# DLMM Program Instructions

> Explore DLMM lb_clmm instructions for pool creation, swaps, liquidity, positions, rewards, operators, and limit orders.

The `lb_clmm` IDL exposes many instructions. Integrators can choose to either use the TypeScript SDK for transaction construction or build through CPI.

## Pool Creation

| Instruction                                       | Use                                                                                     |

| `initialize_lb_pair2`                             | Current permissionless v2 pool creation with Token-2022 support and `PresetParameter2`. |
| `initialize_permission_lb_pair`                   | Operator-controlled pool creation for permissioned launches.                            |
| `initialize_customizable_permissionless_lb_pair`  | Legacy customizable permissionless pool creation for SPL Token pools.                   |

## Bin Arrays

| Instruction                             | Use                                                     |

`initialize_bin_array` is compute-heavy. If you construct it manually, add a compute budget instruction.
