ArcadiaFi Stung by $2.5 Million Cross-Chain Hack

The DeFi industry has been shaken again by a security incident. Arcadia Finance , a DeFi protocol, lost around $2.5 million due to a cross-chain exploit on July 15, 2025. The exploitation was done through weaknesses in a cross-chain bridge, which enabled the attackers to shift assets to Ethereum.

Blockchain security company PeckShieldAlert disclosed that the attackers quickly exchanged the pilfered funds for 840 ETH, essentially washing the digitalassets. The attack contributes to the rising number of bridge-associated hacks within DeFi and reiterates concerns over the security architecture of decentralized protocols.

With increasing adoption within DeFi, so too increases the complexity of such attacks, reemphasizing the need for more robust cross-chain security measures and tightening of  audits.

Vanguard Becomes Largest Owner of MicroStrategy (MSTR)

In a major institutional action, Vanguard has emerged as the largest owner of shares in MicroStrategy (MSTR), with over $9 billion worth of shares . This comes as a surprise especially considering the company's past reservations about Bitcoin and digital assets.

A former vocal critic of BTC, Vanguard had already turned down listing Bitcoin ETFs on its platform due to crypto's volatility and lack of intrinsic value. But now, by holding a significant interest in Strategy (former MicroStrategy), they're essentially sitting on exposure to more than 601,550 BTC, valued at $70.28 billion at today's prices.

Strategy, under the leadership of Michael Saylor, has been a proxy for exposure to Bitcoin in the stock market. Vanguard's shift signals not only a tactical move in indexing, but also a weakening position on crypto's place in contemporary finance.
