DeepBook Protocol (DEEP), a dApp in the Sui (SUI) layer-1 blockchain ecosystem, has announced the testnet launch of DeepBook Predict, its on-chain options and prediction market infrastructure. Predict is an options primitive that can be combined with DeepBook's spot and margin features, supporting the creation of binary markets, call and put options, leveraged products, and structured products. DeepBook explained that it has implemented an institutional-grade options pricing model on-chain through an options oracle developed in collaboration with Block Scholes. The protocol added that Predict integrates with its margin function to enable leveraged positions and supports transaction finality under 400ms on the Sui network. "The on-chain options market TVL is currently around $100 million, which is still an early stage," DeepBook stated, adding that "Predict will accelerate the expansion of DeFi options infrastructure."

LayerZero CEO Bryan Pellegrino has refuted claims from KelpDAO regarding a recent rsETH security incident. Citing on-chain records, Pellegrino stated on X that KelpDAO itself changed the rsETH cross-chain configuration from the default multi-DVN structure to a 1:1 single DVN mode in April 2024. He explained that LayerZero's official documentation warns against using this setting in a live environment and that the team has consistently recommended a more secure multisig structure. Pellegrino added that most related transactions during the period the 1:1 structure was active originated from rsETH. He is now awaiting a final audit report from an external security firm.

Lawyers for the victims of the KelpDAO hack are shifting their legal strategy to seize $71 million in frozen ETH, CoinDesk reported. In a court filing, they argued the incident was not a simple theft but a loan based on collateral fraud, asserting that assets obtained fraudulently can still be legally owned. The lawyers explained that the North Korea-linked Lazarus Group allegedly secured a loan of real ETH using worthless rsETH as collateral. They emphasized that under the U.S. Terrorism Risk Insurance Act (TRIA), assets linked to North Korea can be seized. Previously, Aave had requested the freeze be lifted, arguing that temporary possession of stolen assets does not confer ownership and that the funds belong to the victims, not the perpetrators.

The U.S. Federal Reserve is unlikely to pursue additional interest rate hikes, according to an analysis by Jim Smigiel, an analyst at the Nasdaq-listed financial services firm SEI (SEIC). He explained that the Fed, with its dual mandate of price stability and full employment, must consider the potential negative impact of rate hikes on the economy and the labor market. In contrast, Smigiel noted that some other global central banks, such as the ECB, are more focused on price stability, making further tightening relatively more likely. However, he added that central banks in other major economies are likely to largely follow the Fed's policy path due to concerns about exchange rate and capital market instability.
