According to ChainCatcher, Uniswap Labs posted on the social platform that intent-based systems are becoming more and more popular, but protocols are needed to build their own filling networks. ERC-7683 can solve this problem. All cross-chain intentions follow the same sequential structure and solve the sharding problem through a universal filling network. ERC-7683 establishes standards for intent-based systems and improves the user experience of applications, fillers, and users.
