A pump.fun bump bot repeatedly buys a very small amount of a coin, often 0.005 to 0.03 SOL, so the coin keeps reappearing at the top of views sorted by latest trade. Rates of 2 to 20 bumps a minute cover most situations, and bumps read best from many rotating wallets with varied sizes and timing.
Key points
- Bumping buys visibility in recency-sorted lists. It adds very little volume and almost no curve progress.
- A self-run bump pays a trading fee, a 0.000005 SOL base fee and whatever priority fee you set, plus token account rent on new wallets.
- Thousands of bumps add up: a three-hour session at 10 a minute is 1,800 transactions to fund and sign.
- Our console offers an optional bump layer from 2 to 20 per minute, sent from the run wallets, with every fee inside the flat 1% charge.
- Bumps blend in best when they come from many wallets, in varied sizes, at uneven intervals.
On a script you run yourself, each bump pays the Pump.fun trading fee, a Solana base fee and usually a priority fee. Inside one of our runs those costs are already part of the flat 1% of the volume goal.
What does a pump.fun bump bot actually do?
A pump.fun bump bot is a script that buys a tiny amount of a coin on a loop, so the coin jumps back to the top of views sorted by latest trade. Some Pump.fun views order coins by how recently they traded, and any buy, however small, moves a coin back to the top until the next coin trades. The bot just automates that: a loop that signs a tiny buy every few seconds, sometimes followed by a sell of the same tokens so the wallet doesn't slowly fill up with dust.
It's a placement tool. Nothing more.
People confuse bumping with volume all the time, and the confusion costs them money. If you want the 24-hour volume figure to grow, or the holder count, or the number of distinct traders, bumping barely touches any of it. Ten thousand bumps of 0.01 SOL is 100 SOL of buys, which sounds big until you notice it took ten thousand transactions to get there and every one of them came from the same handful of addresses.
How much does each bump cost?
The cost of a bump depends on who sends it. A bump you script yourself pays Pump.fun's trading fee on the buy, at whatever rate the official fee page shows that day, and pays it again on the sell if you sell back. On top of that sits Solana's base fee of 5,000 lamports per signature, which is 0.000005 SOL, and a priority fee if you set a compute unit price. Most bump scripts do set one, because a bump that lands thirty seconds late is pointless.
| Cost item | Self-run bump script | Bump layer in our run |
|---|---|---|
| Pump.fun trading fee | Paid by your wallet on every buy and sell | Inside the flat fee |
| Base network fee | 0.000005 SOL per signature | Inside the flat fee |
| Priority fee | Your choice, per transaction | Inside the flat fee |
| Jito tips | Your choice, if you bundle | Inside the flat fee |
| Token account rent | About 0.002 SOL per new wallet, returned on close | Handled by the run |
What does a three-hour bump session add up to?
A three-hour bump session at 10 bumps a minute is 1,800 transactions, each one funded and signed. With 0.02 SOL buys and no sell-back, the wallet has spent 36 SOL on tokens it now holds, plus a fee on every one of those 1,800 trades and 1,800 sets of network fees. Sell each one back and the token spend mostly returns, but the fee line roughly doubles, and every round trip loses a little to the curve's price movement between the buy and the sell.
There's one more cost people forget. The first time a wallet buys a token, Solana creates an associated token account for it, and that account locks a rent deposit of roughly 0.002 SOL. You get it back only if the account is closed later. Rotate through 200 bump wallets and that's around 0.4 SOL parked in rent until you clean up.
Do bump costs change after graduation?
Yes, bump costs change after graduation for a self-run script. After graduation the coin trades in the canonical PumpSwap pool, which has its own fee schedule, so a self-run script's costs shift mid-session. Inside one of our runs nothing shifts: trade fees on curve or pool, network charges and Jito tips all belong to the flat 1% of the volume goal, so no extra bill reaches the creator. The Pump.fun volume bot price page works through that fee at five run sizes.
What bump rate should you pick?
A sensible bump rate is 2 to 20 bumps a minute, picked by how fast the feed is moving. Pump.fun hasn't documented the ranking or refresh logic behind its feeds, so any exact rate is a judgment call. We can describe how the trade-off behaves, though. A bump only keeps you on top until another coin trades. When the platform is quiet, that might be twenty or thirty seconds. When it's busy, it can be a couple of seconds, and no sane bump rate will hold the spot.
So the question isn't how to stay on top permanently. It's how often you want a fresh chance at a glance from someone scrolling.
| Situation | Rate in our console | Reasoning |
|---|---|---|
| Slow hours, small coin | 2 to 4 per minute | Feed moves slowly, so each bump stays visible longer |
| Ordinary trading hours | 5 to 10 per minute | Enough to resurface regularly without flooding the trades tab |
| First hour after launch | 10 to 20 per minute | Short window when attention is highest and competition is heavy |
| Coin already busy with real buyers | 0 to 2 per minute | Organic trades already bump the coin; extra bumps only add noise |
Why do more than 20 bumps a minute backfire?
Above 20 a minute, in our runs, the extra bumps mostly bury real trades in the activity list. A visitor opens the coin, sees a wall of 0.01 SOL buys, and can't find a single normal-sized order. That's worse than fewer bumps.
Time of day matters too. Solana activity swings with the US and Asian sessions, so a rate that felt right at noon UTC can look frantic at 03:00. We usually suggest picking one rate per run rather than chasing the feed minute by minute, then reviewing it after the first half hour.
Why do rotating wallets read better than one?
Rotating wallets read better than one because buyers judge a coin by who is trading it. Picture the trades tab from a buyer's side. The same short address appears forty times in a row, buying 0.02 SOL every six seconds, never selling, never varying the size. Would you buy? Plenty of Pump.fun traders would scroll past, because a column like that doesn't look like a crowd. It looks like one person with a timer.
