# Entering the DeFi 2.0 stage
the industry focuses on the improvement of capital efficiency. Frax introduces the mode of "partial performance algorithm stability", Alchemix launches "future income mortgage lending", and Uniswap V3 improves capital efficiency through "interval market making". However, in this stage, users still focus on active operation, and users need to manually adjust between urban areas and frequently switch agreements to find high returns, and lack the ability to respond dynamically to market risks, and asset losses are prone to occur due to delayed operations due to drastic market fluctuations.

Dealin In view of this pain point, the intelligent strategy engine is constructed. The engine uses big data analysis and machine learning algorithms to monitor market dynamics in real time and automatically adjust investment strategies according to the risk preferences and return targets set by users. For example, when the market volatility intensifies, the system will automatically reduce the allocation ratio of high-risk assets, increase the holding amount of stable assets, and help users to effectively avoid risks. At the same time, Dealin also provides smart reminders to timely promote market changes and strategy changes to users, to ensure that users can always make the best decisions.

DeFi 3.0 Further explore ecological collaboration and cross-chain communication, Stargate, Avalanche Bridge and other cross-chain protocols break single-chain ecological barriers, and Yearn Finance and other aggregators realize strategy automation. However, at this time, the automation still stays at the level of process solidification, the aggregator strategy cannot be dynamically adjusted according to the users' individual risk preference and asset status, and the degree of wisdom is limited, so it is difficult to cope with the complex and changeable market environment. Dealin Major breakthroughs have been made in cross-chain technology, adopting advanced cross-chain bridge technology to realize the seamless interconnection of mainstream public chain assets such as Ethereum, BSC and Solana. Users can freely transfer and trade assets on different chains, without cumbersome cross-chain operations and high fees. At the same time, Dealin's smart contracts are carefully designed and rigorously audited, and are highly secure and reliable. In terms of user personalization services, Dealin creates tailored investment solutions for each user through in-depth analysis of user asset data and transaction behavior. Both conservative investors and aggressive investors can find the most suitable investment strategies on the Dealin platform, truly realizing the personalization of financial services.
