It depends on where you are and, far more than people expect, on what you say about the flow. Automating trades through wallets you own is not by itself a crime in most jurisdictions. Presenting that flow to other people as independent demand, or pairing it with a price claim, is where the exposure lives. This is a description of how the question is usually framed, not legal advice, and it is not a substitute for a lawyer in your own jurisdiction.
Short version
- The automation is not the issue. Software trading on your behalf is ordinary.
- The description is the issue. Flow presented as organic interest is a representation about a fact.
- The 2024 US cases turned on selling the activity as market making while describing it to investors as demand.
- Jurisdiction matters enormously. Rules for token markets differ sharply between the US, EU, UK and elsewhere.
- Never promise a price, a trending slot or a return. That is the claim that converts a marketing spend into something else.
The four layers
The question sounds like one thing and is actually four, which is why the answers people give each other contradict one another.
- Is it legal to run software that trades for you? Effectively everywhere, yes. Automated trading is ordinary and not remotely novel.
- Is it legal to trade with yourself? On a regulated venue, in a regulated instrument, self matched trades are specifically prohibited. On permissionless token markets the position is far less settled and varies by jurisdiction.
- Is it legal to tell people the resulting volume is organic demand? This is where the trouble is. That is a factual representation, and if it is false and material, it is the kind of statement that fraud and manipulation rules are built around.
- Is it legal to do it with a token that is a security in your jurisdiction? Then the whole securities framework applies, and the analysis is nothing like the one above.
Most arguments on this topic are two people answering different numbers on that list.
What the 2024 cases were about
In October 2024 United States prosecutors brought charges against several firms that had been selling services described as market making for token projects. The conduct at issue was generating trading volume between wallets under common control, and presenting the result as genuine market activity.
Two things in that are worth holding on to. First, nobody was charged for writing a trading bot. Second, the framing of the service mattered: the offering was sold under a respectable label and the output was described to investors as something it was not. That is a disclosure and deception question far more than a technology one, and it is the same line drawn in volume bot vs market maker.
Where jurisdictions differ
| Region | General posture | The live question |
|---|---|---|
| United States | Aggressive on fraud and manipulation theories | Whether the token is a security, and what buyers were told |
| European Union | Market abuse rules extended to crypto assets under MiCA | Whether the activity gives false or misleading signals |
| United Kingdom | Financial promotion rules bite on marketing claims | How the offering and the token are promoted |
| Elsewhere | Highly variable, from unregulated to prohibited | Whether any token market regime exists at all |
The pattern across all of these is the same: regimes that reach this activity reach it through rules about misleading signals and misleading statements, not through rules about software. If you never make the statement, you are in a very different position from someone who builds a pitch deck around the volume figure.
The claims that create exposure
These are the specific things that turn a marketing spend into a much harder conversation. They are worth reading as a list of things never to write down.
- Describing routed volume to investors or buyers as organic interest, real traders or genuine demand.
- Promising a price, a price floor or a return in connection with a session.
- Promising a trending slot, which is neither yours nor the tool provider's to sell.
- Using the volume figure in fundraising material without saying how it was produced.
- Combining routed flow with a coordinated sell into whoever the visibility brings in.
Notice that only the last of those is about the trading at all. Four out of five are about what is said. That ratio is the single most useful thing to take away from this page.
What a careful operator does
Get local advice before spending
The answer genuinely varies by jurisdiction and by what the token is. A short conversation with a lawyer who knows your market is cheaper than the alternative.
Keep the marketing claims separate from the flow
Promote the token on what it is. Do not build a pitch around a volume number, and never present routed flow as independent participation.
Never promise a price
No tool controls it, so any promise about it is false at the moment it is made, whatever happens afterwards.
Keep records of what you ran
Every trade is on chain anyway. Knowing exactly what you configured and when is worth having if anyone ever asks.
Assume it is all visible
It is. Treat every session as something you would be comfortable explaining, because the chain makes explaining it the only option.
Our position
PumpWave routes the volume you configure across the wallets you configure and charges a flat 1% of the target from 100 SOL up. We state what the session does on chain and what it costs, because those are the only parts anyone can verify. We do not claim a trending slot, a price, a holder base or a profit, and we do not describe routed flow as demand. We also do not know your local law, and nothing here is legal advice.
Questions people actually ask
Is wash trading illegal in crypto?
On regulated venues and in regulated instruments, self matched trading is prohibited outright. In permissionless token markets the position varies by jurisdiction, and the regimes that do reach it usually do so through rules about misleading signals and misleading statements rather than rules about the trading mechanics.
Did anyone actually get charged for this?
Yes - in October 2024 US prosecutors charged several firms selling volume generation services described as market making for token projects. The cases turned on the activity being presented as genuine market interest.
Does it matter if the token is not a security?
Whether the token is a security matters a great deal, because securities rules bring an entire additional framework. It does not make the question disappear, since fraud and consumer protection rules can apply to statements about any asset.
Is it safer if I disclose that I ran a volume session?
Disclosure removes the specific problem of a false representation, which is the largest single exposure. It does not resolve every question, and whether it helps in your jurisdiction is a question for a lawyer there.
What about running a session on my own token with no investors?
The fewer people relying on the number, the narrower the exposure, but a public token market always has people reading the chart. The fact that you did not personally pitch anyone does not mean nobody acted on the signal.
Can the provider be liable rather than me?
Provider liability and client liability are both possible, and they are not alternatives. The 2024 actions were brought against service providers. That does not shift responsibility away from the person who commissioned the work and made the claims.
Run one and watch it land
Paste a mint, shape the session, see the exact fee before you fund anything. Flat 1% from 100 SOL, no install, no seed phrase.
