ZetaChain has launched an upgraded version of ZetaClient, enhancing cross-chain transaction capabilities following the UNISON (V36) mainnet upgrade. The update introduces multi-deposit and multi-call functionalities for single cross-chain transactions, allowing Universal Apps to execute multi-step, multi-chain contract calls on the Universal EVM without heavy reliance on off-chain orchestration. This advancement aims to improve capital efficiency and user experience in Universal DeFi/DEX operations and facilitate AI agents in executing cross-chain workflows more effectively. The upgrade also boosts system performance by improving inbound stability under high load conditions, accelerating key signing processes, and enhancing observability. Additionally, it expands native interoperability support for Sui and Solana, enabling more complex operations with larger payloads and specific functions like withdrawAndCall.
