### Launch Checklist

1. Change all environment URLs from `staging.crossmint.com/api/2022-06-09` to `www.crossmint.com/api/2022-06-09`.
2. Change your API keys to the production versions. *Ensure your production API key has the appropriate scopes enabled, such as `orders.create`, and that all authorized domains and mobile bundle identifiers are properly configured.*
3. Update your collection ID to the production one.
4. As needed, change your passed-in props to be production ready (e.g. email, `payment`, `lineItems`).
