TRC20 Batch Sender
A web-based tool for performing batch TRC20 USDT transfers on the TRON blockchain. Built with Next.js and TronWeb, it streamlines multi-recipient transfers with automatic energy rental and transaction resume support.
Features
- Batch Transfers — Send USDT to multiple recipients in a single contract call, saving time and reducing overhead
- Auto Energy Rental — Automatically estimates required energy before transfer and rents it on-demand to minimize TRX burn as gas fees
- 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
