LP Operations

Supported LP operations include:

• Minting liquidity
• Burning liquidity

LP operations use callpath index 2:

userCmd(2, abi.encode(
    code,         // uint8
    base,         // address
    quote,        // address
    poolIdx,      // uint256
    bidTick,      // int24
    askTick,      // int24
    qty,          // uint128
    limitLower,   // uint128
    limitHigher,  // uint128
    settleFlags,  // uint8
    lpConduit     // address
))

The code specifies the type of LP action according to the following codes:

Mint liquidity

• 3 - Fixed in liquidity units
• 31 - Fixed in base tokens
• 32 - Fixed in quote tokens

Burn liquidity

• 4 - Fixed in liquidity units
• 41 - Fixed in base tokens
• 42 - Fixed in quote tokens

The remaining parameters are:

Name	Type	Description
base	address	The address of the base token
quote	address	The address of the quote token
poolIdx	uint256	The index of the pool
bidTick	int24	Will be 0 for full-range liquidity
askTick	int24	Will be 0 for full-range liquidity
qty	uint128	The size of the liquidity being added or removed. Fixed in terms of liquidity units, base token deposit or quote token deposit
limitLower	uint128	The minimum acceptable curve price. If the price of the pool is below this threshold the transaction will revert
limitHigher	uint128	The maximum acceptable curve price. If the price of the pool is above this threshold the transaction will revert
settleFlags	uint8	Flag indicating how user wants to settle the tokens (see Type Conventions)
lpConduit	address	The address of LP token
