On Sunday May 2nd, 2021, the Fei Labs team identified an economic vulnerability that affected the Fei Protocol, which would have allowed an attacker to drain funds from the ETH-FEI Uniswap pool. The team immediately paused the relevant functionality, and no funds were lost. The Fei team reached out to the OpenZeppelin team, and we worked together to ensure a secure fix for the issue was found.

This new release introduces UUPS proxies as a cheaper alternative to Transparent proxies. Additionally, a new ERC20 extension allows easy creation of tokens with built-in flash minting, and a new small utility contract provides a function batching mechanism that requires no extra work to set up.

Contracts Wizard is an interface to interactively build a contract out of components from OpenZeppelin Contracts. Select the kind of contract that you want (current support for ERC20 and ERC721), set your parameters and desired features (token name, symbol, premint amount, access control, etc.), and Wizard will generate all of the code necessary.
