# Why TronSave?

## For buyers

* **Save up to \~70%** on TRON transaction fees by renting Energy instead of burning TRX.
* **Rent in seconds** — individuals and projects alike get a simple flow on web, Telegram, and API.
* **Pay only for what you need** — choose the [amount, duration, and price tier](/concepts/order-types.md) per order.
* **Automate it** — integrate the [API](/developers/quickstart.md) or the [SDK](/developers/sdk.md) (TypeScript, Rust, Python, Java, PHP), so your app tops up resources programmatically.

## For providers (sellers)

* **Monetize idle resources** — rent out the Energy from your staked TRX at competitive market rates.
* **Earn \~18% APY** (varies with market) by sharing your staked TRX's Energy.
* **Keep full custody** — you keep control of your staked TRX while earning; see [Permission](/guides/sell/permission.md) for the exact delegation scope.
* **Stable, passive income** — set [Auto Sell](/guides/sell/auto-sell.md) and let the market match your supply.

APY figures move with the market. See [Pricing & APY](/concepts/pricing-and-apy.md) for how returns are calculated and where to check the live rate.
