# Mint

When rolling a snowball, it is essential to 'Start small and grow big'. 

Therefore, users need to pay 0.01 ETH to mint a cold kernel first and then roll the kernel to grow into a giant snowball. 

This kernel is actually[ the owner NFT of an A3S address](/a3s-protocol/a3s-v1.0/what-is-a3s-v1.0.md). It not only acts as a mandatory NFT for participating in the game but also functions as a fully operational NFT-gated smart contract address.

You will be able to view this kernel NFT in your wallet, which includes the following traits:

1. **Token ID**: The sequence of minting this NFT (first minted NFT with the Token ID #1)
2. **A3S Address**: The unique smart contract address that this NFT can control (the address shows on the NFT pic and name)
