Cross-Chain EVM Requests

All our API methods are supported for cross-chain calls. You only need to specify the chain parameter. For example, this request will query block info on Polygon:

import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

evmApi.block.getBlock({
  blockNumberOrHash: "33000000",
  chain: EvmChain.POLYGON,
});

If no chain is specified, it will, by default, be set to the defaultEvmApiChain, which is set in your config (defaults to "Ethereum mainnet").

Change the Default Chain

To change the default chain, you can specify defaultEvmApiChain in your config:

import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

Moralis.start({
  apiKey: "YOUR_API_KEY",
  defaultEvmApiChain: EvmChain.POLYGON,
});

Moralis.EvmApi.block.getBlock({
  blockNumberOrHash: "33000000",
});

Solana

Change the Default Network

We have two networks for the Solana API, which you can configure similarly. You can specify the mainnet or devnet:

import Moralis from "moralis";
import { SolNetwork } from "@moralisweb3/common-sol-utils";

Moralis.start({
  apiKey: "YOUR_API_KEY",
  defaultSolNetwork: SolNetwork.DEVNET,
});

Moralis.SolApi.account.getBalance({
  address: "ADDRESS",
});
