# Troubleshooting

This guide covers common issues when integrating the Intents Swap Widget.

If you can't find an answer here, please [open an issue](https://github.com/aurora-is-near/intents-swap-widget/issues) or reach out to the team.

### Balance Loading Issues

#### Balances load infinitely

**Causes & Solutions:**

1. **Missing API key** - The widget will try to use a set of RPCs by default, but Alchemy is more reliable and you can have better control with Alchemy API key.

   ```tsx
   <SwapWidget
     alchemyApiKey="your-alchemy-api-key"
     // ...other props
   />
   ```
2. **API rate limits** - Alchemy free tier has request limits. Check your Alchemy dashboard for quota usage.
3. **TON balances not loading** - TON requires a separate API key.

   ```tsx
   <SwapWidget
     tonCenterApiKey="your-toncenter-api-key"
     // ...other props
   />
   ```
4. **RPC endpoint issues** - The widget retries failed RPC calls twice before giving up. If balances still fail, check network connectivity and RPC availability.

### Dependency Conflicts

#### Conflicting package versions

**Cause:** The widget uses several libraries that your project may also use. When versions differ, bundlers may include multiple versions causing conflicts.

**Solution:** Add resolutions to your `package.json` to lock versions, example:

```json
"resolutions": {
  "valtio": "2.1.7",
  "valtio-fsm": "1.0.0",
  "@noble/curves": "^1.6.0",
  "@noble/hashes": "^1.5.0",
  "strip-ansi": "6.0.1",
  "@reown/appkit": "1.8.17",
  "@reown/appkit-common": "1.8.17",
  "@reown/appkit-controllers": "1.8.17",
  "@reown/appkit-pay": "1.8.17",
  "@reown/appkit-polyfills": "1.8.17",
  "@reown/appkit-scaffold-ui": "1.8.17",
  "@reown/appkit-ui": "1.8.17",
  "@reown/appkit-utils": "1.8.17",
  "@reown/appkit-wallet": "1.8.17",
  "@solana/addresses": "5.5.1",
  "@solana/codecs-core": "5.5.1",
  "@solana/errors": "5.5.1",
  "@solana/keys": "5.5.1"
}
```

For **Yarn**, resolutions work as shown above. For **npm** or **bun**, use `overrides` instead:

```json
"overrides": {
  "valtio": "2.1.7"
}
```

Please refer to your package manager documentation for ways of doing this:

* [npm](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#overrides)
* [yarn](https://classic.yarnpkg.com/lang/en/docs/selective-version-resolutions/)
* [pnpm](https://pnpm.io/9.x/package_json#resolutions)

### Wallet Connection Problems

#### Wallet not connecting

**Solutions:**

1. **Check provider configuration** - Ensure you're passing the correct provider for your account type:

   ```tsx
   // For EVM wallets
   providers={{ evm: window.ethereum }}

   // For Solana wallets
   providers={{ sol: solanaWallet }}

   // For Stellar wallets
   providers={{ stellar: stellarWallet }}

   // For NEAR wallets
   providers={{ near: () => nearWallet }}
   ```
2. **Add the matching network plugin** - For EVM, Solana, and Stellar swaps, you also need to install the relevant sibling package and register its network plugin via the `plugins` property.

   ```tsx
   import { evm } from '@aurora-is-near/intents-swap-widget-evm';
   import { sol } from '@aurora-is-near/intents-swap-widget-solana';
   import { stellar } from '@aurora-is-near/intents-swap-widget-stellar';

   <WidgetConfigProvider
     config={{
       plugins: { evm, sol, stellar },
       // ...
     }}
   >
   ```

Errors like `No EVM transfer configured` mean the plugin is missing:

Note that NEAR is built into widget core and does not need a plugin.

1. **Verify `walletSupportedChains`** - We will attempt to establish the supported chains based on the format of the wallet address, however, you may want to include chains your wallet supports:

   ```tsx
   walletSupportedChains={['eth', 'base', 'arb']}
   ```

### Configuration Errors

#### No styles/broken design

**Cause:** Missing CSS imports.

**Solution:** Import required CSS files:

```tsx
import '@aurora-is-near/intents-swap-widget/styles.css';
```

Check our detailed theming documentation.

#### Tailwind & CSS reset

If you use global CSS reset e.g.:

```css
*, *::before, *::after { box-sizing: border-box; margin: 0; padding: 0; }
```

It will break widget's styles due to Tailwind layering system. If you face that issue and see no paddings, margins or other style issues in a widget please scope your CSS resetting styles with a `@layer base` as below:

```css
@layer base {
  *, *::before, *::after {
    box-sizing: border-box;
    margin: 0;
    padding: 0;
  }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.intents.aurora.dev/intents-swap/widget-configuration/troubleshooting.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
