The raise is 35% full. You take the next 10%, leaving it 45% of the way to graduation. The price before you is 2.05× the first trade, and 2.35× after you. Across that slice you pay about 2.2× on average. If the whole supply were priced along this curve, market cap moves from about 82 SOL to 94 SOL. The trading fee fades with time, so this walk only shows the price.

Brief

The curve is a straight line. The fee starts at 80% and melts to 2% over ten minutes.

The price path is a plain straight climb — the auction is in the fee, not the curve. Buying in the first seconds costs an 80% fee, and the fee falls in even steps to 2% over ten minutes, so every buyer picks their own moment on the way down. It suits a hyped mint where nobody agrees on the opening price and you would rather the market bid the fee down than let bots sweep a cheap open.

Pick this if

You expect a loud open and want price discovery to happen in the fee, not in a wiped-out curve.
You can tell buyers one sentence: the longer you wait, the less fee you pay.

Leave it if

Your buyers are impatient and an 80% opening fee will just scare them off.
You only want the first blocks to be expensive — the two-minute anti-snipe fade is the sharper tool.

How the money moves

If the whole supply were priced at the first trade, the market cap would be about 40 SOL.
At graduation it is about 160 SOL, which is 4× the starting price.
The trading fee opens at 80% and falls in even steps to 2% over 600 seconds. The fee does not add a volatility bump.
Trading fees this config assigns go to the launchpad fee-claimer, not the coin creator.
After graduation, 100% of the LP is permanently locked to the launchpad fee-claimer. It cannot be pulled. The launchpad wallet can update the token name and image.
Mint authority is not left open. Graduation uses Meteora's 1% migration-fee preset.
That slice comes out of the quote before it is paired into DAMM v2.
Launching a pool on this config does not charge an extra creation fee.
