Contract Event

Craft custom filters to receive notifications only when specific conditions are met, ensuring you stay informed without information overload.

Filter Type:

AND: All specified conditions must be met for a notification to trigger.
OR: At least one of the specified conditions must be met for a notification to trigger.

Filters:

Field	Description	Operator	Value
sender	Address sending the transaction triggering the event	==, !=, in, not in, regex	Enter specific address(es) or use patterns
receiver	Address receiving the transaction triggering the event	==, !=, in, not in, regex	Enter specific address(es) or use patterns
blockNumber	Block number where the transaction occurred	==, >, <, >=, <=, !=	Specify the exact block number or use operators for comparisons
blockHash	Unique identifier of the block containing the transaction	==, !=	Enter the specific block hash
transactionHash	Unique identifier of the transaction triggering the event	==, !=	Enter the specific transaction hash
data	Arbitrary data associated with the event	==, !=, regex	Match specific data values or patterns
topic0, topic1, topic2 (optional)	Event-specific topics (indexed parameters)	==, !=, regex	Match specific topic values or patterns (consult contract documentation)
contractAddress	Address of the smart contract emitting the event	==	Enter the specific contract address.

Example:

Assume you're interested in tracking a specific "Transfer" event within a smart contract used for a community token. To receive notifications only when tokens are transferred, set up the following filters:

contractAddress: Enter the smart contract address.
topic0: == "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef" is the topic hash that represents a Transfer(). Can change to other topics or custom events.
topic3: > "0" is an integer greater than 0 which represents the tokenID that is being transferred.

This ensures you're only notified about relevant transfers within the community, allowing you to stay informed about token distribution and community activity.
