Event Type

Description

ADDRESS_ACTIVITY

Monitors activity for accounts included in a user-defined array of addresses. This event triggers a notification whenever those accounts appear as the sender (from) or recipient (to) of a transaction, ERC20 token transfer, or NFT transfer (ERC721, ERC1155). This service enables real-time tracking of activity across multiple addresses, helping you effectively monitor asset movements and transactions.

TOKEN_TRANSFER

Sends a notification when an ERC20 token transfer or NFT (ERC721, ERC1155) transfer occurs. Specify a contract address to monitor token movements from that contract. For ERC721 and ERC1155 NFTs, you can set a specific token ID as a filter condition to track transfers for that particular token only.

LOG

Sends a notification when a transaction containing the specified smart contract event log is created. One or more event signatures can be set as filter conditions. For example, if you configure monitoring for the Transfer(address,address,uint256) event of the ERC20 standard, all transaction logs matching that event signature (0xddf252ad...) will be captured. Use the LOG event type to efficiently track important on-chain activities such as standard token transfers or specific smart contract events.
