Coinbase Payments has joined the Open Intents Framework as a core contributor, marking a significant step toward standardizing cross-chain asset movement within the Ethereum ecosystem.
The collaboration brings together major industry players, including the Ethereum Foundation, Hyperlane, Across Protocol, OpenZeppelin, and LI.FI Protocol and DeFi Wonderland to build open standards for permissionless, secure cross-chain transactions.
Cross-chain crime has surged to over $21 billion in 2025, representing a threefold increase from $7 billion in 2023, according to Elliptic research. Chain-hopping tactics now appear in 33% of crypto crime investigations spanning more than three blockchains.
The Open Intents Framework addresses growing fragmentation in Ethereum’s multichain ecosystem, where users access DeFi protocols on Arbitrum, social networks on Base, and AI agents on Mode.
Ethereum Foundation researchers identified interoperability as the top near-term priority for development in the next six to twelve months. The ongoing initiative launches with production-ready ERC-7683 implementation, an open-source TypeScript solver application, composable smart contracts, and customizable UI templates.
The framework builds on Vitalik Buterin’s 2024 vision for seamless cross-chain interoperability through Ethereum Improvement Proposals, including EIP-3370 for address standards, EIP-7683 for communication protocols, and EIP-3668 for off-chain data access.
