The smart contract is built using ink!, an eDSL to write smart contracts in Rust for Polkadot blockchains built on the Substrate framework.
To compile the smart contract, Rust and Cargo are required. Here is an installation guide.
cargo-contract is required too. Install it using this command:
cargo install cargo-contract --force --lockedTo build the smart contract and generates the optimized WebAssembly bytecode, the metadata and bundles, execute this command:
cargo contract build --releaseTo run the tests off-chain, execute this command:
cargo testOpen the Substrate Contracts-UI.
Choose a chain (E.g. Contracts (Rococo) or Shibuya) in the dropdown placed in the top section of the left menu.
Follow the official ink! guide to upload and instantiate the smart contract.
