A Pump.fun comment bot posts replies to a token's thread from separate wallets, so a visitor who opens the page finds a conversation instead of an empty box. On PumpWave it is the auto-comment layer of a volume session: lines in 8 languages from a rotating library, or your own .txt file, posted from distinct wallets at a density you set as a share of orders, inside the flat 1% fee.
Short version
- The reply thread is the first social signal a visitor reads. A busy chart above an empty thread looks unfinished.
- Density is set as a share of orders, so replies scale with trading instead of arriving as a fixed block.
- A language mix matches the audience Pump.fun actually has. One language repeated hundreds of times reads as a script.
- Repeated or spammy lines are the main risk: they invite moderation and turn visitors away faster than silence does.
- Favorites from distinct wallets are the quiet companion signal and cost nothing extra.
What is the reply thread on a Pump.fun token page?
Every Pump.fun token page has a thread under the chart where wallets post replies. It is part of the Pump.fun site rather than the Solana program, so a reply is not an on-chain trade and does not appear in the transaction history. Pump.fun does keep count of it: the coin data its front end loads includes a reply count and a last reply time for every token, next to the last trade time and market cap.
Pump.fun has not published how, or whether, reply activity feeds the ordering of its board. What is not in doubt is how people use the page. A visitor arrives from the board, glances at the chart, then scrolls to the thread to see whether anyone is talking about the token. That scroll is where a launch with trades and no replies loses people.
What does a comment layer do for a launch?
It closes the gap between the chart and the page. A session moves volume, trade count and distinct makers, and those show up within minutes. Without a reply layer the rest of the page stays empty, and the mismatch is obvious: hundreds of trades, nobody saying anything. With one, the thread moves at a pace that matches the tape.
It also carries the token into its next stage. After migration the token is listed on pool-level boards, and DexScreener's trending documentation counts community engagement on its own pages, visitors and reactions, alongside trading activity. A Pump.fun reply does not count there directly, but a page that has looked alive since launch is what draws people to look further. A comment layer is not a community, and the difference is set out in volume bot vs organic marketing.
Why do language mix, density and distinct wallets matter?
Four settings decide whether a thread reads as a conversation or a script.
| Setting | What it controls | Where it goes wrong |
|---|---|---|
| Density | Replies as a share of orders, from 5% to 90% in the console | Too low and the thread lags the tape; too high and nearly every trade has a reply attached |
| Language mix | English, Chinese, Korean, Japanese, Spanish, Portuguese, German and Russian | A single language across hundreds of replies reads as uniform |
| Distinct wallets | Each reply comes from a different session wallet | One address posting dozens of times reads as one person |
| Line variety | How often the same text appears | Repeats are the first thing a reader notices and the first thing moderation removes |
Density is the setting people get wrong most often. It is tempting to push it high, because more replies feels like more momentum. In practice a thread where nearly every trade has a reply attached reads as automated, while one that lags the trades reads as quiet. The console default is 40% of orders, and the presets sit between 15% and 40%. Lower suits a long, slow session; higher suits a short launch burst.
Language mix matters because Pump.fun traffic is not one market. A thread that is entirely English is not wrong, but a mix that includes Chinese, Korean or Spanish lines looks like the audience a launch actually draws. The built-in library rotates, so every session draws a different mix rather than the same lines in the same order.
Should you use the built-in library or your own lines?
The built-in library is a rotating set of 2,400 lines across 8 languages, and the console shows a random sample before you commit. It is general by design: reactions to the chart, the timing, the launch. That is enough for most sessions.
Your own lines are better when the token has something specific to say: a ticker joke, a reference to its lore, a community in-joke. Upload a plain .txt file with one reply per line, up to 5,000 lines and 512 KB. Once a file is loaded, only your lines are used and each one is posted once. The file is read inside your browser with the standard FileReader interface, which reads a file stored on your computer from inside the page, so the file itself is never uploaded to PumpWave.
- Vary the length. Mix two-word reactions with full sentences, the way a real thread does.
- Never repeat a line. Near-duplicates with one word changed read the same as duplicates.
- Leave out links and contract addresses. They are the pattern most likely to be treated as spam.
- Do not promise a price or a return, and do not claim things about the project that are not true.
- Write more lines than you need. A file twice the size of the session leaves room to drop the weak ones.
Can Pump.fun remove replies posted by a comment bot?
Yes. Pump.fun moderates content on its site and can hide or remove replies, and it does not publish a rulebook for what counts as spam in a thread. Removal is the visible cost, but the larger one is the reader: a visitor who sees the same sentence three times in a row stops trusting everything else on the page, including the chart.
The patterns that get a thread into trouble are predictable: identical lines, walls of capitals or emoji, links, repeated contract addresses and promises of returns. Avoiding them is mostly a matter of the settings above, with variety in the lines, moderate density and a different wallet behind every reply.
Why pair comments with favorites?
Favorites are the quieter half of the engagement layer. A favorite is a wallet marking the token, and unlike a reply it adds nothing to read, which is exactly why it pairs well with comments: the page gains engagement without the thread getting louder. Auto-favorites come from distinct wallets, and their density is set as a share of session wallets, from 10% to 100%.
A sensible pairing keeps favorites above comments: more wallets marking the token than talking about it, which is how organic attention usually looks. For the frequency side of the same picture, see the Pump.fun bump bot guide.
What does the comment layer cost on PumpWave?
Nothing beyond the session fee. Comments and favorites are part of the PumpWave session and sit inside the flat 1% of target volume, along with network fees, Jito tips, swap fees, token account rent and the funding of the session wallets. The minimum target is 100 SOL, so the smallest session, replies included, costs 1 SOL. Creator follows are the one optional add-on, and the console prices them before you pay.
You send only the fee, from any wallet you control. There is no seed phrase, no private key and no wallet connection. The full cost breakdown is in how much a volume bot costs, and the console itself is on the Pump.fun volume bot page. Rules on automated marketing differ by country and this is not legal advice; the safe line is never to present replies to buyers as something they are not.
Questions people actually ask
What is a Pump.fun comment bot?
A Pump.fun comment bot is a tool that posts replies to the thread on a Pump.fun token page from separate wallets. It gives the page a visible conversation that matches the trading on the chart.
Can I use my own comments?
Yes. Upload a .txt file with one reply per line, up to 5,000 lines and 512 KB. When a file is loaded, only your lines are used and each line is posted once.
Is my comment file uploaded anywhere?
No. The file is read in your browser, and the file itself is never uploaded to PumpWave.
What comment density should I use?
Start around the console default of 40% of orders for a launch burst and go lower, toward 15%, for long sessions. A thread where nearly every trade has a reply reads as automated.
Which languages does the comment library cover?
Eight: English, Chinese, Korean, Japanese, Spanish, Portuguese, German and Russian. The library rotates, so each session draws a different mix.
Can replies be removed by Pump.fun?
Yes, Pump.fun moderates its site and can hide or remove replies. Repeated lines, links and promises of returns are the patterns most likely to be removed, which is why line variety matters more than volume of replies.
