Address Activity - Uniblock Docs

Updates of value and token transfers for the addresses that you track. The Address Activity webhook tracks movement related to specific addresses. It triggers real-time notifications whenever an address sends or receives transactions, providing invaluable insights into token activity and portfolio changes. Address Activity is a custom webhook type offering great flexibility.

Transaction Filter Fields

Field	Description	Operator	Value

receiver	Address receiving the tokens	==, !=, 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
transactionHash	Transaction hash unique to the event	==, !=	Enter the specific transaction hash

Value:

Enter specific values, comma-separated lists for “in” and “not in” operators, or regular expressions for regex matching.

Example: To receive notifications only when your wallet address (0x123abc…) receives tokens from a sender (0x987cdf…), add your wallet address to the addresses and set up the following filter:

sender == 0x987cdf...

This ensures you’re only notified about transfers on your wallet with a specific sender (0x987cdf…).
