Methods
getInputAmount
▸ getInputAmount(outputAmount, sqrtPriceLimitX96?): Promise<[CurrencyAmount<Token>, Pool]>
Given a desired output amount of a token, return the computed input amount and a pool with state updated after the trade
Parameters
| Name | Type | Description |
|---|---|---|
outputAmount | CurrencyAmount<Token> | the output amount for which to quote the input amount |
sqrtPriceLimitX96? | default | The Q64.96 sqrt price limit. If zero for one, the price cannot be less than this value after the swap. If one for zero, the price cannot be greater than this value after the swap |
Returns
Promise<[CurrencyAmount<Token>, Pool]>
The input amount and the pool with updated state
Defined in
getOutputAmount
▸ getOutputAmount(inputAmount, sqrtPriceLimitX96?): Promise<[CurrencyAmount<Token>, Pool]>
Given an input amount of a token, return the computed output amount, and a pool with state updated after the trade
Parameters
| Name | Type | Description |
|---|---|---|
inputAmount | CurrencyAmount<Token> | The input amount for which to quote the output amount |
sqrtPriceLimitX96? | default | The Q64.96 sqrt price limit |
Returns
Promise<[CurrencyAmount<Token>, Pool]>
The output amount and the pool with updated state
Defined in
involvesToken
▸ involvesToken(token): boolean
Returns true if the token is either token0 or token1
Parameters
| Name | Type | Description |
|---|---|---|
token | Token | The token to check |
Returns
boolean
True if token is either token0 or token
Defined in
priceOf
▸ priceOf(token): Price<Token, Token>
Return the price of the given token in terms of the other token in the pool.
Parameters
| Name | Type | Description |
|---|---|---|
token | Token | The token to return price of |
Returns
Price<Token, Token>
The price of the given token, in terms of the other.
Defined in
swap
▸ Private swap(zeroForOne, amountSpecified, sqrtPriceLimitX96?): Promise<{ amountCalculated: default ; liquidity: default ; sqrtRatioX96: default ; tickCurrent: number \}>
Executes a swap
Parameters
| Name | Type | Description |
|---|---|---|
zeroForOne | boolean | Whether the amount in is token0 or token1 |
amountSpecified | default | The amount of the swap, which implicitly configures the swap as exact input (positive), or exact output (negative) |
sqrtPriceLimitX96? | default | The Q64.96 sqrt price limit. If zero for one, the price cannot be less than this value after the swap. If one for zero, the price cannot be greater than this value after the swap |
Returns
Promise<{ amountCalculated: default ; liquidity: default ; sqrtRatioX96: default ; tickCurrent: number }>
amountCalculated
sqrtRatioX96
liquidity
