Liquidity Challenges and Solutions in the Ethereum Ecosystem

1. The Root of the Ethereum Fragmentation Problem

With the rise of various L2 solutions and DeFi projects, the Ethereum ecosystem is facing an increasingly severe problem of liquidity fragmentation. This issue is primarily manifested in the fragmentation of asset liquidity across the entire ecosystem into multiple isolated chunks, scattered across L1 main chains and numerous L2 networks. Different L2 solutions compete for the total locked value (TVL), leading to assets and transactions being dispersed across multiple decentralized platforms and protocols. However, there is a lack of effective connections and interoperability between these platforms, causing liquidity on each chain to operate only within its own isolated ecosystem, which further exacerbates the overall fragmentation cost problem of Ethereum.

It is expected that more than 100 new Ethereum-related chains will be launched in 2024. This situation is akin to entering a shopping mall and seeing a dazzling array of products, but needing to use different currencies for settlement. To address this challenge, the Ethereum Foundation announced the launch of the Open Intents Framework on February 20, aiming to provide Ethereum with a seamless trading experience similar to a "single chain." The framework received support from over 50 protocols in just a few days, demonstrating its potential and the urgent demand for the ecosystem.

2. ERC-7683: The Key to Cross-Chain Intent Coordination

ERC-7683 is a universal standard for cross-chain intent on Ethereum, co-developed by well-known protocols, aimed at providing a unified and standardized framework for expressing and executing cross-chain operations, particularly between multiple L2 solutions and sidechains.

The core components of ERC-7683 include:

1. Cross-chain order structure: Defines the standard format for cross-chain orders, ensuring consistency between different blockchains and platforms.

2. ISettlementContract interface: standardizes the handling of the settlement process, allowing cross-chain transactions to flexibly execute settlements between different platforms.

3. Fulfil mechanism: Allows participants to compete in completing cross-chain intentions in a shared network, improving efficiency and reducing costs.

4. Fill in the deadline: Use a timestamp to mark the expiration time of the cross-chain intention to avoid prolonged waiting for invalid transactions.

5. Order Data Type: Use EIP-712 type hash to specify the structure and format of intent data.

6. Order Data: Includes core parameters for cross-chain transactions, such as tokens, amounts, chains, recipients, etc.

The main advantage of ERC-7683 lies in achieving seamless cross-chain interactions and enhanced governance capabilities. It simplifies the cross-chain operation process, lowering the technical barrier, allowing users to conduct cross-chain transactions more conveniently. At the same time, it also streamlines the governance process between different blockchains, which is particularly beneficial for decentralized autonomous organization (DAO) to manage efficiently across multiple chains.

3. Intent and DeFAI: The Evolution Direction of DeFi

Intent and DeFAI both originate from the financial attributes of DeFi, but they address problems in different directions. The core challenges of DeFi mainly focus on scalability and Liquidity. Intent integrates Liquidity through unified standards, while DeFAI enhances trading automation and intelligence levels using AI technology.

The core goal of Intent is to simplify the user interaction process through an "intention-driven trading" mechanism. Users can set trading intentions and strategies, and the system will execute them automatically without the need for manual intervention at each step. This not only enhances the usability of DeFi but also optimizes strategy execution and improves trading efficiency. Additionally, Intent may also address liquidity bottlenecks in DeFi through cross-chain technology, breaking down barriers between different chains, optimizing liquidity pools, thereby improving the market depth and trading efficiency of decentralized exchanges.

DeFAI, as an AI-based decentralized finance protocol, primarily addresses compliance and risk control issues in DeFi. It leverages AI technology to analyze and predict market trends, helping the protocol identify potential risks while ensuring the stability of the protocol and reducing operational risks. AI can process large amounts of market data to provide users with more accurate decision-making support, optimizing market operations and risk management.

Although the level of abstraction is constantly increasing, solving the problem of liquidity fragmentation is more like an "integration issue of the ecosystem". It not only depends on the increase in the level of abstraction but more on how to achieve it by optimizing existing protocols.

IV. The Key Role of Uniswap in Promoting the Development of ERC-7683

Uniswap plays a crucial role in the development of ERC-7683, mainly due to its core position and technological advantages in the DeFi ecosystem:

1. The liquidity advantages of Uniswap V4: The V4 version introduces a more flexible and efficient liquidity pool management mechanism, especially for providing concentrated liquidity across different price ranges. This mechanism optimizes capital efficiency, making cross-chain transactions smoother. V4 uses a single PoolManager contract to manage all mining pools, significantly reducing deployment and exchange costs.

2. The potential of Uniswap X: Uni X is expected to further enhance cross-chain interoperability and may introduce new cross-chain bridging mechanisms or integrate deeply with ERC-7683, providing more efficient channels for cross-chain asset exchange. If Uni X can provide cross-chain liquidity solutions, it will become an important platform for executing cross-chain intentions with ERC-7683.

3. The implementation of cross-chain protocols relies on: ERC-7683 depends on standardized cross-chain transaction structures and settlement mechanisms, while Uniswap holds a pivotal position in decentralized exchanges. This protocol is likely to rely on the liquidity pools, automated market-making, and cross-chain trading capabilities provided by Uniswap, especially the support from Uniswap X and Unichain.

V. The Practical Significance of Intent

The concept of "intention" can be understood as a clear trading objective or driving force. Its introduction aims to address the issue of liquidity fragmentation in the DeFi ecosystem and provide users with a simpler and more efficient trading experience.

The launch of ERC-7683 provides a viable solution to the fragmented liquidity problem. It is not just about continuing L2 scaling, but rather achieving more efficient transactions, creating richer functionalities, and stronger cross-chain interoperability through unified standards. This could trigger a new wave of DeFi innovation, attracting more users and liquidity.

Through ERC-7683, Uniswap is expected to further enhance cross-chain liquidity, reduce transaction costs, and add more trading pairs and liquidity pools based on the existing AMM model. These improvements will transform Uniswap from merely a liquidity-dispersed AMM into a more powerful and flexible decentralized trading platform, injecting new vitality into the entire Ethereum ecosystem.
