In this lesson, we’ll build a simple and intuitive frontend interface that allows users to input the staking amount and trigger cross-chain staking transactions through a web UI.
We’ll also design the basic interaction logic to ensure a smooth user experience.
🎯 Goals
✅ Design a clean HTML + CSS interface for cross-chain staking
✅ Create an input field for users to enter the amount of SOL to stake
✅ Add a “Stake” button to trigger the backend cross-chain staking API
✅ Show real-time feedback on the transaction status (success or failure)
2. Designing the HTML Structure
📄 File: index.html
1📌 Key Features:
✅ input#amount: Lets users input the staking amount
✅ button#stakeButton: Triggers the backend API to execute the cross-chain staking
✅ div#statusMessage: Displays success or error messages
3. Connecting the Frontend Logic
📄 File: app.js
📌 Interaction Highlights:
✅ Prevents duplicate submissions by disabling the button during the transaction
✅ Calls your backend /api/cross-chain-stake endpoint
✅ Provides clear and real-time user feedback on transaction status
