  • Listen to all NFT contract transfers tutorial
  • Listen to all events from new contracts specific to a contract factory tutorial
  • Listen to all NFT contracts transfers where sender is a specific address tutorial
  • Listen to all ERC20 contract transfers where sender is a specific address and number of coins transferred is over 1000 tutorial

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" ]
}
