solidity-patterns VS openzeppelin-contracts

Then i delved into best practises (https://consensys.github.io/smart-contract-best-practices/) and patterns (https://fravoll.github.io/solidity-patterns/) to improve.

I recommend using the freecodecamp course(1st one on the list), then going through solidity by examples and the main dedi use cases on https://github.com/smartcontractkit/defi-minimal (if you are interested in more theory, there is https://defi-learning.org/f22) and common design patterns on https://fravoll.github.io/solidity-patterns/

Lets look the events of Open Zeppelin’s ERC20 token contract:

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.
