Zcash cratered 30–50% after an AI-assisted audit found a critical counterfeiting bug that survived four years of expert review. Security engineer Taylor Hornby at Shielded Labs used Anthropic's Claude Opus 4.8 to uncover an elliptic-curve constraint flaw in the Orchard shielded pool that could have allowed unlimited counterfeit ZEC minting. The discovery has two major implications: first, it obliterates confidence in Zcash's supply integrity even after a hard fork patch; second, it marks a watershed moment where AI formal methods outperformed human cryptographic review. Privacy coins were already under pressure—this could accelerate regulatory pushback across the sector. CoinDesk

💰 Crypto Highlights
Congress drops 7 crypto tax bills ahead of Tuesday hearing. The House Ways and Means Committee is weighing discussion drafts covering de minimis transaction relief, stablecoin taxation, and mining/staking proceeds. A formal bill could drop as early as Friday. This is the most serious legislative push on crypto tax structure to date—watch for partisan fault lines on small-transaction exemptions. CoinDesk
SpaceX's $1.77 trillion IPO is sucking capital out of crypto. The blockbuster listing (ticker: SPCX, expected June 12) is creating a rotation from risk assets into pre-IPO shares. Kraken is already offering SpaceX access through its xStocks tokenized equity platform. With Anthropic also targeting a massive IPO, crypto is competing with trillion-dollar equity launches for the same institutional dollars. Al Jazeera
Travala launches AI agent hotel bookings on Base. The travel platform now lets AI agents search and book hotels using USDC on Base, with travelers retaining final payment approval. It's a narrow but real use case for AI-agent commerce on L2s—more interesting as a infrastructure signal than a volume driver right now. Cointelegraph
🎯 What to Watch
- SpaceX IPO pricing (June 12): If the $1.77T valuation holds, expect continued capital rotation away from crypto through next week. The pre-IPO secondary market is already absorbing liquidity that would normally flow to BTC.
- House tax hearing (June 9): Seven bills sounds promising, but the real signal is whether Republicans and Democrats can agree on de minimis thresholds. No consensus means another year of tax uncertainty.
- Ethereum $1,420 support: ETH is testing 14-month lows. A break below $1,420 opens the door to $1,200 and could trigger forced liquidations across DeFi money markets.
