Vitalik posted on platform X, stating that building index-tracking assets based on options rather than debt is worth considering and trying, using options as the foundation of DeFi instead of CDPs and liquidation mechanisms. This design can avoid the extreme price fluctuations that cause severe and global liquidation effects, allowing exposure to the index to deviate from preferred exposure in a smoother secondary manner.Its key advantage is that it does not require instant oracles and can operate based on slow oracles, which are the types of oracles used in prediction markets. The design has a clear drawback, which is the need for regular rebalancing, and it remains to be clarified whether and how rebalancing can have sufficient slippage resistance.Vitalik added that compared to relying on oracles that must provide real-time answers and may be induced to give incorrect real-time answers without human remediation time, he believes that holding algorithmic stablecoins placed within such mechanisms is safer.

According to BlackHart, the DeFi project Fluid's reward distribution mechanism on Ethereum was exploited, resulting in approximately $215,000 in assets being transferred away. Fluid uses a Merkle reward list mechanism initiated by one key and approved by another key. The attacker simultaneously held both operational private keys, submitted a list that only awarded themselves, and then completed the claim with a zero-knowledge proof.The stolen assets came from three reward distributors, including 112,883 FLUID, 47,903 GHO, and a small amount of cbBTC, which were later exchanged for ETH and transferred via Tornado Cash. Fluid's lending market, treasury, DEX, and user deposits were unaffected. The team replaced the compromised keys and transferred the remaining reward funds within approximately 10 hours, but the public statement only mentioned that reward claims were paused for updates, without mentioning details about the private key leak and losses.

A white hat hacker using the alias "0xflorent" stated on X on Sunday that he has helped recover approximately 1,003 ETH (worth about $2 million) from a faulty smart contract of the Hong Coin (HONG) token sale in 2016, involving 48 investors.Hong Coin was originally designed as a community-operated decentralized venture capital fund, with the token sale starting on August 29, 2016, and ending on October 28 of the same year, but it failed to launch due to not reaching its funding goal. The contract was supposed to automatically refund investors, but a vulnerability in the refund function caused the funds to be locked for nearly a decade.0xflorent collaborated with the HONG creator to exploit an administrator function with an integer overflow vulnerability, resetting the token holders' balances and triggering the refund mechanism through specific inputs, successfully extracting the locked funds. According to Etherscan data, one investor has already received a refund of 96 ETH (approximately $192,500). Previously, on May 24, 0xflorent also recovered 19.33 ETH from another failed token sale project from 2018.

Zama's official response to Circle's freezing of the cUSDC contract event states that Circle's compliance system flagged a wallet belonging to an external depositor. Since this wallet holds funds in the cUSDC contract, the entire contract was automatically swept into a standard holding freeze. This is merely incidental damage and not a sanction against the Zama Protocol. The Zama legal team has intervened and is isolating the flagged address, and will restore access for all unaffected participants as soon as possible.
