Step 1: Setup Moralis

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Report spam ERC20 contracts

In order to run smart contract function, Moralis provides you a contractsReview endpoint to do so.

Here you'll need three parameters: chain, contract_address, and reason.

Once you've obtained chain, contract_address, and reason, you can copy the following code:

index.js (JavaScript)

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");
const abi = require("abi.json");

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const chain = EvmChain.ETHEREUM;

  const contractAddress = "0x06012c8cf97bead5deae237070f9587f8e7a266d";

  const reason = "My Reason";

  const response = await Moralis.EvmApi.utils.reviewContracts(
    {
      chain,
    },
    {
      contracts: [
        {
          reason,
          contractAddress,
          reportType: "spam",
          contractType: "ERC20",
        },
      ],
    }
  );

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

runApp();

index.ts (TypeScript)

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

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const chain = EvmChain.ETHEREUM;

  const contractAddress = "0x06012c8cf97bead5deae237070f9587f8e7a266d";

  const reason = "My Reason";

  const response = await Moralis.EvmApi.utils.reviewContracts(
    {
      chain,
    },
    {
      contracts: [
        {
          reason,
          contractAddress,
          reportType: "spam",
          contractType: "ERC20",
        },
      ],
    }
  );

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

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"

body = {
    "contracts": [
        {
            "contract_address": "0x06012c8cf97bead5deae237070f9587f8e7a266d",
            "reason": "My Reason",
            "report_type": "spam",
            "contract_type": "ERC20"
        }
    ]
}

params = {
    "chain": "eth"
}

result = evm_api.utils.review_contracts(
    api_key=api_key,
    params=params,
    body=body
)

print(result)

Step 3: Run the script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

In your terminal, you should see the following JSON response:

{ "message": "Submission successful" }

Congratulations 🥳 You just report spam ERC20 contracts with just a few lines of code using the Moralis Utils API!
