No PvP until graduation.
Until a token graduates, any buyer can exit at cost: what you paid, minus the fee and a 2-lamport haircut.
- You paid
- 1.500000000 SOL
- Trading fee
- minus 0.015000000 SOL
- Rounding haircut
- minus 0.000000002 SOL
- Your floor
- 1.484999998 SOL
Refunded from the market's buffer, whatever the price does.
From first buy to graduation
Until graduation, tokens move only through the Trucee router, so nobody can profit off another buyer. Selling is never blocked.
- 1
Buy on the curve
Every buy goes through the Trucee router, which records what you paid. That amount is your cost basis.
- 2
Exit at cost before graduation
Sell back through the router at any time and get your basis back, minus the trading fee and a 2-lamport haircut, from the market's buffer.

Graduate and trade freely
When the curve completes, Meteora DBC revokes the transfer hook and the pool migrates to DAMM v2. Holders split the buffer surplus by basis.
