Bitget has launched Stock+, a feature that lets users buy US stocks using crypto that is converted into USDC. The exchange says users gain ownership of the underlying shares rather than a synthetic token. Shareholder rights, including voting, are exercised through Bitget’s platform. The rollout excludes the US, UK, EU, Canada, Australia, and a range of other markets.

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.

Polygon Foundation co-founder Sandeep Nailwal said Polygon processed $309 million in stablecoin volume in Latin America in May, claiming it outpaced other chains in the region. He added that non-dollar stablecoin activity has accelerated, pointing to BRLA and COPM ranking in Polygon's top three by monthly high. A Visa-commissioned May report also cited $1.2 billion in non-dollar stablecoin supply and $10 billion in monthly transfers.

Base, the Coinbase-backed Ethereum layer-two network, plans to activate its Beryl upgrade on mainnet on June 25, 2026, at 18:00 UTC. The release introduces B20, a native token standard built into node software rather than deployed as a smart contract. Base engineers say B20 is designed as a superset of ERC-20 so tokens remain compatible with existing wallets, exchanges and decentralized applications.

Algorand says it is working to become quantum-resistant by the end of 2027. The proof-of-stake blockchain plans to do so by advancing post-quantum cryptography, including post-quantum multisignatures as a policy layer.

The exposure will be taken through a passive multi-crypto fund rather than direct token purchases.

As automated trading systems spread across DeFi, security risks are increasingly shifting beyond smart contracts. Operational security—especially around workflows and permissions—is emerging as a growing challenge alongside code-level vulnerabilities.
