Workshop Recap: Setting Up Access Control for Smart Contracts
Access control—that is, “who is allowed to do this thing”—is incredibly important in the world of smart contracts. The access control of your contract may govern who can mint tokens, vote on proposals, freeze transfers, and many other things. It is therefore critical to understand how you implement it, lest someone else steals your whole system.
