Mayhem Mode is an optional Pump.fun setting that a coin's creator switches on at launch, which hands an automated trading agent the job of buying and selling that coin through its first 24 hours of life, adding artificial volume and price movement to a brand-new token that would otherwise trade on its own.
With the mode active, a coin launches with two billion tokens instead of the usual one billion, and the agent controls that second billion as its inventory for the period. Whatever remains unsold when the 24 hours conclude gets destroyed, which makes this one of the more recent additions to the wider pump.fun risks. The unusual part is that the price a buyer sees can be moved by software instead of by other traders.
The mechanism is the easy part. The confusion begins because Pump.fun describes what that agent does across three separate surfaces, and the three accounts diverge.
How the agent trades a new coin
When a creator switches Mayhem Mode on at launch, Pump.fun mints a second billion tokens and hands them to an automated agent, which buys and sells the coin through its first 24 hours and then destroys whatever it leaves unsold. The coin's starting price and liquidity stay identical to any other new coin, so everything looks the same at launch.
Picture the opening minutes of two coins side by side. A standard Pump.fun coin arrives with one billion tokens, and only the public trades against them. A Mayhem coin arrives with two billion, and the extra billion becomes the agent's ammunition, spent until the 24 hours expire, when every remaining agent token is burned. Pump.fun's explainer, last updated November 12, 2025, sets out the operating rules (source: Pump.fun Mayhem Mode explainer). The mode works only on coins launched through the pump.fun bonding curve, and it can be enabled only while a coin is being created. The document states that the agent trades the coin "by buying and selling the coin with equal probabilities in a random walk" through the period, and that it may skip some coins that opt in. A random walk describes a path where each step is decided by chance, independent of the step before, so on that description the buys and sells resemble a coin flip with an even, directionless spread (source: Investopedia).
The agent is one instance of the broader category of AI trading bots, except that this bot belongs to the platform, an operator's agent rather than a private trader's. Its reach is capped by fixed limits: a ceiling on how much of a coin it can buy, how much it can sell, and how many trades it can place within a set interval. That is the identical launch machinery behind ordinary Solana memecoins, with a single automated participant added on top.
What the disclaimer says about the agent's trading
The legal disclaimer, last updated April 21, 2026, quietly revises the most important detail (source: Pump.fun Mayhem Mode disclaimer). Where the explainer describes the trading as an equal-probability random walk, the disclaimer states that the agent may sell, on average, slightly more or slightly less than it buys, and that "the amount by which the bot favors (or disfavors) buying or selling is determined on a discretionary basis."
Discretionary and equal-probability are different claims. Equal probability means the odds of a buy and a sale are fixed and even. Discretionary means an operator can bias those odds, and can change that bias over time and across different coins. The disclaimer is explicit that the result is something a trader should treat as unpredictable: it warns that the bot trades at random intervals and for random amounts, and that participants should avoid basing their own buying or selling on what they expect the bot to do.
The same document spells out the guardrails that the marketing copy skips. Trades happen at most once per second per coin. The mode ends on one of two conditions, when enough time has passed since launch or when the bot exceeds a set number of trades on that coin. Enabling it is one of the coin creation settings a launcher selects, and it is a one-way launch choice that stays fixed once the coin is live.
Auto and Manual: who is really firing the trades
The live product page adds a complication that both documents omit (source: Pump.fun Mayhem product page). The page header reads "An AI agent trades your coin for its first 24 hours," and then splits the feature in two: "Auto runs itself. Manual fires when you say." Auto is the hands-off version, where the agent trades on its own through the period. Manual is the opposite arrangement, where the creator personally triggers each trade.
That distinction matters because the word autonomous recurs through the explainer. Reading the documentation alone, you picture a self-directed program. Reading the product page, you discover that a human can occupy the controls, deciding when the coin is bought or sold during its opening day. A Manual coin's volume still carries the Mayhem label and comes from that extra billion tokens inside the first 24 hours, but the timing is a person's decision rather than a machine's.
The coin's label and the size of its volume both stay silent on which version was used. From the outside, an Auto coin and a Manual coin look identical.
So is it random, or is it steered?
When a platform's own pages contradict each other, the prudent move is to adopt the least flattering account that also carries the most authority, and to identify which surface answers which question. On the behavior of the agent, the disclaimer prevails, because it is the most recent of the three and it is the document written to be legally binding. So treat the trading as steered rather than as an impartial coin flip.
