CoverPool

Manages cover liquidity positions.

Functions¶

mint¶

    function mint(
        MintParams memory params
    ) external lock

    struct MintParams {
            address to;
            uint128 amount;
            int24 lower;
            int24 claim;
            int24 upper;
            bool zeroForOne;
    }

Mints a Cover LP for the range lower to upper.

lower will be the lower price tick for the position.

upper will be the upper tick for the position.

Both lower and upper must be multiples of the tickSpread for the pool.

claim only need be an exact value in the case the user has already minted a position with the same lower and upper.

If this is the case, the claim tick must be the furthest tick crossed into the position.

zeroForOne as true means the LP deposits token0 and is filled with token1. zeroForOne as false means the LP deposits token1 and is filled with token0.

Parameters:

Name	Type	Description
`to`	int24	The recipient of the fungible position
`lower`	int24	The lower price tick of the range
`claim`	int24	The claim price tick of the range
`upper`	int24	The upper price tick of the range
`amount`	uint128	The amount of the input token to add to the `Position`
`zeroForOne`	bool	`true` for `token0` => `token1` and `false` for `token1` => `token0`

Return Values:

Name	Type	Description
`amount`	uint256	The amount of the input token that was added to mint liquidity.

burn¶

    function burn(
        BurnParams memory params
    ) external lock

    struct BurnParams {
            address to;
            uint128 burnPercent;
            int24 lower;
            int24 claim;
            int24 upper;
            bool zeroForOne;
            bool sync;
    }

Burns liquidity from msg.sender. The token received from the burned liquidity is then sent to the address to.

burnPercent is a number no greater than 1e38 which equals 100%.

lower and upper must match a position owned by the caller.

zeroForOne will be true if the LP is trading token1 for token0 and false if the LP is trading token1 for token0.

sync should be true in most cases to receive the syncFee if available. false should only be used if the user wants to exit their LP without syncing the pool.

Parameters:

Name	Type	Description
`to`	int24	The recipient of the token from the burned liquidity
`burnPercent`	uint128	The percent of the user's liquidity to be burned and collected (1e38 = 100%)
`lower`	int24	The lower price tick of the range
`claim`	int24	The claim price tick of the range
`upper`	int24	The upper price tick of the range
`zeroForOne`	bool	`true` for `token0` => `token1` and `false` for `token1` => `token0`
`zeroForOne`	bool	`true` to allow sync and `false` to skip sync

Return Values:

Name	Type	Description
`amount0`	uint256	The amount of token0 collected for burning liquidity. Matches the value in the callback
`amount1`	uint256	The amount of token1 collected for burning liquidity. Matches the value in the callback

swap¶

    function swap(
        address recipient,
        bool zeroForOne,
        uint256 amountIn,
        uint160 priceLimit
    ) external override lock

Swaps token0 for token1 or token1 for token0.

Parameters:

Name	Type	Description
`recipient`	address	The address to receive the output of the swap
`zeroForOne`	bool	The direction of the swap, true for `token0` => `token1`, false for `token1` => `token0`
`amountIn`	int256	The token amount for the swap
`priceLimit`	uint160	The Q64.96 sqrt price limit. If `zeroForOne` is true, the price cannot be less than this value after the swap. If `zeroForOne` is false, the price cannot be greater than this value after the swap.
`data`	bytes	Raw data being passed through to the callback

quote¶

    function quote(
        address recipient,
        bool zeroForOne,
        uint256 amountIn,
        uint160 priceLimit
    ) external override lock

Swap token0 for token1, or token1 for token0.

Parameters:

Name	Type	Description
`recipient`	address	The address to receive the output of the swap
`zeroForOne`	bool	The direction of the swap, true for `token0` => `token1`, false for `token1` => `token0`
`amountIn`	int256	The token amount for the swap
`priceLimit`	uint160	The Q64.96 sqrt price limit. If `zeroForOne` is true, the price cannot be less than this value after the swap. If `zeroForOne` is false, the price cannot be greater than this value after the swap.
`data`	bytes	Raw data being passed through to the callback

Return Values:

Name	Type	Description
`amount0`	uint128	The change in the pool `token0` balance
`amount1`	uint128	The change in the pool `token1` balance

collectProtocolFees¶

    function protocolFees(
        uint16 syncFee,
        uint16 fillFee,
        bool setFees
    ) external ownerOnly returns (
        uint128 token0Fees,
        uint128 token1Fees
    )

Collect the protocol fees accrued by the pool.

Parameters:

Return Values:
