## Type Declaration

| Name | Type | Description | Defined in | | --- | --- | --- | --- | | `defaultConnectionRequirement?` | [`ConnectionRequirement`](../../enumerations/ConnectionRequirement/) | It can be annoying to set `connectionRequirement` on every building block in a Pack. Use this setting in your Pack's auth settings to quickly say "every building block in this Pack requires an account". Without a connectionRequirement, building blocks will be assumed to not need account connections. | [api_types.ts:714](https://github.com/coda/packs-sdk/blob/853bf0fabbc842fea7362510b545440b16a96b05/api_types.ts#L714) |
