Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Are ERC-777 Unsafe?
ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.
- OpenZeppelin is trying to avoid paying a bounty for a vulnerability that caused $1,1B worth of assets freeze
- Security improvements of the ERC20 token standard
- Ethereums most used token standard ERC20 requires security enhancements
- The most used Ethereums token standard (ERC20) requires a security patch.

# Learn: Solidity’s Smart Contract 🤝🏼 by Creating a Will📜!
One of the most common IDE for writing smart contracts is the remix IDE hosted on ethereum.org. This is the fastest way to get started with writing Smart contracts with solidity. It comes with all you need, a web browser-based compiler and about 15 free Ethereum account loaded with 100eth coin. These coins are on the Testnet not the Mainnet so don't even think of spending them🙄.
What are some alternatives?
solmate - Modern, opinionated, and gas optimized building blocks for smart contract development.
hardhat - Hardhat is a development environment to compile, deploy, test, and debug your Ethereum software.
truffle - :warning: The Truffle Suite is being sunset. For information on ongoing support, migration options and FAQs, visit the Consensys blog. Thank you for all the support over the years.
