## Exercises

- Week #1

  - Build the [English Auction](code/week01) contract with `cabal build` (you may need to run `cabal update` first).
  - Clone the [The Plutus repository](https://github.com/input-output-hk/plutus), check out the correct commit
    as specified in [cabal.project](code/week01/cabal.project).
  - Set-up IOHK binary caches [How to set up the IOHK binary caches](https://github.com/input-output-hk/plutus#iohk-binary-cache). "If you do not do this, you will end up building GHC, which takes several hours. If you find yourself building GHC, STOP and fix the cache."
  - Enter a `nix-shell`.
  - Go to the `plutus-playground-client` folder.
  - Start the Playground server with `plutus-playground-server`.
  - Start the Playground client (in another `nix-shell`) with `npm run start`.
  - Copy-paste the auction contract into the Playground editor - don't forget to remove the module header!
  - Compile.
  - Simulate various auction scenarios.

- Week #2

  - Fix and complete the code in the [Homework1](code/week02/src/Week02/Homework1.hs) module.
  - Fix and complete the code in the [Homework2](code/week02/src/Week02/Homework2.hs) module.

- Week #3

  - Fix and complete the code in the [Homework1](code/week03/src/Week03/Homework1.hs) module.
  - Fix and complete the code in the [Homework2](code/week03/src/Week03/Homework2.hs) module.

- Week #4

  - Write an appropriate `EmulatorTrace` that uses the `payContract` contract in the [Homework](code/week04/src/Week04/Homework.hs) module.
  - Catch errors in the `payContract` contract in the same module.

- Week #5

  - Add a deadline to the minting policy in the [Homework1](code/week05/src/Week05/Homework1.hs) module.
  - Fix the token name to the empty `ByteString` in the NFT contract in the [Homework2](code/week05/src/Week05/Homework2.hs) module.

- Week #6

  - Get the Oracle demo running and extend it in some way.

- Week #7

  - Implement the game of "Rock, Paper, Scissors" using state machines.

- Week #8

  - Add a new operation `close` to the `TokenSale`-contract that allows the seller to close the contract and
    retrieve all remaining funds (including the NFT).
  - Modify the tests accordingly.
