ERC-7683: A New Standard for Ethereum Cross-Chain Collaboration

The Ethereum ecosystem is facing the challenge of liquidity fragmentation. With the rise of numerous L2 solutions and DeFi protocols, assets and transactions are spread across multiple platforms, making it difficult to unify liquidity. To address this issue, the Ethereum Foundation has launched the Open Intents Framework(, aimed at achieving a "single-chain-like" seamless trading experience.

The Open Intents Framework consists of three core components:

1. Open-source Solver: Written in TypeScript, can monitor on-chain events and handle intents. It has protocol independence and supports multiple functionalities.

2. Composable Smart Contracts: Based on the ERC-7683 standard, it defines the logic for interpretation, execution, and settlement of intents.

3. UI Templates: Provides customizable user interfaces for end users to access intended products.

ERC-7683 is the core of the framework, jointly developed by Across and Uniswap Labs. It provides a unified standard for cross-chain operations, mainly including:

• Cross-chain order structure: ensure consistency between different blockchains.

• ISettlementContract interface: standardized settlement process.

• Fulfil mechanism: allows participants to compete to complete cross-chain intentions, improving efficiency.

• Fill deadline: The expiration time for marking intent.

• Order data types and order data: define the core parameters of the transaction.

The advantage of ERC-7683 lies in achieving seamless cross-chain interaction, simplifying operational processes, and lowering technical barriers. At the same time, it also enhances cross-chain governance capabilities, which is particularly beneficial for multi-chain management of DAOs.

Intent and DeFAI are both committed to improving the DeFi experience, but with different focuses. Intent simplifies interactions and optimizes strategy execution through an intent-driven mechanism. DeFAI, on the other hand, utilizes AI technology to address compliance and risk control issues. Both are continuously driving the development and innovation of DeFi.

Uniswap plays a key role in promoting the development of ERC-7683:

1. Uniswap V4 offers more flexible and efficient liquidity management, optimizing capital efficiency.

2. Uniswap X is expected to enhance cross-chain interoperability and provide important support for ERC-7683.

3. The market position and technical advantages of Uniswap provide a stable foundation for the implementation of ERC-7683.

The practical significance of the concept of "intention" lies in injecting new vitality into Uniswap, with the potential to trigger a new wave of DeFi enthusiasm. Through ERC-7683, Uniswap can achieve more efficient trading, richer functionalities, and stronger cross-chain interoperability. This will not only enhance Uniswap's performance but may also bring about new trading models and incentive mechanisms, attracting more users and liquidity.
