Join us for a workshop with Matthew Krak from LayerZero titled, "The Secret to Zero Gas Fees on SKALE."

In this workshop, you'll get hands-on experience with LayerZero and learn how to send messages across multiple blockchains. We'll focus on the fundamentals of cross-chain messaging and guide you through the process of setting up communication from Chain A, B, and then C.

This workshop took place at ETHGlobal San Francisco, a 3-day hackathon held from October 18 to 20, 2024, which brought together web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
