[Frontend] Universal Web3 Transaction Simulator & Gas Estimator

🚀 Feature Overview

Before a student submits a transaction, the UI should simulate the transaction execution, showing exactly what state will change and precisely estimating gas limits to prevent failed transactions.

This is a complex, MVP-critical feature designed to elevate the capabilities and stability of the Web3 Student Lab platform.

🛠️ Implementation Requirements

• Integrate with backend simulation endpoints or RPC eth_call/Stellar equivalents.\n- Build a detailed UI parsing simulation traces into human-readable state changes.\n- Implement auto-adjusting gas buffers based on network congestion.

🔧 Technical Specifications

• Adherence to strict architectural boundaries.
• High test coverage requirements (>90%).
• Integration with existing infrastructure cleanly.

✅ Acceptance Criteria

• Feature implemented according to requirements.
• Unit and integration tests passing.
• Security review completed.
• Comprehensive documentation written.

🎓 Difficulty Level

Advanced - Requires deep understanding of the relevant stack and best practices.
