Understanding crosschain_getNFTs

• crosschain_getNFTs is an alternative to getNFTs in which NFTs (ERC-721 tokens) can be retrieved for a given address across multiple different EVM chains in the same query. It takes:
  • Addresses - an array of strings (either one or more account addresses.)
  • Chain IDs - an array of integers.
  • Contracts - (optional) an array of strings. It filters based upon specific collection contracts.

Query example

JavaScript

const axios = require('axios');

(async () => {
    const response = await axios.post('https://rpc.particle.network/evm-chain', {
        chainId: 1,
        jsonrpc: '2.0',
        id: 1,
        method: 'particle_crosschain_getNFTs',
        params: [
