Exercises

• Week #1

  • Build the English Auction contract with cabal build (you may need to run cabal update first).
  • Clone the The Plutus repository, check out the correct commit as specified in cabal.project.
  • Set-up IOHK binary caches How to set up the IOHK binary caches. "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 module.
  • Fix and complete the code in the Homework2 module.

• Week #3

  • Fix and complete the code in the Homework1 module.
  • Fix and complete the code in the Homework2 module.

• Week #4

  • Write an appropriate EmulatorTrace that uses the payContract contract in the Homework module.
  • Catch errors in the payContract contract in the same module.
