A small group of crypto wallets won more than $1.2 million betting on a Polymarket contract tied to an onchain investigation into decentralized finance (DeFi) trading platform Axiom, fueling fresh concerns that prediction markets can reward people with advance knowledge of market-moving disclosures. The eight most profitable wallets on the market collectively made about $1.2 million, according to trading data compiled on Dune. The same dataset showed more than 50 wallets posting combined losses of roughly $1.23 million, while two wallets lost about $366,000. Eight out of the top 10 wallets are likely insider addresses, judging by their onchain transaction patterns, according to onchain researcher Defioasis. “There are 3 addresses that achieved profits exceeding $100,000, all of which are insider addresses that traded only this single mark...

The incident is potentially related to December's Trust Wallet hack, which left users drained of $7 million in cryptocurrency. An attacker has drained "hundreds” of crypto wallets on Ethereum Virtual Machine (EVM) chains, siphoning small sums from each victim in what onchain investigator ZachXBT described as a broad but low-value exploit. The losses appear limited on a per-wallet basis, with each victim losing less than $2,000, according to ZachXBT. The activity has affected wallets on several EVM-compatible networks, indicating a widespread incident rather than isolated to a single blockchain. A fraudulent email disguised as legitimate communication from Web3 wallet MetaMask could have been the vehicle for the attack, said cybersecurity researcher Vladimir S., who cited a clue left by another pseudonymous X user.

UFC star Conor McGregor criticized former rival Khabib Nurmagomedov for his non-fungible token (NFT) drop on Telegram, which featured digital “papakhas” — a traditional hat worn in Nurmagomedov’s native country of Dagestan.  “There is just no way good guy Khabib used his late father’s name, as well as Dagestan’s culture, to scam his fans and fire sell a bunch of digital NFTs online,” McGregor wrote in a now-deleted X post.  Onchain sleuth ZachXBT responded to McGregor, pointing out that McGregor attempted to launch his own celebrity memecoin in April called REAL.

Crypto users must deal with costly fees, protocol-level restrictions and multiple service providers to execute simple stablecoin transactions. The number of different stablecoin tickers and token standards is fragmenting liquidity across the crypto ecosystem and burdening users with a poor experience that is costly, technical,and time-consuming, according to onchain sleuth ZachXBT. Cross-chain bridging restrictions, gas and transaction fees that must be paid in the native token of the blockchain being used, and a lack of universal token support across exchanges are all obstacles users face in transferring stablecoins across the crypto ecosystem, ZachXBT said. He gave the following example: From there, the user may realize that their exchange of choice doesn’t support the token or a swap on that token and is forced to bridge to a different blockchain, spend more on gas fees, download another wallet or sign up for another exchange to execute the transaction.

ZachXBT claims over 80% of Garden Finance’s fees are tied to crypto laundering, challenging the project’s decentralization narrative. Blockchain sleuth ZachXBT has accused Garden Finance, which brands itself as “the fastest Bitcoin bridge,” of facilitating the laundering of funds linked to major crypto thefts, including the Bybit hack.

The allegation came in response to an earlier post by Jaz Gulati, a co-founder of Garden Finance, who had recently touted the platform’s success, citing 38.86 Bitcoin (BTC) in collected fees — $300,000 of which was earned over the 12 days ending June 2.

ZachXBT says both the wallet addresses that sent Silk Road founder Ross Ulbricht 300 Bitcoin were active in 2014 and 2019 while he was in prison. Ross Ulbricht’s recent receipt of 300 Bitcoin is from “questionable sources,” but it’s unlikely to be a case where he donated it to himself, says blockchain researcher ZachXBT. Ulbricht, who founded the infamous online black market Silk Road, received 300 Bitcoin (BTC), worth $31.4 million, to his wallet that was soliciting donations, Blockchain analytics firm Lookonchain said in a June 1 post to X. The funds came from wallets using a centralized mixing service called Jambler, which led some social media users to speculate, without evidence, that the funds could be Ulbricht’s profits from the Silk Road, which he might have hidden away before he was nabbed by authorities and sent to prison.
