More than 1,000 coordinated wallets seized the sale, prompting a full restart and renewed warnings about rising Sybil threats across token launches
A major Solana presale disruption has forced HumidiFi to cancel and rebuild its WET token launch after a large-scale Sybil wallet attack overtook the sale within seconds. The incident reflects a growing pattern of coordinated wallet manipulation across presales and airdrops, raising urgent concerns for teams preparing new token distributions.
Sybil Wallet Network Snaps Up Nearly Entire WET Sale
The WET presale, hosted on the Jupiter aggregator, sold out instantly—but organizers soon determined that a bot farm used more than 1,000 wallets to capture almost the entire supply. HumidiFi confirmed the exploit and announced that it will mint a new token and issue a pro-rata airdrop to legitimate participants, with the attacker explicitly excluded. The team will hold a new public sale on Monday, citing the need for a clean and fair distribution.
HumidiFi said genuine buyers had virtually no opportunity to participate, as the coordinated wallets dominated the process.
Bubblemaps Detects Over 1,100 Identical Wallet Patterns
Blockchain analytics platform Bubblemaps analyzed the 1,530 wallets involved and found that over 1,100 displayed identical activity, including identical funding flows, synchronized timing and matching transaction sizes. The wallets were new, unfunded prior to the sale, and financed within tight time windows from shared sources.
Bubblemaps said one wallet cluster exposed a link to a user known as “Ramarxyz”, who later publicly requested a refund.
Rising Sybil Threats Across Crypto Presales
The WET event follows multiple November incidents where single entities captured disproportionate token allocations—including 60% of aPriori’s APR airdrop and 30% of EDEL tokens in another launch.
Experts warn that Sybil behavior is escalating and must be treated as a critical security threat. Analysts recommend stronger KYC checks, algorithmic detection tools, and manual participant reviews to prevent manipulated distributions.
As HumidiFi prepares its relaunch, the incident underscores the growing need for protective measures in Solana-based presales and the wider token-launch ecosystem.
