Getting CLMM Pools

1. Get All Pools

Use sdk.Pool.getPoolsWithPage() method to retrieve all pools.

Parameters

• pagination_args: Default to get all pool lists, supports pagination

Example

async function getAllPools() {
  const pools = await sdk.Pool.getPoolsWithPage()
  console.log(`pool length: ${pools.length}`)
}

2. Batch Get assign Pools

Use sdk.Pool.getAssignPools() method to retrieve specific pools.

Parameters

• assign_pools: An array of pool ID to get.

Example

const pools = await sdk.Pool.getAssignPools(assign_pools)
console.log(pools)

3. Get Single Pool

Use sdk.Pool.getPool() method to retrieve a specific pool.

Parameters

• pool_id: Pool address

• force_refresh: Optional boolean to refresh cache

Example

const pool = await sdk.Pool.getPool(pool_id)
console.log({ pool })

4. Get Pool by Coin Types

Use sdk.Pool.getPoolByCoins() method to find pools by coin types.

Parameters

• coins: Array of coin types

• fee_rate: Optional fee rate number

Example

const coin_type_a = '0x5d4b302506645c37ff133b98c4b50a5ae14841659738d6d733d59d0d217a93bf::coin::COIN'
const coin_type_b = '0xc060006111016b8a020ad5b33834984a437aaa7d3c74c18e09a95d48aceab08c::coin::COIN'

const pools = await sdk.Pool.getPoolByCoins([coin_type_a, coin_type_b])

5. Notes

Some common methods for pool

1. Convert SqrtPrice to Price

Use TickMath.sqrtPriceX64ToPrice() method to convert a given sqrtPrice to a price.

Parameters

• sqrt_price_x64: The sqrtPrice value to convert.

• decimals_a: The number of decimals for coin A.

• decimals_b: The number of decimals for coin B.

Example

const sqrt_price_x64 = '18446744073709551616'
const decimals_a = 6
const decimals_b = 9

const price = TickMath.sqrtPriceX64ToPrice(new BN(sqrt_price_x64), decimals_a, decimals_b)
console.log('Price:', price.toString())
