# 0x

> Connect your 0x account to Portal and start swapping and bridging tokens.

## Overview

Portal integrates with [0x](https://dashboard.0x.org/create-account?referred_by=portal) so you can swap tokens and bridge across chains through Portal APIs and SDKs. This page covers the one‑time setup in 0x and the Portal Dashboard.

## Steps to enable the Portal 0x integration

### 1. Sign up for 0x

* Create or access your 0x account [here](https://dashboard.0x.org/create-account?referred_by=portal).
* Generate a 0x API key in your 0x dashboard.

<Note>Keep your API keys secure. You'll paste it into Portal in the next step.</Note>

### 2. Enable the 0x integration in Portal

1. Open the [Portal Dashboard](https://app.portalhq.io).
2. Navigate to the `Integrations` page.
3. Locate the `0x` integration and add it.
4. Paste your 0x API key for your selected Portal environment and save.

Once saved, Portal will proxy your SDK/API calls to 0x using this key securely from Portal's servers, so you won't need to embed it in your application code.

<Note>Integrations are environment‑scoped. Repeat these steps per Portal environment.</Note>

## Cross-Chain Swaps (Experimental)

<Warning>
  Cross-chain swap endpoints are experimental and require explicit enablement by both the Portal and 0x teams before they can be used. Contact your Portal account manager to request access.
</Warning>

Portal also supports cross-chain swaps through 0x, allowing you to bridge and swap tokens across different EVM chains in a single operation. Cross-chain swaps use bridge providers like Across, Relay, and Stargate under the hood.

To use cross-chain swaps, your 0x API key must have the cross-chain product enabled on the [0x dashboard](https://dashboard.0x.org). Standard 0x API keys only support same-chain swaps.

## Next steps

Implement the flow in your app:

**Same-chain swaps:**

* [Swap Tokens with 0x](/sdks/ios/guide/zerox) using the iOS SDK
* [Swap Tokens with 0x](/sdks/android/guide/zerox) using the Android SDK
* [Swap Tokens with 0x](/sdks/web/guide/zero-x) using the Web SDK
* [Swap Tokens with 0x](/sdks/react-native/guide/zerox) using the React Native SDK

**Cross-chain swaps (Experimental):**

* [Cross-Chain Swap with 0x](/apis/enclave-mpc/guide/zerox-cross-chain) using the Enclave MPC API
