Build your contract

⚠️ Note: This guide supports ink! v5 by default. For experimenting with ink! v6, please refer to our migration guide.

To build your ink! smart contract, make sure you are inside your ink! smart contract directory and run the following command:

cd flipper
pop build

For Pop CLI versions <0.3.0 the pop build command is pop build contract

When you run pop build the default is to build in debug mode which is faster for development. It is important to note that when your contract is ready for production you can build the contract using pop build --release which will create an optimized build ready for production.

You should get output like the following:
