Create Pool

For general pool creation, use the create_pool_v2 function in the pool_creator module.

Note that the coin amount must be exactly what you want to deposit. For example, if fix_amount_a is true, the amount of coin A must match the exact amount you want to add.

Function params

• config: the reference of clmm globalconfig object. you can see details at Global config id

• pools: The indexer of all pools.

network	pools object id
mainnet	0xf699e7f2276f5c9a75944b37a0c5b5d9ddfd2471bf6242483b03ab2887d198d0
testnet	0x50eb61dd5928cec5ea04711a2e9b72e5237e79e9fbcd2ce3d5469dc8708e0ee2

• tickSpacing: tick spacing will affect price precision. Now mainnet exist some different type tick_spacing, they correspond to different fee rates.

  tick spacing	fee rate
  2	0.0001 (100)
  10	0.0005 (500)
  20	0.001 (1000)
  60	0.0025 (2500)
  200	0.01 (10000)
  220	0.02 (20000)

• initialize_price: for computational convenience, we use fixed-point numbers to represent square root prices. Use the provided by the SDK transformation price to sqrtPrice: TickMath.priceToSqrtPriceX64() in ts SDK.

• uri: the icon of pool, it's allows null.

• tick_lower_idx: I32 type, it's represents the index of the lower tick boundary.

• tick_upper_idx: I32 type, it's represents the index of the upper tick boundary.

• The tick index must be an integer multiple of tickSpacing. If the provided parameter is not a multiple of tickSpacing, the contract will throw an error.

• -443636 < tickLowerIndex < currentTickIndex<tickUpperIndex < 443636, 443636 is a constant, derived from the maximum range representable by the Q32.62 fixed-point number format.

• Currently, creating a pool requires adding bidirectional liquidity.

• coin_a: The coin A object to add liquidity.

• coin_b: The coin B object to add liquidity.

• metadata_a: The metadata object of coin a.

• metadata_b: The metadata object of coin b.

• fix_amount_a: When adding liquidity, you can select which coin amount to use as the fixed amount. If it's true, use coin a amount, others use coin b amount.

• clock:clock: the sui clock object.

Types:

• coinTypeA: the coin type address about coinA.

• coinTypeB: the coin type address about coinB.
