BNB Chain posted on platform X stating that a wallet address was previously created by a former employee and was used by them to issue a token (Meme coin TST) as part of a video tutorial.The employee is no longer employed by the company due to this incident. After leaving, the employee retained unauthorized access to the relevant seed phrase and used it to generate a new private key.BNB Chain has now learned that the same address is being independently used for activities related to a new Meme token (Meme coin ASTEROID on BNB Chain).BNB Chain did not create, authorize, promote, or participate in the issuance of this token and has no control over the token or wallet address. These are unrelated to BNB Chain and have not been endorsed by BNB Chain.BNB Chain is taking legal action against the former employee and is cooperating with relevant government agencies regarding this matter.

The cross-chain protocol Axelar Network released a statement regarding the recent security incident related to Secret Network, stating that there is a misunderstanding within the community about the event. Both Axelar and the Inter-Blockchain Communication Protocol (IBC) were not attacked or compromised. The affected token smart contracts were neither developed, deployed, nor maintained by Axelar, and Axelar's firewall mechanism also prevented the impact from spreading to other chains.It is reported that the exploited contract is a forked version based on CW20-ICS20, but the developers removed two core security checks, resulting in an "infinite minting" vulnerability. By deleting the verification mechanisms originally used to prevent such issues, this fork altered the original trust model of the contract and did not undergo a new security audit.Axelar Network explained that anyone can deploy contracts for cross-chain asset wrapping through IBC, and similar contracts have also been used to wrap tokens from other chains into Secret Network. However, the Secret side fork version in this incident has vulnerabilities due to the removal of key security checks. This incident is not a unique logical flaw, nor is it an issue with the IBC protocol itself, but rather a security risk introduced by modifications to third-party contracts.

According to CoinDesk, an address from the "Satoshi era" that has never been used since March 2011, holding 35.55 bitcoins (approximately $2.54 million), made a transfer this week, which is seen as one of the first publicly visible responses from defendants in a lawsuit involving approximately 3.8 million bitcoins (valued at about $285 billion) in New York.On-chain data shows that the address transferred 15 BTC to a new address on June 2, keeping the remaining 20.55 BTC as change. The address initially received bitcoins on March 27, 2011, when the price of BTC was less than $1.In March of this year, a plaintiff using the pseudonym "Noah Doe" filed a lawsuit in New York state court alongside two LLCs from Wyoming, attempting to claim ownership of approximately 3.8 million long-dormant bitcoin wallets under New York's lost property law, positioning themselves as the "discoverer." The court approved sending on-chain notifications to the relevant wallets via the bitcoin OP_RETURN field.In July 2025, the advisory firm Salomon Brothers Strategic Advisors sent dust transactions with links to legal notices to 39,000 wallets, including the aforementioned address, requesting holders to prove ownership within 90 days.Alex Thorn, head of research at Galaxy Research, pointed out that the address corresponds to defendant number 38215 in the case, stating, "Clearly, these bitcoins have not actually been abandoned."Additionally, another address that had been dormant for 15 years, 1CDSyXAQxro4FPUoqAQb81642ruqDsUiNp, also transferred 20 BTC (approximately $1.48 million) on the same day, but this address did not appear on Noah Doe's list of lawsuits.Analysis suggests that the on-chain movements mentioned above indicate that some bitcoins from the Satoshi era, considered "abandoned assets," are actually still under the control of the original holders.

According to the Financial Times, Blue Origin, the American commercial space company founded by Jeff Bezos, is considering bringing in external investment for the first time. Introducing external capital could accelerate Blue Origin's operational expansion and technological research and development by mobilizing internal and external resources, thereby breaking through the growth model that relies solely on internal funding.More broadly, the rising interest of venture capital in the space industry may intensify competition for talent and contracts within the industry, while also sending positive signals of investor confidence to the supply chain and regulatory systems.

Bitcoin mining company and energy infrastructure platform Hut 8 announced that its subsidiary has reached a $200 million Bitcoin collateralized credit agreement with FalconX, replacing the previous financing arrangement from Coinbase Credit. The new financing has an annual fixed interest rate of 7.0%, a decrease of 200 basis points from the previous 9.0% financing from Coinbase; during the period from December 2023 to March 2025, the financing cost was as high as 10.5%–11.5%, with a cumulative reduction of up to 450 basis points, demonstrating progress in continuously optimizing debt costs.After this refinancing, Hut 8 has approximately 3,300 BTC converted to an uncollateralized state, valued at about $260 million based on the market value as of May 1, 2026, significantly enhancing its balance sheet flexibility and liquidity. Meanwhile, the credit structure maintains key risk control terms, including a limited recourse structure, a no-rehypothecation clause, and a fixed LTV threshold design, preventing additional margin calls triggered by a decline in Bitcoin prices.Hut 8's management stated that this financing not only reduces financing costs but also releases more uncollateralized Bitcoin assets, helping to enhance capital allocation flexibility across different market cycles; FalconX emphasized that this transaction reflects its ongoing expansion capabilities in institutional-level Bitcoin credit solutions.

Syndicate has released an update regarding the recent security incident, stating that the leakage of private keys led to the malicious upgrade of bridging contracts on two chains, resulting in the theft of approximately 18.5 million SYND (about $330,000) and around $50,000 in customer tokens. Affected users will receive full compensation, and SYND holders will receive additional compensation.The attack involved multi-stage reconnaissance, infrastructure mapping, vulnerability exploitation development, and precise timing, ruling out the possibility of insider involvement. The root cause of the vulnerability was the storage of private keys in a password manager, and the upgrade process did not utilize multi-signature or hardware signing. Syndicate is strengthening security measures, including adding an encryption layer outside the password manager and implementing multi-signature or hardware signing for the upgrade path.

SpaceX announced today that it has reached a cooperation intention with AI programming startup Cursor, which grants SpaceX the right to acquire it later this year for $60 billion, or to pay $10 billion to advance the cooperation between the two parties.It is reported that Cursor's developer Anysphere completed a $400,000 Pre-Seed round of financing in April 2022, jointly invested by Alameda Research and Heroic Ventures. Among them, Alameda invested $200,000 in Anysphere, acquiring about 5% of the shares.This equity was sold at the original price during the bankruptcy liquidation of FTX.

The blockchain interoperability protocol Hyperbridge disclosed details of the previous DOT attack incident, resulting in a loss of approximately $237,000. The root of the vulnerability lies in the HandlerV1 contract's VerifyProof() function, which lacks input validation and does not verify the leaf_index leafCount, allowing attackers to forge Merkle proofs.Using this, the attacker gained administrator privileges for the DOT token bridging contract on Ethereum, subsequently minting 1 billion bridged DOT (which is about 2800 times the legitimate circulation of approximately 356,000) and cashing out on decentralized exchanges. Hyperbridge stated that it is currently working with security partners to trace the funds, and cross-chain functionality will remain suspended until the investigation is completed.

Binance founder Zhao Changpeng (CZ) recalled in his new book that he was approached in early 2014 to become the CEO of Mt. Gox's China region.

Gox to handle technology, and CZ to manage operations in China, with an approximate 10% equity stake.CZ stated that he subsequently met with Mt. Gox founder Mark Karpeles in Tokyo, but just as both parties were close to signing, Mt. Gox suddenly suspended withdrawals on February 7, 2014, leading to a crisis, and he ultimately decided not to join.
