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: [
                ['0x6a2C3C4C7169d69A67ae2251c7D765Ac79A4967e', '0xf584F8728B874a6a5c7A8d4d387C9aae9172D621'],
                [1, 4, 137, 80001]
            ],
    }, {
        auth: {
            username: 'Your Project Id',
            password: 'Your Project Server Key',
        }
    });

    console.log(response.data);
})();
