anyhedge-accountant

Simple tool to retrieve accounting-relevant data for settled anyhedge contracts and output as CSV file

general mode of operation

given either a configured list of payout addresses or a directory with electron cash history export csv files, this tool collects all transactions involving those addresses and checks wether or not they are anyhedge settlement transactions. If so,

  • prefunding tx
  • funding tx
  • payout tx

are all determined and fetched from electrum server. The users side is determined (hedge/long) and the data is output as csv (partial data) and json (full dump).

preparation

  • you'll need node and npm on your system

  • install dependencies using

    #> npm install

  • copy config_example.js to config.js

    #> edit config.js

running

  • #> node anyhedge-accountant.js

output

you will end up with 2 output files:

  • out.json: all the data that was collected
  • out.csv: just a subset of the data (defined in config.js) in tabular form

CAVEAT

The tool currently relies on the following assumptions:

  • first input of funding_tx is from maker (usually the LP), last input of funding_tx is from taker (usually YOU)
  • any change outputs of funding_tx go back to the respective input addresses (puzzling, not sure about this, code removed)

to identify the prefunding_tx

This assumption will likely not hold in the future: GP said they might at some point randomize that order.

CAVEAT2

The concept of a prefunding tx does not always make sense. For example paytaca funds the contract directly from your wallet.

I could remove the whole prefunding_tx, but it might give valuable info for BCHBull users and maybe for manually setup contracts, so I'm leaving it in there. Just be aware prefunding_tx might not always make sense.
