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 |
DBC’s collect_fee_mode has different values from DAMM v2. DBC: 0 = QuoteToken, 1 = OutputToken. DAMM v2: 0 = BothToken, 1 = OnlyB, 2 = Compounding.
