Well, there are a few reasons why people choose to use bonk.fun over Pump.fun—and vice versa. That’s why we’ve decided to summarize their differences so you have a clear picture and can decide whether to launch your meme coin either platform, based on your preferences.
We summarize their differences in the following table, but it is better that you read to the end so as not to miss any detail.
| Feature | Pump.fun | Bonk.fun |

What is a launchpad?
A launchpad is a platform that facilitates the creation of meme coins and allows them to be listed so that many people can buy any coin. Quickly, these meme coinlaunchpads have evolved to what we know today: millions in daily volume and tens of thousands of users.
Recently, there has been a need to create more complete versions of the launchpads , specifically for people who trade. An example of this is Pump.fun Advanced, with more detailed information on the makers and the opportunities (as well as risks) that each currency represents.
Another feature of launchpads that a liquidity pool isn’t required for a token to token traded. On the one hand, this means that the creator cannot directly withdraw liquidity from each project, but the entire supply belongs to the launchpad, so the creator cannot conduct airdrops or offer rewards to their community as part of a strategy to promote the meme coin.
Pump.fun Vs Bonk.fun (formerly Letsbonk): main differences
Pump.fun is Solanas pioneering launchpad , while Letsbonk is a much more recent alternative. In concept, both launchpads are very similar: they facilitate the creation of meme coins and allow them to be graded at an important DEX.
From now on we will highlight the differences between Pumpfun and Letsbonk so that you can use either platform with full knowledge of which one is better for you.
Interface
The user interface is important and one of the most striking features of each launchpad. When it comes to Pumpfun Vs Bonk.fun, we can say that both platforms offer a fairly pleasant experience and are agile when displaying tokens.
Pump.fun
It has a less polished look; each meme coin an image, name, symbol, and brief description, as well as its market cap, number of comments, and information about its creation.
Bonk.fun
A "cleaner" interface with standard image sizes for each meme coin. It displays only the name, the CA, the time since creation, and the market cap in a progress bar that scales accordingly.
Graduation process
This is the key difference in this comparison between Letsbonk and Pump.fun. The reason is that when a token graduates token Pump.fun, the funds from the bonding curve are used to launch a liquidity pool on Pumpswap—Pump.fun’s own DEX—while when a token graduates token Letsbonk, the funds go to Raydium a liquidity pool.
Pump.fun
Migrates liquidity to Pumpswap, Pump.fun's own DEX, so fees are lower than in Raydium.
Bonk.fun
Throws liquidity to Raydium, the veteran DEX of the Solana ecosystem, but deducts a significant amount in fees.
Reward Fees
As for reward fees, we can confirm that Bonk.fun (formerly Letsbonk) is much better than Pumpfun. Bonk.fun charges a 0.1% transaction fee, while Pump.fun charges creators 0.05%. Furthermore, we believe Bonk.fun is the better option in this case, since a large portion of its revenue is allocated to buybacks of the launchpad main pairs, as well as investment in its token (which we’ll discuss below) and additional rewards for “trenchers” (the nickname for Letsbonk users).
For its part, Pump.fun has had to adjust to Bonk.fun's incentives, as it was attracting a lot of users. Therefore, we believe that Pump.fun will soon announce more moves involving community reward fees.
Pump.fun
0.05% of the volume of meme coins for their creators.
Bonk.fun
0.1% of volume for the creators (previously 0.05%), it also allocates 1% of its profits to buy the most outstanding pairs.
Token
In this comparison of Pump.fun Bonk.fun, we can’t overlook each launchpad token , as they have been integrated into the protocol to incentivize the use of their platforms. Although Pump.fun token Pump.fun $PUMP) is very new and its integration is limited, Bonk.fun ($LetsBONK) has made significant strides in this regard.
To start with, a portion of Letsbonk’s revenue goes toward its own token, which is then used to reward meme coin creators through the Creator Rewards program. Similarly, this launchpad integrate a points system for traders and buyers that allows them to redeem their points for $LetsBONK.
Pump.fun
$PUMP is a token new token and hasn't been fully integrated into the platform yet.
Bonk.fun
$LetsBONK is already part of the Letsbonk ecosystem and is used as an additional reward for creators and users.
Advanced mode (for traders)
Ease of creation with either platform is key, but traders also need their own interface. Pump.fun Vs Letsbonk's advanced mode tips the scales in favor of the former, as it has focused a good portion of its updates on improving the interface and functionality for traders.
Pump.fun
The advanced mode is much more complete, offering information about the holders, such as the number of snipers or bots. It also divides meme coins into newly created, about to graduate and already graduated.
Bonk.fun
The advanced mode is acceptable, as it divides meme coins into newly created, about-to-be-graduated and already graduated, but it has no key information beyond the market cap.
