Markets and majors
BitMart ends nine-year run as SHIB rockets on mystery
A major exchange's closure and an unexplained token rally signal shifting institutional appetite amid broader market flux.
BitMart, a spot and derivatives exchange operating since 2017, announced it will shut down by January 31, 2027 after trading halts in August. The closure erased $24.6 million in BMX token value, with the native asset crashing 58 percent in 24 hours to multi-month lows (via CoinDesk).
Shiba Inu's unexplained 36 percent surge to $0.0000057 added roughly $1 billion in market capitalization on July 26, with no announcement behind the move. Korean trading venues led volume while other dog tokens sat flat, suggesting the rally was concentrated rather than part of a broader altcoin recovery (via CoinDesk).
Toncoin unlocked 0.9 percent of circulating supply (approximately $69.9 million in TON tokens) on July 26 as traders watched whether the release would pressure the token price (via CoinDesk).
Protocols and upgrades
Solana preps 100-millisecond finality as L2 cartel solidifies
Three networks now control 90 percent of Ethereum layer 2 activity, while Solana approaches its biggest upgrade since launch.
Solana shipped major SDK updates and activated BLS public key registration on mainnet in mid-July, laying groundwork for the Alpenglow consensus upgrade planned for August through October. Alpenglow will cut finality to 100 to 150 milliseconds, marking the network's largest protocol change since inception and building on 90 days of 100 percent uptime recorded through July (via Bitcoin Magazine).
Ethereum's layer 2 ecosystem now shows extreme concentration, with Base, Arbitrum, and Optimism controlling roughly 90 percent of all L2 transactions. Base holds 60 percent of total value locked across all rollups, while Arbitrum leads TVL at 44 percent and Base follows at 33 percent, signaling the end of 50-plus failed rollup experiments (via The Block).
Aave recorded its largest network growth since 2021, adding 1,806 wallets in July as version 4's Solana deployment succeeded. AAVE token recovered to approximately $91, up sharply from June lows, driven by V4's customizable lending markets and prevention of liquidity fragmentation (via Decrypt).
Regulation and policy
Wall Street backs CLARITY Act as summer recess looms
Fidelity and Schwab urge Senate passage of crypto regulation, but the August recess threatens to derail what few votes existed.
Fidelity and Charles Schwab urged the U.S. Senate on July 26 to pass the Digital Asset Market Clarity Act. Senate Majority Leader John Thune said it won't clear before August 7 recess, requiring 60 votes to overcome a filibuster in a 53-seat Republican majority. Polymarket puts 2026 passage chances at just 34 percent (via CoinDesk).
The EU's MiCA deadline has passed, triggering a compliance wave. The transitional period for Markets in Crypto-Assets Regulation ended July 1, 2026, leaving over 80 percent of formerly registered crypto-asset service providers out of compliance. The high regulatory bar is expected to spark a new industry merger-and-acquisition wave as firms consolidate to meet requirements (via CoinDesk).
Institutions and ETFs
Bitcoin and Ethereum ETFs attract fresh capital as mood shifts
Weeks of outflows reverse as institutional investors return, even as corporate treasuries hit a record for the quarter.
U.S. spot Bitcoin ETFs saw $273 million in inflows over two weeks ending mid-July, their first sustained positive stretch after eight weeks of outflows topping $8 billion. Ethereum ETFs posted $196.4 million in net inflows from July 14 to 21, with BlackRock's ETHA leading inflows on multiple days (via CoinDesk).
Public companies purchased approximately 110,000 BTC in Q2 2026, the largest quarterly acquisition on record, bringing corporate Bitcoin treasuries to 1.26 million BTC (valued at roughly $79 billion). Notable July purchases included American Bitcoin Corp adding 8,000 BTC on July 6 and Metaplanet raising its holdings to 43,000 BTC after a July 2 purchase of 2,823 BTC (via The Block).
Security and exploits
Bridge exploits bleed $47 million as validator keys compromise
Cross-chain bridges became the week's primary target, with infrastructure attacks overshadowing pure code bugs.
AFX Trade, an Arbitrum protocol, lost $24.15 million in USDC on July 22 when attackers gained access to private keys belonging to five bridge validators. The stolen funds were withdrawn from the custodial bridge and swapped for 12,467 ETH before moving onto Ethereum exchanges (via The Block).
The Wanchain Cardano bridge was drained of $9 million on July 20 to 21 via a signature verification flaw. The validator's TreasuryCheck contract concatenated variable-length fields without proper separation or length markers, allowing an attacker to reuse a legitimate signature for a small transaction on BNB Chain to authorize a massive withdrawal of 203 million NIGHT tokens on Cardano (via DL News).
Culture and NFTs
Jimothy the raccoon becomes an official civic proclamation
A viral meme spawned a Solana memecoin, which then drew formal recognition from Seattle's city government.
On July 26, Seattle officially proclaimed summer 'Jimothy Summer' for Jimothy the Raccoon, a viral animal with a congenital spine condition affecting his neck. The raccoon went viral mid-July, and within days a Solana memecoin called JIMOTHY launched on Pump.fun, rocketing to $22 million in market cap by July 18. A city government's formal ceremony now legitimizes memecoin culture as mainstream (via Protos).
