Competition Law and Token Trading Platform Competition

Introduction

Token trading platforms—centralised cryptocurrency exchanges, decentralised exchanges, token marketplaces and hybrid trading venues—create distinctive competition-law issues because they combine financial-market functions, digital platforms, network effects, data advantages, custody services, payment infrastructure and software ecosystems.

Competition concerns may arise where a platform:

• becomes dominant because traders and token issuers prefer a large liquidity pool;
• restricts access to trading, custody or market data;
• imposes exclusivity or listing conditions on token issuers;
• engages in self-preferencing or discriminatory treatment;
• ties token trading to wallets, custody, payment or other services;
• prevents interoperability between competing platforms;
• uses transaction and order-book data to disadvantage rivals;
• coordinates fees or trading conditions through algorithms;
• acquires emerging competitors before they become effective competitive constraints; or
• exploits network effects to create entry barriers.

The analysis below focuses principally on competition-law principles applicable to token trading platforms, using established antitrust cases from digital platforms, financial markets, payment systems, technology and network industries where directly crypto-specific precedent remains comparatively limited.

1. Meaning of Token Trading Platforms

A token trading platform is an electronic marketplace through which users can buy, sell, exchange or otherwise transact in digital tokens.

They can broadly be divided into:

A. Centralised exchanges

A centralised exchange operates an order book and generally controls or intermediates:

• account creation;
• trading;
• custody;
• matching;
• withdrawals;
• listing;
• market data; and
• sometimes fiat payment services.

B. Decentralised exchanges

A decentralised exchange may rely on smart contracts and automated market makers rather than a conventional centralised order book.

Examples of competitive functions include:

• liquidity pools;
• automated pricing;
• token routing;
• governance;
• wallet connectivity; and
• transaction settlement.

C. Hybrid platforms

Hybrid models combine centralised matching or custody with blockchain-based settlement or self-custody.

The competition analysis depends upon what economic function the platform performs, rather than merely whether the underlying asset is called a "token."

2. Relevant Competition Markets

Several relevant markets may exist simultaneously.

A. Token trading market

The relevant market may be:

trading services for a particular token or class of tokens.

For example, Bitcoin trading may have different competitive conditions from trading in highly specialised utility tokens.

B. Crypto-asset exchange services

A broader market could encompass exchange services for multiple crypto-assets.

C. Spot and derivatives markets

Spot-token trading and token derivatives may constitute separate markets depending upon substitutability.

D. Token listing services

An exchange may provide a separate upstream service to token issuers:

access to exchange listing and trading infrastructure.

E. Custody services

Where an exchange holds customer assets, custody can potentially constitute a distinct service.

F. Market-data services

Real-time:

• prices;
• order books;
• transaction information;
• liquidity information; and
• trading statistics

may themselves have competitive significance.

3. Network Effects

Token exchanges frequently exhibit powerful direct and indirect network effects.

More traders can produce:

• greater liquidity;
• tighter spreads;
• more transactions;
• better price discovery; and
• greater attractiveness to additional traders.

More token issuers can also attract more users.

This can create a feedback loop:

More users → more liquidity → better execution → more users → more liquidity.

A successful platform may therefore become difficult for smaller rivals to challenge even where switching costs are not formally contractual.

4. Liquidity as a Source of Market Power

Liquidity is especially important in token trading.

A trader generally prefers an exchange where a large order can be executed without substantial price movement.

Consequently, a platform with a deep order book can have an important competitive advantage.

A dominant platform might strengthen this advantage by:

• offering preferential fees to high-volume traders;
• imposing exclusivity;
• restricting liquidity providers from using rival platforms;
• preventing cross-platform liquidity aggregation; or
• controlling essential trading data.

Competition authorities would examine whether such conduct forecloses rival platforms rather than merely reflecting legitimate competition on the merits.

5. Multi-Homing and Switching

Crypto traders can potentially maintain accounts on several exchanges.

This is known as multi-homing.

Multi-homing can constrain platform market power because users can switch between platforms.

