What is Mayhem Mode?

Mayhem Mode is a pump.fun launch option in which an autonomous AI trading agent buys and sells the coin during its first 24 hours. It can only be switched on when the coin is created, never afterwards.

pump.fun calls it an experimental beta and says the agent isn't guaranteed to trade every Mayhem coin. Everything here is from pump.fun's Mayhem Mode page, last updated on 12 November 2025 and read on 14 November 2026.

How does the agent trade?

The agent buys and sells the coin with equal probability, in a random walk, using the extra billion tokens and SOL from pump.fun's own balance sheet. pump.fun says it adds volume and price movement to early coins.

It has hard caps on how much SOL of a coin it can buy, how much it can sell, and how many trades it can make in a given time.
It pays no pump.fun protocol fees on its own trades.
Its trading wallet is public: BwWK17cbHxwWBKZkUYvzxLcNQ1YVyaFezduWbtm2de6s, as pump.fun discloses it.
Tokens sent to the agent during a coin's first 24 hours are burned at the end and don't make it trade more.

Volume isn't demand

Trades by the agent show up as volume and price moves like anyone's. They come from pump.fun's agent, not from new buyers, so don't present them as interest in the coin.

What does Mayhem Mode cost?

Mayhem Mode adds no fee for the creator or traders beyond pump.fun's usual ones. A Mayhem launch does need a little more SOL for its accounts, and pump.fun requires a first buy of at least 0.06 SOL.

pump.fun sends the protocol fees from Mayhem coins to a separate wallet that funds the agent's insurance, and doesn't count them on its public revenue page. The rest of pump.fun's fees are in pump.fun fees, explained.

How do I turn on Mayhem Mode?

Mayhem Mode is chosen in the coin's creation transaction. pump.fun's page said in November 2025 that its own web and mobile apps couldn't switch it on yet, but any tool that builds the creation can.

In memetools, open Launch and pick pump.fun.
Fill in the coin, and set a first buy of at least 0.06 SOL.
Switch on Mayhem. It can't be added later.
Approve the launch as usual.

In memetools, Mayhem can't be combined with a coin paired with a token other than SOL. To check whether any coin has Mayhem on, look at its page on pump.fun. The rest of the launch is in Launch a memecoin on pump.fun.

Risks

pump.fun names the main risk itself: the extra billion tokens can leave some holders unable to sell into the bonding curve. Mayhem Mode is a beta, and nothing here is financial advice.

If the agent sells more than it buys, more tokens are in circulation than the curve can absorb, and if everyone sells, some may not be able to sell into the curve. pump.fun says that once a coin graduates to PumpSwap, it can always be sold for SOL.
Price moves in the first 24 hours may be the agent's, not the market's.
The agent may not trade a given coin at all.
pump.fun can change or end the feature, and its page was last updated in November 2025.
