# Simplify DeFi with gasless infrastructure

Expecting users to pay gas fees creates unnecessary roadblocks in your product experience. Our API simplifies crypto for users by abstracting away the complexities of gas fees.

[Get started](https://dashboard.0x.org/)

### Improve onboarding and conversion

Simplify user flows and allow your users to start trading with any token that’s in their wallet.

### Fast setup

Get real-time quotes and swaps with just a few lines of code.

### End to end gasless solution

We’ve built a comprehensive solution that covers approvals and swaps. Gas is abstracted away into the backend.

### Protection for users

Shield users from MEV with proprietary Slippage Protection and Request for Quote orders from private market makers.

## Scale user adoption by building frictionless crypto experiences

### Eliminate complex interactions in your application

#### Without Gasless API

The first time a user sells a new token from their wallet, they must perform a separate one-time transaction to set an approval for it. This transaction costs gas, so the user needs to hold a small amount of the chain’s native token to pay for it. Users also need to maintain token balances to pay network fees on every subsequent transaction.

\*Transaction fees vary based on the network traffic and prices.
