Pump.fun vs bonk.fun (formerly Letsbonk): Key Differences and Which One to Pick
If you’re looking for a launchpad in the Solana ecosystem, it makes sense to run a comparison of Pump.fun vs bonk.fun (formerly Letsbonk). After all, both are among the most widely used launchpads at the time of writing.
There are real reasons why some people choose bonk.fun over Pump.fun, and vice versa. That’s why we’ve laid out the key differences to give you a clear picture and help you decide which platform to launch your meme coin on, based on base and your own preferences.
Here’s a quick summary of the differences in the table below, but read all the way through so you don’t miss any details.
| Característica | Pump.fun | Bonk.fun |
|---|---|---|
| Interfaz | Sin pulir, pero con más información | Mucho más limpia, pero con información justa |
| Proceso de graduación | Lanzamiento de liquidity pool en Pumpswap (DEX propia con menos fees) | Mueve la liquidez a Raydium (DEX veterana, pero con más fees) |
| Recompensas | 0.05% de volumen para los creadores | 0.1% de volumen para creadores (+0.05%) |
| Token del ecosistema | $PUMP, lanzada el 14 de julio de 2025 y con enorme liquidez (a la espera de integraciones) | $LetsBONK, lanzada en abril del 2025, ya integrada y con una liquidez grande |
| Modo Avanzado | Con información muy completa, perfecto para traders de meme coins | Aceptable, pero no es tan competente como el de Pump.fun |
What Is a launchpad?
A launchpad is a platform that makes meme coin creation straightforward and lists tokens so anyone can buy in. These meme coin launchpads have grown fast into what we see today: millions in daily volume and tens of thousands of active users.
More recently, there’s been a push to build more full-featured versions of these launchpads, specifically for active traders. Pump.fun Advanced is one example, offering deeper data on makers along with the opportunities and risks each token presents.
Another key aspect of launchpads is that a liquidity pool isn’t required for a token to be traded. On one hand, this means the project’s liquidity can’t be pulled directly by the creator; on the other, the entire supply belongs to the launchpad, so the creator can’t do airdrops or reward their community as part of a strategy to grow meme coin.
Pump.fun vs Bonk.fun (formerly Letsbonk): Main Differences
Pump.fun is the original launchpad on Solana, while Letsbonk is a much more recent alternative. Conceptually, both launchpads work the same way: they simplify meme coin creation and allow tokens to graduate to a major DEX.
From here, we’ll walk through the differences between Pump.fun and Letsbonk so you can choose either platform with a full understanding of which one works best for you.
Interface
User interface matters, and it’s one of the first things you notice about any launchpad. When it comes to Pump.fun vs Bonk.fun, both platforms deliver a smooth experience and make browsing tokens feel effortless.
Pump.fun
The aesthetic is rougher overall; each meme coin displays an image, name, symbol, and short description, along with the market cap, comment count, and creation details.
Bonk.fun
Cleaner layout with standardized image sizes for each meme coin. It only shows the name, CA, time since creation, and market cap on a progress bar tracking graduation status.
Graduation Process
This is the biggest differentiator in the Letsbonk vs Pump.fun comparison. When you graduate a token on Pump.fun, the bonding curve funds are used to launch a liquidity pool on Pumpswap, Pump.fun’s own DEX, whereas graduating a token on Letsbonk routes those funds into Raydium as a liquidity pool.
Pump.fun
Liquidity migrates to Pumpswap, Pump.fun’s native DEX, so fees are noticeably lower than on Raydium.
Bonk.fun
Liquidity launches into Raydium, the battle-tested DEX in the Solana ecosystem, but it takes a significant cut in fees.
Reward Fees
On the rewards fee front, Bonk.fun (formerly Letsbonk) has a clear edge over Pumpfun. Bonk.fun charges a 0.1% transaction fee, with 0.05% going to Pump.fun creators. What makes Bonk.fun the stronger option here is where that revenue actually goes: a significant share funds buybacks of the top launchpad pairs, investment into its ecosystem token (more on that below), and extra rewards for trenchers (the nickname for Letsbonk users).
Pump.fun has had to adapt to Bonk.fun’s incentive model, as Bonk.fun was pulling in a growing share of users. At this pace, it won’t be long before Pump.fun announces more moves around community reward fees.
Pump.fun
0.05% of meme coin volume goes to creators.
Bonk.fun
0.1% of volume for creators (up from 0.05%), plus 1% of revenue allocated to buying back top pairs.
Ecosystem Token
In this Pump.fun vs. Bonk.fun comparison, each platform’s native token is worth a closer look, since both have been integrated into the protocol to drive platform usage. Pump.fun’s token ($PUMP) is still brand new with limited integration, but Bonk.fun ($LetsBONK) has made real progress on this front.
For starters, a portion of Letsbonk’s revenue flows into its own token, which is then used to reward meme coin creators through Creator Rewards. The launchpad also plans to roll out a points system for traders and buyers, letting them redeem those points for $LetsBONK.
Pump.fun
$PUMP is a very recent token and hasn’t fully integrated into the platform yet.
Bonk.fun
$LetsBONK is already embedded in the Letsbonk ecosystem and serves as an additional reward for creators and users.
Advanced Mode (for Traders)
Ease of creation is solid on both platforms, but traders need a dedicated interface too. When it comes to advanced mode, Pump.fun vs Letsbonk isn’t a close call: Pump.fun has put a significant share of its updates into sharpening the trader-facing UI and expanding its feature set.
Pump.fun
Advanced mode is far more comprehensive. It gives you holder insights like sniper and bot counts, and breaks meme coins down into three categories: newly created, about to graduate, and already graduated.
Bonk.fun
The advanced mode is decent: it splits meme coins into newly created, about to graduate, and already graduated, but it’s missing key data beyond the market cap.
Pump.fun or Bonk.fun? Where You Should Launch Your meme coin
Now that you know the core differences between Pump.fun and Bonk.fun, it’s time to pick a platform. You’re free to use both and run your own tests. That said, one may serve you better than the other, in base to these needs:
- Want to maximize your earnings as a creator? Go with Bonk.fun; it rewards you in SOL and its own token.
- Looking to buy coins? Use Pump.fun with its Advanced feature.
- Concerned about DEX fees after your token graduates? Pump.fun is the better alternative.
- Chasing new trends? Bonk.fun is gaining momentum fast, and the rewards for getting in early can be well worth it.
Both launchpads are making their mark in Solana’s meme coin ecosystem, and either is a solid option. Based on your base to the questions above, you can choose the platform that best fits your goals.
