Troubleshooting

If you're having trouble obtaining testnet tokens:

1. Rate Limits: Most faucets have rate limits. Try different faucets or wait 24 hours before requesting again.
2. Social Authentication: Some faucets require Twitter/GitHub authentication to prevent abuse.
3. Community Resources: Join the VIA Labs Discord to request testnet tokens from the community.
4. Alternative Networks: If one testnet is congested or faucets are depleted, consider using an alternative testnet from our supported networks.
