For now, see src/example.ts for examples. Will add examples once stable.

Available functions

Function	Description	Notes
getLbPairs	Get all available LB Pairs
getLbPair	Get a specific LB Pair
findLbPairs	Given a X and Y token mint, find corresponding LB Pair(s). Will also find inverse LB Pairs ie desiredTokenX as tokenY and desiredTokenY as tokenX
getBinsAroundActiveBin	Get current distribution based on a radius around the active bin. Returns price, bin id, x amount and y amount for each bin
getBinsBetweenMinAndMaxPrice	Get bins and corresponding distribution based on a min and max price. Returns price, bin id, x amount and y amount for each bin
getBinsBetweenLowerAndUpperBound	Get bins and corresponding distribution based on a min and max bin ID. Returns price, bin id, x amount and y amount for each bin
getCurrentPrice	Get current price for a LB pair
getPriceOfBinByLbPair	Get price of a bin by its bin id for a LB pair	Prefer getPriceOfBinByBinStep if already have information on bin step to reduce RPC calls
getPriceOfBinByBinStep	Get price of a bin by its bin id given a bin step	Use this when necessary but in general getBinsAroundActiveBin, getBinsBetweenMinAndMaxPrice and getBinsBetweenLowerAndUpperBound would already return the prices for each bin
getBinIdFromPrice	Returns the bin id given a price
getPositionsByUser	Get positions by user pubkey
getPositionsByUserAndLbPair	Get positions by user pubkey for a specific LB Pair
getPosition	Get detailed information for a specific position. information includes binId, price, positionXAmount, positionYAmount etc+
getEqualWeightageAmount	Returns an equal weightage amount of the opposing token based on ratio	This is useful when adding liquidity
initializePositionAndAddLiquidity	Returns a yet-to-be sent Transaction as well as position and positionMint. Use this to construct a transaction to add liquidity to a LB Pair	Note that X and Y distribution values are a percentage (in BPS) of totalX and totalY amount to be deposited. PositionMint will be remove in next iteration.
removeLiquidity	withdraw liquidity from a position
createLbPair	Create a new LB Pair or pool
swap	Works for swaps from X to Y or Y to X. Todo: Handle situation if bin array not yet initialized	If out token account does not exist, will create out token ATA. If out token is SOL, will receive WSOL. Does not handle for WSOL -> SOL
