# startDataSync

This function syncs the cache of Carbon DeFi strategies using event data. 

```
ppublic async startDataSync(cachedData?: string)
```

`cachedData` is an optional parameter that will be used to seed the cache, instead of syncing from scratch.

{% hint style="success" %}
Syncing data is required for all trade and data functions, however, it is not a requirement for strategy management.