Three things make a bump column look repetitive: one address, one size, one interval. Changing only one of those three doesn't help much. A single wallet with random sizes still looks like one wallet, and a hundred wallets buying identical amounts on the same beat still look like a metronome.
How does our bump layer rotate wallets?
That's why our bump layer doesn't run as a separate bot. When you switch it on inside one of our multi-wallet volume runs, each bump is sent by one of the run's own fresh wallets, the same wallets that place normal-sized buys and sells during the session. Sizes vary, timing varies, and the bumps sit among real-sized orders instead of forming their own column.
Every one of those bumps is a normal on-chain swap that settles like any other trade, and you can open each one on Solscan. The aim is simple: the coin page should read like many independent traders are active on it, which is what a buyer scrolling past wants to see.
How do bumps differ from volume and holders?
Bumps, volume and holders are three separate signals, and each tool moves a different number on the page. Bumps move recency. Volume runs move the volume and trader counts and the chart. Holders are a third number, shaped by how many wallets keep a balance once trading stops; the Pump.fun holder bot page splits them into dust and retained holders. Replies in the coin's thread are a fourth signal, and the Pump.fun comment bot guide explains how many is too many.
| Signal on the page | Bumps alone | Volume run with bumps on |
|---|---|---|
| Position in recency views | Rises briefly, often | Rises briefly, often |
| Volume figure | Tiny | Your target, from 100 SOL |
| Distinct traders | One or a few | 500 to 10,000 fresh wallets |
| Chart shape | Flat with noise | Moves with two-sided orders |
| Trades tab | Repeated identical buys | Mixed sizes from different addresses |
How do you set a bump rate in our console?
Paste the mint
The mint is the coin contract address, so drop it into the console. The console reads the mint and tells you whether the coin trades on the bonding curve right now or has moved to its PumpSwap pool. That matters, because the run sends every buy, sell and bump to the right venue. The check takes a few seconds.
Size the run
The run size is three numbers: the target volume (minimum 100 SOL), the number of fresh wallets between 500 and 10,000, and a pace between 15 minutes and 10 hours. More wallets spread the bumps thinner, so each address shows up only a few times. A longer pace keeps the whole session calmer.
Turn on feed bumps
Set a rate from 2 to 20 per minute. Start at 2 to 4 for a long run during slow hours and use 5 to 10 for ordinary trading hours. Go up to 10 to 20 only for the short window right after launch, when attention on the feed is highest.
Pay the deposit address
Send the 1% fee in SOL to the deposit address on screen; a Solana Pay QR code works too. You never connect a wallet, share a key or sign anything for us. On a 100 SOL target the fee is 1 SOL, shown before you pay.
Watch the trades tab
The trades tab is where a bump rate proves itself. Check how the activity list reads after ten minutes. A healthy trades tab shows bumps mixed in among normal-sized orders from different addresses. If a wall of 0.01 SOL buys crowds out the normal orders, ask support to lower the rate, then review it again after the first half hour.
When should you skip bumping?
Skip bumping when the coin page is empty, when real buyers are already active, or when the goal is graduation. An empty page means bumping sends people to nothing. No replies, a flat line, a dozen holders and a creator who's gone quiet. Fix that first. Bumping is also wasted once real buyers are active, since their trades resurface the coin on their own. And it doesn't count toward graduation in any meaningful way: working from the constants Pump.fun publishes for its curve, our own arithmetic puts the requirement at about 85 SOL of net buying to finish the curve, and bumps that get sold back contribute close to zero of it.
One more thing. Rules on token promotion differ from country to country. We aren't lawyers and none of this is legal advice. When in doubt, look up the local position before a run starts.
Quick answers
What does a pump.fun bump bot do, in one line?
A pump.fun bump bot is a script or service that sends very small buys of a coin, often 0.005 to 0.03 SOL, on a loop. The coin then keeps showing up at the top of Pump.fun views sorted by most recent trade. A bump bot adds visibility in those feeds, not meaningful volume, holders or curve progress.
How much does one bump cost?
One bump on a self-run script pays the Pump.fun trading fee, a 0.000005 SOL base fee per signature as listed in the Solana fee docs, and whatever priority fee you set. A sell-back pays the same set again. Inside one of our runs the bump layer adds nothing, because those costs sit inside the flat 1% fee.
Is 20 bumps per minute too many?
Yes, 20 bumps per minute is too many for most coins outside the first hour after launch. At that rate tiny buys flood the trades tab and hide normal orders. Our console allows 2 to 20 bumps a minute. We suggest 5 to 10 for ordinary trading hours and 2 to 4 for slow hours or long runs.
Why bump from many wallets instead of one?
Bumping from many wallets is the better choice, because bumps from many wallets read like a crowd of independent traders, and bumps from one wallet read like a timer. A trades tab where one address buys the same 0.02 SOL every six seconds looks like a single person. Our bump layer sends each bump from one of the run's 500 to 10,000 fresh wallets, with uneven sizes and gaps.
Does bumping help a coin graduate?
Bumping barely helps a coin graduate, because graduation depends on net SOL entering the bonding curve. Working from the curve constants in the Pump.fun docs, our arithmetic puts the requirement at about 85 SOL of net buying. Bumps of 0.005 to 0.03 SOL are tiny, and bumps that get sold back add almost nothing net.
Are bumps included in the run fee?
Yes, bumps are included in the run fee. The bump layer is optional and adds no separate charge. One flat 1% charge on the target volume, from a 100 SOL minimum, pays for the entire run. That covers the Pump.fun trading fee on every bump and the priority fees or Jito tips our wallets send.
Keep the coin near the top
Set a bump pace and a wallet count, and the run spreads small buys across rotating wallets. Your 1% fee is shown in SOL before you pay anything.