However, effective multi-homing may be reduced by:

• withdrawal costs;
• verification requirements;
• custody arrangements;
• loyalty programmes;
• API integration costs;
• liquidity fragmentation;
• token listing restrictions;
• wallet incompatibility; and
• loss of accumulated trading benefits.

Therefore, the existence of several exchanges does not automatically establish effective competition.

6. Dominance and Market Power

A token exchange may become dominant through a combination of:

• market share;
• liquidity;
• network effects;
• user base;
• token listings;
• technological infrastructure;
• brand reputation;
• access to data;
• switching costs;
• interoperability advantages; and
• economies of scale.

Market share remains relevant, but digital-platform analysis normally requires consideration of structural and behavioural factors as well.

7. Exclusive Dealing With Token Issuers

An exchange might require a token issuer to list its token exclusively on that exchange.

For example:

"The token issuer shall not permit trading of the token on any competing exchange for three years."

Such a provision can raise concerns where the exchange possesses substantial market power.

Potential effects include:

• foreclosure of competing exchanges;
• reduced liquidity on rival platforms;
• higher entry barriers;
• reduced price discovery; and
• increased dependence of token issuers upon the dominant exchange.

The legality depends upon factors such as duration, coverage, market power, foreclosure effects and legitimate commercial justification.

8. Most-Favoured-Nation and Parity Clauses

A token exchange could require an issuer or liquidity provider not to offer better trading conditions on competing platforms.

For example:

An issuer must not provide another exchange with lower trading fees or superior token-launch terms.

Such clauses can reduce price competition between exchanges.

They may also discourage a smaller exchange from offering aggressive discounts to attract users.

Competition authorities therefore examine whether parity obligations:

• suppress price competition;
• prevent market entry;
• facilitate coordination; or
• protect an incumbent's market position.

9. Self-Preferencing

A vertically integrated crypto platform might operate:

1. an exchange;
2. a proprietary wallet;
3. a token;
4. custody services;
5. liquidity provision; and
6. token-launch services.

It could then favour its own token or affiliated services.

Examples include:

• preferential placement;
• lower fees;
• superior execution;
• preferential liquidity;
• faster listing;
• exclusive access to platform data; or
• preferential routing.

The key competition question is whether the conduct disadvantages competitors through the platform's control over an important bottleneck.

10. Tying and Bundling

A dominant exchange might condition access to one service upon purchasing another.

For example:

access to token trading is conditioned upon using the exchange's proprietary wallet.

Potentially relevant combinations include:

• exchange + wallet;
• exchange + custody;
• exchange + stablecoin;
• exchange + payment service;
• exchange + token-launch platform; and
• exchange + analytics service.

The competition analysis considers market power, separate demand, coercion, foreclosure and possible efficiencies.

11. Access to Trading APIs

Professional traders and liquidity providers frequently use APIs.

An exchange could restrict:

• order-submission APIs;
• market-data APIs;
• historical data;
• latency-sensitive access;
• algorithmic trading functionality; or
• third-party portfolio-management tools.

Where a dominant exchange controls commercially indispensable API access, discriminatory restrictions can become an abuse-of-dominance issue.

12. Market-Data Advantage

An exchange possesses highly valuable information concerning:

• trading volumes;
• order books;
• transaction flows;
• user behaviour;
• liquidity;
• price movements; and
• trading patterns.

If the exchange also competes in adjacent markets, its ability to use such information can create competitive advantages.

For example, an exchange could potentially use proprietary trading data to improve an affiliated market-making operation.

The competition issue becomes particularly significant where competitors cannot obtain equivalent data on reasonable terms.

13. Algorithmic Trading and Collusion

Algorithmic systems create novel cartel risks.

Suppose competing token exchanges use algorithms that:

• monitor competitors' prices;
• automatically adjust fees;
• respond to trading conditions; and
• avoid aggressive price competition.

Competition law may still apply even though human intervention is limited.

Technology does not automatically eliminate responsibility for coordinated conduct.

Potential issues include:

• algorithmic price coordination;
• exchange-fee coordination;
• coordinated liquidity-provider restrictions;
• information exchange; and
• hub-and-spoke arrangements.

