It is powered by [Synthetix](https://synthetix.io/) smart contracts, and runs on [Optimism](https://optimism.io) Ethereum L2. Dynamic pricing is enabled by [Pyth](https://pyth.network/) oracle feeds.
Features include: * **Non-custodial:** We never take custody of your funds. Trustless smart contracts do all the heavy lifting. * **Deep liquidity:** We're able to provide deep liquidity for our users, thanks to our partners' simulated liquidity algorithms. * **Instant transactions:** Nearly instant transactions are but just one of the benefits of using Layer 2 technology. * **Low fees:** Built on Optimism Ethereum Layer 2 with low gas fees. {% hint style="info" %} **Please note:** Decentrex is currently in beta testing. Any action you take on the platform is strictly at your own risk, please act only under thorough consideration. {% endhint %}
