[chrisli30]

The trigger is an array of Condition, which can be topics, dateRage, etc.
We imply or operator among all conditions.

{ type: "topics"
  value: ["0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef",
           null,
          "0x000000000000000000000000c60e71bd0f2e6d8832fea1a2d56091c48493c788"],
