Event Advanced extends the Event Emitted trigger in two key ways: the event is identified by a free-text signature search rather than a dropdown selection, and it can watch any contract address — not just the one you are monitoring. Use this when you need to react to events emitted by external contracts (e.g., a DEX, oracle, or bridge) in the context of your monitored entity.

Use cases

Monitor an oracle or price feed contract for its AnswerUpdated event and react within the context of your monitored contract.
Watch for Swap or Sync events on a Uniswap pair contract that is related to your token, even though it is a third-party contract.
Detect cross-chain message events emitted by a bridge contract to correlate with activity on your monitored contract.

Configuration

1

Trigger Name

Enter a descriptive label, e.g. Oracle Price Updated.
2

Event

Search for the event by name or by its keccak-256 signature hash. Unlike Event Emitted, this field accepts free-text input and is not limited to the monitored contract’s ABI.
Search methodExample
By nameTransfer — matches Transfer(address,address,uint256)
By signature hash0xe1fffcc4923d04b559f4d29a8bfc6cda04eb5b0d3c460751c2402c5c5cc9109c
Use the signature hash when the event name is ambiguous or when you know the exact topic0 from a transaction receipt.
3

Event Address

Enter the address of the contract that will emit the event. This can be any contract on the same network — it does not have to be the monitored contract.
4

Severity

Choose the alert severity: Critical, High, Medium, Low, or Info.
5

Notification Channels

Select one or more channels to receive the alert.
Use Event Emitted when you want to watch an event on the contract you are already monitoring. Use Event Advanced when the event source is a different contract address.
