## Description

Adel Akbar from LayerZero Labs presents a comprehensive workshop on cross-chain interoperability at ETHGlobal Prague 2025. Learn how LayerZero's permissionless messaging protocol enables secure asset transfers between blockchains using modular security stacks (DVNs) and immutable endpoints.

The session covers OFT token standards, LZ Compose for cross-chain actions, and the new LZ Read primitive for cross-chain queries, with live demos of contract deployment and message passing. Essential for developers building multi-chain applications or exploring secure bridge alternatives to monolithic architectures.
