#美SEC促进加密资产创新监管框架 On-chain analysis tool Bubblemaps has recently exposed a large-scale presale sniping incident.

On December 5, a mysterious operator with the ID "Ramarxyz" was found to have used thousands of wallet addresses to grab 70% of the HumidiFi project’s WET token presale allocation. Even more dramatically, after obtaining the tokens, this person actually applied for a refund.

Here’s what happened: WET launched its presale on the Jupiter platform and sold out in just 2 seconds. Sounds like a hot sale? The reality is a bit outrageous. The Bubblemaps team discovered that, among the 1,530 addresses that participated in the rush, at least 1,100 were controlled by the same person.

This sniper’s methods were quite professional—first, they funded thousands of newly created wallets from a centralized exchange, with each wallet receiving exactly 1,000 USDC. The amounts were uniform and the timing concentrated, clearly indicating batch operations. By dispersing the source of funds in this way, they attempted to evade on-chain tracking.

However, in the end, Bubblemaps’ bubble chart analysis technology ferreted them out. This case once again proves that on-chain data is ultimately transparent, and it’s not so easy to muddy the waters.
