DBC Launch Configuration

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.

Fixed-supply cleanup is covered in DBC Surplus and Leftover.

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.

For the migration flow and liquidity ownership, see DBC Migration and Liquidity. Transfer-hook launches use DAMM v2. The hook is revoked from the base mint when the DBC curve completes, before migrated DAMM v2 liquidity is created.

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.

Bonding-curve fee modes are covered in DBC Fees. Transfer-hook launch behavior is covered in DBC Transfer Hook Pools.
