Currently smart alert only support to search tokens with nansen label. However, some token are labeled unclearly or have no label. It will be much easier to use if we can search token by contract address.
Like AXS have 2 token contract:
  1. 0xbb0e17ef65f82ab018d8edd776e8dd940327b28b (NEW AXS)
  2. 0xF5D669627376EBd411E34b98F19C868c8ABA5ADA (OLD AXS)
But we can only add NEW AXS to smart alert.
And for Clover:
It is a popular token but without nansen label so we can search it in smart alert.
