ChainCatcher message, Base announces support for the cross-chain intent messaging standard ERC-7683, which will allow users to perform cross-chain operations (such as token swaps or transfers) and unify Ethereum's liquidity.

ChainCatcher news, Arbitrum posted on X expressing support for ERC-7683 to enable cross-chain intentions, a standard that will facilitate seamless interactions with multiple Ethereum chains. Arbitrum also stated that it looks forward to collaborating with teams dedicated to chain abstraction solutions.

ChainCatcher message, Ethereum L2 solution Optimism tweeted that it will support the cross-chain intent messaging standard ERC-7683, aimed at unifying liquidity between Ethereum L2s.

ChainCatcher news, Uniswap Labs stated that there is a fragmentation issue with intent-based systems, and in collaboration with AcrossProtocol, they proposed the ERC-7683 standard, aimed at addressing this issue through a universal filling network.The ERC-7683 works by having users sign cross-chain orders, user funds being held in a settlement contract, fillers competing to fill orders on the target chain, with the winning filler executing the operation and releasing the funds. Establishing a standard for intent systems will improve the experience for applications, fillers, and users, allowing applications to route intents to a broader network, lowering the entry barrier for fillers, and enabling users to achieve faster fills and lower gas fees. Notably, anyone can implement ERC-7683.

ChainCatcher message, Layer 2 solution Optimism announced the adoption of the ERC-7683 cross-chain intent standard, which was jointly proposed by Across and Uniswap Labs. This initiative aims to enable high-speed ETH and USDC transfers on the Superchain and further promote application layer interoperability across the broader Ethereum ecosystem.Optimism has integrated Across's intent-based bridging solution, providing fast bridging capabilities for the Superchain ecosystem through the Superbridge and Brid.gg interfaces. This move aligns with Vitalik's vision for the future of Ethereum, dedicated to addressing decentralization issues both within and outside the Superchain ecosystem.Optimism plans to achieve interoperability at the protocol level by adding native interoperability in the OP Stack and leveraging open-source standard interfaces to facilitate application layer interoperability.

ChainCatcher news, Vitalik Buterin posted on social media today urging industry participants to start working on ERC-3770 and ERC-7683, addressing potential issues that may affect future address space expansion for community users.He added that the main challenge of 32 bytes lies at the contract level (many contracts use mod 2** 160 to handle addresses), while ERC-3770 is at the UI level, and the two are orthogonal to each other.

ChainCatcher news, Vitalik Buterin showcased the current interface for depositing into Polymarket on X and compared it with the interface it should present, calling for the industry to work together to launch ERC-3770 and ERC-7683.

ChainCatcher news, Uniswap Labs posted on social media that intent-based systems are becoming increasingly popular, but protocols are needed to build their own filling networks. ERC-7683 can solve this problem, as all cross-chain intents follow the same sequential structure, addressing the sharding issue through a universal filling network. ERC-7683 establishes a standard for intent-based systems, improving the user experience for applications, fillers, and users.

ChainCatcher message, Uniswap Labs announced a new standard for cross-chain intent ERC-7683 in collaboration with the interoperability protocol Across, establishing a unified framework for intent-based systems to specify cross-chain operations. Uniswap Labs will adopt this standard in its cross-chain collaboration with UniswapX.
