IQuoterV2

QuoterV2 Interface Supports quoting the calculated amounts from exact input or exact output swaps. For each pool also tells you the number of initialized ticks crossed and the sqrt price of the pool after the swap. Developer note: These functions are not marked view because they rely on calling non-view functions and reverting to compute the result. They are also not gas efficient and should not be called on-chain.

Functions

quoteExactInput

quoteExactInput(bytes,uint256) external

Returns the amount out received for a given exact input swap without executing the swap

Name	Type	Description
path	bytes	The path of the swap, i.e. each token pair
amountIn	uint256	The amount of the first token to swap

Returns:

Name	Type	Description
amountOut	uint256
sqrtPriceX96AfterList	uint160[]
initializedTicksCrossedList	uint32[]
gasEstimate	uint256

quoteExactInputSingle

quoteExactInputSingle(struct IQuoterV2.QuoteExactInputSingleParams) external

Returns the amount out received for a given exact input but for a swap of a single pool

Name	Type	Description
params	struct IQuoterV2.QuoteExactInputSingleParams	The params for the quote, encoded as `QuoteExactInputSingleParams` tokenIn The token being swapped in tokenOut The token being swapped out amountIn The desired input amount limitSqrtPrice The price limit of the pool that cannot be exceeded by the swap

Returns:

Name	Type	Description
amountOut	uint256
sqrtPriceX96After	uint160
initializedTicksCrossed	uint32
gasEstimate	uint256

quoteExactOutput

quoteExactOutput(bytes,uint256) external

Returns the amount in required for a given exact output swap without executing the swap

Name	Type	Description
path	bytes	The path of the swap, i.e. each token pair. Path must be provided in reverse order
amountOut	uint256	The amount of the last token to receive

Returns:

Name	Type	Description
amountIn	uint256
sqrtPriceX96AfterList	uint160[]
initializedTicksCrossedList	uint32[]
gasEstimate	uint256

quoteExactOutputSingle

quoteExactOutputSingle(struct IQuoterV2.QuoteExactOutputSingleParams) external

Returns the amount in required to receive the given exact output amount but for a swap of a single pool

Name	Type	Description
params	struct IQuoterV2.QuoteExactOutputSingleParams	The params for the quote, encoded as `QuoteExactOutputSingleParams` tokenIn The token being swapped in tokenOut The token being swapped out amountOut The desired output amount limitSqrtPrice The price limit of the pool that cannot be exceeded by the swap

Returns:

Name	Type	Description
amountIn	uint256
sqrtPriceX96After	uint160
initializedTicksCrossed	uint32
gasEstimate	uint256
