Functions for swapping tokens via DragonswapV2
Parameter Structsโ
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).

of one token for as much as possible of another token
Parameters:โ
params
struct ISwapRouter.ExactInputSingleParams
The parameters necessary for the swap, encoded as ExactInputSingleParams
in calldata
Return Values:โ
amountOut
struct ISwapRouter.ExactInputSingleParams
The amount of the received token
exactInputโ
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:โ
params
struct ISwapRouter.ExactInputParams
The parameters necessary for the multi-hop swap, encoded as ExactInputParams
in calldata
Return Values:โ
amountOut
struct ISwapRouter.ExactInputParams
The amount of the received token
exactOutputSingleโ
function exactOutputSingle(
struct ISwapRouter.ExactOutputSingleParams params
) external returns (uint256 amountIn)
