Pot, fee and price helpers: Pool prices

Root exports for a Pot and for pool prices. v12PredictPot(owner, salt?, kitchen?) derives a Pot’s address without reading a chain, potSalt and DEFAULT_POT_SALT give its salt, and kitchenExecutionFee() builds the read of the Kitchen’s fee per cook. sqrtPriceX96FromPrice and priceFromSqrtPriceX96 convert between a price and a pool’s sqrtPriceX96.

import { v12PredictPot, kitchenExecutionFee, sqrtPriceX96FromPrice } from "@eco-incorp/sauce";

`MAX_SQRT_PRICE_X96`

Variable · @eco-incorp/sauce

MAX_SQRT_PRICE_X96 = 1461446703485210103287273052203988822378723970342n

`MIN_SQRT_PRICE_X96`

Variable · @eco-incorp/sauce The bounds a V3 or V4 pool’s price is held within: TickMath.MIN_SQRT_RATIO and MAX_SQRT_RATIO.

MIN_SQRT_PRICE_X96 = 4295128739n

`priceFromSqrtPriceX96`

Function · @eco-incorp/sauce The price a pool at sqrtPriceX96 trades at, in quote tokens per one base token as a decimal string: the inverse of sqrtPriceX96FromPrice. Rounded to fractionDigits decimal places (default 18), half up, without trailing zeros.

export declare function priceFromSqrtPriceX96(sqrtPriceX96: bigint, tokens: PoolPriceTokens, options?: {
    readonly fractionDigits?: number;
}): string;

`sqrtPriceX96FromPrice`

Function · @eco-incorp/sauce The sqrtPriceX96 of a pool trading at price units of the quote token per one base token, in whole tokens: 2,700 USDC per WETH is sqrtPriceX96FromPrice("2700", { baseDecimals: 18, quoteDecimals: 6, baseIsToken0 }). Rounded down. Throws a RangeError for a price a pool cannot hold, outside [MIN_SQRT_PRICE_X96, MAX_SQRT_PRICE_X96). As a swap’s price limit it bounds both directions: selling token0 moves the pool’s price down, so the limit is a floor; selling token1 moves it up, so the limit is a ceiling.

export declare function sqrtPriceX96FromPrice(price: string | number | bigint, tokens: PoolPriceTokens): bigint;

`PoolPriceTokens`

Interface · @eco-incorp/sauce The two tokens a price is quoted in, and which of them is the pool’s token0.

export interface PoolPriceTokens {
    readonly baseDecimals: number;
    readonly quoteDecimals: number;
    readonly baseIsToken0: boolean;
}
