# DBC Pool Configuration

> Every parameter a DBC launch creator controls — token supply, fees, migration targets, LP distribution, vesting, and post-migration pool settings.

## Overview

A DBC launch is configured via a `PoolConfig` account (the "config key"). The config is created once and can be used to launch many virtual pools from it. All parameters that determine how the launch behaves are set here.

***

## Token Configuration

| Parameter                     | Description                                                 |
| ----------------------------- | ----------------------------------------------------------- |
| `token_decimal`               | Base token decimals (1–9)                                   |
| `token_type`                  | `SplToken` (0) or `Token2022` (1)                           |
| `token_update_authority`      | Whether the creator retains update authority post-migration |
| `fixed_token_supply_flag`     | `0` = dynamic (mint on buy), `1` = fixed (pre-minted)       |
| `pre_migration_token_supply`  | Only for fixed supply — total initial supply                |
| `post_migration_token_supply` | Tokens remaining after migration (for LP + locked)          |
| `leftover_receiver`           | Address to receive leftover tokens (fixed supply only)      |

***

## Fee Configuration

### Trading Fees

Fees are collected in the quote token (`quote_token` mode) or the output token (`output_token` mode):

| `collect_fee_mode` | Value | Description                                       |
| ------------------ | ----- | ------------------------------------------------- |
| `QuoteToken`       | `0`   | Fees always in quote token (SOL/USDC)             |
| `OutputToken`      | `1`   | Fees in whichever token is received by the trader |

<Note>
  DBC's `collect_fee_mode` has different values from DAMM v2. DBC: `0 = QuoteToken`, `1 = OutputToken`. DAMM v2: `0 = BothToken`, `1 = OnlyB`, `2 = Compounding`.
</Note>

### Fee Split

```
Total Trading Fee
  ├── Protocol Fee (20%)
  └── Trading Fee share (80%, split between partner and creator)
```

| Parameter                        | Description                                                   |
| -------------------------------- | ------------------------------------------------------------- |
| `creator_trading_fee_percentage` | Percent of the trading fee share that goes to creator (0–100) |

***

## Migration Configuration

### Migration Target

| `migration_option` | Value | Target             |
| ------------------ | ----- | ------------------ |
| `MeteoraDamm`      | `0`   | Migrate to DAMM v1 |
| `DammV2`           | `1`   | Migrate to DAMM v2 |

### Migration Thresholds

| Parameter                   | Description                                   |
| --------------------------- | --------------------------------------------- |
| `migration_quote_threshold` | Quote reserve level that triggers migration   |
| `migration_base_threshold`  | Base tokens to add to the migrated pool       |
| `migration_sqrt_price`      | Initial price of the post-migration DAMM pool |

### Migration Fee

A one-time fee is deducted at migration. Options:

| `MigrationFeeOption` | Fee                                                       |
| -------------------- | --------------------------------------------------------- |
| `FixedBps25`         | 0.25%                                                     |
| `FixedBps30`         | 0.30%                                                     |
| `FixedBps100`        | 1.00%                                                     |
| `FixedBps200`        | 2.00%                                                     |
| `FixedBps400`        | 4.00%                                                     |
| `FixedBps600`        | 6.00%                                                     |
| `Customizable`       | Custom (set with a separate config for DAMM v2 migration) |

The `migration_fee_percentage` is the total fee percentage taken from migration quote reserves. This total fee is then split between the partner and the creator:

* Partner receives the portion not allocated to the creator
* `creator_migration_fee_percentage` → creator's share of the migration fee

***

## LP Distribution

After migration, the post-migration liquidity is distributed across:

| Bucket     | Parameter                      | Description                            |
| ---------- | ------------------------------ | -------------------------------------- |
| Partner LP | `partner_liquidity_percentage` | % of LP going to the partner/launchpad |
| Creator LP | `creator_liquidity_percentage` | % of LP going to the creator           |

Additionally, a portion of each allocation can be **permanently locked**:

| Parameter                                       | Description                    |
| ----------------------------------------------- | ------------------------------ |
| `partner_permanent_locked_liquidity_percentage` | % of partner LP locked forever |
| `creator_permanent_locked_liquidity_percentage` | % of creator LP locked forever |

### Vesting

The remaining (non-permanently-locked) LP can vest on a schedule:

<Tabs>
  <Tab title="Partner Vesting">
    ```
    partner_liquidity_vesting_info:
      cliff_duration_from_migration_time: 0       // immediate cliff
      frequency: 86400                            // daily releases
      number_of_period: 365                       // over 1 year
      cliff_unlock_amount: <amount>
      amount_per_period: <amount>
    ```
  </Tab>

  <Tab title="Creator Vesting">
    ```
    creator_liquidity_vesting_info:
      cliff_duration_from_migration_time: 2592000 // 30 days cliff
      frequency: 604800                           // weekly releases
      number_of_period: 52                        // over 1 year
      cliff_unlock_amount: <amount>
      amount_per_period: <amount>
    ```
  </Tab>
</Tabs>

## Post-Migration Pool Settings (DAMM v2)

When migrating to DAMM v2, additional parameters control the post-migration pool:

| Parameter                      | Description                                    |
| ------------------------------ | ---------------------------------------------- |
| `migrated_collect_fee_mode`    | Collect fee mode for the DAMM v2 pool          |
| `migrated_dynamic_fee`         | Whether dynamic fee is enabled on DAMM v2 pool |
| `migrated_pool_fee_bps`        | Base fee for the DAMM v2 pool                  |
| `migrated_pool_base_fee_mode`  | Base fee mode for DAMM v2 pool                 |
| `migrated_pool_base_fee_bytes` | Encoded base fee params for the DAMM v2 pool   |

***

## Activation Type

| `activation_type` | Value | Description                        |
| ----------------- | ----- | ---------------------------------- |
| `Slot`            | `0`   | Pool opens at a specific slot      |
| `Timestamp`       | `1`   | Pool opens at a specific timestamp |

Setting `activation_point` to a future slot/timestamp delays all trading until that point.

***

## Pool Creation Fee

| Parameter           | Description                                                |
| ------------------- | ---------------------------------------------------------- |
| `pool_creation_fee` | Lamports charged to create a virtual pool from this config |

This is collected from the pool creator at creation time and distributable via `claimPartnerPoolCreationFee`.