14. Hub-and-Spoke Coordination

A large exchange could potentially become the "hub" through which information is exchanged between competing market participants.

For example:

Exchange → Market makers → Competing exchanges

If commercially sensitive information is intentionally transmitted between competitors through a common platform, competition concerns may arise.

Relevant information may include:

• intended fees;
• trading strategies;
• liquidity commitments;
• prices; and
• future commercial plans.

15. Predatory Pricing

A large exchange might temporarily charge:

• zero trading fees;
• negative fees;
• subsidised withdrawals; or
• substantial rewards.

Low prices are not inherently unlawful.

However, if a dominant platform deliberately incurs losses to eliminate rivals and subsequently exploits its strengthened market position, predatory-pricing principles may become relevant.

The analysis normally examines:

• price-cost relationship;
• duration;
• recoupment possibilities;
• exclusionary strategy; and
• market structure.

16. Margin Squeeze

A vertically integrated token platform could operate:

• an upstream liquidity or settlement service; and
• a downstream token exchange.

If it controls the upstream input and sets downstream prices in a way that prevents equally efficient competitors from operating profitably, a margin squeeze theory may arise.

17. Refusal to List Tokens

Listing can be commercially critical for token issuers.

A dominant exchange may refuse to list a token.

A refusal becomes competition-law sensitive where:

• the exchange has substantial market power;
• access is objectively indispensable;
• the platform previously supplied the relevant service;
• refusal eliminates effective competition; and
• no legitimate justification exists.

However, exchanges may also have legitimate reasons for refusing listings, including:

• technical risks;
• fraud prevention;
• regulatory compliance;
• security concerns; and
• inadequate liquidity.

18. Essential-Facility Considerations

The essential-facilities doctrine may become relevant in exceptional cases.

The claimant would generally need to establish circumstances such as:

1. control of an important facility;
2. practical indispensability;
3. inability to reasonably duplicate it;
4. exclusion of competition through denial of access; and
5. absence of adequate objective justification.

A major exchange's liquidity or infrastructure should not automatically be treated as an essential facility merely because it is commercially important.

19. Merger and Acquisition Concerns

Token platforms can acquire:

• rival exchanges;
• wallets;
• stablecoin issuers;
• blockchain infrastructure;
• market-data providers;
• liquidity providers; and
• token-launch platforms.

Competition authorities may examine:

Horizontal effects

Exchange A acquires Exchange B.

Vertical effects

Exchange A acquires a major liquidity provider.

Ecosystem effects

Exchange A acquires a wallet or infrastructure provider that can be used to disadvantage competing exchanges.

Killer-acquisition concerns

A dominant exchange might acquire a small but rapidly growing rival before it becomes an effective competitive constraint.

20. Important Case Laws

Because cryptocurrency-specific reported antitrust jurisprudence remains comparatively limited, the following cases provide important competition-law principles that can be applied to token trading platforms.

1. United States v. Visa Inc. / United States v. Mastercard Inc.

The payment-card cases demonstrate how network effects, platform structure and access restrictions can produce competition concerns.

Principle

A platform can possess substantial competitive significance because merchants and consumers participate in an interconnected network.

Relevance to token exchanges

A major exchange may similarly benefit from:

• network effects;
• liquidity;
• user participation;
• merchant/issuer relationships; and
• barriers to entry.

Restrictions preventing counterparties from using competing platforms can therefore receive close scrutiny.

2. Ohio v. American Express Co., 585 U.S. 529 (2018)

The U.S. Supreme Court considered competition in a two-sided transaction platform.

Principle

Two-sided platforms must sometimes be analysed by considering both sides of the platform because the services are interconnected.

Relevance

Token exchanges are also multi-sided platforms connecting:

• traders;
• token issuers;
• market makers;
• liquidity providers; and
• sometimes payment providers.

An antitrust assessment should therefore consider competitive effects across interconnected sides rather than examining only the trader side.

3. United States v. Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001)

Microsoft involved exclusionary conduct by a dominant technology platform.

Principle

A dominant technology company may violate competition law where it uses its control over an important platform to restrict competitive threats.

