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.

Blockchain transactions decoding: making wallet activity understandable
We will look at best examples of how popular web3 products (wallets, portfolio trackers etc.) visualize complex wallet activity information, and then we will implement on typescript the logic responsible for preparing data for such visualization (github repository with code).

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.
