Usage

batchGetAllTokensByOwner

Specific use case for multicall.

The method batchGetAllTokensByOwner is just a wrapper for method multicall which calls DeploylessNFTViewer with easy interface.

const { DeploylessViewerClient } = require('deployless-viewer')
const { ethers } = require("ethers");

const rpc = "https://mainnet.infura.io/v3/<YOUR_API_KEY>"

async function main () {
  const provider = new ethers.providers.JsonRpcProvider(rpc);
  let d = new DeploylessViewerClient(provider)
  let ret = await d.batchGetAllTokensByOwner('0x7a9fe22691c811ea339d9b73150e6911a5343dca', [
    {
      nftType: 2,
      nft: '0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb'
    }, {
      nftType: 1,
      nft: '0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d'
    }])
  console.log(`ret:`, ret)
}

main()

Accept an array of calls and call them all at once.

If 0x0 is passed as address to call, DeploylessNFTViewer will be called instead.
