Import ABI in TypeScript/JavaScript

import { ethers } from "ethers";
import { iPclAbi } from "@maroo-chain/contracts/abi/precompiles/pcl/IPcl";

const provider = new ethers.JsonRpcProvider("https://rpc.maroo.network");

const pclContract = new ethers.Contract(
  "0x1000000000000000000000000000000000000005",
  iPclAbi,
  provider
);

const admin = await pclContract.policyAdmin();
console.log("Policy Admin:", admin);

// viem example
import { createPublicClient, http, getContract } from "viem";
import { iPclAbi } from "@maroo-chain/contracts/abi/precompiles/pcl/IPcl";

const client = createPublicClient({
  transport: http("https://rpc.maroo.network"),
});

const pclContract = getContract({
  address: "0x1000000000000000000000000000000000000005",
  abi: iPclAbi,
  client,
});

const admin = await pclContract.read.policyAdmin();
console.log("Policy Admin:", admin);
