Crawl from an address

The following command shows how to get the transaction subgraph of an address:

scrapy crawl txs.eth.haircut \
-a source=0xeb31973e0febf3e3d7058234a5ebbae1ab4b8c23 \
-a out=/path/to/output/data \
-a fields=hash,from,to,value,timeStamp,blockNumber,isError,input \
-a types=external,internal
-a min_weight=0.0001

Crawl from multiple addresses

The following command shows how to get the transaction subgraphs of two addresses:

scrapy crawl txs.eth.haircut -a file=/path/to/source/file.json 

Well, the input file file.json is formatted as follow:

[
  {
    "source": "0xeb31973e0febf3e3d7058234a5ebbae1ab4b8c23",
    "types": "external,internal",
    "start_blk": 10933499,
    "out": "/path/to/output/data/0xeb3",
    "min_weight": 0.0001
  },
  {
    "source": "0xc8a65fadf0e0ddaf421f28feab69bf6e2e589963",
    "types": "external,internal",
    "start_blk": 12990635,
    "out": "/path/to/output/data/0xc8a",
    "min_weight": 0.0001
  }
