## Test Results

### CORS Configuration
- Status: $(echo "$CORS_TEST" | grep -q "Access-Control-Allow-Origin" && echo "✅ PASS" || echo "❌ FAIL")
- Headers: $(echo "$CORS_TEST" | grep -i "access-control" | head -3 | tr '\n' ' ')

### API Endpoints

1. **Token Metadata API**
   - cUSDT: $(echo "$TOKEN_METADATA" | grep -q "symbol" && echo "✅ Working" || echo "❌ Failed")
   - cUSDC: $(echo "$TOKEN_METADATA" | grep -q "symbol" && echo "✅ Working" || echo "❌ Failed")

2. **Token Balances API**
   - Status: $(echo "$BALANCES" | grep -q "token\|balance" && echo "✅ Working" || echo "⚠️ Limited")

3. **Transactions API**
   - Status: $(echo "$TXS" | grep -q "hash" && echo "✅ Working" || echo "⚠️ Limited")

4. **Logo URLs**
   - cUSDT Logo: $(curl -s -I "$EXPLORER_URL/images/tokens/$CUSDT_ADDRESS.png" 2>&1 | grep -q "200" && echo "✅ Accessible" || echo "❌ Not Found")
   - cUSDC Logo: $(curl -s -I "$EXPLORER_URL/images/tokens/$CUSDC_ADDRESS.png" 2>&1 | grep -q "200" && echo "✅ Accessible" || echo "❌ Not Found")

## Recommendations

1. Ensure all API endpoints are accessible
2. Verify CORS headers are correctly configured
3. Test from MetaMask Portfolio after deployment
4. Monitor API response times
5. Verify token logos are accessible

## Next Steps

1. Deploy Blockscout with CORS configuration
2. Test from MetaMask Portfolio
3. Verify token auto-detection
4. Verify balance display
5. Verify transaction history
