EtherRock · interactive mechanism simulation

100 rocks mint one at a time along a quadratic price curve, then trade in a per-item order book with exact-price fills and no slippage guard. Try a fat-finger listing and watch a bot snipe it instantly.

Illustrative simulation. Defaults mirror EtherRock's actual mint (0.001 ETH + 0.001·id² ETH quadratic curve, 100-rock cap, exact-price order book, no royalties) but trade timing and prices are randomized for visualization — not live onchain data. Raise the "mania multiplier" to see 2021-style price mania, or click "Trigger the failure mode" to reproduce the March 2022 incident where a rock listed for 444 wei instead of 444 ETH was sniped by a bot in the same block.
