Exposed: “Ramarxyz” Used 1,000+ Wallets to Snipe 70% of the $WET Presale — Then Asked for a Refund

The team has voided the entire sale and deployed a newly audited token contract to protect genuine investors and prevent similar automated exploits going forward.

A chaotic token launch on Solana has thrust decentralized finance protocol HumidiFi and Jupiter Exchange into the spotlight after blockchain analysts uncovered that a single actor orchestrated a massive botting attack on the $WET public presale, capturing the majority of tokens within seconds.

According to an in-depth on-chain report from Bubblemaps, an entity known as “Ramarxyz” used more than 1,000 wallets to seize roughly 70% of the entire presale allocation. The sale, conducted through Jupiter’s Decentralized Token Formation (DTF) launchpad, was fully sold out in just two seconds, leaving most retail buyers unable to participate.

HumidiFi Confirms Bot Attack as Evidence Points to a Single Actor

HumidiFi later acknowledged that the event was overwhelmed by a coordinated bot farm. Bubblemaps’ analysis revealed that 1,100 of the 1,530 participating addresses were controlled by the same individual.

The wallets displayed a uniform funding pattern, each receiving exactly 1,000 USDC from centralized exchanges just before the sale. One wallet broke this pattern by being funded from a private address tied to the Twitter account @ramarxyz, based on previous on-chain behavior.

Instead of denying involvement, the individual then publicly suggested that HumidiFi should refund the sniper’s allocation, despite clear evidence linking them to the exploit.

Soon after, HumidiFi announced it had voided all suspicious allocations and would compensate legitimate participants through a prorated airdrop.

Additional Analysis Reveals Further Concentration

A separate investigation by trader Gautam Mgg found that 4% of the public sale was captured by just 10 wallets, with four wallets alone accounting for 40% of the entire public sale supply, also via botting mechanisms.
