Tutorial on Blend Protocol, an over-collateralized lending platform on Stellar. Covers how the protocol works, testnet UI walkthrough, and how developers can build on top of it using Soroban smart contracts.
This video provides a comprehensive guide to Blend Protocol on Stellar, explaining over-collateralized lending mechanics where users deposit more collateral than they borrow. The speaker covers key concepts like loan-to-value ratios, oracle pricing, and liquidation processes. Use cases discussed include leveraged trading, short selling, decentralized stablecoin issuance, and borrowing stablecoins against native asset holdings for tax efficiency. The tutorial includes a testnet demonstration of depositing XLM, borrowing USDC, and repaying loans through the Blend interface. Finally, the speaker shows developers how to programmatically interact with Blend contracts using Soroban, examining contract functions, request structures, and test suite examples that demonstrate building composable DeFi applications on Stellar.
