Introduction

DaLI (Data Loader Interface) is a data loader and input generator for RP2, the privacy-focused, free, non-commercial, open-source, community-driven multi-country cryptocurrency tax calculator: DaLI removes the need to manually prepare RP2 input files. Just like RP2, DaLI is also free, non-commercial, open-source and it prioritizes user privacy by storing crypto transaction data on the user's computer and never sending it anywhere else.

It performs the following operations:

• it reads in crypto transaction information from multiples native sources: CSV files and/or REST-based services;
• it analyzes, processes and merges this data;
• it uses the processed data to generate an ODS input file for RP2 and its respective configuration file.

DaLI has a programmable plugin architecture for data loaders (both CSV and REST-based), pair converters and countries. While some exchanges and wallets are already supported out-of-the-box, more are needed: help us make DaLI a robust open-source, community-driven crypto data loader by contributing plugins for exchanges and wallets! Check open issues or open a new one.

DaLI has unit test coverage to reduce the risk of regression.

Note that DaLI has RP2 as a dependency, so installing DaLI causes RP2 to be installed as well.

IMPORTANT DISCLAIMER:

• DaLI offers no guarantee of correctness (read the license): always verify results with the help of a tax professional.
• The author of DaLI and RP2 is not a tax professional, but has used RP2 and DaLI personally for a few years.

Download

The latest version of DaLI can be downloaded at: https://pypi.org/project/dali-rp2/

Installation

DaLI has been tested on Ubuntu Linux, macOS and Windows 10 but it should work on all systems that have Python version 3.7.0 or greater.

Installation on Ubuntu Linux

Open a terminal window and enter the following commands:

sudo apt-get update
sudo apt-get install python3 python3-pip

Then install DaLI:

pip install dali-rp2

Installation on macOS

First make sure Homebrew is installed, then open a terminal window and enter the following commands:

brew update
brew install python3

Then install DaLI:

pip install dali-rp2

Installation on Windows 10

First make sure Python 3.7 or greater is installed (in the Python installer window be sure to click on "Add Python to PATH"), then open a PowerShell window and enter the following:

pip install dali-rp2

Installation on Other Unix-like Systems

• install python 3.7 or greater
• install pip3
• pip install dali-rp2

Running

DaLI reads in a user-prepared configuration file in INI format, which is used to initialize data loaders and configure DaLI's behavior. The format of the configuration file is described in detail in the configuration file documentation.

An example of a configuration file can be found in test_config.ini.

After processing the configuration file, DaLI reads crypto data from native sources and generates a RP2 input ODS file and a RP2 configuration file in the output directory or where specified with the -o CLI option.

The DaLI executable is country-dependent: dali_<country_code>, where country code is a ISO 3166-1 alpha-2, 2-letter identifier (e.g. dali_us, dali_jp, etc).

Provided DaLI is installed, to generate RP2 input files from the example configuration, open a terminal window (or PowerShell if on Windows).

Create the directory structure and download the example input files using wget or manually.

mkdir -p input

If your system has wget:

wget https://raw.githubusercontent.com/eprbell/dali-rp2/main/config/test_config.ini
wget https://raw.githubusercontent.com/eprbell/dali-rp2/main/input/test_manual_in.csv -P input/
wget https://raw.githubusercontent.com/eprbell/dali-rp2/main/input/test_manual_intra.csv -P input/
wget https://raw.githubusercontent.com/eprbell/dali-rp2/main/input/test_trezor_alice_btc.csv -P input/
wget https://raw.githubusercontent.com/eprbell/dali-rp2/main/input/test_trezor_bob_btc.csv -P input/

If your system doesn't have wget, download the following files manually:

• test_config.ini
• test_manual_in.csv
• test_manual_intra.csv
• test_trezor_alice.csv
• test_trezor_bob.csv

And move the csv files to the input directory:

mv *.csv input

Then generate the US output files for rp2:

dali_us -s -o output -p test_ test_config.ini

• -s option allows DaLI to retrieve spot price information from the Internet, when it's not available from the CSV files or REST endpoints.
• -o option specifies the directory where the ODS output file is generated.
• -p is the prefix of the output file.
• test_config.ini is the configuration that ties the inputs together.

To print command usage information for the dali_us command:

dali_us --help

Finally compute taxes with RP2 using the generated input files (using both FIFO and LIFO accounting methods):

rp2_us -m fifo -o output/ -p rp2_ output/test_crypto_data.config output/test_crypto_data.ods
rp2_us -m lifo -o output/ -p rp2_ output/test_crypto_data.config output/test_crypto_data.ods

0.6.0

• As of RP2 1.3.0, RP2 configuration files are no longer expressed in JSON format: they now use the INI format. So DaLI has been updated to generates INI-format configuration files instead of JSON. Any old JSON-format configuration file can be converted to the new INI format with the following command: rp2_config <json_config>
• added Pionex CSV data loader plugin

0.5.2

• added Binance.com REST data loader plugin
• added Binance.com supplemental (CSV) data loader plugin (for autoinvest purchases and ETH to BETH conversions)

• updated RP2 dependency to latest version, which fixes 2 bugs in HIFO. If you're using HIFO be sure to use RP2 1.10 or better.
• tweaked documentation

0.5.0

• add top-level multi-thread support: it's now possible to run data loader plugins in parallel, using the -t option (which selects the number of parallel threads)
• added Nexo CSV input plugin
• Coinbase REST input plugin: added support for Coinbase Earn Reversals (due to CC refunds, etc.)
• BlockFI CSV input plugin: added new transaction types

