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
