Hack Wasm Smart Contracts

Read the linked chapters or use tutorials to be able to answer following questions:

Setup ink! Environment Chapter

• Which cargo version are you using?
• Run rustup show command.
• Run cargo contract -V. Is your cargo contract version higher than 1.5.0?
• Which rust toolchain do you need to use to be able to compile ink! smart contrats? (nightly or stable)? How do you manage this choice?

Test Tokens Chapter

• Did you claim Shibuya tokens? How many SBY tokens did the faucet provide to you?
• Can you unit test ink! smart contract without running test node like Swanky-node?

Run Swanky Node

• Start your Swanky node and connect polkadot-JS UI to it. Please note that for Swanky node there will be no node production if there is no interaction with it.

note

Please note that the current version of polkadot-JS is broken for contracts because of lack of support for Weights V2. Until that gets resolved please use our custom built polkadot-JS UI or Contracts-UI.

From Zero to ink Hero Tutorials

Depending on your confidence, use any of these tutorial. If you are just starting, the Flipper contract is the way to go.

• Your task is to deploy the contract from the tutorial to Shibuya Network.
  • After you build contract notice where the .contract and metadata.json are created.
  • Deploy Contract using Contracts-UI.
  • What is the contract address?
  • Do you have any method that requires payment to be executed?
  • Use Polkadot-JS UI to reload same contract you just deployed using Contracts-UI.
