On December 5, Bubblemaps revealed the identity of the WET sniper: Ramarxyz (@ramarxyz). The individual secured 70% of HumidiFi’s token allocation during the presale by deploying over 1,000 wallets and is now seeking a refund from the project team. Per Bubblemaps, of the 1,530 addresses involved in the presale, at least 1,100 are linked to the same entity. The sniper covered its tracks by funding thousands of new wallets via a centralized exchange (CEX), with each address receiving exactly 1,000 USDC ahead of the presale. However, one address was mistakenly funded from the private wallet 547Wwc. Later, $150,000 was received from address AUG2N—also funded by 547Wwc—which is tied to the Twitter account @ramarxyz.
