Optimism has officially declared its support for the ERC-7683 standard focused on cross-chain intent messaging.
In Brief
With the announcement of its backing for the ERC-7683 standard, Optimism seeks to enhance the cohesion of liquidity throughout Ethereum Layer 2 ecosystems.

Ethereum Layer 2 network Optimism Optimism has thrown its support behind ERC-7683—an innovative standard designed for cross-chain intent messaging and aimed at streamlining liquidity across Ethereum's Layer 2 environments.
Developed by Across and Uniswap Labs, ERC-7683 This initiative encourages the creation of a standardized application programming interface (API) that simplifies cross-chain transaction processes. It encompasses a comprehensive cross-chain order structure and paves the way for a standard smart contract interface for settlements.
By embracing ERC-7683, various cross-chain intent platforms can collaborate and utilize shared infrastructure, streamlining services for order dissemination and filler networks. This collaboration leads to improved user experiences and heightened competition to fulfill intents, ultimately benefitting the end-users.
For users, the adoption of this standard means smoother cross-chain swapping, competitive pricing, quicker transactions, and a larger selection of choices across different blockchains. For developers and initiatives leveraging ERC-7683, it opens doors to shared liquidity, the opportunity to draw in more users through an enhanced seamless experience, and the flexibility to tailor crucial features like pricing and transaction settlements.
Furthermore, ERC-7683 strengthens the connections between the Superchain and the wider Ethereum ecosystem, boosting interoperability. This enables effortless token transfers across diverse ecosystems while minimizing slippage, enhancing speed, and bolstering security within the Superchain.
The synergy between ERC-7683 and the inherent interoperability of the Superchain is designed to eliminate the obstacles often found in cross-chain transactions, collaborating to help Ethereum achieve a scale reminiscent of internet-level capabilities.
What Is Optimism’s Superchain?
Optimism provides a Layer 2 scaling solution tailored for Ethereum, striving to enhance transaction efficiency while lowering costs. This is accomplished via optimistic rollups, allowing transactions to occur on Optimism’s blockchain, called OP Mainnet, with Ethereum handling final settlement, consensus, and data availability.
The Superchain This framework represents a network of interconnected Layer 2 blockchains utilizing the open-source OP Stack, designed to boost scalability, interoperability, and flexibility for decentralized application development.
