Using Antegen

Antegen lets you create simple Ante Tests without writing code! All you need to do is look up a few addresses. Here's how to do it:

NFT balance check test

NFT collection address

To find the address of an NFT collection, go to the collection page on your preferred NFT marketplace and click “View on Etherscan”. (Some NFT marketplaces: OpenSea, SuperRare, Rarible)

In Etherscan, click the “Copy” button by the contract address, then paste this into the "NFT collection address" field.

NFT holder address

From the NFT collection Etherscan page, click on the "Token Tracker" link:

Then select the "Holders" tab to view top holders of that NFT collection:

Minimum balance held

Choose a number between 1 and the number of NFTs from the collection the holder currently holds.

If the holder has fewer than this number of NFTs from the collection, the test will fail.

Token balance check

Token address

Go to Etherscan (or other block explorer for the chain) and select a token.

Under "Other Info", click the Copy icon next to "Token Contract" to copy the contract address.

Token holder address

On the Etherscan page for the token, click the "Holders" tab to view top token holders.

Select one of the addresses and click the Copy icon to copy the holder address.

Minimum balance held

Choose a number between 1 and the current token balance of the holder.

If the holder's token balance drops below this number, the test will fail.