• small improvements to code and documentation

0.4.8

• fixed PR #35: added exchange_withdrawal transaction type to Coinbase plugin
• various documentation improvements
• updated RP2 dependency to 1.0.0

0.4.7

• fixed issue #34: sometimes Coinbase returns bad fiat data for crypto conversions (fiat amount of sale < fiat amount of buy). DaLI used to raise an exception: now it issues a warning and sets the fiat fee to 0
• Coinbase plugin: _process_transfer() refactoring

0.4.6

• fixed PRs #31 and #36: various improvements to the logic that reads prices from Web

0.4.5

• Coinbase Pro: fixed a bug which caused the total fiat value (including fee) to be incorrect for certain crypto conversions
• added developer FAQ

0.4.4

• fixed a regression introduced recently: in certain cases, some fees related to conversions would no longer be generated (thus causing small deductions to be ignored)
• added support for USDC: previously it was conflated into fiat and didn't generate a tab, now it does
• Coinbase plugin: added support for fiat_withdrawal and fiat_deposit transactions. They are now tracked internally and no longer cause an unsupported transaction warning
• Coinbase Pro plugin: added support for "conversion" native transactions (these seem to occur when CBPro converts from/to a stable coin)
• minor changes to documentation

0.4.3

• rewrote Coinbase coin swap logic: it now handles correctly swaps from stable coins with a fee (previously it would ignore the fee)
• various documentation fixes and some refactoring

0.4.2

• fixed issue #21: fee-typed out-transactions in the manual plugin would cause an exception
• reviewed all documentation

0.4.1

• minor documentation fixes

0.4.0

• fixed issue #20: Coinbase plugin now supports the staking_reward transaction type
• fix for Coinbase reporting fiat with low precision (only 2 decimal digits): if the value is less than 1c Coinbase rounds it to zero, which caused various computation problems (spot_price, etc.). As a workaround, when this condition is detected the plugin sets affected fields to UNKNOWN or None (depending on their nature), so that they can be filled later by the transaction resolver and RP2

0.3.28

• added threading support to Coinbase Pro
• thread count can now be specified in the plugin configuration section of the .ini file
• additional fix in missing fiat_fee issue in crypto swaps on Coinbase (issue #15)
• updated documentation

0.3.27

• fix for missing fiat_fee issue in crypto swaps on Coinbase (issue #15)

0.3.26

• -s CLI option to read missing spot prices from Web: rewrote implementation from Yahoo Finance (daily granularity) to Coinbase Pro (minute granularity)
• moved cache logic to its own module, so it can be used in multiple places: plugins, transaction_resolver, etc.
• fixed issue #19: the user needs to pass -s to read highly granular price data from Coinbase Pro, when it's missing (or computed as 0)

0.3.25

• merged PR #18: Coinbase plugin wasn't handling crypto conversions correctly and generated negative amounts.

0.3.23

• merged PR #14: in Coinbase Pro plugin crypto fee is now modeled correctly both for buy and sell-side fills
• fixed issue #16: added support for inflation_reward transaction in Coinbase plugin
• added load caching to speed up development (PR #12)
• added parallelism to Coinbase plugin (PR #12)

0.3.22

• fixed issue #16: added support for Coinbase inflation reward transaction
• added error log for unknown transaction type in all plugins, so they are easy to identify and report
• added FAQ on supported exchanges/wallets
• added support for more transaction types in BlockFi plugin (PR #11)

0.3.21

• fixed bug reported in issue https://github.com/eprbell/dali-rp2/issues/10
• fixed from/to_currency detection in Coinbase Pro plugin (PR #9)
• added initial version of developer FAQ document: https://github.com/eprbell/dali-rp2/blob/main/docs/developer_faq.md
• minor fixes to documentation

0.3.20

• fixed a bug in transaction resolver: IN -> IN transaction hint was assigning wrong value to fiat_fee
• fixed a bug in Coinbase plugin: receiving a crypto gift from another Coinbase user generated a transaction with wrong fiat_in_with_fee value
• reworked some of the code to use latest RP2 features: specifically fee-only transactions and crypto_fee in in-transactions. E.g.: Coinbase Pro coin swap code, transaction resolver INTRA -> OUT transaction hint application, etc.
• DaLI output file (the RP2 input file) now has in-transaction crypto_fee. Also updated unit test golden file
• refactored all transaction constructor calls to use keyword arg calling style
• updated setup.cfg dependencies to latest RP2

0.3.19

• Trezor plugin: AM/PM was not parsed correctly in timestamp. Fixed.
• Minor fixes

0.3.18

• fixed a limitation in timestamp processing in Trezor and Trezor Old plugins. The timezone that was passed to the plugin constructor could only be an ISO 8601 format offset: something like "America/Los Angeles" would not be accepted. This caused problems with daylight saving timestamps in Trezor CSV files: daylight savings time would just be ignored, thus causing Trezor summer timestamps to be 1 hour off
• updated input, input/golden, config and docs/configuration_file.md to reflect the above fix
• added pytz stubs

v0.3.17

• added new FAQ on adding support for new wallets and exchanges
• minor fixes

v0.3.16

• major improvements to documentation
• added notes in generated file to describe crypto conversion transactions in Coinbase Pro
• small performance improvement: signature reflexive call is now called only once per class, instead of once per instance

v0.3.6

• template.ods was missing from the final package. Fixed in setup.cfg
• various fixes to documentation

v0.3.4

• First version tracked in change log and uploaded to Github
