# Router settings (DEX Aggregator)

DeDust Router searches for the best available swap across [DeDust pools](/en/liquidity/pools.md) and supported third-party liquidity sources on TON. It can split your input across several parallel routes and use intermediate tokens when a direct pool does not offer the best result.

To open Router settings, go to [**Swap**](https://dedust.io/swap) and select the gear icon. After changing the settings, select **Save**.

### Routes and steps

A **route** is a path that carries all or part of a swap. When several routes are used, Router splits the input amount and sends each part through a different path.

A **step** is one swap inside a route. For example, `TOKEN A → TON → TOKEN B` is one route with two steps.

By default, Router can use up to:

* **4 routes**;
* **2 steps per route**.

More routes and steps give Router more possible paths to compare. It can improve the quote, but may also increase execution complexity and [network fees](/en/protocol/fees.md#network-fees).

> **Important:** Transactions on TON are not atomic. In a multi-step route such as `TOKEN A → TOKEN B → TOKEN C`, the first swap can succeed while the second one fails. If that happens, `TOKEN B` remains in your wallet instead of the selected output token. You can then swap it separately or keep it.

### Avoid pools with low TVL

Enable this option to exclude pools whose total value locked is below the selected threshold. A low-TVL pool may show an attractive quote but can be more sensitive to price movement and [slippage](/en/trade/price_impact.md#slippage-and-slippage-tolerance).

The option is disabled by default; when enabled, the initial threshold is `$10K`.

### Avoid highly volatile pools

Enable this option to exclude intermediate pools whose exchange rate changed by more than the selected percentage during the selected period.

Configure two values:

* **Volatility** — the maximum difference between the pool's lowest and highest exchange rates during the period;
* **Period** — how far back Router checks the pool's exchange rate.

The option is disabled by default; when enabled, it starts with `10%` over `1 minute`.

### Minimal savings

Enable this option to use intermediate tokens or split the swap into several routes only when the estimated benefit is greater than the selected percentage. Otherwise, Router selects a single route.

Router accounts for the additional network fees of a multi-route swap. It proposes the more complex route only when its overall benefit covers the extra network fee and exceeds the selected Minimal savings threshold.

### Third-party protocols

Router can include liquidity from other TON trading protocols in addition to DeDust pools. Each source can be enabled or disabled separately.

Currently supported DEX protocols:

* **STON.fi v1** — enabled by default;
* **STON.fi v2** — enabled by default;
* **TONCO** — enabled by default.

Currently supported memepad sources:

* **Memes Lab** — disabled by default;
* **Other memepads** — disabled by default.

Memepad sources allow Router to trade supported tokens before they migrate to a DEX. They are disabled by default.
