You keep trading on the same coin page. The Buy/Sell button now names the market it uses. Graduated coins trade in a locked DEX pool: Uniswap V4 on BNB Chain and Robinhood Chain, and Meteora on Solana.
The curve fee of 2% stops. The pool charges its own fee instead: 1% on BNB Chain and Robinhood Chain, and 0.25% on Solana. You can also trade a graduated coin on the DEX directly, and those trades show in the market history.
