Say you have the following topic Transfer(address,address,uint256). You can get every transfer happening on chain by setting the topic to Transfer(address,address,uint256) and setting allAddresses to true. That means you will get all transactions that match this topic. This is not available in all the plans.

Observation: You will also have to provide the ABI, and the events will match only that particular ABI and topic. There are cases when different ABIs have the same topic (for example indexed field can be different for 2 ABIs and the topic will be the same).

Example

The following stream will listen to ALL NFT Transfers, without the need to provide the smart contract address

{
      "tag": "anyEthNFTTransfer",
      "topic0": [ "Transfer(address,address,uint256)" ],
      "allAddresses": true,
      "includeContractLogs": true,
      "abi": [
        {
          "anonymous": false,
          "inputs": [
            {
              "indexed": true,
              "internalType": "address",
              "name": "from",
              "type": "address"
            },
            {
              "indexed": true,
              "internalType": "address",
              "name": "to",
              "type": "address"
            },
            {
              "indexed": true,
              "internalType": "uint256",
              "name": "tokenId",
              "type": "uint256"
            }
          ],
          "name": "Transfer",
          "type": "event"
        }
      ],
      "chainIds": [ "0x1" ]
    }