That conclusion carries real weight. A true random walk has equal-probability steps and each step independent of the last, which is exactly the picture the November explainer presents and exactly the picture the April disclaimer takes back. The disclaimer's discretionary-basis language means the buy-to-sell balance can be leaned in a particular direction.
On the separate question of which party executes the trades, the product page is the surface that governs, because it is the live interface a creator actually uses. It states that a person can operate the agent in Manual, so autonomous is a default setup rather than a guarantee.
| Surface | Updated | Agent behavior |
|---|---|---|
| Explainer | November 2025 | equal-odds random walk |
| Disclaimer | April 2026 | discretionary skew |
| Product page | live | Auto or Manual |
The PUMP token itself trades on BloFin as PUMP/USDT, where prices come from an open order book instead of a launch-time agent, and the fee schedule shows what a position costs before you open one.
What Mayhem Mode changes for a buyer
For someone weighing whether to buy a Mayhem coin, the main point is that the early trading is partly engineered, so the usual signals become much less reliable. On Solana, a token's supply is set by its mint account, so minting a second billion tokens is a genuine on-chain change rather than a cosmetic display trick (source: Solana token documentation). Those extra tokens are real sellable supply held by the agent, and when the agent sells, that supply enters the same liquidity pool everyone else trades against.
The disclaimer says the uncomfortable part out loud, stating that the mode adds nothing to a token's value even while it actively trades one. Elevated early volume can look like real demand, yet part of it is the agent working through its inventory on its own schedule. That is exactly where telling genuine interest from manufactured activity gets hard, the same problem that runs through fake tickers and honeypots, where the surface signal and the underlying reality diverge.
A token listed on an exchange is an established one that trades against an order book, where the price movements come from many independent participants rather than from a launch-time agent working through freshly minted supply. That is a different risk profile from a first-day coin whose volume is partly produced by a single program running under a fixed trade cap and a 24-hour limit. The practical check is small: a coin's Mayhem status is shown on its own page, so a buyer can confirm whether the first day's trading has an automated hand before deciding anything.

Frequently asked questions
Does a coin keep the Mayhem label after the first 24 hours?
Yes. Once Mayhem Mode ends, the coin still carries the Mayhem tag, and it keeps the larger two-billion supply it launched with, because the additional tokens were minted at creation. The disclaimer notes that a coin created in the mode may hold a higher or lower supply than a standard coin, and it shows the tag even after the mode goes inactive on it. Seeing the label therefore points to how the coin was built, and the agent may be idle at that moment.
Does the coin's creator earn fees from the agent's trades?
The bot's trades sit outside the normal fee flow. The disclaimer states that trades executed by the bot skip Pump Platform fees, including the fees that would otherwise go to the token's creator. The agent's activity is also left off the public fees page, since any profit it makes is set aside as an insurance fund rather than counted as ordinary protocol revenue.
Is every coin that opts in actually traded by the agent?
The agent trades only a subset of the coins that opt in. Only a fixed maximum number of coins can be in Mayhem Mode at once, and that ceiling stays flat even as more coins opt in. When more coins request the agent than it can handle, it randomly selects which ones to trade, based partly on their suitability. A creator can switch the mode on and still see the agent skip the coin entirely.
Can Mayhem Mode be switched off or restarted after launch?
Mayhem Mode is one-way in both directions. A creator selects the mode during creation, the only window to add it, and removal is unavailable once the coin is live. It is equally one-way at the end: once the mode has finished for a coin, whether through the time limit or the trade limit, it stays off for that same coin permanently, and the agent's remaining tokens are burned.
What happens to tokens people send to the agent's wallet?
Sending tokens to the agent achieves nothing helpful. It leaves the agent's odds of trading the coin unchanged, and it leaves an ineligible coin ineligible. If the tokens are Mayhem-enabled and still within their first 24 hours, the agent burns them when that window closes. If they are ordinary tokens or an expired Mayhem coin, they simply sit in the agent's wallet indefinitely.
Where can you check whether a coin is running Mayhem Mode?
On the coin's own page, Pump.fun shows a coin's Mayhem status in the pump.fun web app, the Pump.fun mobile app, or Terminal. Pump.fun also maintains a Mayhem overview that lists active Mayhem coins and recent agent trades, so the feature stays visible before you buy.
