PowerSun

If you're building on TRON and want to cut transaction costs without manually managing energy purchases, this server connects to PowerSun's marketplace for buying energy and bandwidth at rates that can cut your TRX fees in half. It exposes operations for automatic energy delegation before token swaps, transaction broadcasting with energy allocation, and pool management if you want to monetize your own idle staked TRX by renting it out. You'd reach for this when you're running a dapp or service that does frequent TRON transactions and you're tired of either overpaying in TRX burns or dealing with the operational overhead of staking and energy economics yourself. The HTTP transport makes it straightforward to integrate into existing workflows.
