NTT Payload Integration: Triggering On-Chain Actions with Cross-Chain Token Transfers

In this course, we will learn how to realize the complete process of “automatically triggering on-chain operations for cross-chain transfers” based on the Wormhole NTT framework. The course covers custom smart contract design, NTT Payload integration, contract deployment and configuration of source and target chains. In the end, we will access Wormhole Connect, build a visual interactive interface, and realize the native token+Payload cross-chain transfer between OP Sepolia and Arbitrum Sepolia.
