This page summarizes the
dynamic-bonding-curve account model. For exact layouts, use the published IDL and generated TypeScript types exported by @meteora-ag/dynamic-bonding-curve-sdk.Address Map
| Address | How it is chosen | Use |
|---|---|---|
PoolConfig | New signer account passed to create_config | Partner config for quote mint, fee claimer, leftover receiver, fees, curve, token behavior, migration settings, and graduated-pool settings. |
ConfigWithTransferHook | New signer account passed to create_config_with_transfer_hook | Transfer-hook config. It stores an embedded PoolConfig plus the executable transfer-hook program. |
VirtualPool | PDA from quote mint, base mint, and config | Standard active DBC pool for one base mint and config. Stores pool_state. |
TransferHookPool | Same pool PDA derivation, initialized by initialize_virtual_pool_with_token2022_transfer_hook | Transfer-hook active DBC pool. Stores the same pool_state layout as VirtualPool, with a separate discriminator. |
| Base vault | PDA token account from pool and base mint | Program-controlled token account for launched base tokens. |
| Quote vault | PDA token account from pool and quote mint | Program-controlled token account for quote tokens. |
| Pool authority | PDA from pool_authority | Program authority over vaults and migration flows. The deployed address is FhVo3mqL8PW5pH5U2CN4XE33DokiyZnUwuGpH2hmHLuM. |
| Protocol fee authority | PDA from protocol_fee_authority under the protocol fee program | Fixed signer expected by claim_protocol_fee2, usually through the protocol fee wrapper program. |
| Event authority | PDA from __event_authority | Anchor event-CPI authority required by event-emitting instructions. |
| Partner metadata | PDA from partner_metadata and fee claimer | Optional public metadata for a partner. |
| Virtual pool metadata | PDA from virtual_pool_metadata and pool | Optional public metadata for a pool. |
| DAMM v1 migration metadata | PDA from meteora and pool | Metadata used by DAMM v1 migration and LP lock/claim flows. |
| DAMM v2 migration metadata | PDA from damm_v2 and pool | Deprecated in the program; DAMM v2 migration no longer requires a separate metadata setup step. |
| Operator | PDA from operator | Admin-created permission account for protocol pool creation fee claims and deprecated protocol fee or zap flows. |
| Claim fee operator | PDA from cf_operator | Legacy protocol fee claim authorization account. |

PoolConfig
PoolConfig is the partner-created account that defines all pools launched with a config.
ConfigWithTransferHook embeds the same PoolConfig as config and appends transfer_hook_program. The SDK’s StateService.getPoolConfig returns the embedded PoolConfig for both account variants.
| Field | Use |
|---|---|
quote_mint | Quote mint for every pool using the config. |
fee_claimer | Partner authority allowed to claim partner fees and partner pool creation fees. |
leftover_receiver | Receiver for leftover base tokens after migration for fixed-supply launches. |
pool_fees | BaseFeeConfig and optional DynamicFeeConfig used before migration. |
partner_liquidity_vesting_info, creator_liquidity_vesting_info | DAMM v2 migrated-liquidity vesting settings. |
collect_fee_mode | Whether DBC pre-migration fees are collected in quote token or output token. |
migration_option | Destination AMM: DAMM v1 or DAMM v2. |
activation_type | Whether fee schedules and activation checks use slot or timestamp. |
token_decimal, token_type, quote_token_flag | Base token decimals, base token program, and quote token classification. |
partner_*_liquidity_percentage, creator_*_liquidity_percentage | Permanent locked and claimable liquidity shares after migration. |
migration_fee_option, migration_fee_percentage, creator_migration_fee_percentage | Graduated pool fee key and partner/creator migration fee split. |

sqrt_start_price, curve | Q64.64 start price and fixed array of liquidity distribution points. |
VirtualPool And TransferHookPool
VirtualPool and TransferHookPool are the accounts traders, indexers, and migration keepers read most often.
Both accounts store the active pool fields under pool_state in the IDL and poolState in the TypeScript SDK. Older integrations that read flat fields such as pool.config, pool.baseMint, or pool.quoteReserve must read pool.poolState.config, pool.poolState.baseMint, and pool.poolState.quoteReserve.
| Field | Use |
|---|---|
volatility_tracker | Dynamic fee state: reference price, accumulator, and last update timestamp. |
config | PoolConfig used by the pool. |
creator | Pool creator. This authority can claim creator fees, withdraw creator surplus, and transfer creator rights. |
base_mint, base_vault, quote_vault | Token identity and program-controlled vaults. |
base_reserve, quote_reserve | Current reserves. quote_reserve is the main migration progress input. |
protocol_base_fee, protocol_quote_fee | Accrued protocol trading fees. |
partner_base_fee, partner_quote_fee | Accrued partner trading fees. |
creator_base_fee, creator_quote_fee | Accrued creator trading fees. |
sqrt_price | Current Q64.64 sqrt price. |
activation_point | Slot or timestamp used for fee schedules and rate limiter windows. |
pool_type | SPL Token or Token-2022 base mint. |
is_migrated | Boolean-like migration completion flag. |
