ISwapRouter
Functions for swapping tokens via Pegasys V3
Parameter Structs
Note that fee
is in hundredths of basis points (e.g. the fee
for a pool at the 0.3% tier is 3000; the fee
for a pool at the 0.01% tier is 100).

Functions
exactInputSingle
function exactInputSingle(
struct ISwapRouter.ExactInputSingleParams params
) external returns (uint256 amountOut)
Swaps amountIn
of one token for as much as possible of another token
Parameters:
Name | Type | Description |
---|---|---|
params | struct ISwapRouter.ExactInputSingleParams | The parameters necessary for the swap, encoded as ExactInputSingleParams in calldata |
Return Values:
Name | Type | Description |
---|---|---|
amountOut | struct ISwapRouter.ExactInputSingleParams | The amount of the received token |
exactInput
function exactInput(
struct ISwapRouter.ExactInputParams params
) external returns (uint256 amountOut)
Swaps amountIn
of one token for as much as possible of another along the specified path
Parameters:
Name | Type | Description |
---|---|---|
params | struct ISwapRouter.ExactInputParams | The parameters necessary for the multi-hop swap, encoded as ExactInputParams in calldata |
Return Values:
Name | Type | Description |
---|---|---|
amountOut | struct ISwapRouter.ExactInputParams | The amount of the received token |
exactOutputSingle
function exactOutputSingle(
struct ISwapRouter.ExactOutputSingleParams params
