Concepts

| Concept | Description |
|---|---|
| PDA (Program Derived Address) | Deterministic on-chain account owned by the program — used for the pool, vaults, and whitelist |
| Vault | A PDA that acts as the logical owner for a token’s reserves within the pool |
| Vault Token Account | The SPL token account that actually holds the token reserves for a given vault |
| ATA (Associated Token Account) | A user’s standard token account for a given mint, derived deterministically from their wallet |
| Whitelist | An optional on-chain list of authorized wallet addresses. When enabled, only listed addresses can execute swaps |
| Slippage | The minimum acceptable output amount (min_amount_out). Protects against fee changes between transaction construction and execution |
