Before getting started building on DBC, you should read the following resource to get a better understanding of how Meteora’s DBC works:

What's DBC?

DBC is Meteora’s first bonding curve pool product that allows you to initialize a virtual reserve pool and migrate to either a DAMM v1 or DAMM v2 pool.

DBC Curve Configs

Each DBC pool is a PDA of token mints + config. A DBC Curve Config Key contains all the settings that will dictate the behavior of your DBC pool, which includes bonding curve shape, pre-graduation fees, post-graduation fees, and more.

​
DBC Program

At Meteora, we’ve developed a Node.js <> Typescript SDK, a Rust SDK and a Go SDK to make deploying and managing your DBC virtual pool easier. The following sections includes information on installing and using the SDKs. It also covers where to find the latest code, and how to contribute to these repositories.

​
Swap Modes

DBC supports two swap instructions:
InstructionModes
swapExactIn only
swap2ExactIn (0), PartialFill (1), ExactOut (2)
swap2 includes additional information in the EvtSwap2 event such as quoteReserveAmount, migrationThreshold, and includedFeeInputAmount.
For pools with Rate Limiter enabled (baseFeeMode == 2), the SYSVAR_INSTRUCTIONS_PUBKEY must be included in the remaining accounts of the swap instruction.

​
Pool Creator Transfer

Pool creators can transfer their creator rights to a new address using the transfer_pool_creator instruction. This transfers all creator privileges including fee claiming rights and surplus withdrawal.

​
Migration

DBC pools can be migrated to either a DAMM v1 or DAMM v2 pool. The DAMM v1 and DAMM v2 pools are both derived from the baseMint, quoteMint and dammConfig.

​
Flow of migration

​
DAMM V1

  1. createDammV1MigrationMetadata
  2. createLocker (if the token has locked vesting)
  3. migrateToDammV1
  4. lockDammV1LpToken (if creatorPermanentLockedLiquidityPercentage or partnerPermanentLockedLiquidityPercentage > 0)
  5. claimDammV1LpToken (if creatorLiquidityPercentage or partnerLiquidityPercentage > 0)

​
Liquidity Vesting (DAMM V2 only)

If partnerLiquidityVestingInfoParams or creatorLiquidityVestingInfoParams are configured, vesting is handled directly via LP positions during migration. No separate migration_metadata account is required.

​
DAMM V2

  1. createLocker (if the token has locked vesting)
  2. migrateToDammV2
DAMM v2 migration now uses positions directly for vesting, removing the need for a separate migration_metadata account. This simplifies the migration flow and reduces the number of accounts and transactions required.

​
DAMM Fee Config Keys

The following section depicts the dammConfig key for each pool type.

​
DAMM v1 Migration Fee Config Keys:

Accessible via DAMM_V1_MIGRATION_FEE_ADDRESS[i] in the DBC Typescript SDK.

​
Migration Keeper

We run 2 migration keepers to automatically migrate DBC pools to DAMM pools.
The Migration Keepers only runs on Mainnet.
Keeper addresses that we are running:
  1. CQdrEsYAxRqkwmpycuTwnMKggr3cr9fqY8Qma4J9TudY
  • pool_config.migration_quote_threshold either requires:
    • 10 SOL
    • 750 USDC
    • 1500 JUP
  1. DeQ8dPv6ReZNQ45NfiWwS5CchWpB2BVq1QMyNV8L2uSW
  • pool_config.migration_quote_threshold requires:
    • >= 750 USD (quote_mint token)

​
Manual Migrator

We have also created a Manual Migrator user interface that allows you to manually migrate your DBC pool to a DAMM pool.
The Manual Migrator runs on both Mainnet and Devnet.
Depending on your DBC Config Key, the migration process will require you to sign more than one transaction to call each instruction.
