ERC-7683: A New Standard for Inter-Chain Intent Collaboration on Ethereum

The Solution to the Ethereum Sharding Problem

With the rise of Layer 2 solutions and various DeFi projects, the Ethereum ecosystem is facing an increasingly serious problem of liquidity fragmentation. Assets and transactions are scattered across multiple decentralized platforms and protocols, lacking effective connections and interoperability, resulting in liquidity on each chain being able to operate only within isolated "small circles," exacerbating the overall cost of fragmentation.

In response to the launch of over 100 new Ethereum chains in 2024, the Ethereum Foundation announced on February 20 the opening of the Open Intents Framework (, aimed at providing a "single-chain-like" seamless trading experience for Ethereum. The framework consists of three core components:

1. Open-source solver: Written in TypeScript, it can monitor on-chain events and handle intents, with protocol independence.

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

3. UI Template: Provides pre-built customizable user interfaces for easy access to intent products for end users.

ERC-7683: A Universal Standard for Cross-Chain Intent

ERC-7683 is a general standard for cross-chain intentions on Ethereum developed jointly by multiple institutions in the industry, aimed at providing a unified and standardized cross-chain operation framework for Ethereum and other blockchains. Its core content includes:

1. Cross-chain order structure: ensuring consistency between different blockchains and platforms.

2. ISettlementContract interface: A standardized method for handling settlement processes.

3. Fulfil mechanism: Allows participants to compete to fulfill cross-chain intentions in a shared network.

4. Filling Deadline: The expiration time for marking cross-chain intent.

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

6. Order Data: Contains the core parameters of cross-chain transactions.

The main advantage of ERC-7683 lies in achieving seamless cross-chain interactions and enhancing governance capabilities. It simplifies the cross-chain operation process, reduces technical barriers, and improves the efficiency of decentralized autonomous organization )DAO( in conducting cross-chain governance across multiple platforms.

The Development Trends of Intent and DeFAI

Intent and DeFAI, as derivative concepts of DeFi, are both committed to solving scalability and liquidity issues. Intent aggregates liquidity through UNI and ERC-7683, while DeFAI leverages AI technology to achieve automated trading.

Intent primarily simplifies user interaction through the "intent-driven trading" mechanism, optimizes strategy execution, and addresses liquidity bottlenecks through cross-chain technology. DeFAI, on the other hand, utilizes AI technology to analyze market trends and provide risk control and decision support.

Despite the increasing levels of abstraction, solving the issue of liquidity fragmentation requires optimizing existing protocols rather than simply relying on the increase of abstraction layers.

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

Uniswap plays an indispensable role in promoting the development of ERC-7683, mainly based on the following points:

1. The liquidity advantages of Uniswap V4: introduces more flexible and efficient liquidity pool management, optimizes capital efficiency, and reduces deployment and exchange costs.

2. The potential of Uniswap X: It is expected to enhance cross-chain interoperability and may become an important platform for executing cross-chain intentions based on ERC-7683.

3. The implementation of cross-chain protocols relies on: ERC-7683 is likely to depend on the liquidity pools, automated market making, and cross-chain trading capabilities provided by Uniswap.

The Practical Meaning of Intent

The concept of "intention" originates from an article published by Paradigm in June 2023, aimed at addressing the issue of fragmented liquidity. The launch of ERC-7683 provides a superior solution to this problem.

The intent and ultimate goal of ERC-7683 is to inject new vitality into Uniswap by implementing more efficient trading, creating richer functionalities, and enhancing cross-chain interoperability, attracting more users and liquidity. This will transform Uniswap from a liquidity-dispersed AMM into a more comprehensive DeFi platform.
