Bot Attack Results in Ramarxyz Sniping 70% of HumidiFi $WET Presale on Jupiter DTF
HumidiFi's $WET public presale, held on Jupiter's Decentralized Token Formation (DTF) platform, was targeted by a mass bot attack that saw a significant portion of the tokens captured by a single actor known as "Ramarxyz." Investigations revealed that over 1,100 of the 1,530 participating addresses were controlled by this actor, who used about 1,000 USDC per wallet to secure roughly 70% of the public presale through automated bot activity.
The public sale, which offered 30 million $WET tokens at $0.069 with a per-wallet cap of 1,000 USDC, raised a total of $5.57 million from the Wetlist, JUP stakers, and the general public. The sale sold out in approximately two seconds. On-chain analysis revealed that 4% of the public allocation was claimed by just 10 wallets, with four wallets alone accounting for 40% of the public sale via bot mechanism. Jupiter Exchange faced criticism for its lack of basic bot protections, renewing concerns about the fairness of token distribution on launchpads.
Following the incident, HumidiFi announced it has canceled the suspicious bot allocations and will issue a prorated airdrop to legitimate participants under a newly deployed audited token contract. Plans for a new public sale have also been announced. HumidiFi, launched in mid-2025 on the Solana blockchain, uses $WET tokens for staking and rebates. The project intends to follow up with token reissues and future liquidity-pool launches.
This attack echoes an earlier September Sybil attack on MYX and puts a spotlight on Jupiter DTF, which is promoted as a transparent launch method but has not provided a detailed technical breakdown by Jupiter or other involved parties. HumidiFi's activity is contextualized by Solana DEX volume metrics, showing ongoing ecosystem engagement despite launchpad challenges.
