Based Money

Summary

Based Money launched on Ethereum on August 12, 2020, at the height of DeFi summer, as a self-aware variation on Ampleforth's elastic-supply idea. $BASED targeted 1 sUSD through a rebase that could fire at most once every 24 hours: when a Uniswap v2 oracle read the price more than 5% away from target, supply expanded or contracted across every wallet, smoothed over a ten-day window. Distribution was a fair launch in the YFI mold — no premine, no team allocation, tokens earned by staking into the launch pools. What distinguished Based was its honesty about what rebase tokens actually were that summer: not stablecoins, but a coordination game. Its own community called it a game of chicken — profit by collecting expansion-phase tokens and exiting before sentiment turned, with contractions punishing whoever stayed longest. Activity and price faded with the broader rebase cohort by late 2020, and the project wound down into inactivity.

Design (Mechanism)

The core loop is Ampleforth's: a price oracle, a target, and a supply adjustment applied uniformly to every balance so that holders keep their share of the network rather than a fixed token count. Based narrowed the parameters into something more game-like. The rebase could execute at most once per 24 hours and only when the Uniswap-oracle price deviated more than 5% from 1 sUSD; adjustments smoothed toward target over ten days rather than snapping. Because the schedule was legible, the profitable strategy was too: buy before an expansion rebase, receive newly minted tokens, and sell them into the premium before the next reading — with the losses concentrated on whoever held through the contraction phase.

Distribution reinforced the game framing. There was no allocation to insiders; the supply was earned through launch staking pools, which meant the players and the beneficiaries of the emission schedule were the same people, and the project's value proposition was openly reflexive participation rather than a yield claim.

Outcome

Based rode the August 2020 rebase wave alongside Ampleforth, YAM, and RMPL, and faded with it. The token's price and supply oscillated as designed during the period of attention, but once inflows slowed the expansion phases stopped, contractions dominated, and holders exited. The protocol did not suffer an exploit or a treasury failure; it simply stopped mattering when the game stopped being positive-sum, which is the ending its own "game of chicken" framing predicted. The site and token persist onchain, but development and activity wound down, and the project is best understood as a completed experiment of the 2020 elastic-supply cohort.

Why it worked

• Radical honesty was the marketing: while contemporaries described rebases as stability mechanisms, Based described itself as a game, which attracted exactly the participants such a mechanism actually serves and made the project briefly a cultural centre of DeFi summer.
• The fair launch aligned distribution with participation — every holder had entered through the same public pools, so the emission schedule had no overhang of insiders waiting to exit onto latecomers.
• Constraining the rebase to a known cadence and threshold made the game legible enough to play deliberately, which is what a coordination game needs to attract volume.

Why it failed or underperformed

• An elastic supply targeting a peg does not create demand for the peg; it redistributes tokens between phases of a sentiment cycle. Once net inflows stopped, the mechanism had nothing to stabilise around and contraction became the steady state.
• The legible schedule that made the game playable also made it front-runnable: participants optimising the same known cadence compress the profitable window until only the earliest exits win, which accelerates abandonment.
• Nothing in the design accrued durable value — no revenue, no collateral, no service — so the end of attention was the end of the mechanism.

Lessons

• A rebase changes the unit of account, not the value of a holding; any design whose payoff depends on new entrants arriving each cycle should be analysed as a coordination game with an ending, and Based is the rare case that said so out loud.
• Fair launches align a community but do not sustain one; distribution solves who owns the game, not why the game continues.
• Making a mechanism's schedule fully legible is double-edged: it invites participation and simultaneously invites everyone to optimise against the same clock.

Redesign (EDITORIAL)

EDITORIAL — hypothesis, not fact. A version of this design with more durable behaviour might (1) randomise the rebase timing within a bounded window, as RMPL attempted, so the game cannot be reduced to clock-watching; (2) route a fee on transfers during expansion phases into a reserve that bids under the token during contractions, giving the target something to rest on; (3) cap per-wallet participation in launch pools so the early game is not dominated by the largest stakers; and (4) publish an explicit end condition — a supply band or date at which the experiment concludes and the reserve is distributed — so the game's finite nature is a design feature rather than a discovery.
