Ethereum-based Dapp development
OpenZeppelin is a blockchain company developing tools and libraries for Ethereum applications. They specialize in secure Solidity coding and utilize proven OpenZeppelin contracts and libraries .
The OpenZeppelin SDK, formerly known as Zeppelin OS, is an Ethereum Dapp development package that provides compilation and deployment capabilities along with standard contracts. It also supports proxy-pattern contracts, enabling the creation of upgradable contracts, allowing developers to more easily develop scalable Dapps.
Recently, the Gas Station Network (GSN) has been introduced, providing a way to popularize Dapps while maintaining the value of decentralization by including a feature (meta transaction) in the SDK that reduces the burden of users' transaction costs .
In this tutorial, we'll explore how upgradeable contracts and GSNs work using the OpenZeppelin SDK. The exercises will be conducted on Windows 10's Windows Subsystem for Linux (Ubuntu 16.04).
Please refer to the link below for the slides.

This is a lecture worth 1 million won~!!!
Thank you for the good review. It seems like 1 million won is the limit. 😂 OpenZeppelin SDK is currently deprecated. To develop an OpenZeppelin upgrade contract, we recommend using Truffle or HardHat's plugin.
