# DAMM v2 Program

At Meteora, we’ve developed a `Node.js <> Typescript SDK`, a `Rust SDK` and a `Go SDK` to make deploying and managing your DAMM v2 liquidity pool easier. The following sections includes information on installing and using the SDKs. It also covers where to find the latest code, and how to contribute to these repositories.

## Compounding Fee Mode

DAMM v2 v0.2.0 introduces a third fee collection mode (`collect_fee_mode = 2`).

| `collect_fee_mode` | Fee Token    | Fee on Input?       |
| ------------------ | ------------ | ------------------- |
| 0 (BothToken)      | Output token | No (fee on output)  |
| 1 (OnlyB)          | Token B      | Only for B→A trades |
| 2 (Compounding)    | Token B      | Only for B→A trades |

In Compounding mode, a percentage of the collected fee (set by `compounding_fee_bps` on the config) is automatically reinvested back into pool reserves rather than accruing to LP positions. This portion is reported as `compounding_fee` in `EvtSwap2`. The remaining claimable portion is reported as `claiming_fee`.

<Note>
  Compounding mode pools use a constant-product formula with no concentrated liquidity range.
