How to Track Smart Contract Events in Real Time

const Contract_Factory_ABI = [{
  "anonymous": false,
  "inputs": [
    { "indexed": true, "name": "from", "type": "address" },
    { "indexed": true, "name": "to", "type": "address" },
    { "indexed": true, "name": "contract", "type": "address" },
  ],
  "name": "factoryEvent",
  "type": "event",
}]; // valid abi of the event

const options = {
  chains: [EvmChain.ETHEREUM], // list of blockchains to monitor
  description: "monitor a contract factory", // your description
  tag: "contract_Factory", // give it a tag
  abi: Contract_Factory_ABI,
  includeContractLogs: true,
  allAddresses: true,
  topic0: ["factoryEvent(address,address,address)"], // topic of the event
  webhookUrl: "https://YOUR_WEBHOOK_URL", // webhook url to receive events,
};

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