• Resume Mechanism — Automatically resumes interrupted transactions (energy rental, approval, or transfer confirmation) after page refresh or connection loss
• TronLink Integration — Connect via TronLink wallet adapter for secure transaction signing without exposing private keys
• Private Key Mode — Alternative direct signing mode for automated or headless usage
• CSV Import — Upload recipient lists via CSV file for bulk transfer preparation
• Simulate Before Send — Estimate energy cost before committing to a transfer
• Transaction Records — View historical TRC20 transfer records for the active wallet
• Mainnet / Shasta Testnet — Supports both environments for development and production
