pump.fun is a launchpad on the Solana blockchain where anyone can create and trade meme coins in seconds. Token creation is free and takes a few clicks, which is why new tokens appear around the clock.
Every token starts on a bonding curve: the price rises as people buy, and once a token raises enough liquidity it graduates to a full decentralised exchange. This guide explains how the referral pays out, how the fee works and what a bonding curve does and does not protect you from.
The campaign amounts and dates are in the change log at the end of the page, because they move. You can compare it with other deals on our crypto referral codes page.
The fine print
Arriving through the ReferralLinks link attaches the referral to your account. The fee discount applies to your trades, and the account that shared the link earns a share of the platform fee your trading generates.
The sign-up bonus and the Callout multiplier are separate campaigns with their own conditions, listed in the table below and dated in the change log.
| Benefit | What you get |
|---|---|
| Platform fee | 0.45% per trade at the last check |
| Fee discount | About 10% off the platform fee |
| Sign-up bonus | A fixed cash bonus, $50 to each side at the last check |
| Bonus condition | Deposit through Apple Pay or fiat, then place a trade |
| Callout Rewards | Referrer earns a share of the fee on referred trades |
| 4x boost | Limited-time multiplier on the referrer share |
The bonus is credited once the deposit and trade conditions are met. The bonus amount and the 4x multiplier are campaigns: the platform can change or withdraw either, so confirm them on pump.fun before you deposit.
What is pump.fun, in plain words?
Think of pump.fun as a mix between a marketplace and a social feed. New tokens appear around the clock, each with its own mini-page, live chart and comment section. Buying a token takes two clicks: you pick the amount, confirm in your wallet, and you are in.
Because everything settles on Solana, trades confirm in about a second and cost a fraction of a cent in network fees.
The bonding-curve model is what makes pump.fun different from older launchpads. Instead of an open order book at launch, the price rises in steps as more people buy, with liquidity held in the curve until the token reaches the graduation market cap and moves to PumpSwap.
The curve removes one specific rug mechanic: there is no insider allocation to dump on day one at a price the curve did not set. It does not remove the rest.
A creator can still sell into the curve right after you buy, holders can still be concentrated, and a token can still lose most of its value. Treat the curve as a pricing mechanism, not as a safety guarantee.
The deal: 10% lower fees and a $50 bonus
Arriving through the ReferralLinks link attaches the referral to your account: the reduced fee applies to your trades, and the referring account qualifies for the platform’s referral payouts.
The sign-up bonus is a separate campaign with its own conditions: a deposit through Apple Pay or a supported fiat option followed by at least one trade, as of the last check.
Read the conditions on pump.fun before you deposit, because a bonus that requires a funding method you do not use is not a bonus you will receive.
None of that changes the risk of the asset you are buying. A fee discount and a sign-up bonus are small fixed amounts; a meme coin position can lose all of its value in minutes. The bonus is worth having if you were going to trade anyway, and it is not a reason to start.
The 4x boost: how pump.fun Callout Rewards work
Callout Rewards are pump.fun’s referrer payout. Part of the platform fee from each trade is shared with the account that brought that trader in, which makes referral income proportional to how much the people you invite actually trade.
A multiplier campaign, 4x at the last check, raises that share for a limited window. The multiplier is the part that changes; the mechanism is what this section explains.
Two things about it are worth being precise about, because referral pages usually blur them. First, the multiplier applies to the referrer’s share of the fee, not to the fee the trader pays: a boost for the person who shared the link does not make the new account’s trades cheaper.
Second, a campaign that redirects platform revenue to referrers is by definition temporary: it is growth spending, and the platform sets the end date. The current multiplier and its conditions are on pump.fun, so check them there before you trade.
The platform fee and the rewards pot
pump.fun charges a platform fee on each trade, 0.45% at the last check, on top of Solana network fees and any slippage. The fee is the cost you actually pay, and it is the number the ~10% referral discount is calculated against.
Compare it with the fee on the venue you already use rather than taking a list position on trust: fee schedules change, and a comparison is only meaningful on the same day.
What happens to the fee is where the two halves of this program meet.
Part of it funds Callout Rewards and the rest is platform revenue, which is why a statement like “all revenue goes to referrers” and a statement like “revenue not paid to referrals goes into the pot” cannot both describe the same moment.
The first describes a campaign peak; the second describes the normal state. Neither is a promise about next month, and neither changes what you pay per trade.
How to claim the pump.fun referral code
Open the ReferralLinks referral link on the device where your Solana wallet lives. If you are on mobile, the link hands you straight to the app with the referral already attached. Connect a Solana wallet such as Phantom or Solflare. Creating one takes about a minute if you do not have one yet.
Deposit and place your first trade, then check the order preview before you confirm. A referral that attached correctly shows a reduced platform fee there; that preview is the only place the discount is visible before you pay it.
If the fee matches the standard rate, reopen the link and start again rather than assuming the bonus will sort it out later.
Frequently asked questions
How much is the pump.fun referral bonus?
The sign-up bonus is a campaign: $50 to each side at the last check, once the new account funds through Apple Pay or a supported fiat option and places a trade. Amounts and conditions are set by pump.fun and can be withdrawn, so confirm the current terms on the platform before you deposit.
What is the 4x boost on pump.fun?
It is a limited-time multiplier on the referrer’s share of trading fees. It does not reduce the fee the new account pays; it increases what the account that shared the link earns. When the campaign ends, the underlying referral share returns to its normal rate.
What are pump.fun Callout Rewards?
They are the mechanism that pays referrers a share of the platform fee generated by the traders they brought in. Because the payout follows trading volume, it continues for as long as those referrals keep trading, at whatever rate the platform is running at the time.
What fee does pump.fun charge?
A platform fee of 0.45% per trade at the last check, plus Solana network fees and slippage. The referral discount is calculated against that platform fee, not against your total cost, so check the fee shown in the order preview before you confirm.
Risks to know before you trade
Meme coins are highly volatile and most projects lose value quickly. Treat any position as entertainment money, never as savings, and decide your exit before you enter. Position sizing is the one risk control that actually matters here: small positions keep the game fun when a trade goes wrong.
Always verify you are on the official pump.fun domain before connecting a wallet. Fake clones of the site are the single most common way traders lose funds. Check the URL character by character, bookmark the real site, and never enter your seed phrase anywhere except the official wallet app itself.
Referral terms can change, so it is worth glancing at the current program details on pump.fun before you commit.

How to check that the Pump.fun code actually applied
Check on the platform, not on a code list. Open pump.fun from its own domain, start the sign-up (or the first deposit) and read the confirmation screen before you approve anything.
A referral that registered shows up as one of three things: a reduced fee in the order preview, a rebate line in the account, or a visible referral tag next to your address.
If none of the three is there, stop and reopen the link from this page instead of signing up and looking for a code field afterwards.
Almost every program in this list attaches the referral at registration only; a code typed later, or a page refreshed later, cannot retroactively claim an account that was created without one. This site re-tests each flow by hand and prints the date in the sidebar.
How we test codes describes what that involves.
What happens if the Pump.fun program changes or ends
Two different things end at two different times. The terms you signed up under usually keep applying to your account while the program runs, and the platform can change those terms with notice, so a rate you earned last month is not a rate you are owed next month.
When a program ends, the code field stops accepting new codes and new sign-ups stop being attributed; existing balances revert to the standard rate on the platform’s own schedule.
Commission already credited is the platform’s obligation to the person who referred you, not something this site can recover or guarantee. If a page here is out of date, it is because the change has not been re-checked yet, not because the number was invented: every figure carries the date it was last confirmed.
