Ripple said it has received preliminary approval for a Crypto Asset Service Provider (CASP) license in Luxembourg under the EU’s Markets in Crypto-Assets (MiCA) framework. The approval, issued via a “Green Light Letter,” is still subject to final conditions. If fully granted, it could allow Ripple to roll out regulated cryptoasset services across the European Economic Area (EEA).

With institutional adoption accelerating, Aptos Labs CBO Solomon Tesfaye says tokenization is moving beyond the question of whether assets can be put on-chain to whether blockchain infrastructure can support markets at scale. He points to the growth of tokenized products such as BlackRock’s BUIDL fund and broader activity in on-chain finance. Tesfaye says institutions are prioritizing operational requirements such as reliability, settlement and integration over token issuance.

Ethereum layer-2 network Taiko said users should immediately withdraw funds from all bridges deployed on its network after it confirmed a security breach. The team said Taiko’s chain state verification mechanism was compromised, undermining the security assumptions of those bridges. There was no official information on how much money was at risk or whether anything had been stolen.

BlackRock has launched the iShares Bitcoin Premium Income ETF (BITA), expanding its lineup of BTC-linked products for institutional investors. The fund aims to pair Bitcoin-linked performance with income generated through an actively managed options strategy.

Ripple has made a strategic Series E investment in Flutterwave, one of Africa’s leading fintech firms. The move is aimed at pushing Ripple’s RLUSD stablecoin deeper into the region’s payment flows.

Japan's lower house has passed a bill that would place cryptocurrencies under a stock-style regulatory framework, with the measure expected to be implemented next year if approved by the upper house. The proposal could treat assets such as Bitcoin and Ethereum as financial instruments, tighten trading rules, and potentially reduce the maximum tax rate on crypto gains from 55% toward about 20%. It may also support the launch of regulated products such as spot crypto ETFs.

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.

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.
