What is a TRON energy aggregator

An energy aggregator sits between you and several energy suppliers. You place one order; the aggregator fills it from a supplier that has the energy, for example the cheapest one that can fill it. The energy reaches your address the same way as from any provider: an on-chain delegateResource^[1] for the amount you need (64,285 or 130,285 for one USDT transfer).

Why buyers use one

Under Stake 2.0, energy comes from TRX that suppliers stake^[1]. Each supplier has a limited amount and its own prices, so:

• a supplier can run out — an order it cannot fill means waiting, or sending the transfer without energy and burning TRX at 100 SUN^[2];
• prices differ between suppliers and through the day;
• terms differ — minimum amounts, rental lengths, payment methods.

An aggregator absorbs these differences: it compares what its suppliers can deliver and fills the order from one of them, so the buyer deals with one account, one price list and one API.

Single supplier:   Buyer ---> [Supplier]   (out of energy: no order)

Aggregator:        Buyer ---> [Aggregator] ---> [Supplier A]  cheapest with enough energy
                                           \--> [Supplier B]  next if A cannot fill it

What it does not change

• The chain sets the cost of a transfer, not the aggregator: 64,285 or 130,285 energy, depending on the recipient.
• Energy still goes to the sender’s address. Delegate to the wallet that sends the USDT, not to the recipient — see which address to enter.
• It cannot sell energy no supplier has. When every supplier is out, an aggregator is out too.
