HNT / IOT Tax 2023 and beyond

Requirements

Export transaction data

Sign up for Hotspotty and add your wallet.

I'm not affiliated with Hotspotty, but I found it is cheapest and easiest for exporting.

Get database tool

Download duckdb command line tool (free).

Open a terminal / command prompt and cd to the folder where you unzipped duckdb (duckdb.exe on Windows).

Run (Mac / Linux):

./duckdb rewards.db

Run (Windows)

./duckdb.exe rewards.db

Get transactions in to database

Export your data in Hotspotty, choosing date range Jan 1 2023 to Jan 1 2024 (we will filter to correct time zone later, this is to ensure we get everything, as Hotspotty uses UTC time).

Download the CSV file, rename it to rewards.csv and move it to where you unzipped the duckdb to.

Import rewards.csv into the database:

CREATE TABLE rewards AS SELECT Token AS token, to_timestamp("Start Date") AS time, Amount AS amount FROM read_csv_auto('rewards.csv');

Filter date to your local time zone (since hotspotty exports in UTC, and duckdb will use your local zone):

DELETE FROM rewards WHERE time < '2023-01-01';
DELETE FROM rewards WHERE time >= '2024-01-01';

Verify which tokens you have:

SELECT distinct(token) FROM rewards;

I will assume you see HNT and IOT in the output, split on those:

CREATE VIEW iot_rewards AS SELECT time, amount FROM rewards WHERE token = 'iot';
CREATE VIEW hnt_rewards AS SELECT time, amount FROM rewards WHERE token = 'hnt';

For a sanity check verify no overlap on the HNT to IOT migration on April 18, 2023:

SELECT max(time) FROM hnt_rewards;
SELECT min(time) FROM iot_rewards;

You should see e.g. 2023-04-18 09:28:25-07 and 2023-04-24 17:00:00-07 (times may vary, dates should be same / close).

Get price data in to database

Download price data:

Move the downloaded HNT-USD.csv and IOT-USD.csv to the same folder as rewards.csv and duckdb.

Import in to database:

CREATE TABLE iot_usd AS SELECT "Date" AS date, ("High" + "Low") / 2 AS price FROM read_csv_auto('IOT-USD.csv');
CREATE TABLE hnt_usd AS SELECT "Date" AS date, ("High" + "Low") / 2 AS price FROM read_csv_auto('HNT-USD.csv');

Join prices with your rewards:

CREATE VIEW iot_usd_rewards AS SELECT time, amount * price AS usd FROM iot_rewards ASOF JOIN iot_usd ON time >= date;
CREATE VIEW hnt_usd_rewards AS SELECT time, amount * price AS usd FROM hnt_rewards ASOF JOIN hnt_usd ON time >= date;

Summarize your rewards in USD:

SELECT sum(usd) FROM iot_usd_rewards;
SELECT sum(usd) FROM hnt_usd_rewards;

Add these two numbers together to get your total rewards in USD in 2023.

You are done.
