Airdrop farming, honestly
By the end of this lesson you can
- →Build the full expected value model including capital, gas, time and tax at receipt
- →Compute the effective hourly rate a campaign paid, rather than its headline

This lesson opens with The Arbitrum airdrop, 23 March 2023.
- What happened
- Arbitrum distributed 1.162 billion ARB, being 11.62 percent of a ten billion supply, across 625,143 eligible addresses. The median allocation was 1,250 ARB, with more than 245,000 addresses falling in that band, and the token traded a little above $1.30 at the claim. Eligibility used activity criteria plus sybil filtering, including disqualification of addresses identified through Hop Protocol's bounty program and graph-based clustering to detect coordinated wallets. Subsequent research nevertheless identified 96,755 sybil addresses within the eligible list, which collectively received 164,153,951 ARB.
- The decision point
- This was among the most generous and best-executed distributions in the sector's history, and the median recipient received about $1,625 before tax. Run that against the cost of qualifying and the result is close to zero and frequently negative, which is not a criticism of the distribution. It is what the arithmetic says about the activity. And the identified sybil addresses averaged more per address than the median honest participant, because eligibility was a filter and a filter is something you can optimize for directly.
What you will be able to answer
- →What are the four cost lines in an airdrop model?
- →What did the median Arbitrum recipient net?
- →What flips the result?
- →Why did identified sybils outperform the median?
Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.
It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested
Sybil counts come from third-party analyses using clustering heuristics rather than from the distributing protocol, and different researchers reach different totals. Marked medium confidence. The direction is consistent across analyses and the lesson uses the comparison rather than the absolute number.
J305-04 covers what a point is as an instrument and the wrapper risk of holding one, and defers this model here. Tax treatment varies by jurisdiction and the ordinary-income-at-receipt assumption follows F108. Both should be read alongside this lesson rather than in place of it.
