HOW IT WORKS

Price is not set by a curve fit to liquidity. It is set by arithmetic. Each rung n costs k·n² — almost free at the bottom, brutal at the top. There is exactly one way up.

PRICE PER RUNG · ETH (k·n²) FULL SWEEP ≈ 100 ETH RAISE

THE LADDER

2,100 fixed-price rungs of 10,000 RUNG each. Send ETH, climb. The wallet that posts the closing transaction for a rung mints its trophy — permanently, on-chain.

THE BOOK

When rung 2,100 closes, the ladder dies and the book opens — and never closes again. EIP-712 signed orders, native ETH settlement, a flat taker fee burned to nothing.

One trophy per rung, minted to whoever lands the closing transaction. Rendered entirely on-chain as SVG — no IPFS, no off-chain host, no expiry. A ledger of who was there.
