## PDA Derivation

All vault PDAs are derived from the program ID `sVau1tXvayVWfotzm9Ahcv2qfnnfRWttt78BCnNC6dD`:

```typescript theme={null}
import { ExponentVaultsPDA } from "@exponent-labs/exponent-vaults-pda";

const pda = new ExponentVaultsPDA(programId);

// Vault PDA
const [vault] = pda.vault({ seedId });

// LP mint PDA
const [mintLp] = pda.mintLp({ vault });

// LP escrow PDA
const [tokenLpEscrow] = pda.tokenLpEscrow({ vault });

// ExponentPrices PDA
const [exponentPrices] = pda.exponentPrices();
```
