What volume a Solana volume bot generates — and what it costs per day
A volume bot buys and sells a token in small amounts from several wallets so that the chart shows steady trading. The SOL it trades is mostly recycled — the same SOL buys and then sells again — so the bot does not need its full daily volume in the wallets.
What it does consume is fees on every trade — Solana network fees and the launchpad's trading fee — plus a one-time SolBundler fee of 1% of the amount you set for Volume Maker. This calculator adds them up so you can see what a given amount of volume actually costs.
Network fees are tiny per trade. The launchpad fee is not: on the Pump.fun bonding curve every trade pays roughly 1.25%, and a bot makes many trades. That fee is usually the largest part of the cost.
Price movement adds a little more: a buy pushes the price up and the following sell brings it down, and each round trip loses a small amount to that spread.
Volume can get a coin noticed in feeds and on trackers, but it does not create demand by itself. Experienced traders look at the number of unique wallets and how trades are spaced; obvious bot patterns can work against a coin.
Use volume to support a coin that already has attention, keep trade sizes and intervals irregular, and budget it like any other marketing cost.
Only the trade size times the number of wallets, plus a small buffer per wallet — the SOL is reused for every trade. The daily cost is the fees, shown in the breakdown.
Because it is charged on every buy and every sell. A bot trading 0.03 SOL every minute from three wallets makes thousands of trades a day, and about 1.25% of each goes to the launchpad on the bonding curve.
Sometimes it helps a coin get seen, but buyers come for the coin, the narrative and the community. Volume without those rarely holds a chart up.
Fees on PumpSwap after graduation are different from the bonding curve, so treat the launchpad fee here as an estimate for coins still on the curve.
