Circle · interactive mechanism simulation

Fair-launched on a bare Uniswap v2 pool (full supply vs. 1 ETH, no tax) — every buy/sell moves the pool price, and the onchain circle's radius is a live function of market cap. Edit the parameters and watch it grow or shrink.

Illustrative simulation. Circle fair-launched its full supply against 1 ETH on a Uniswap v2 fork on Shape with no buy/sell tax, opening market cap ~$5,000; the onchain artwork's radius tracked market cap directly. Trade sizes, holder counts and timing here are randomized for visualization — not live onchain data. The “simulate sell-off” button illustrates that, by design, the mechanism has no tax, fee sink, or floor support to cushion a dump. Part of The Onchain Experiment Atlas.
