When someone launches a coin on pump.fun, they set a small group of options once, at the moment of creation, and every one of them stays fixed afterward. As a buyer, that matters: the settings you see on a new coin are frozen, chosen by the creator before you ever arrived. Reading those locked choices closely is where a buyer's homework starts.
Set once, locked at creation
Every setting below is permanent: "once you create your coin, this info cannot be changed" (source: Pump.fun help center). The name, the ticker, the description, the social links, the image, and the toggles all lock into the launch transaction, and the launch is the only moment a creator can set them.
That is why reading the create-time settings is worth your time: they are the coin itself, fixed from the first block. How coins are created on pump.fun gives the full picture of how a coin comes into existence around these settings.
The three toggles a creator can flip
Pump.fun changes its create form often, so treat any exact list as a snapshot rather than a permanent menu. As of 2026 the form centers on three creation-only toggles.
The first is Mayhem mode: turn it on and an autonomous trading agent trades the coin for its first 24 hours, adding volume, and it mints extra tokens to do so, which enlarges the supply (source: Pump.fun docs). It can only be set at creation and stays that way for the life of the coin. What Mayhem mode is has the full mechanics.
The second is cash back: here the creator chooses, before launch, whether the coin's creator fees flow to them or back to the people trading it. Once set, that split holds for good: "Once the token is launched, that choice is permanently locked and cannot be changed" (source: crypto.news). Cashback coins explained has the detail of what that means for a trader.
The third is pairing with USDC: instead of the usual SOL-based launch, a creator can start the coin with USDC liquidity, so its price is quoted against a stable dollar token rather than against SOL (source: Crypto Briefing). USDC-denominated launches covers what that changes for buyers.
The image, video, and banner
The coin's media is a creation-time choice too. The form takes a square image (up to 15mb), an optional video (mp4, up to 300mb), and an optional banner. Like everything else, these are added only at launch and stay as first uploaded. So a coin with a slick video and banner had those prepared before it went live, while a bare coin keeps that plain look for good. It is a small signal, but a fixed one.
An opt-in setting people miss: the tokenized agent
One thing trips people up the other way: the "tokenized agent" is a real, opt-in setting as well as the legal disclaimer of the same name in the site footer. A creator launching through the token-launcher contract can turn a coin into an Agent Token, upload a skills.md file that defines what the agent does, and set a share of the revenue the agent earns to spend buying back and burning the coin (source: Pump.fun docs). Unlike the other choices here, that share stays adjustable after launch, because the creator can change it later. So a coin flagged as a tokenized agent shows a setting the creator switched on, distinct from boilerplate that applies to every coin.
Where PUMP itself trades
These launch settings live on individual coins. PUMP, the platform's own token, is a separate instrument that trades on BloFin as the PUMP/USDT Spot pair and as a PUMPUSDT Perpetual, where the perpetual tracks the price with margin while the spot pair is the token outright. A coin's create-time settings speak to that one coin, while PUMP is a bet on pump.fun the business, so the two move for their own reasons.
What a position in either PUMP market costs is set out on BloFin's fee page, the quickest way to see the current charges.
Reading the settings as a buyer
The create-time settings are a record of decisions the creator made and then locked. Say you open a fresh coin with Mayhem mode on: that tells you an agent may trade it for a day and the supply runs larger than a plain coin, a choice the creator made at the start and kept for the coin's life. Reading them tells you what was fixed at birth, a starting point that pairs with watching what the creator's wallet does next.

Frequently asked questions
Can pump.fun creation settings be changed after launch?
No. Every setting on the create form, from the name and ticker to the toggles and media, is locked in the launch transaction. Pump.fun's help center states plainly that once a coin is created the information cannot be changed. There is no later settings page to edit them.
What settings can a creator choose on pump.fun?
A creator sets the name, ticker, description, optional social links, and the coin's image, with an optional video and banner. As of 2026 the form also offers three creation-only toggles: Mayhem mode, cash back, and pairing with USDC. The exact menu changes over time, so treat it as a snapshot.
What does Mayhem mode mean on a coin?
It means the creator opted the coin into an autonomous trading agent that trades it for its first 24 hours and mints extra tokens to do so, which increases the supply. It can only be set at creation. The full mechanics are covered in the dedicated Mayhem mode guide.
Is the tokenized agent a launch option?
Yes. By pump.fun's own documentation, the tokenized agent is a voluntary setting a creator can enable when launching through the token-launcher contract, uploading a skills.md file and setting a share of the revenue the agent earns to buy back and burn the coin. There is a legal disclaimer of the same name in the site footer, but the setting itself is a real, opt-in creation choice. That share can also be changed after launch, unlike the other settings here.
Why do creation settings matter to me as a buyer?
Because they are permanent and were chosen before you arrived. You cannot assume a setting will change, and you cannot ask the creator to flip one. Reading what a coin was launched with tells you what is fixed, which is a starting point for judging it.
