Example Flow

Partner will create a unique config key, that includes all configuration for their Dynamic Bonding Curve (DBC) on their platform (e.g. a launchpad).
Creators (users of the platform) can create a token and create a Dynamic Bonding Curve pool using this unique partner config key
Trading platforms (e.g. Jupiter, trading bots) can swap with the Dynamic Bonding Curve pool
When the DBC pool reaches a pre-defined minimum quote threshold, no one can swap with that pool anymore
Meteora's migrator keeper service then migrates the DBC pool by sending a crank to create a new Meteora Dynamic AMM v1 or v2 pool
Upon migration LP tokens are locked by the launchpad, with fees claimable by the partner or creator. This is optional and can be configured as part of the config key.

Key Parameters for configuration

Partner can specify these parameters when they create a configuration on all their pools:

pool_fees: include base_fee and dynamic_fee (optional). Partner can add fee scheduler in base_fee or just a fixed fee. pool_fees defines the trading fee for any pool that is created from this configuration.
collect_fee_mode (0 | 1): 0 means the virtual pool will only collect fee in quote token, 1 means virtual pool will collect fee in both tokens.
migration_option: right now we only support migration to Meteora DAMM, so partner must set the value as 0 for this field.
activation_type (0 | 1): 0 means slot, 1 means timestamp, this field indicates the time unit that pool will work with, mostly in calculating fee scheduler and dynamic fee.
token_type (0 | 1): 0 means SPL Token, 1 means Token2022.
token_decimal: the token decimals that the token will use when user creates the virtual pool with this configuration, we only support token decimals from 6 to 9.
partner_lp_percentage: the percentage of LP that partner can claim after token is migrated.
partner_locked_lp_percentage: the percentage of LP that partner will locked permanently after token is migrated.
creator_lp_percentage: the percentage of LP that creator can claim after token is migrated.
creator_locked_lp_percentage: the percentage of LP that creator will be locked permanently after token is migrated.
migration_quote_threshold: the threhold for quote token, that after virtual pool reserve get such quote token amount, the token will graduate from the launch pool and will be migrated.
fee_claimer: the address of partner that can claim trading fees from the virtual pools as well as fees from the locked LPs.
owner: owner of the configuration.
quote_mint: the quote mint address that virtual pool will support.
migration_fee_option: allow partner to choose a fee option on graduated pool (currently support 0.25% | 0.3% | 1% | 2% | 4% | 6%)
token_supply: when the fields are specified, token will have fixed supply in pre and post migration, leftover will be returned to leftover_receiver (configured in config key)
sqrt_start_price: square root of min price in the bonding curve for the virtual pools.
curve: an array of square price and liquidity, that defines the liquidity distribution for the virtual pools.

Example math to build a simple curve (constant-product) from your parameters

initial base reserve: x tokens (a decimals)
initial quote reserve: y tokens (b decimals) (SOL)
migration threshold: z tokens (SOL)

Calculate price = y * (10^(b-a)) / x (pls keep floating point)
Calculate sqrtStartPrice = floor(sqrt(price) * 2^64) (cut all floating point)
Set maxSqrtPrice = 79226673521066979257578248091
Calculate liquidity:

liquidity = z * 10^b * 2^128 / (maxSqrtPrice - sqrtStartPrice)

Set curve:

curve = [{sqrtPrice: maxSqrtPrice, liquidity=liquidity}]

Post-Migration Graduated Pool Config key

Using the parameter migration_fee_option partners can choose a fee option for the graduated pool.

Pool fees are required and must be valid
Base fee must have a positive cliff fee numerator

Fee Scheduler

when in linear feeSchedulerMode: fee = cliff_fee_numerator - (period * reduction_factor)
when in exponential feeSchedulerMode: fee = cliff_fee_numerator * (1 - reduction_factor/10_000)^period

Fee Mode

Collect fee mode must be either OnlyQuote (0) or Both (1)

Migration and Token Type

For migration to DAMM v1 (MigrationOption: 0), token type must be type SPL (TokenType: 0)

Activation Type

Must be either Slot (0) or Timestamp (1)

Migration Fee

Must be a valid option: FixedBps25 (0), FixedBps30 (1), FixedBps100 (2), FixedBps200 (3), FixedBps400 (4), FixedBps600 (5)

