brownie VS smart-contract-best-practices

Check out Brownie if you are familiar with python https://github.com/eth-brownie/brownie

If you are going to use Brownie in this challenge, in your virtual environment, go ahead and install Brownie, after you installed it, create a new folder called nft and inside it run the following command:

Python and Brownie ETH, or any smart contract framework

Web3.py and Brownie setup, testing and deployment

One more advice - try executing the swaps in javascript/nodejs (https://github.com/ethers-io/ethers.js/) or python (https://github.com/eth-brownie/brownie) first, can be easier to learn. Then move it into a smart contract.

Check out ETH-Brownie first of all, you're going to love it if you're a Python guy. The docs are great.

For python backend development, I really like this tool, eth-brownie.

Take a look at Brownie https://github.com/eth-brownie/brownie

For someone coming from Python, Vyper would be easier to learn. There is some learning material to help you start, but for more advanced concepts it might be harder to find. And some of Ethereum tools (for security, for monitoring) are built for Solidity, but in the last couple of months some of them started to include more Vyper support. And to test your contracts, and a basis dev environnement for Vyper, Brownie (https://github.com/eth-brownie/brownie) might be the best choice, since it's Python based

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.
