A stable, audited, and fully tested package for smart contract development
Check out our step-by-step guide to OpenZeppelin-eth, the EVM package implementation of OpenZeppelin 2.0
When we first announced OpenZeppelin in 2016, smart contract security was in a crisis. Major hacks occurred every month, the same logic was being reimplemented again and again, and basic software engineering practices were not being used.
We set out to standardize what secure smart contract code should look like and to provide reference implementations of contracts commonly needed by the community. OpenZeppelin began simply, as a collection of code that was freely available online. However, a community soon formed around it, eager to experiment and build solid smart contract components.
In the two years that followed, we learned together and became a welcoming place for contributors and newcomers. We’re extremely happy with the success that OpenZeppelin has had, and are thankful to everyone that is a part of it.
Experimenting as the ecosystem evolved, the code went through many iterations. In retrospect, some ideas we tried were not the best, but the exploration process pushed important discussions forward. This set the foundations of a healthy community and codebase.
The next step in achieving OpenZeppelin’s mission is to turn the learnings and code from the past two years into a stable and reliable package. To do this, we’re happy to be releasing OpenZeppelin 2.0 with:
