Pontoon Tron Energy rental APIs compared
If you only rent Tron Energy, TronSave, Feee.io, iTRX, CatFee, SaveFee, TronRental, and JustLend Buy Energy already exist. A 65k / 1h order is typically a few TRX, far below burning TRX. Pontoon does not claim the cheapest Energy tick.
Three product types
| Type | Examples | Job |
|---|---|---|
| Rental market / bot | TronSave, Feee.io, TronZap | Delegate Energy to one address for a duration |
| Protocol gasless | JustLend GasFree, TronLink | Sender wallet pays in USDT; wallet must support it |
| Merchant prepaid sponsor | Pontoon, Chaingateway Paymaster | Merchant balance tops up any target address |
GasFree owns the “users need no TRX” slogan at the wallet layer. It does not sweep a merchant deposit address or top up Mini App wallets you generated.

}Prepaid debit is live resource cost + $0.02 + 10% markup + 15 bps of resource cost ($0.05 floor). The same key sponsors BSC / TON and sweeps Checkout deposit addresses. See sponsorship and pricing.
When TronSave is enough
- One fixed collection wallet, occasional 1-hour rentals.
- You want SUN comparison and a Telegram bot.
When Pontoon fits
- Per-order addresses that must be swept automatically.
- User addresses you generated; you cannot assume GasFree.
- You also need BSC or TON.