Relevance

The case is particularly relevant to token ecosystems involving:

• wallets;
• operating systems;
• exchanges;
• APIs; and
• interoperability.

A dominant exchange that uses technical restrictions to exclude competing services could raise analogous concerns.

4. United Brands Company v. Commission, Case 27/76

The European Court of Justice addressed abuse of a dominant position and refusal to supply.

Principle

A dominant undertaking has particular responsibilities not to distort effective competition through exclusionary conduct.

Relevance

The principle may become relevant where a dominant token exchange controls access to:

• listing;
• liquidity;
• trading infrastructure; or
• indispensable platform services.

5. Bronner v. Mediaprint, Case C-7/97

The ECJ developed important principles concerning refusal to provide access to infrastructure.

Principle

Not every commercially valuable facility is an essential facility. Strict conditions apply before compulsory access is required.

Relevance

The case is highly relevant to arguments that a dominant token exchange's:

• liquidity pool;
• API;
• order book;
• custody infrastructure; or
• settlement system

constitutes an indispensable facility.

6. IMS Health GmbH & Co. OHG v NDC Health, Case C-418/01

The case concerned access to intellectual property and infrastructure under exceptional circumstances.

Principle

Compulsory access to a protected or controlled resource requires demanding conditions, particularly where refusal could eliminate competition and prevent the emergence of a new product or service.

Relevance

A token platform could potentially invoke analogous arguments concerning access to:

• proprietary trading data;
• APIs;
• liquidity infrastructure;
• technical standards; or
• other platform resources.

7. Slovak Telekom a.s. v European Commission, Joined Cases C-165/19 P and C-166/19 P

The case concerned exclusionary conduct involving access to infrastructure and margin squeeze principles.

Principle

A dominant undertaking controlling an important upstream input can potentially distort downstream competition.

Relevance

A vertically integrated token ecosystem could present similar issues where the exchange controls:

• liquidity;
• custody;
• settlement;
• token infrastructure

while simultaneously competing with independent downstream platforms.

8. Google Shopping, Case T-612/17

The General Court considered Google's treatment of competing comparison-shopping services.

Principle

A dominant digital platform's use of its platform position to favour its own service over competing services can raise abuse-of-dominance concerns.

Relevance

The analogy is significant for token exchanges operating multiple services.

Possible examples include:

exchange → proprietary token → proprietary wallet → proprietary liquidity service.

Preferential ranking or access for affiliated token products could therefore attract competition scrutiny.

9. Google Android, Case T-604/18

The case concerned Google's contractual and ecosystem restrictions involving Android.

Principle

Bundling and contractual restrictions imposed by a dominant ecosystem operator can reinforce market power and impede rival platforms.

Relevance

Comparable concerns could arise where a dominant crypto ecosystem links:

• exchange access;
• wallet functionality;
• token services;
• app distribution; and
• payment infrastructure.

10. Mastercard Inc. v Merricks, Case C-164/21

The case concerns competition-law damages arising from Mastercard's interchange arrangements.

Principle

Competition infringements in complex multi-sided payment systems can produce widespread economic effects.

Relevance

Token exchanges similarly operate interconnected markets involving traders, liquidity providers, token issuers and payment infrastructure.

21. Competition Issues Specific to Decentralised Exchanges

Decentralised exchanges introduce an additional question:

Who is the undertaking responsible for the potentially anticompetitive conduct?

Possible actors include:

• developers;
• governance organisations;
• token holders;
• liquidity providers;
• front-end operators;
• protocol foundations; and
• intermediary service providers.

Decentralisation does not necessarily make competition law irrelevant.

The critical issue is whether identifiable economic actors exercise sufficient control or coordination over the relevant commercial conduct.

22. DAO Governance and Competition Law

A decentralised autonomous organisation may make decisions concerning:

• fees;
• liquidity incentives;
• token listings;
• protocol access;
• interoperability;
• governance rights; and
• transaction routing.

If competing market participants collectively coordinate commercial conditions through governance mechanisms, competition-law questions can arise.

