Track ERC20 Token Burns and Mints

Lets check all USDC transfers but filter transaction where the recipient or the sender is the zero address and if the amount is greater or equal to 10000 USDC.

Programatically

const transferUsdcAbi = [
  {
    anonymous: false,
    inputs: [
      {
        indexed: true,
        internalType: "address",
        name: "from",
        type: "address",
      },
      {
        indexed: true,
        internalType: "address",
        name: "to",
        type: "address",
      },
      {
        indexed: false,
        internalType: "uint256",
        name: "value",
        type: "uint256",
      },
    ],
    name: "Transfer",
    type: "event",
  },
];

const filter = {
  or: [
    {
      and: [
        { eq: ["sender", "0x00000...00000"] },
        { gte: ["amount", "10000000000"] },
      ],
    },
    {
      and: [
        { eq: ["receiver", "0x00000...00000"] },
        { gte: ["amount", "10000000000"] },
      ],
    },
  ],
}; // we will only receive events when the transfer recipent or the sender is the zero address meaning we are filtering mints and burn

const options = {
  chains: [EvmChain.ETHEREUM], // Monitor USDC on ethereum
  description: "Token burns and mints", // your description
  tag: "mintsAndBurns", // give it a tag
  abi: transferUsdcAbi,
  includeContractLogs: true,
  topic0: ["Transfer(address,address,uint256)"],
  advancedOptions: [
    {
      topic0: "Transfer(address,address,uint256)",
      filter,
      includeNativeTxs: true,
    },
  ],
  webhookUrl: "https://YOUR_WEBHOOK_URL", // webhook url to receive events,
};

const stream = await Moralis.Streams.add(options);

const { id } = stream.toJSON(); // { id: 'YOUR_STREAM_ID', ...stream }

// Attach the contract address to the stream
await Moralis.Streams.addAddress({
  id,
  address: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC address
});

Via WebUI

1. Create a new Stream
2. Fill out the form
3. Switch on Event Emittance and Add the Abi and select the topic
4. Add below value to advanced options

[
  {
    "topic0": "Transfer(address,address,uint256)",
    "filter": {
      "or": [
        {
          "and": [
            { "eq": ["sender", "0x00000...00000"] },
            { "gte": ["amount", "10000000000"] }
          ]
        },
        {
          "and": [
            { "eq": ["receiver", "0x00000...00000"] },
            { "gte": ["amount", "10000000000"] }
          ]
        }
      ]
    }
  }
]
