anyhedge-accountant

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

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 (short/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.

CAVEAT3

Due to limiations of the underlying generalprotocols anyhedge parser implementation, this software detects and outputs info for exactly one anyhedge version. There are also some naming changes between those parser versions (hedgePayout -> shortPayout) so it's not an easy feat to make it work for all version.

Suggestion is to use an older version of anyhedge-accountant for older anyhedge contracts (and keep the output files for each version (I'm encoding the anyhedge version into the filename myself) to import into your accounting)

You can check which version is used by looking at the version of @generalprotocols/anyhedge in package.json

• @generalprotocols/anyhedge 1.x.y: anyhedge v0.11
• @generalprotocols/anyhedge 2.x.y: anyhedge v0.12
