market actors who are described here as the “Market Participants”. Given the different roles that Market Participants play in the cryptoasset market, the principles follow a “Waterfall Framework”, meaning that they specify principles that are relevant to different participants according to their functions.

The top of each section may include principles relevant for all Market Participants (“Universal Principles”), followed by principles that are only relevant for certain Market Participants (“Specific Principles”).

We would anticipate that all types of Market Participants can accede to this Code, committing themselves to the Universal Principles as well as the particular Specific Principles which are documented for their type of organisation.

[Note on Market Participants: The breadth of participants is clear from the list. Some types of participants listed have other GDF Codes of Conduct which apply specifically to them and/or their activities – for example Corporate Issuers who may be issuing security tokens should refer to the Code of Conduct for Security Tokens, organisations providing cryptoasset custody services should refer to the Code of Conduct for Custody. In order to avoid overlap, we have not reconsidered the detail of responsibilities of Market Participants to the extent that their activities are covered by other Codes of Conduct.]

2. Confidential Information means information not in the public domain, received or created by a Market Participant, and shall include information which is restricted by legal or contractual obligations or terms to which the Market Participant is subject.

Insider Information means information of a precise nature, which has not been made public, relating, directly or indirectly, to one or more cryptoassets, and which, if made public, would likely have a significant effect on the prices of those cryptoassets or on the price of related cryptoassets (the use of which, in connection with cryptoasset trading activity, shall be referred to as “Insider Trading”).

5. Information Asymmetry means that insider actors, via Inside Information, know more about a project’s future prospects than outsiders/investors. Unequal access to information can lead to:

I. timing trades and decisions based on Insider Information

II. profiting from the use of Insider Information

6. Market Integrity means the preservation of fair and orderly cryptoasset markets which are appropriately defended against manipulation and abuse, such that public confidence and investor protection within those markets is maintained.

B. Spoofing, where traders place excessively large orders to create an illusion of supply (pessimism) or demand (optimism) before cancelling these orders, which can manipulate prices.

C. Layering, which is similar to spoofing but defined by large numbers of fake quotes.

D. Pump and Dump schemes, where perpetrators engage in coordinated buying and/or receive tokens in exchange for promoting them, creating hype and excessive optimism (pump), and later sell the tokens (dump) before the market adjusts the price back downward and mainstream investors lose their money

E. Front-running orders, where trading platform operators may use insider information to take advantage of attractive buy and sell orders before customers have an opportunity to do so

F. New crypto-specific market manipulation schemes unique to digital asset trading, as they are discovered and typologized, including but not limited to cross-market abuse and cross-asset wash-trading.

Universal Principle:

We agree that different trading products and strategies have different risk profiles and that some products and strategies may be more likely to induce Market Manipulation behaviours.

When defining actions, which may entail a conflict of interest, we will assess the existence of the following circumstances during the performance of a service:

● a relevant person making or likely to make a financial gain or avoid a financial loss on account of a client.

● interests of Trading Platform providers, operators, or a relevant person in the provision of a service to a client, or with regard to the outcome of a service provided on behalf of a client, distinct from the client’s interests.

● Trading Platform providers, operators, or a relevant person having a financial or other incentive to favor the interests of one client over the interests of another client.

● Trading Platform providers, operators, or a relevant person having business interests or being involved in the same area of business as the client.

● Trading Platform providers, operators, or a relevant person receiving, in connection with the service provided to a client, inducements from a third party which are not part of the standard commission or fee for that service.