Particularly sensitive subjects include:

• common fee schedules;
• restrictions on competing protocols;
• exclusion of rival liquidity providers;
• allocation of customers; and
• exchange-specific territorial restrictions.

23. Stablecoin Integration

Stablecoins may function as settlement instruments across token exchanges.

An exchange controlling a widely used stablecoin could potentially gain power over:

• settlement;
• liquidity;
• trading pairs;
• transaction costs; and
• interoperability.

Competition issues may therefore arise from tying an exchange's services to its proprietary stablecoin or restricting access to competing settlement mechanisms.

24. Token Listing Fees

High listing fees can create barriers to entry for smaller token issuers.

Competition authorities may examine whether:

• fees reflect genuine costs;
• the platform possesses market power;
• fees discriminate between issuers;
• affiliated tokens receive preferential treatment; and
• the pricing strategy excludes rival listing venues.

High prices alone are not necessarily anticompetitive; market power and exclusionary effects remain important.

25. Trading Fee Discrimination

An exchange may provide different fees to:

• institutional traders;
• retail users;
• affiliated market makers;
• proprietary trading operations; and
• token issuers.

Differential pricing can be legitimate.

Competition concerns arise particularly where discriminatory pricing:

• disadvantages rival liquidity providers;
• excludes competitors;
• exploits a dependent trading group; or
• favours an affiliated business without objective justification.

26. Interoperability

Interoperability is particularly important for token markets.

Users may need to transfer assets between:

• exchanges;
• wallets;
• blockchains;
• liquidity pools; and
• payment systems.

A dominant platform could potentially restrict interoperability to increase switching costs.

Possible remedies include:

• API access;
• standardised data formats;
• wallet interoperability;
• transfer functionality; and
• non-discriminatory technical standards.

27. Data Portability

Trading history and transaction data can have significant competitive value.

If users cannot easily transfer:

• trading records;
• portfolio information;
• API configurations;
• transaction history; or
• identity information,

switching costs can increase.

Data portability can therefore operate as a competition-enhancing mechanism.

28. Competition and Consumer Protection

Competition law and consumer protection may overlap.

A dominant token platform could potentially engage in conduct involving:

• misleading fee disclosures;
• hidden spreads;
• discriminatory execution;
• unfair token promotion;
• deceptive ranking;
• manipulation of trading interfaces; or
• restrictions on withdrawals.

The competition analysis should distinguish consumer-protection violations from competition-law infringements, even though the same conduct may implicate both.

29. Possible Competition Remedies

Competition authorities could potentially consider:

Structural remedies

• divestiture;
• separation of exchange and proprietary trading operations;
• separation of custody and exchange functions.

Behavioural remedies

• non-discriminatory listing;
• API access;
• interoperability;
• prohibition of exclusivity;
• data-access obligations;
• transparency requirements.

Merger remedies

• divestiture of overlapping businesses;
• access commitments;
• licensing;
• firewall arrangements;
• restrictions on data combination.

30. Compliance Framework for Token Trading Platforms

A competition-compliance programme should include:

Market power assessment

Regularly assess:

• market share;
• liquidity;
• network effects;
• switching costs;
• entry barriers.

Contract review

Review:

• exclusivity;
• parity clauses;
• MFN provisions;
• loyalty incentives;
• listing agreements.

Data governance

Separate competitively sensitive information from affiliated businesses.

API governance

Ensure access policies are:

• transparent;
• objective;
• non-discriminatory.

Algorithmic controls

Audit algorithms for:

• coordinated pricing;
• discriminatory access;
• exclusionary behaviour.

M&A review

Examine acquisitions of:

• wallets;
• exchanges;
• token issuers;
• liquidity providers;
• market-data providers.

Conclusion

Token trading platforms represent a particularly complex application of competition law because liquidity, network effects, data, interoperability and ecosystem integration can reinforce one another. A platform may initially compete aggressively through low fees and technological innovation but later acquire substantial market power because traders, issuers and liquidity providers gravitate toward the platform with the deepest liquidity.

The most significant competition-law questions therefore concern access, exclusion, vertical integration, data advantages, interoperability, algorithmic coordination, exclusivity and mergers.
