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.

   <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.

   <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:

"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:

"overrides": {
  "valtio": "2.1.7"
}

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

• npm

• yarn

• pnpm

Wallet Connection Problems

Wallet not connecting

Solutions:

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

   // For EVM wallets
   providers={{ evm: window.ethereum }}
   
   // For Solana wallets
   providers={{ sol: solanaWallet }}
   
   // For NEAR wallets
   providers={{ near: () => nearWallet }}

2. 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:

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

Configuration Errors

No styles/broken design

Cause: Missing CSS imports.

Solution: Import required CSS files:

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