On May 29, 2026, Shielded Labs security researcher Taylor Hornby identified a critical flaw in Zcash’s Orchard shielded pool, one day after Anthropic released Opus 4.8. The issue could have enabled undetectable inflation of ZEC by repeatedly spending the same note while generating different nullifiers. The disclosure was followed by an emergency response and a reported market reaction in which ZEC fell about 60%, wiping more than $4 billion in market cap.

Jun-05 price analysis reviews Ethereum, Ripple, Cardano, Binance Coin, and Hyperliquid after broad weekly declines. ETH is down 17% and trading below $1,700, while XRP fell 14% toward $1 and ADA dropped 30% after losing $0.24.

On June 5, 2026, Zcash's ZEC fell by more than 45%, sliding from above $600 to around $300 within hours after a disclosure about a critical Orchard vulnerability. The issue, found on May 29, 2026 and fixed by June 2, 2026, could have enabled undetectable counterfeiting of ZEC, though the authors said prior exploitation was unlikely and cannot be proven either way due to privacy.

A Polymarket user says he lost about $500,000 after a market tied to Strategy's first Bitcoin sale in years was resolved against his position. The dispute centers on whether the outcome should hinge on BTC being sold by 11:59 ET on May 31, or on public confirmation that arrived via an SEC 8-K filed on June 1.

On June 1, 2026, Swissblock said Bitcoin was "on the edge of a breakdown" after losing a key "Cost Basis Zone" that had supported prior consolidation. In early Asian trading on Tuesday, BTC fell to $70,000, down 3.8% on the day and 8% over the week, while analysts pointed to downside risk if price fails to reclaim the $72,000–$79,000 range.

Strategy reported selling 32 BTC for about $2.5 million between May 26 and May 31, with the funds earmarked to support distributions tied to its preferred stock.

In Q1, XRP underperformed even as the XRP Ledger's on-chain indicators strengthened. XRP's market cap fell 26% QoQ to about $82 billion and its price dropped 27% to $1.34, while average daily XRPL transactions rose 35% from 1.83 million to 2.48 million. The quarter also saw RLUSD reach a $340.3 million XRPL market cap and tokenized real-world assets climb 124% QoQ to $2.25 billion.

A Hyperliquid vault called “Long HYPE & BTC, Short Garbage” recorded a 638% APY over the past month while holding about $3.03 million in total value locked. The strategy runs 70% HYPE and 30% BTC on the long side and shorts a basket of at least 10 high-FDV, high-emission coins, with shorts representing roughly 60% of notional exposure. The article notes the approach is an aggressive leveraged long-short trade and not a low-risk yield product.

Over the past seven days, crypto prices moved lower, with Bitcoin sliding from the $77,000–$78,000 area toward roughly $73,000 by Friday amid risk-off positioning. The week also featured heavy US spot Bitcoin ETF redemptions, including more than $1 billion in a single day, while Ethereum hovered near $2,000 as sentiment stayed cautious.
