Standard Pool

Steps to Integration

There are three steps in removing liquidity: 1) prepare input, 2) approve tokens, 3) conduct remove liquidity. You need to install PiperX sdk and import it to proceed.

import { v2RemoveLiquidity, v2RouterTokenApproval } from '@piperx/sdk/src/core'
import { WIP_ADDRESS } from '@piperx/sdk/src/constant'
import { v2ComputeAddress } from '@piperx/sdk/src/constant'

Prepare Input

You need the following inputs before you can remove a liquidity

token1_address: address, // if it is $IP native token, use WIP_ADDRESS
token2_address: address, // if it is $IP native token, use WIP_ADDRESS
liquidity: bigint, // amount of lp token you want to remove to the pool
amount1Min: bigint, // minimal amount of token 1 you want to receive
amount2Min: bigint, // minmial amount of token 2 you want to receive 
expire_time: bigint// expiration timestamp for a swap
signer: ethers.Signer.

Note that, if you are add liquidity for $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 remove from to $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

let lp_token_address = v2ComputeAddress(token1, token2)
await v2RouterTokenApproval(lp_token_address, amount1, signer)

Remove the liquidity

await v2RemoveLiquidity(
    token1: string,
    token2: string,
    liquidity: bigint,
    amount1Min: bigint,
    amount2Min: bigint,
    expire_time: bigint,
    signer
)
