# ZapBuy

**ZapBuy** is a fast, no-frills way to buy Energy: you **send TRX directly** to TronSave's default bot address, and the system automatically creates a **1-hour Energy rental order** sized to the amount of TRX received. No account, form, or extra steps required.

For the conceptual overview of all order types, see [Order Types](/concepts/order-types.md).

## How it works

1. **Calculate the TRX to send** using the [Energy Calculator Tool](https://tronsave.io/tools/zapbuy). You can buy Energy flexibly based on your needs — you are not limited to fixed multiples.

2. **Send TRX** to TronSave's bot address:

```ini
TLx8h8fjv5pyuxCu292ZgjbU14XZSiLGg4
```

3. The system calculates how much Energy your TRX can rent.
4. A **1-hour rental order** is created automatically.
5. The Energy is delegated directly to the sender's wallet (if eligible to receive).

{% hint style="info" %}

* You must rent **at least 65,000 Energy**. Requests below 65,000 Energy are **ignored**, and **no order is created**.
* ZapBuy only works when your order can be **matched immediately** with available Energy. If no match is found, you will not receive Energy.

## Frequently asked questions

**Q: Can I choose a rental duration other than 1 hour?**\
A: No. ZapBuy is designed for quick, fixed-duration rentals of 1 hour.

**Q: What happens if I send more TRX in one transaction?**\
A: The system still creates **a single order**, sized to the appropriate Energy amount.

**Q: I sent TRX but didn't receive Energy — why?**\
A: Check the following:

* You sent TRX from a **regular wallet**, not a **smart contract** or **exchange**.
* The amount you rent is at least **65,000 Energy**.
* Your transaction was **successfully confirmed on the TRON blockchain**.

If you have met all of the above and still did not receive Energy, contact us **immediately** at <https://t.me/wantingtrx>.
