I am trying to sync [crypto.org](http://crypto.org) chain with the wallet address for CDC defi wallet. But it keeps saying “invalid cro address” when I try to sync. I have the checked the address and its correct. I am not sure on how to resolve this. ---

Hey @Raj_V, Did you make sure to follow the instructions in our [CRO integration guide](https://koinly.io/integrations/cro/)? If the issue persists, can you please reach out to our support team on [support@koinly.io](mailto:support@koinly.io)? Please also include the name of the wallet and the address you’ve tried to sync. We’ll then be able to look into our back end and blockchain explorers to verify the address. ---
