tend(uint256,int24,int24,int248,uint160)

Solidity

function tend(uint256 totalWeight, int24 newLowerTick, int24 newUpperTick, int248 swapAmount, uint160 sqrtPriceLimitX96) external nonpayable

Details

Internal function to pull funds from pool Update position if necessary, then deposit funds into pool. Reverts if the vault does not own any liquidity or tokens. tick requirements: lowerTick must be lower than upperTick lowerTick must be greater than or equal to the tick min (-887272) upperTick must be less than or equal to the tick max (887272) lowerTick and upperTick must be divisible by the pool tickSpacing-- A 0.05% fee pool has tick spacing of 10, 0.3% has tick spacing 60. And 1% has tick spacing 200.

Parameters

Name	Type	Description
totalWeight	uint256	The share of liquidity we want deposited, multiplied by 10,000. A value of 10,000 means we want to deposit all tokens into uniswap. A value of 0 means we just want all the liquidity out. Note that values above 10,000 are not explicitly prohibited but will generally cause the tend to fail and revert.
newLowerTick	int24	The lower tick of the new position to be created
newUpperTick	int24	The upper tick of the new position to be created. Note that if both are set to the same value, the vault's position will not be updated. Gas will be cheapest if both are set to zero in this case.
swapAmount	int248	The amount to be swapped from one token to another this tend. zeroForOne if positive, oneForZero if negative.
sqrtPriceLimitX96	uint160	The slippage limit of the swap. Protections elsewhere prevent extreme slippage if the keeper calling this function is malicious, but this is the first line of defense against MEV attacks.
