Stablear EURR and USDR Depeg Following Multisig Wallet Exploit

According to Wu Blockchain, stablecoin issuer Stablear, which is backed by Tether and Kraken, saw its EURR and USDR lose their peg after a multisig wallet exploit.

The Block reported that the attacker exploited a vulnerability in a 1-of-3 multisig wallet to mint $13.5 million worth of unbacked tokens. The incident has once again underscored concerns over stablecoin reserve credibility and issuance authority management.

Iran Military Adviser Warns of “Harsh and Unprecedented Response” Over Strait of Hormuz

According to Odaily, Mohsen Rezaei, a military adviser to Iran’s supreme leader, said hostile forces entering the Strait of Hormuz and the Persian Gulf would face a “harsh and unprecedented” response.

Rezaei said Iran could begin retaliatory measures by breaking a maritime blockade, adding that if the current situation continues, one of Iran’s strategic options could be withdrawing from the Nuclear Non-Proliferation Treaty.

Representatives of Iran’s supreme leader argued that managing the Strait of Hormuz is a legitimate right tied to national security. The Strait of Hormuz is a vital route for Middle Eastern oil shipments, and any escalation there could affect global oil prices and sentiment toward risk assets.

Trump: “Full Maritime Blockade Will Remain Until Agreement Is Certified and Signed”

President Trump said negotiations are proceeding in an orderly and constructive manner and instructed representatives not to rush into an agreement.

He added that the maritime blockade would remain fully in place until an agreement is reached, certified, and signed. The remarks are being interpreted as a factor that could heighten geopolitical uncertainty as related negotiations continue.

U.S. Official: “Iran’s Supreme Leader Has Approved the Overall Framework of the Deal”

Odaily, citing Axios, reported that a U.S. official said Iran’s supreme leader has approved the overall framework of the agreement.

The official added that important wording and expressions still remain to be resolved between the U.S. and Iran, and that the agreement is unlikely to be signed on Sunday.

With some key issues and Iran’s internal approval procedures still pending, finalization is expected to take several more days.

Crypto Futures Liquidations Reach $382 Million in the Past 24 Hours

According to CoinAnk data, total liquidations across the cryptocurrency futures market reached $382 million over the past 24 hours.

Of that total, $132 million came from long liquidations and $250 million from short liquidations. Bitcoin liquidations totaled $134 million, while Ethereum liquidations came in at $86.1775 million.

BitMine’s Book Loss on ETH Holdings Expands to About $7.35 Billion

According to Odaily, as Ethereum weakness continues, the book loss on BitMine’s ETH holdings under Tom Lee has expanded to about $7.35 billion.

BitMine began its ETH treasury strategy in July 2025 and has continued accumulating since then. It currently holds about 5.28 million ETH, equivalent to roughly 4.37% of Ethereum’s total supply.

Analysts noted that ETH is currently near the lower support line of a bearish rising wedge pattern, and if that support breaks decisively, it could fall further into the $1,600 range.

In that case, based on BitMine’s average purchase price of about $3,513, the unrealized loss on its ETH holdings could widen to around $10.1 billion.

According to Santiment data, the ratio of bullish to bearish mentions of ETH on social media has also fallen from more than 2:1 in late April to around 1:1 recently, indicating continued deterioration in investor sentiment.

200 Million USDT Transferred From Bitfinex to Tether Treasury

According to Whale Alert, 200 million USDT, worth about $199.75 million, was transferred from Bitfinex to the Tether Treasury.

The transaction was confirmed on the Tron network. Transfers to the Tether Treasury may be related to issuance, redemption, or liquidity adjustments, though the specific purpose has not been confirmed.

Vitalik: “The Ethereum Foundation Is Not the Center, but One Node”

Ethereum co-founder Vitalik Buterin said the Ethereum Foundation (EF) is not the “center” of Ethereum, but rather one node with a clear purpose.

According to Wu Blockchain, Buterin explained that the EF will operate as a smaller and more long-term-oriented organization going forward. The remarks emphasized that the Ethereum ecosystem is run as a decentralized structure rather than one centered on a particular foundation.

Concerns Raised That AI and Quantum Computing Could Threaten Bitcoin and Ethereum Security Models

According to Odaily, blockchain and post-quantum cryptography researchers warned that AI could accelerate advances in quantum computing, potentially affecting the security frameworks of major blockchains such as Bitcoin and Ethereum.

Alex Pruden, CEO of post-quantum infrastructure firm Project Eleven, said that the combination of AI and quantum computing may make it harder to continue trusting existing security assumptions as they stand today.

Researchers explained that AI is being used to optimize quantum error correction, one of the core challenges in quantum computing. Illia Polosukhin also said that since AI has accelerated scientific research more broadly, it could create a feedback loop that speeds up the development of next-generation quantum computers.

A key industry concern is the large-scale collection of encrypted data today with the intention of decrypting it later once quantum computers mature. Many current blockchains and internet systems rely on elliptic curve cryptography, meaning that sufficiently powerful quantum computers could theoretically derive private keys from public keys.

That said, AI is also being used for code audits, formal verification, and testing of post-quantum security systems. Researchers said future security frameworks are likely to evolve into systems of continuous adaptation rather than one-time upgrades.

Strategy’s Saylor: “This Week We Bought Bonds, Not Bitcoin”

According to Odaily, Michael Saylor, founder and executive chairman of Bitcoin treasury firm Strategy, said on X, “This week we bought bonds, not Bitcoin.”

Saylor added, “₿itVac is charging.” Strategy has continued to draw market attention for its Bitcoin acquisition strategy.
