smart-contract-best-practices 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.

Search for solidity exploits on Google, useful one: https://consensys.github.io/smart-contract-best-practices/ there are a lot of possible exploits so deploying one by yourself without audits is a no-go imo

Consensys' Smart Contract Best Practices is a good start for security related stuff (super important because you'll be dealing with people's money in smart contracts) https://consensys.github.io/smart-contract-best-practices/

The first question which any auditing interview concerns is mostly regarding what is your preferred audit process? Answers could be subjective, but I like to follow the industry standard as in this ‘Solcurity Standard’ article by Rari-Capital along with the Consensys’ best practices set of guidelines which pave a path for a thorough audit process.

Security should always be a major priority when developing smart contracts. Millions of dollars are lost to hackers on what seems like a regular basis. As a Web3 developer, you need to continuously stay up to date on the latest security best practices.

Solidity basics and best practices

Smart Contracts Best Practices

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.

This depends if you're writing a contract from scratch or using existing code. If you're making something new, then yes (recommend not to use THE most recent available, always better to go with tried and tested). For existing projects, never try to override the solidity version. This may be a pain with "@" imports - ideally everyone should specify the library version (e.g. https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v2.5.1/contracts/token/ERC20/ERC20.sol).
