ARN Client ERC-721 Condition API

The ARN Client Condition API provides convenient methods for checking conditions related to standard ERC721 non-fungible tokens (NFTs) through the arnClient.condition.erc721 API.

Checking Ownership

To check if the connected user owns regular ERC721 NFTs, you can use the isOwnedFrom method. Here's an example:

const myContract = '0x776d77485578e703131b66ef50b1d77f225cc478';
const owns = await arnClient.condition.erc721.isOwnedFrom(myContract);
if (owns) {
  console.log(`The user owns at least one NFT from the required collection`);
} else {
  console.log(`The user does not own any NFT from the required collection`);
}

In the example above, myContract represents the address of the required collection. The method isOwnedFrom checks if the connected user owns any NFTs from the specified collection. If the user owns at least one NFT, it returns true; otherwise, it returns false.

Adding More Details

If you need to be more specific, you can include additional details such as the blockchain network and the minimum count of NFTs required. Here's an example:

const myContract = '0x776d77485578e703131b66ef50b1d77f225cc478';
const minCount = 2;
const myChain = 5; // Goerli
const owns = await arnClient.condition.erc721.isOwnedFrom(myContract, minCount, myChain);
if (owns) {
  console.log(`The user owns at least ${minCount} NFTs from the required collection`);
} else {
  console.log(`The user does not own enough NFTs from the required collection`);
}

In this example, minCount represents the minimum count of NFTs required from the collection, and myChain represents the blockchain network (Goerli in this case). The method isOwnedFrom will check if the connected user owns at least minCount NFTs from the specified collection on the specified blockchain network.

This API is a convenience method built on top of the HasERC721Condition and allows you to benefit from cached results.
