Optimism is adopting the cross-chain intent standard ERC-7683 written by Across and Uniswap Labs

DeepSea, Layer 2 solution Optimism announced the adoption of the ERC-7683 cross-chain intent standard, jointly proposed by Across and Uniswap Labs. This move aims to achieve high-speed ETH and USDC transfers on Superchain, and further promote application layer interoperability within the wider Ethereum ecosystem.Optimism has integrated Across's intent-based bridging solution, providing fast bridging functionality for the Superchain ecosystem through the Superbridge and Brid.gg interfaces. This move is in line with Vitalik's vision for the future of Ethereum, committed to solving decentralization issues both inside and outside the Superchain ecosystem.Optimism plans to achieve protocol-level interoperability by adding native interoperability to the OP Stack, and promote application layer interoperability using open-source standard interfaces.
