How Native Interops Works Across the Elastic Network

Traditional blockchain ecosystems suffer from fragmented liquidity, scalability issues, and poor user experience—problems that ZKSync aims to resolve with native interoperability at the protocol level.

The core components enabling this include the Shared Bridge, which connects Ethereum to ZK Chains and holds funds, and the ZK Gateway, which facilitates direct and efficient cross-chain communication. The are four levels of interoperability, ranging from simple message passing to fully structured transaction bundles.

Key Ideas

Four Levels of Interoperability Enable Seamless Transactions: ZKSync’s interop framework consists of four distinct transaction types: a) InteropMessage: Basic cross-chain message passing. b) InteropCall: Cross-chain contract execution with replay protection. c) Interop Call Bundle: Atomic multi-call transactions where all steps succeed or none execute. d) Interop Transaction: Handles execution, fee management, and failure recovery—critical for token swaps and gas management.
Enhanced Liquidity & Composability Across Chains: With ZKSync’s framework, liquidity becomes shared across chains, meaning users don’t need external bridges or fragmented pools. Smart contracts on different chains can interact smoothly, allowing more complex decentralized applications to emerge while maintaining a single, unified user experience.
