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.
