Is there a free Pump.fun volume bot?
Why free volume bots exist, what the chain charges regardless of who pays, what the open-source route involves, and how free offers earn.
People search for this constantly and the answer is more interesting than a flat no.
Free bots do exist. Free volume doesn't, and the gap between those two facts is where your money goes.
The costs the chain charges regardless
Four things get paid before a single swap lands on your mint, and Solana sets all of them.
Network fees on every transaction. Priority fees whenever the chain is busy enough to matter. Rent and funding for every wallet in the fleet, including the token account each one opens. Bundling tips, if the trades are protected from sandwiching.
None of that cares whether the software was free. A campaign producing 400 swaps pays 400 network fees whoever wrote the code. What a campaign actually costs breaks the components apart properly.
So what can "free volume bot" possibly mean? Free software, and nothing more. The chain still invoices you.
What the free offers actually are
Three categories, and it's worth knowing which one you're looking at.
Open-source scripts. Real code, genuinely free, on GitHub. You supply the SOL, the wallets and the operational judgement. More on that below.
Free trials. A small amount of activity at no charge to demonstrate the service. Legitimate marketing, and the trial is usually too small to tell you much.
Free that isn't. Something advertised as free that asks for a wallet connection, a seed phrase, an approval, or an upfront "gas deposit" you send to an address. That last one is the most common scam shape in this category, and the deposit never comes back.
If anything calling itself free wants a key or a standing approval, the product is your wallet. There's no version of a volume campaign that needs either, which how to judge a volume service covers as the first filter.
The open-source route, honestly
Running a free script yourself is a real option. Let's be accurate about what it involves.
The trading loop is easy. Buy, sell, repeat, on a timer. An afternoon of work, and it produces a tape that any trader spots instantly because everything about it repeats.
What separates that from a campaign worth running:
- Fleet width. Hundreds of funded wallets, each with its own history and cadence, rather than 5 addresses taking turns
- Funding pattern. One address sending equal amounts to 200 wallets in a burst is a readable graph, and anybody can read it
- Irregular timing. Gaps drawn from a distribution, because even spacing is a fingerprint
- Varied sizes. A tape repeating 0.4 SOL forty times is not a crowd
- MEV protection. Without bundling, searchers take a cut of every leg you send
- Adaptive fees. Fixed priority fees stall exactly when the network is busy, which is when attention peaks
- Migration handling. Routing changes when your coin graduates to PumpSwap
Get one of those wrong and the rest stops helping. How a fleet gets funded covers the part that looks simplest and isn't.
The arithmetic of doing it yourself
Say you want 200 SOL of volume across 800 wallets over 12 hours.
You need SOL to fund 800 wallets, rent for 800 token accounts, network and priority fees for however many thousand swaps that produces, and either bundling tips or acceptance that searchers take a slice. Then you need to build and operate the timing, sizing and routing logic.
The software being free saves you the software. It doesn't save you the SOL, and it doesn't save you the two weeks of getting the pattern right.
For comparison, Curvegrad charges 2% of target volume with all four cost components inside it, so that 200 SOL campaign costs 4 SOL. Whether that's better than doing it yourself depends entirely on what your time is worth and whether you enjoy debugging funding graphs.
The version that's genuinely cheap
If budget is the constraint, the honest answer isn't a free bot. It's a small real campaign.
Our minimum is 50 SOL of target volume, which costs 1 SOL. That's the point below which fixed costs start dominating and the activity gets too thin to register on any ranking surface, which makes spending less actively worse value than spending nothing.
Whatever you choose, verify the output. Open your mint in an explorer and look for swaps from many distinct wallets across the claimed window. How to use Solscan covers exactly what to check, and it works the same whether you paid nothing or paid somebody.

Frequently asked
Free software exists. Free volume does not, because every swap costs a network fee and every wallet needs funding. Somebody pays those, and if it is not you, ask what they are getting instead.
Yes, and the code is the easy part. Funding a fleet without leaving an obvious pattern, handling priority fees and avoiding sandwiches is where the actual work lives.
Running the smallest real campaign you can. Below a certain size the fixed costs dominate and you get activity too thin to register, which is worse value than not spending at all.
Everything in this guide describes mechanics that settle on Solana mainnet, so you can check any of it yourself. Mint addresses, swap signatures, curve progress and wallet counts are all public, and an explorer will disagree with us if we are wrong.
Curvegrad sells a volume service, and guides that touch on what a campaign does say so in the text rather than in a footnote.
