GameFi death spiral

The mechanism, stated once

A reward currency is minted by play and bought, in practice, by people entering the game. So the currency's price is a function of the arrival rate. When arrivals slow, the price falls; when the price falls, hourly earnings fall; when earnings fall below what a player can get elsewhere, that player stops playing and sells what they hold. Their sale lowers the price further and removes one more source of the demand that was holding it up.

Every stage of that loop is ordinary. What makes it a spiral rather than a correction is that the same variable, the number of people arriving, sits on both sides: it sets the demand for the currency and it sets the supply of players who will mint more of it.

The prediction, dated November 2021

Naavik's deep dive on Axie was published on 12 November 2021, while the game was still growing, and it named the failure in advance. The value of new Axies and SLP was propped up by new players putting fresh money into the game, and if new player growth diminished it could send Axie Infinity into a recession.¹

The report went further than the headline risk. It projected that even with daily active users still growing, a decline in the pace of new monthly additions could reduce total monthly revenue.¹ That is the specific sensitivity founders miss: the economy is exposed to the rate of change in arrivals, not to the level.

The measured decline, with dates

DappRadar and the Blockchain Game Alliance published the on-chain series in April 2022. Axie's activity peaked in January 2022 at over 55,000 daily unique active wallets on average and fell to almost 22,000 by March. The report attributes the start of the decline to mid-February, after Sky Mavis changed the SLP reward ratio to make the in-game currency sustainable over the longer term, and states explicitly that the drop was not wholly a result of the Ronin bridge exploit because activity was already falling.³

The Ronin exploit happened on 29 March 2022, roughly six weeks after the decline began. By October 2022, DappRadar recorded Axie averaging 19,434 daily unique active wallets, a 21% decrease from September.⁴ Peak to that October figure is a fall of roughly 65% in on-chain activity, and the largest single step in it was a reward cut rather than a hack.

The confirmation, dated June 2022

Naavik's follow-up deconstruction, published in June 2022, opened by describing Axie as reeling from a recession prompted by declining player growth and falling token values, with the theft of over half a billion dollars from the Ronin bridge arriving after the initial troubles had begun, followed by a sector-wide crypto crash.²

Two dated analyses by the same firm, seven months apart, describing the same mechanism first as a risk and then as an outcome. That pairing is the reason this failure mode is worth naming: it was legible from the design before it was legible from the charts.

Designing against it

The reward cut is not the villain here, and reading it that way leads teams to the wrong fix. Sky Mavis reduced a faucet that was oversupplying its currency, which was correct. The problem was that in an economy where earnings are the reason to play, correct economic management and a pay cut are the same action.

So the defence has to be built earlier. Model every faucet against a flat player count and a declining one before launch. Size sinks as a proportion of issuance and monitor the ratio weekly rather than reacting to complaints. Fund the reward pool from external revenue where you can, so the payer is a customer rather than the next entrant. And test whether retention survives with the payout set to zero, because if it does not, the reward rate is the product and every future adjustment to it is a market event.
