Fair launches on a bonding curve
Every coin starts with the same rules: the full supply on a curve, a price that moves with demand, and graduation to an open market when the curve fills.
A price that moves with demand
There is no order book to fill and no market maker to wait for. Each buy moves the price up the curve and each sell moves it down.
Early buyers pay less because less of the curve is sold
You can always buy or sell against the curve itself

When the curve fills, the coin graduates
Graduation is automatic. Nobody has to approve it and nobody can stop it.
01
The curve fills
Once enough of the curve is sold, the coin reaches its graduation point.
02
Liquidity moves
The curve’s liquidity is added to an open market pool in the same transaction.
03
Open market
The curve closes for good. The coin now trades on the open market like any other.
Simple fees, shared with creators
A small fee on trades, shared with each coin’s creator.

Funds use the same rules, pooled
A fund raises for a set window, then its manager trades the pool on the board. When the fund expires, the pool returns to members by share.
If the raise target is missed, deposits are returned
The manager cannot withdraw the pool
Funds can lose value; results are not promised
Built into every launch
These rules live in the contracts, so no creator can switch them off.
Public by default
Every trade, holder and creator wallet is visible on the board and on chain.
Report a coin
Anyone can report a coin that impersonates a person or brand, or breaks the creator policy.
Creator policy
Coins that impersonate people or brands, or promise returns, are hidden from the board.

Can a coin graduate twice?
No. Graduation happens once. After that the curve is closed and the coin trades on the open market.
What happens if nobody buys?
