ERC721

A standard interface for non-fungible tokens

This section contains the different types of ERC721 methods that can be used in the Unity SDK. For additional operations and methods please refer to the ChainSafe Documentation.​
Balance Of
Counts all ERC721 tokens assigned to an owner
string chain = "cronos";
string network = "mainnet"; // mainnet or testnet
string contract = "CONTRACT_ADDRESS";
string account = "WALLET_ADDRESS";
​
int balance = await ERC721.BalanceOf(chain, network, contract, account);
print(balance);
Owner Of
Find the owner of an ERC721 token
string chain = "cronos";
string network = "mainnet"; // mainnet or testnet
string contract = "CONTRACT_ADDRESS";
string tokenId = "TOKEN_ID";
​
string ownerOf = await ERC721.OwnerOf(chain, network, contract, tokenId);
print(ownerOf);
Owner Of Batch
Balance of batch will get the balance of a list of token ids
string chain = "cronos";
string network = "mainnet"; // mainnet or testnet
string contract = "CONTRACT_ADDRESS";
string[] tokenIds = {"TOKEN_ID", "TOKEN_ID"};
​
List<string> batchOwners = await ERC721.OwnerOfBatch(chain, network, contract, tokenIds);
foreach (string owner in batchOwners)
{
  print ("OwnerOfBatch: " + owner);
}
URI
Returns meta data about the token.
string chain = "cronos";
string network = "mainnet"; // mainnet or testnet
string contract = "CONTRACT_ADDRESS";
string tokenId = "TOKEN_ID";
​
string uri = await ERC721.URI(chain, network, contract, tokenId);
print(uri)
All 721s
Get all 721 tokens from an account
string chain = "cronos";
string network = "mainnet"; // mainnet or testnet
string account = "WALLET_ADDRESS";
string contract = "";
int first = 500;
int skip = 0;
string response = await EVM.AllErc721(chain, network, account, contract, first, skip);
print(response);