Token Decimals

Must be between 6 and 9

LP Percentages

The sum of partner LP, creator LP, partner locked LP, and creator locked LP percentages must equal 100

Migration Quote Threshold

Must be greater than 0

Price

Square root start price must be within valid range (MIN_SQRT_PRICE to MAX_SQRT_PRICE)

Curve

Must have at least one point and not exceed MAX_CURVE_POINT
First curve point must have sqrt price greater than start price and positive liquidity
Curve points must be in ascending order by sqrt price
All points must have positive liquidity
Last point's sqrt price must not exceed MAX_SQRT_PRICE

Locked Vesting

If not default (all zeros), must have valid frequency and total amount greater than 0

Token Supply

Must be valid in relation to swap base amount, migration base amount, and locked vesting
Post-migration supply must not exceed pre-migration supply
Total required tokens (swap + migration + vesting) must not exceed pre-migration supply
Leftover receiver must be a valid PublicKey (not default/zero address)

Notes

Use createConfig when you understand the bonding curve math and want more customization to the curve structure
Use buildCurveAndCreateConfig when you want to create a curve structure based on percentage of supply on migration and migration quote threshold. We handle the math for you.

    swapBaseForQuote: boolean // Whether to swap base for quote. true = swap base for quote, false = swap quote for base
    poolAddress: PublicKey // The pool address
    referralTokenAccount: PublicKey | null // The referral token account (optional)
}

Returns

A transaction that can be signed and sent to the network.

Example

const transaction = await client.pool.swap({
    owner: new PublicKey('boss1234567890abcdefghijklmnopqrstuvwxyz'),
    amountIn: new BN(1000000000),
    minimumAmountOut: new BN(0),
    swapBaseForQuote: false,
    poolAddress: new PublicKey('abcdefghijklmnopqrstuvwxyz1234567890'),
    referralTokenAccount: null,
})

Notes

The owner must have sufficient balance for the swap.
For SOL swaps, the owner needs additional SOL for transaction fees (approximately 0.01 SOL).
When swapping quote for base (buying tokens), set swapBaseForQuote to false.
When swapping base for quote (selling tokens), set swapBaseForQuote to true.
The minimumAmountOut parameter protects against slippage. Set it to a value slightly lower than the expected output.
The referralTokenAccount parameter is an optional token account. If provided, the referral fee will be applied to the transaction.
If the transaction fails with "insufficient balance", check that you have enough tokens plus fees for the transaction.
The pool address can be derived using client.getDbcPoolAddress(quoteMint, baseMint, config).

swapQuote

Gets the swap quotation between base and quote swaps or quote and base swaps.

Function

swapQuote(swapQuoteParam: SwapQuoteParam): Promise<QuoteResult>

Parameters

interface SwapQuoteParam {
    virtualPool: VirtualPool
    config: PoolConfig
    swapBaseForQuote: boolean
    amountIn: BN
    slippageBps?: number
    hasReferral: boolean
    currentPoint: BN
}

Returns

The quote result of the swap.

Example

const virtualPoolState = await client.getPool(poolAddress)
const poolConfigState = await client.getPoolConfig(virtualPoolState.config)

const quote = await client.pool.swapQuote({
    virtualPool: virtualPoolState, // The virtual pool state
    config: poolConfigState, // The pool config state
    swapBaseForQuote: false, // Whether to swap base for quote
    amountIn: new BN(100000000), // The amount of tokens to swap
    slippageBps: 100, // The slippage in basis points (optional)
    hasReferral: false, // Whether to include a referral fee
    currentPoint: new BN(0), // The current point
})

Notes

The swapBaseForQuote parameter determines the direction of the swap:
- true: Swap base tokens for quote tokens
- false: Swap quote tokens for base tokens
The amountIn is the amount of tokens you want to swap, denominated in the smallest unit and token decimals. (e.g., lamports for SOL).
The slippageBps parameter is the slippage in basis points (optional). This will calculate the minimum amount out based on the slippage.
The hasReferral parameter indicates whether a referral fee should be included in the calculation.
The currentPoint parameter is typically used in cases where the config has applied a fee scheduler. If activationType == 0, then it is current slot. If activationType == 1, then it is the current block timestamp. You can fill in accordingly based on slot or timestamp.
