Exercise 1: Stablecoin
Deploy the oracle smart contract
Call the setEthPrice() function with value 1000 (1 Eth = $ 1000)
Can you trigger the oracle smart contract to set the current price of Ether?
Call the getEthPrice() function
Do you get the provided value as a return from the getEthPrice() function?
Compile and deploy the stablecoin smart contract
Does the smart contract compile and deploy?
Call the registerOracle() function with the address of the oracle smart contract
Call the deposit() function with 1 Ether (in wei)
Call the mint() function with 200 and verify your balance in stablecoin
Have you received the 200 stablecoins?
Call the mint() function with 3000
Does the transaction fail?
Call the withdraw() function with 1 Ether (in wei)
Does the transaction fail?
Call the burn() function with 200
Does you have now 0 stablecoins again?
Mint 500 stablecoins again,
Change the value of ETH in the oracle smart contract to 1
From a second account, deposit 1 Ether, mint 500 stablecoins, and liquidate the position of the first account
Does the liquidation succeed?
Exercise 2: Lending Platform
Deploy the oracle smart contract
Call the setPrice() function with value 1000 and call the getPrice() function
Can you trigger the oracle smart contract to set the price and retrieve the value correctly?
Compile and deploy the tokens smart contract following the script provided.
Does the smart contracts compile and deploy?
Call the registerOracle() function with the address of the oracle smart contract
Call the depositStable() function with 200 Stable and verify your balance in lStable
Have you received the 200 lStable?
With a second user, call depositVolatile with 2'000
Have you received the 2'000 lVolatile?
Call the borrowStable() function with 200
Does the transaction fail?
Call the borrowStable() function with 20
Did you receive the corresponding Stable amount?
Change the value of Volatile in the oracle smart contract to 10
From a second account and liquidate the position of the first account
Does the liquidation succeed?
Exercise 3: Tests and Coverage
Install the test tooling recommended in the documentation
run the command provided in the documentation
Does the tests execute correctly?
Does the tests cover all functions?
For each function, are there two tests, one positive and one negative?
