const canSync = dlmmPool.canSyncWithMarketPrice(1.05, activeBin.binId);

if (canSync) {
  console.log('Can sync with market price');
} else {
  console.log('Cannot sync - liquidity exists between current and market price');
}

Notes

The function canSyncWithMarketPrice checks if the pool can sync with a given market price.

isSwapDisabled

Checks if swapping is disabled for a given swap initiator. Function

isSwapDisabled(swapInitiator: PublicKey)

Parameters

swapInitiator: PublicKey      // Address of the swap initiator

Returns Boolean indicating if swap is disabled for the initiator. Example

const isDisabled = dlmmPool.isSwapDisabled(userPublicKey);

if (isDisabled) {
  console.log('Swap is disabled for this user');
} else {
  console.log('Swap is enabled');
}

Notes

Returns true if pair status is disabled
For permissioned pairs, checks activation time and pre-activation settings
Considers special pre-activation swap addresses

Helper Functions

syncWithMarketPrice

Synchronizes the pool with a given market price. Function

async syncWithMarketPrice(
    marketPrice: number, 
    owner: PublicKey
): Promise<Transaction>

Parameters

marketPrice: number           // Market price to sync with
owner: PublicKey              // Owner of the transaction

Returns Transaction for syncing with market price. Example

const syncTx = await dlmmPool.syncWithMarketPrice(1.05, userPublicKey);

Notes

The syncWithMarketPrice function is used to sync the liquidity pool with the market price.

toPricePerLamport

Converts a real price of bin to a lamport value Function

toPricePerLamport(price: number): string

Parameters

price: number                 // Real price to convert

Returns Price per lamport as a string. Example

const pricePerLamport = dlmmPool.toPricePerLamport(1.05);
console.log('Price per lamport:', pricePerLamport);

Notes

The toPricePerLamport function is used to convert a real price of bin to a lamport value.

fromPricePerLamport

Converts a price per lamport value to a real price of bin Function

fromPricePerLamport(pricePerLamport: number): string

Parameters

pricePerLamport: number       // Price per lamport to convert

Returns Real price as a string. Example

const realPrice = dlmmPool.fromPricePerLamport(1050000);
console.log('Real price:', realPrice);

Notes

The fromPricePerLamport function is used to convert a price per lamport value to a real price of bin.
