Wallets get eID-attested for eligibility, then commit funds into a self-hosted public sale contract capped at a fundraising target. When demand exceeds the cap, excess commitments bounce back unfilled — illustrating the Plasma (XPL) sale's ~7x oversubscription.

Illustrative simulation. Defaults loosely mirror the Plasma (XPL) sale on Sonar (~$50M target, ~7x+ oversubscription, sold out in minutes), but wallet arrivals and commitment sizes are randomized for visualization — not live onchain data. Drag the sliders or trigger the FOMO rush to see how a fixed-cap public sale rations demand. Part of The Onchain Experiment Atlas.
