# Trading on Solana

> Read curve execution, slippage, fees, and the switch to Raydium.

Before migration, KEK.PRO is the market maker. Buys remove tokens from the
curve and add SOL; sells return tokens and remove SOL.

## Curve execution

The curve follows constant-product reserve math. Larger orders move further
along the curve, so price impact grows with size.

Before signing, check:

* expected output and minimum received;
* price impact and slippage;
* real SOL reserves and migration progress;
* the token address;
* the active venue.

A single buy cannot exceed `100 SOL`. This is a protocol constant, not a UI
preset.

## Fees

The reviewed curve defaults charge `0.05%` to the protocol and `0.05%` to fee
rights, for `0.10%` total. A referral share, when active, comes out of the
protocol fee rather than adding another charge.

See [protocol fees on Solana](/solana/fees) for the full breakdown.

## Venue switch

| State             | Execution             |
| ----------------- | --------------------- |
| Curve active      | KEK.PRO bonding curve |
| Migration pending | Curve trading paused  |
| Migrated          | Raydium CPMM          |

Refresh the quote when the lifecycle changes. A curve quote cannot execute
after migration.
