cryptools-rs

Accounting library for cryptocurrency transaction activity.

It provides a way to measure cryptocurrency activity in one's home currency (the default value is USD, but anything can be used). Reports may be exported as CSV files that reflect income/expense/gains/losses.

The activity that gets imported must be in a prescribed form that effectively looks like this:

txDate	proceeds	memo	1	2	3	4	5
			Bank	Exchange	Exchange	Exchange	Simplewallet
			USD	BTC	BTC	XMR	XMR
			non	non	non	non	non
2/1/16	0	FIRST	-220	0.25
3/1/16	250	SECOND		-0.25		180
4/1/16	0	THIRD				-90	90
5/1/16	0	FOURTH				90	-90
5/2/16	160	FIFTH		0.3		-90
6/1/16	0	SIXTH		-0.3	0.3
7/1/16	200	SEVENTH			0.7	-90
8/1/16	0	EIGHTH		0.5	-0.5
9/1/16	400	NINTH			-0.5	200
10/1/16	900	TENTH		1		-200
11/1/16	0	ELEVENTH		-1.5	1.5
12/1/16	2000	TWELFTH			-1.5	400

CSV file components

• txDate is currently set to parse dates of the format MM/dd/YY.

• proceeds may seem tricky. The way to understand it, since it can apply to any transaction (aside from transfers from one owned-account to another owned-account), is that this is the value transferred in the transaction. For example, if one spends 0.01 BTC for an item at a time when BTC/USD is $10,000/BTC, then the user received value of $100, therefore the proceeds of that transaction would be $100. This field is ignored when the user's home currency is used to purchase cryptocurrency.

• memo is useful for evaluating the final output but isn't important. Currently, commas in the memo are not supported.

After three column of transaction metadata, the Account columns follow.

• Accounts (1, 2, 3, 4, 5, ...): the top row reflects the account number (which currently must start at 1 and increase sequentially). The three other values are the name, ticker, and margin_bool. name and ticker should be self-explanatory. margin_bool is set usually set as 'no', 'non' (i.e., non-margin), or 'false.'
  To indicate a margin account, set it as 'yes', 'margin' or 'true'.

Margin accounts

• Margin accounts must come in pairs, the base account and the quote account. The base account is the coin being longed or shorted, and its ticker is reflected like normal. The quote account is the market. The quote account's ticker requires a different formatting. For example, when using BTC to long XMR, the BTC account must be reflected with the ticker BTC_xmr.

Constraints

• All cryptocurrency-related activity for the user generally must be included in the input CSV file.

• There can only be either one or two accounts used in a given transaction (i.e., if a Counterparty token or Ethereum token transaction must be recorded, the XCP or ETH transaction fee must be reflected in a separate transaction/row).

• Currently, manual adjustments may need to be made to the output files in cases, for example, when the user used cryptocurrency to make atax-deductible charitable contribution.

Installation

1. cargo build (or include --release for a non-debug build)

This will build ./cryptools-rs.
