Welcome! This is an automated workshop that will on using Solidity Smart contracts. It is aimed at developers who are not familiar with Solidity, or smart contracts.
The workshop has two components:
- An ERC20 token, ticker TD-SOL-101, that is used to keep track of points
- A set of 12 exercises that are able to mint and distribute TD-SOL-101 points
Your objective is to gather as many TD-SOL-101 points as possible. Please note :
- You will need testnet Ether to do this workshop. Lookup "rinkeby testnet faucet" on google.
- The 'transfer' function of TD-SOL-101 has been disabled to encourage you to finish the TD with only one address
- The instructions for each exercice are included in the contracts of each exercice, in contracts/exercices.
- Each exercice contract inherits from the exerciceTemplate, which holds common functions to validate students and credit points
- Each exercice is deployed on the Rinkeby testnet. You can interact with them through MyCrypto, using the contract ABIs in this folder, or through etherscan.
- In order to receive points, you will have to call function that execute code in each smart contract, such that the function
creditStudent(n, msg.sender);is triggered, and distributes n points. - A low level description of what is expected can be inferred by reading the code in each exercice.
