Problem
Existing cross-chain communication solutions for Ethereum rollups suffer from high latency and limited bandwidth, hindering the development of real-time, scalable decentralized applications. Developers face challenges in efficiently connecting to multiple rollups, resulting in increased overhead and compromised user experience.
Solution
Polymer Hub offers a real-time interoperability solution for Ethereum rollups, leveraging a state-aware architecture to enable low-latency communication and efficient message passing. By combining message passing and state streaming, Polymer Hub facilitates an infinitely scalable network layer that matches L2 block times, allowing applications to scale horizontally across multiple rollups. This next-generation network primitive allows developers to build omnichain applications with superior UX and performance, accessing all connected rollups through a single connection.
Target Audience
The primary target audience includes app rollup developers, intent and solver projects, RaaS providers, and token issuers seeking real-time, scalable interoperability solutions for Ethereum rollups.
Features
- Subfinality client enabling real-time communication across rollups with finality protection.
- One-to-all connectivity model providing access to all current and future rollups on Polymer Hub.
- High bandwidth leveraging blockspace to scale interop verification capacity and EigenDA to scale interop data capacity.
- Scalable unit economics reducing interoperability overhead without sacrificing security and decentralization.
- Re-org protection acting as an interoperable shared state layer pre-Ethereum finality.
- Rollup-optimized state-aware architecture for proving events across connected rollups.
