Usage:

Browser:

// setup client
const web3Provider = new ethers.providers.Web3Provider(window.ethereum);
await web3Provider.current.send('eth_requestAccounts', []);
const signer = ethProvider.current.getSigner();
const contractAddress = '0x......';
const nftClient = EtherOneSyncERC721Client();
await nftClient.connectProvider(contractAddress, web3Provider);
nftClient.connectSigner(signer);
nftClient.setWaitConfirmations(1); // 1 for testnet, 5 for mainnet
// const result = await nftClient.[ERC721 + OnceSync APIs]
