Triggers

Event-Based Trigger

A trigger event can be passed to advancedUserOperation, in this, a contract address, event signature, and an evaluation statement can be specified.

Contract Address

The address of the contract to listen to the events

Event Signature

The ABI of the event which you wanna trigger the event on

Evaluation Statement

An evaluation statement can be a small mathematical operation, you can use +, -, *, /, <=, >=, and == to calculate or evaluate something from an event. For example in the below snippet event emits reserve0 and reserve1, for this, we can write an evaluation statement like

const evaluationStatement = `:reserve1: / :reserve0: <= ${somerationumber}`;

{
  ...signedUserOp,
  advancedUserOperation: {
    triggerEvent: {
      contractAddress: "0x123",
      eventSignature: "event Sync(uint112 reserve0, uint112 reserve1);",
      evaluationStatement
    }
  }
}

Time-Based Trigger

Transactions can also be sent based on specific time, executionStartWindow and executionEndWindow need to be specified which is compared with the block-time of a chain.

{
    ...signedUserOp,
    executionTimeWindow : {
        executionWindowStart: 12341234,
        executionWindowEnd: 12312123
    }
}
