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.

The cross-chain liquidity aggregation protocol LI.FI announced the launch of LI.FI Intents, a modular full-stack execution engine that competes for order execution through a network of specialized solvers, built on the reference contract of the Open Intents Framework.The Open Intents Framework is a public goods initiative led by the Ethereum Foundation, with contributions from over 30 teams including LI.FI, OpenZeppelin, Wonderland, Uniswap Labs, Hyperlane, and others. LI.FI Intents is a large-scale implementation of OIF in a production environment, providing stablecoin payments, access to real-world assets, and compliant on-chain liquidity for enterprises.LI.FI stated that historically, the intent stack has been too rigid, forcing all applications to adopt a single execution model. Teams had to build from scratch to solve multiple issues such as order expression, solver networks, cross-chain settlement, and fill validation. OIF empowers teams with the freedom to choose and customize through modular components, reducing the time to build intent applications from months to days.The Ethereum Foundation commented, "The Open Intents Framework is designed as a shared infrastructure for intents, a modular and open framework for the ecosystem to collaboratively build intent applications. This framework takes the next step: achieving large-scale adoption."

Aave founder and CEO Stani Kulechov tweeted that the valuation of DeFi lending protocols should not primarily refer to TVL, as it measures net collateral rather than lending activity. Comparing data from the end of 2025, Aave's supply scale is about $52 billion, active loans about $22 billion, loan interest flow over $700 million, and DAO retention about $150 million; SoFi has deposits of about $37.5 billion, a loan book of about $38 billion, loan income of about $1.8 billion, and net profit of about $481 million.Stani stated that in traditional finance, deposits are liabilities or capital costs, and loans are interest-bearing assets, with lenders typically assessing based on the loan book, interest income, interest spread, and asset growth; however, the DeFi market mainly focuses on TVL and DAO retention fees. He believes that Aave is closer to over $700 million in lending business under a traditional financial accounting framework, rather than a $150 million revenue protocol; TVL is not the revenue basis for lending protocols, but the loan book and interest flow are the core.
