DBC configs are reusable launch templates. The curve defines price discovery; the surrounding config defines which token can launch, how fees behave, how migration works, and who can claim each economic bucket.
Use this page as a checklist. For implementation limits and permissions, see DBC Accounts and Permissions.
Core Fields
| Field | Program Behavior |
|---|
| Quote mint | Must be supported. SPL Token quote mints are supported; Token 2022 quote mints are limited to metadata-related extensions. |
| Activation type | Slot-based or timestamp-based. Fee schedules and rate limiter windows use the same activation type. |
| Token decimals | Must be from 6 to 9. |
| Token type | SPL Token or Token 2022. Token 2022 launches must use DAMM v2 migration. |
| Token authority option | Controls whether creator, partner, or no one receives update authority, and whether creator or partner receives mint authority. |
| Transfer hook program | Optional Token 2022 transfer-hook path. Use a ConfigWithTransferHook; the program must be executable and cannot be DBC, SPL Token, Token 2022, or the default pubkey. |
| Collect fee mode | QuoteToken or OutputToken for bonding-curve trading. |
Mint-authority token authority options are only valid for transfer-hook configs. Standard configs reject CreatorUpdateAndMintAuthority and PartnerUpdateAndMintAuthority.
Supply
DBC supports dynamic supply and fixed supply.
| Supply Model | Program Behavior |
|---|
| Dynamic supply | Initial base supply is calculated from the curve swap amount with a 25% buffer, migration base threshold, and locked-vesting amount. |
| Fixed supply | Config provides pre-migration and post-migration supply. The leftover receiver must be non-default, and pre-migration supply must cover the buffered requirement. |
Migration
| Setting | Program Behavior |
|---|
| Migration target | DAMM v1 or DAMM v2. DAMM v1 is restricted to SPL Token base and quote mints. |
| Migration fee option | Fixed DAMM fee options or Customizable for custom DAMM v2 migrated-pool fee settings. |
| Migration fee percentage | Up to 99%. If it is 0, creator migration fee percentage must also be 0. |
| DAMM v2 migrated pool fee | Must be 0.1% to 10% when custom migrated-pool fees are configured. |
| DAMM v2 compounding fee bps | Must be non-zero only for compounding migrated-pool collect fee mode. |
| DAMM v2 market-cap scheduler params | Apply after migration; they do not affect the DBC bonding-curve fee. |
Liquidity Distribution
The migrated liquidity distribution must add to 100% across:
- Partner unlocked liquidity.
- Partner permanent locked liquidity.
- Partner vesting liquidity.
- Creator unlocked liquidity.
- Creator permanent locked liquidity.
- Creator vesting liquidity.
At least 10% of migrated liquidity must still be locked after one day. DAMM v2 vesting lock duration is capped at two years.
Fees and Claim Addresses
| Setting | Program Behavior |
|---|
| Pool creation fee | Optional. If non-zero, must be between 0.001 SOL and 100 SOL; split 10% protocol and 90% partner. |
| Creator trading fee percentage | Splits the non-protocol trading fee between creator and partner. |
| Fee claimer | Authorizes partner-side claims such as trading fees, pool creation fees, migration fees, and surplus. |
| Leftover receiver | Receives fixed-supply leftover after the migrated pool reaches CreatedPool. |
| First swap with minimum fee | Optional narrow path for an initialize-pool transaction that includes the first swap, targets that new pool, and has no referral account. |
