Developer tutorial demonstrating how to build a web-based wallet using the Stellar SDK and integrate it with Blend Capital smart contracts to enable users to deposit funds and earn yield on their holdings.
This tutorial walks through building a web-based wallet integrated with Blend Capital, an over-collateralized lending pool on Stellar. The creator demonstrates generating addresses using the Stellar SDK, depositing XLM into Blend smart contracts to earn yield, and withdrawing funds. The code walkthrough covers importing the Stellar SDK, setting up network configuration, managing wallets in local storage, simulating transactions to read token balances, and executing deposit/withdrawal operations using the Blend SDK. Key concepts include using RPC nodes for efficient data reads, the Blend pool submit function for deposits and withdrawals, and retrieving collateral balances. The tutorial shows how wallet developers can integrate Blend's products to offer yield-earning opportunities to their users.
