How to use Unlock in other contracts
Smart contract developers can easily integrate with Unlock Protocol on-chain, allowing them to limit access to certain features or change the behavior of functions based on membership status!
In this tutorial, we will focus on integrating a Lock itself, rather than the Unlock contract.
Paid only features
The lock contract has multiple functions you could use to assess the membership status of a given address. The most obvious one is called balanceOf
. It will either return 1
if the address owns a valid membership and 0
otherwise (whether the membership has expired, or the address never had one).
Here is an example on how to easily create a contract that has a "members only" feature:
