Workshop Recap: Deploying More Efficient Upgradeable Contracts

Upgradeable contracts allow us to alter a smart contract to fix a bug, add additional features, or simply to change the rules enforced by it. Smart contract upgrades can be managed using OpenZeppelin Defender.

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.

Workshop Recap: Service Monitoring and Emergency Response with Defender

The DeFi space, and recently the NFT space, have continued to see a variety of exploits and even insider attacks resulting in vault losses, unexpected liquidations, and fraudulent token mints. OpenZeppelin Defender can help teams detect these types of attacks and abnormal behavior and automatically respond to quickly mitigate the attack.

Workshop Recap: Cheap contract deployment through Clones

Clones (minimal proxies) as described in ERC1167, are very small, and cheap to deploy, smart-contracts that delegate all incoming calls to an implementation (template) contract containing the functionality.
