# The rug problem of Pump.fun coins

In solana network, developers can use multiple wallets to secretly buy large amounts of tokens, and all the buys are then executed in separate transactions but within the same block. Afterward, they can instantly sell all of them, causing the token price to crash. 95% of the projects on pump.fun are such scam projects. pump.fun's UI does not display these scam behaviors effectively. For example, in this coin, someone bought 84.95 SOL using 15 separate wallets at block 309676118. pump.fun's UI does not display this information.

# aiyc's Part

Very simply put, we just grab all the transactions for every pump.fun coin and re-display them in a nice and comprehensive format. We also quickly scan the holders of the token to check if the wallets involved in a batch buys are still holding or not, and how much they're holding.

We tell you each block, how many unique wallets bought in that block, how much SOL they've spent, and how much they're still holding. This data is once again derived from the pump.fun transactions directly and we don't bring anything from our side. We just make it easier to check because otherwise it would require a LOT of digging. That's not ideal for the quick-pace of these tokens.

# ⚠️ Considerations

Our tool is by no means perfect. It's a simple transaction block viewer, and you have to understand that two UNRELATED wallets could sometimes purchase in the same block. This would happen if someone has two wallets loaded on something like BullX (they have multi-wallet buys), or someone with a very fast copytrading bot. If a token also has a lot of eyes on it and a lot of people are trying to buy it, two transactions can be processed in the same block.

Generally speaking, don't pay too much attention to block bundle buys that now are holding a low amount %. You should mostly be looking for something that are holding larger amounts of supply. Those will never happen by chance.

An easy red flag is if a token scan looks like this:

You can see 15 wallets bought in a single block, and are now holding 55% of the supply. That is an extremely deliberate bundle buys and will most likely go to 0 within a few minutes.

Some "bad" bundle buys could have multiple 5-wallet bundles, or some 10-15 wallet bundles, etc. If you see a bunch of random 2 wallet ones that are far apart, this is likely a false positive.
