PrimarySale
import "@thirdweb-dev/contracts/extension/PrimarySale.sol";
PrimarySale lets you set a recipient for any sale value you intend to collect in your smart contract.
Usage
The PrimarySale extension is an abstract contract, and expects you to implement the following functions by yourself:
| Name | Type | Returns | Description |
|---|---|---|---|
_canSetPrimarySaleRecipient | internal view virtual | bool | Runs on every attempt to set a new primary sale recipient. Returns whether this info can be set in the given execution context. |
This is an example smart contract demonstrating how to inherit from this extension and override the functions to add (optional) custom functionality.
