### POST `/dex/raydium/cpmm/create-unsigned`

  "tokenAmount": "1000000000000",
  "solAmount": "1000000000"
}
```

#### Field notes

* `tokenAmount` is expressed in the token’s **smallest unit** (respecting the mint’s `decimals`).
* `solAmount` is expressed in **lamports** (`1 SOL = 1_000_000_000` lamports).
* The quote mint is Wrapped SOL (`So11111111111111111111111111111111111111112`).

    "quoteMint": "So11111111111111111111111111111111111111112",
    "lpMint": "LpMintAddress...",
    "baseVault": "BaseVaultAddress...",
    "quoteVault": "QuoteVaultAddress..."
  }
}
```
