This folder contains a set of example contracts for ink!.
Have a look at the different examples to better understand how to use ink! to build your own Substrate smart contracts.
For building the example smart contracts found in this folder you will need to have cargo-contract
installed.
cargo install cargo-contract --force
We use the --force
to update to the most recent cargo-contract
version.
To build a single example and generate the contracts Wasm file, navigate to the root of the smart contract and run the following command:
cargo contract build
You should now have an optimized <contract-name>.wasm
file, a metadata.json
file and a <contract-name>.contract
file in the target
folder of your contract.
The .contract
file combines the Wasm and metadata into one file and can be used for deployment.
The examples in this folder are released into the public domain. We hope they help you build something great with ink!.
See the LICENSE file in this folder for more details.
