# How to play NFT avatars [0]: random mint

I am going to write a series of articles to sharing my experience of NFT avatars.

First one is random mint, cos that’s the most effective way to pass the scams. Project that not random mint can easily reveal top rarity NFTs to themselves, which is a kind of scam IMO.

How to know whether one NFT is random mint:

1\. find the contract address, you can easy find it by opensea url, take 0n1 as example, one of 0n1 opensea url is:

![opensea url of one item for 0n1](https://storage.googleapis.com/papyrus_images/fe9a4f8b1d67e6b1a6d0dcfbb9a8ef8e625097e7ad075fa767dd98691532d491.png)

opensea url of one item for 0n1

2\. remain the contract address and construct the source code url in etherscan:

![on1 contract code](https://storage.googleapis.com/papyrus_images/18a431c3a215ef85db99dcfe46a3039f9fb110427eb1b332d9d816dc6adf8a40.png)

on1 contract code

3\. read contact find the proof of random mint hash, if the hash is empty or the contract has no any property like proof, then it must be not random mint. if the contract provide the proof, go to check the proof in their official website like bayc proof

![0n1 has proof property but the value is empty, which means that they are not random mint](https://storage.googleapis.com/papyrus_images/5696849c329b9d10a425889e82dff9445c2a5da446c8ed50911df558f71d0de2.jpg)

0n1 has proof property but the value is empty, which means that they are not random mint

if the project is random mint like the bayc, it’s contract proof would be like this:

![bayc code has write the proof hash which is proofed in their website](https://storage.googleapis.com/papyrus_images/74a65bee8afab3c443d4a0ce63d55134ee4a1919df0800db930796ee09fafba1.jpg)

bayc code has write the proof hash which is proofed in their website

you can check the proof hash here:

![bayc official website has proof hash cc354bxxxxxx written in the contract ](https://storage.googleapis.com/papyrus_images/562de9a88b7949b127bf3deebdbd674562004b0002b3c90be275439a7d6e2732.jpg)

bayc official website has proof hash cc354bxxxxxx written in the contract

but has no proof doesn’t mean that the project is always bad, but it would help you at least knowing whether the project is random minted or not.
