Concentrated Pool

Steps to Integration

There are three steps in conducting a create pool: 1) prepare input, 2) approve tokens, 3) conduct create pool. You need to install PiperX sdk and import it to proceed.

import { v3AddLiquidity, v3PositionManagerTokenApproval, v3CreatePool } from '@piperx/sdk/src/core'
import { WIP_ADDRESS } from '@piperx/sdk/src/constant'

Prepare Input

You need the following inputs before you can create a pool

token1_address: address, // if it is $IP native token, use WIP_ADDRESS
token2_address: address, // if it is $IP native token, use WIP_ADDRESS
amount1: bigint, // amount of token 1 you want to deposit to the pool
amount2: bigint, // amount of token 2 you want to deposit to the pool
amount1Min: bigint, // minimal amount of token 1 you want to deposit to the pool
amount2Min: bigint, // minmial amount of token 2 you want to deposit to the pool
initital_price: bigint, 
// initial price for token2 / token1, 
// note that, this is purely token2 amount / token1 amount, so you have to
// convert the decimal beforehand.
tickLower: number, // define the lower range of your liquidity provision priceLower = 1.0001^tickLower
tickUpper: number, // define the upper range of your liquidity provision priceUpper = 1.0001^tickUpper
expire_time: bigint// expiration timestamp for creating the pool
signer: ethers.Signer

Note that, if you are creating pool with $IP token, you should pass in the PiperX wrapped $IP token address, because the $IP token is not a ERC-20 token. For example, if you are create $IP to $USDC pool, please use wrapped $IP address WIP_ADDRESS

Approve tokens

You need to approve the router contract to both your tokens to create this pool

await v3PositionManagerTokenApproval(token1_address, amount1, signer)
await v3PositionManagerTokenApproval(token2_address, amount2, signer)

Creating the pool

await v3CreatePool(token0, token1, fee, initialPrice, signer)
await v3AddLiquidity(
    token1: string,
    token2: string,
    amount1: bigint,
    amount2: bigint,
    amount1Min: bigint,
    amount2Min: bigint,
    tickLower: number,
    tickUpper: number,
    fee: number
    expire_time: bigint,
    signer: ethers.Signer
