### 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;
  }
}
```
