Fees and curve

There is no bigfish token. No points, no airdrop, no team allocation, nothing to farm. The protocol takes 5% of every trade and that is the entire business model. Everything below is enforced by the contract, not by us.

One curve per profile

The key numbered n costs n² × 0.0001 ETH. Priced in ETH, not dollars: the same key always costs the same amount of ETH.

key	price	to own every key up to it	fee on that key
#2	0.0004 ETH	0.0004 ETH	<0.0001 ETH
#5	0.0025 ETH	0.0054 ETH	0.0003 ETH
#10	0.0100 ETH	0.0384 ETH	0.0013 ETH
#25	0.0625 ETH	0.5524 ETH	0.0081 ETH
#50	0.2500 ETH	4.292 ETH	0.0325 ETH
#100	1.000 ETH	33.835 ETH	0.1300 ETH
#200	4.000 ETH	268.670 ETH	0.5200 ETH

13% per trade, split three ways

the profile

Held by the contract until the person claims, then pushed to their wallet on every trade. If they never show up it keeps accumulating, in their name, forever.

key holders

Split pro rata across every key of that profile at the moment of the trade. Claimable at any time. You earn on other people's trades, never your own.

the protocol

The only revenue bigfish has. No token, no fee switch to flip later, no cut of the reserve.

Both sides pay. A buy and an immediate sell costs about 26% of the curve price. We would rather say it three times than have you find out on your own.

What the contract guarantees

The reserve always covers every key that can be sold. Key #1 is minted free and locked forever, which is what makes that true.
No pause, no upgrade, no proxy, no admin withdrawal of the reserve.
The owner can list profiles and rotate the treasury and signer addresses. That is the entire admin surface.
Anyone can call solvency() on Robinhood Chain and check the contract balance against everything it owes.

What it does not

It does not promise anyone will trade your keys, that a founder will ever claim, or that a key is worth anything. It is a position on a curve with 26% of friction on a round trip, on a market that can stay empty. The risks are listed in full.
