Assignments

1. Read Chapter 7 from “Mastering Ethereum”: https://github.com/ethereumbook/ethereumbook/blob/develop/07smart-contracts-solidity.asciidoc
2. Understand Solidity syntax and semantics implemented in OpenZeppelin’s ERC20 contract: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol
3. Understand Solidity syntax and semantics implemented in OpenZeppelin’s ERC721 (NFT) contract: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol
4. Understand Solidity syntax and semantics implemented in OpenZeppelin’s security-related contracts Ownable, Pausable and ReentrancyGuard: https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/access and https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/security
5. Experiment with the various Solidity concepts using https://remix.ethereum.org/
   
   

Thoughts

• Solidity resembles Java, another a high-level, class-based, object-oriented programming language (according to Wikipedia).
• The devil is in the details it seems: many security implications (i.e. those popping up in Secureum Bootcamp Part 4) are in the technical implementation and its limitations.
• It's hard truly grasping all these nuances by just reading documentatin (yes, yes, there are the hands-on assignments as well). I guess there is only one way forward: P-R-A-C-T-I-C-E 😏.
