Intents may become the key to solving the complexity issues in Decentralized Finance.

In the cryptocurrency field, the complexity of DeFi operations has always been a major issue for users. In the past, users needed to execute a large number of cumbersome steps to complete a simple operation, which not only was time-consuming and labor-intensive but also prone to errors. However, an emerging technology called "Intents" ( is bringing hope for solving this problem.

Intents are essentially declarative instructions where users simply express their desired end goal without needing to concern themselves with the specific implementation process. For example, a user can simply state, "I want to exchange 100,000 FRAX for as much USDC as possible," without having to personally execute a series of complex trading steps.

Unlike traditional imperative trading, Intent allows the outsourcing of trade creation to third-party "solvers", while users still retain full control over their trades. The solvers calculate the optimal execution path based on the constraints set by the user and return it for user confirmation. This greatly simplifies the user's operational process, compressing a procedure that originally required a dozen transactions into just 1-2 steps.

In fact, the prototype of intent already exists in some current DeFi applications. For example, DEX aggregators are a basic intent system that can automatically find the best trading path for users. Protocols like CowSwap go further by using order flow auctions to ensure users get optimal execution.

However, the intent system also faces some challenges. The first is how to balance the trade-off between decentralization and efficiency. A completely permissionless intent pool may be vulnerable to DDOS attacks, while a centralized permissioned system undermines the open spirit of blockchain. Secondly, issues such as MEV extraction and order flow payment need to be addressed to ensure that user interests are not harmed.

Nevertheless, intent, as an emerging middleware layer, still shows great potential. It can not only significantly simplify Decentralized Finance operations and enhance user experience but also possibly open up entirely new use cases for blockchain applications. With the advancement of projects like Flashbots and Anom, it is believed that more mature and widespread intent infrastructure will emerge in the future, paving the way for broader adoption in the crypto space.
