Quality-first update: no fake freshness, no recycled June 20 list, and no filler when a story lacks a new source or useful reader angle.
Cointelegraph listed the notorious sandwich-attack bot Jaredfromsubway.eth being exploited for $7.5 million as the top 24-hour crypto story. Reader takeaway: even aggressive MEV infrastructure can become an exploit target.
The Jaredfromsubway.eth headline matters because sandwich bots already sit inside the user-risk layer of decentralized trading. Readers should treat high-slippage swaps and unfamiliar routing as live security concerns.
Today's exploit headline shows why the security desk should watch not only bridges and wallets, but also MEV bots, private routing, and transaction-ordering infrastructure.
Cointelegraph reported the European Commission is seeking comment on how MiCA should be adjusted for the next phase of crypto regulation.
Cointelegraph reported the consultation covers scope and definitions, e-money and asset-referenced tokens, crypto-asset service providers, and topics MiCA 1.0 did not fully cover such as DeFi and prediction markets.
Cointelegraph reported policy experts saying stablecoins treated as payment infrastructure would require stronger focus on redemption, liquidity, reserve management, resilience, and supervision.
Cointelegraph reported Coinbase wants MiCA 2.0 to recalibrate rules around reserves, rewards, and multi-issuance models so euro stablecoins can compete more effectively.
Cointelegraph reported experts saying regulators may examine governance rights, admin keys, front-end control, revenue capture, upgradeability, and identifiable influence when judging DeFi decentralization.
Cointelegraph reported EU regulators are asking whether crypto-asset service providers should conduct due diligence on DeFi platforms they make available to clients.
Cointelegraph reported EU policy experts warning event-contract platforms can run into overlapping frameworks depending on the contracts offered.
Cointelegraph reported the comment period ends Aug. 31 and cited an expert view that concrete proposals may not arrive before 2028 because of complexity and EU legislative pace.
Cointelegraph reported $13 billion in Bitcoin options open interest is set to expire on June 26, with bears currently holding the stronger setup.
Cointelegraph reported Deribit accounts for $10.4 billion of open interest, or about 79% of the June 26 Bitcoin options expiry setup.
Cointelegraph reported put options could have a net advantage of roughly $1 billion to $3.4 billion depending on where Bitcoin settles.
Cointelegraph reported 78% of Deribit call open interest sits at $72,000 or higher, far above the current price zone.
Cointelegraph reported a Bitcoin finish between $57,000 and $61,000 would favor put instruments by about $3.4 billion.
Cointelegraph reported even a 12% rally from the current $63,000 area would probably not flip the June expiry in favor of calls.

CoinDesk listed SOL around $73.04, up about 5.01%, making it the strongest visible large-cap move on the live homepage snapshot.
CoinDesk listed the CD20 index up about 1.38%, which is a recovery signal but not enough by itself to erase the options and ETF-flow risks.

CoinDesk reported Algorand says migrating live blockchain infrastructure to post-quantum cryptography will take years and must begin before a future Q-Day risk.
CoinDesk reported Ethereum and Solana ecosystems have elevated post-quantum planning, reinforcing that cryptography migration is becoming an industry-wide research track.
CoinDesk reported Alchemy's AI-driven AgentCard can access Visa Intelligent Commerce so AI agents can make purchases on behalf of consumers.
CoinDesk reported each AgentCard receives a dedicated email address and phone number, giving agents the credentials needed to sign up for services and receive verifications.
