Multichain Staking & Lending with the Wormhole SDK

This course will walk you through building a cross-chain staking and lending protocol using the Wormhole SDK, bridging assets from Solana to Sepolia Ethereum. You’ll learn how to use the Wormhole Token Bridge for cross-chain asset transfers, interact with staking contracts using both ethers.js and solana.js, and ultimately build a fully functional DeFi application.

What You’ll Learn

Mastering Cross-Chain Staking & Borrowing: Understand how cross-chain staking and borrowing work, and learn the fundamentals of Wormhole SDK and TokenBridge

Smart Contract Implementation: Develop key smart contract functions for collateral deposits, withdrawals, minting, burning, and liquidation

Integrating Wormhole TokenBridge for Cross-Chain Asset Transfers: Handle VAA verification, asset locking, and minting across different chains.

Optimizing Development and Deploying the Project: Implementmultichainsigner management, transaction tracking, and testnet deployment for demonstration

Outline

Unit 1 - Introduction to Wormhole and Cross-Chain Staking & Lending Fundamentals

In this unit, we’ll build a solid foundation by exploring the core concepts behind cross-chain staking and lending. You’ll gain a high-level understanding of how the protocol works, learn the fundamentals of cross-chain interactions using Wormhole, and get hands-on with the basic usage of the Wormhole SDK.

Unit 2 – Setting Up the Development Environment

In this unit, we’ll walk through how to set up the development environment for this project.

Unit 3 – Implementing Cross-Chain Transfers with the Wormhole SDK

In this unit, we’ll learn how to use the Wormhole SDK to implement basic cross-chain functionality.

Unit 4 – Developing Staking & Lending Smart Contracts

In this unit, you’ll learn how to develop a simple smart contract for staking and lending, which forms the core of the cross-chain borrowing logic.

Unit 5 – Cross-Chain Data Tracking and Error Handling

In this unit, you’ll learn how to improve your project by implementing cross-chain data tracking and robust error handling to make your application more reliable and production-ready.

Unit 6 – Frontend Integration and UX Optimization

In this unit, you’ll learn how to build and connect the frontend interface for your cross-chain application—focusing on smooth user interactions, real-time feedback, and an intuitive user experience.

Unit 7 – Interaction & Deployment

In this unit, you’ll learn how to run and interact with the full cross-chain staking project locally—from starting the backend and frontend services to testing your complete workflow end-to-end.
