# Exchange

Token swaps at DeFi Saver are done in a fully non-custodial way, with your tokens being swapped on-chain using decentralized exchanges and DEX aggregators.

As for all transactions done at DeFi Saver, to perform a swap, a **smart wallet** is needed (if one has not already been deployed for the connected account/wallet).

*DeFi Saver takes no fee for swaps on the Exchange dashboard.*
{% endhint %}

## DEX Aggregators

DeFi Saver Exchange essentially serves as a DEX meta-aggregator, combining various DEX aggregators as well as numerous direct DEX integrations.

The DEX aggregators used on DeFi Saver are:

* 1inch
* Paraswap
* Kyberswap
* 0x
* Odos
* Bebop

\
The four direct DEX integrations are:

* Uniswap V2
* Uniswap V3
* Curve
* Sushiswap

\
By implementing the meta-aggregator, DeFi Saver's Exchange feature provides users with the best swap routes, while also providing additional tools such as Advanced Mode, which you can learn more about in our Use-case article.

In cases where slippage settings might be preventing the transaction from succeeding, our interface will offer users an alternate swap route:

*The Limit Order strategy automatically checks if the price trigger is met with the following time intervals:*

* *Mainnet - Approximately every 30 seconds*
* *Arbitrum - Approximately every 10 seconds*
* *Other supported L2s - Approximately every 20 seconds*
  {% endhint %}
