IQuoter
Quoter Interface
Supports quoting the calculated amounts from exact input or exact output swaps
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. Credit to Uniswap Labs under GPL-2.0-or-later license: https://github.com/Uniswap/v3-periphery
Functions
quoteExactInput
function quoteExactInput(bytes path, uint256 amountIn) external returns (uint256 amountOut, uint16[] fees) external
Returns the amount out received for a given exact input swap without executing the swap
path
bytes
The path of the swap, i.e. each token pair
amountIn
uint256
The amount of the first token to swap
Returns:
amountOut
uint256
The amount of the last token that would be received
fees
uint16[]
quoteExactInputSingle
function quoteExactInputSingle(address tokenIn, address tokenOut, uint256 amountIn, uint160 limitSqrtPrice) external returns (uint256 amountOut, uint16 fee) external
Returns the amount out received for a given exact input but for a swap of a single pool
tokenIn
address
The token being swapped in
tokenOut
address
The token being swapped out
amountIn
uint256
The desired input amount
limitSqrtPrice
uint160
The price limit of the pool that cannot be exceeded by the swap
Returns:
amountOut
uint256
The amount of `tokenOut` that would be received
fee
uint16
quoteExactOutput
function quoteExactOutput(bytes path, uint256 amountOut) external returns (uint256 amountIn, uint16[] fees) external
Returns the amount in required for a given exact output swap without executing the swap
path
bytes
The path of the swap, i.e. each token pair. Path must be provided in reverse order
amountOut
uint256

quoteExactOutputSingle
function quoteExactOutputSingle(address tokenIn, address tokenOut, uint256 amountOut, uint160 limitSqrtPrice) external returns (uint256 amountIn, uint16 fee) external
Returns the amount in required to receive the given exact output amount but for a swap of a single pool
tokenIn
address
The token being swapped in
tokenOut
address
The token being swapped out
amountOut
uint256
The desired output amount
limitSqrtPrice
uint160
The price limit of the pool that cannot be exceeded by the swap
Returns:
amountIn
uint256
The amount required as the input for the swap in order to receive `amountOut`
fee
uint16
