The Ethereum Foundation has outlined interoperability as its top priority for improving user experience over the next year, with a strategy that places emphasis on intent-based architecture, faster message-passing, and unified standards across the network.
Interoperability as the Key Challenge
In a blog post published on Friday, Ethereum Foundation researchers said the next six to twelve months will be dedicated to addressing fragmentation within the ecosystem. With multiple layer-2 protocols now extending Ethereum’s scalability and functionality, developers are facing new challenges in ensuring that users can operate seamlessly across chains.
“At its simplified core, the key ingredients to accelerate interop boil down to unlocking fast crosschain message-passing and standardisation,” the post explained. Settlement delays and inconsistent standards are currently creating bottlenecks for developers and users alike.
The Foundation’s focus will be on enabling users to express their intended outcomes, or “intents,” while the network automatically executes the underlying technical transactions across chains. Metrics such as confirmation speed, time-to-inclusion, layer-2 settlement efficiency and signatures per operation will guide the optimisation efforts.
Three Streams of Development
Ethereum’s interoperability work has been divided into three distinct streams: initialisation, acceleration and finalisation.
The initialisation stage is centred on building intent-based architecture. It includes three major projects: the open intents framework, the Ethereum interoperability layer and interoperability standards.
The open intents framework is designed as a modular and lightweight stack for developers to integrate intents into Ethereum applications. Production smart contracts using the framework are already active, with security audits expected to be completed in the third quarter of this year. Crosschain validation trials are also anticipated before year-end.
Alongside this, the Ethereum interoperability layer is being developed as a trustless cross-layer-2 transport system. Led by the team behind ERC-4337, Ethereum’s account abstraction standard, this initiative aims to provide prescriptive execution across layer-2 solutions.
The final element of the initialisation stage is the creation of interoperability standards. These will ensure consistency in the user experience across chains.
New Standards for Crosschain Operations
A series of proposed Ethereum Request for Comments (ERC) standards are already under development. ERC-7828 and ERC-7930 focus on interoperable addresses, while ERC-7811 standardises asset consolidation so that the same token can be treated as a single balance across different chains and wrappers.
Further standards include ERC-5792, which formalises multi-call flows, ERC-7683, which defines a common intent format, and ERC-7786, which creates a neutral messaging interface. The latter is designed to make bridges and verification backends interchangeable.
Speed and Finalisation Phases
The second stream of work is centred on accelerating performance at every layer of the Ethereum ecosystem. This includes cutting down settlement delays and optimising the flow of messages across chains to improve the responsiveness of applications for users.
The third stream, described as the finalisation phase, is focused on strengthening the system’s foundations. Current efforts are directed towards advancing zero-knowledge proof integration and improving finality times on the main Ethereum chain. These improvements are expected to enhance both the security and efficiency of the network.
A Unified Path Forward
By investing in interoperability, the Ethereum Foundation is tackling one of the most significant challenges to user adoption. With the rapid rise of layer-2 solutions, fragmentation has become a pressing issue, leaving users navigating a patchwork of systems.
The Foundation’s three-stream strategy aims to unify these experiences, providing developers with the tools and standards needed to build seamlessly interconnected applications. If successful, this could set the stage for a smoother and faster Ethereum experience, benefiting both end users and the broader Web3 ecosystem.
