State-Changing Functions

quoteExactInput

function quoteExactInput(bytes memory path, uint256 amountIn) external returns (uint256 amountOut, uint16[] memory fees);

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

Params

• path The path of the swap, i.e. each token pair
• amountIn The amount of the first token to swap

Return

• amountOut The amount of the last token that would be received

quoteExactInputSingle

function quoteExactInputSingle(address tokenIn, address tokenOut, uint256 amountIn, uint160 limitSqrtPrice) external returns (uint256 amountOut, uint16 fee);

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

Params

• 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

Return

• amountOut The amount of tokenOut that would be received

quoteExactOutput

function quoteExactOutput(bytes memory path, uint256 amountOut) external returns (uint256 amountIn, uint16[] memory fees);

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

Params

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

Return

• amountIn The amount of first token required to be paid

quoteExactOutputSingle

function quoteExactOutputSingle(address tokenIn, address tokenOut, uint256 amountOut, uint160 limitSqrtPrice) external returns (uint256 amountIn, uint16 fee);

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

Params

• 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

Return

• amountIn The amount required as the input for the swap in order to receive amountOut
