The following guide will show you how you can spin up a canister smart contract via the NSS front-end dApp. To do so, you need the following:

Once you’ve prepared everything, we can jump right into it.

Log into the NSS front-end dApp via https://nns.ic0.app. Once you’re logged in, navigate to the Canisters tab that you can find at the top on the right-hand side.

In the next step, click on Create or Link Canister and Create New Canister and select your wallet.

The interface will now ask you to enter a given amount of ICP or Cycle. The minimum amount is 2T (2 trillion) Cycles, which includes a fee of 1T Cycles if you create a new canister.
