Execute An Elastic Swap

Trade Directly Against An Elastic Pool

Obtaining pool addresses

It is necessary to specify which pools are to be used for the token swap. Read more about fetching pool addresses before proceeding.

Elastic SDK

KyberSwap has created an Elastic SDK to make interacting with our Elastic smart contracts easier. You can refer to our Elastic SDK Developer Guides for step-by-step walkthroughs on how to achieve various Elastic operations in a TypeScript environment.

Executing a swap

After getting a pool address from getPool(), you can call swap() function to execute a swap.

swap()​

Swap token0 -> token1, or vice versa. Note that swaps will either fully use up the specified swap quantity, or swap up to the specified price limit, depending on whichever condition is satisfied first.

Input​

Field	Type	Explanation
recipient	address	address to receive the swap output
swapQty	int256	swap quantity, which implicitly configures the swap as exact input (>0), or exact output (<0)
isToken0	bool	whether the swapQty is specified in token0 (true) or token1 (false)
limitSqrtP	uint160	sqrt price limit to reach
data	bytes	Data, if any, to be passed into the callback function

Note​

To specify an unlimited price limit for a swap, use the following values.

isToken0	swapQty	Value
true	> 0	MIN_SQRT_RATIO + 1
true	< 0	MAX_SQRT_RATIO - 1
false	> 0	MAX_SQRT_RATIO - 1
false	< 0	MIN_SQRT_RATIO + 1

Output​

Field	Type	Explanation
qty0	int256	exact token0 qty sent to recipient if < 0. Minimally received quantity if > 0
qty1	int256	exact token1 qty sent to recipient if < 0. Minimally received quantity if > 0
