Vitalik Pitches Options-Based Synthetics
----------------------------------------

Ethereum creator [Vitalik Buterin](https://ethdaily.io/vitalik-on-whats-next-for-the-ethereum-foundation) published a research post proposing a design for synthetic assets and algorithmic stablecoins, using options as the base primitive to replace debt and liquidations in DeFi. The design splits ETH into long and short exposure assets tied to a strike and maturity, removing the need for real-time oracles.

Gnosis Pay Delay Module Hack
----------------------------

Gnosis Pay disclosed a bug in its delay module, the component that sits between the Gnosis Pay card and the underlying Safe wallet. Users were urged to withdraw funds, the Gnosis Chain bridge was temporarily disabled by bridge validators as a precaution, and Gnosis co-founder Martin Köppelmann confirmed all impacted funds will be reimbursed.

Fluid Rewards Infrastructure Compromise
---------------------------------------

Fluid disclosed a compromise of its off-chain Merkle rewards distribution infrastructure. An attacker submitted fraudulent Merkle roots, drained an estimated 125,000 FLUID and 51,900 GHO on May 28, 2026, and routed proceeds through Tornado Cash, according to YAM. The Fluid team stated the core protocol smart contracts are unaffected.
