Pot, fee and price helpers: Pot address and Kitchen fee

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";

Generated from the type declarations of @eco-incorp/sauce.

`potSalt`

Function · @eco-incorp/sauce The salt of the Pot an owner names label: keccak256(utf8(label)). An owner has one Pot per salt. The zero salt (DEFAULT_POT_SALT) is the convention for the one Pot an owner has by default, and a label names any other: v12PredictPot(owner, potSalt("treasury")). Hashing gives any label a full 32-byte salt, the same everywhere: the sauce command’s --salt treasury is this. An exact salt needs no helper; pass the 32 bytes to v12PredictPot as they are.

export declare function potSalt(label: string): Hex;

`DEFAULT_POT_SALT`

Variable · @eco-incorp/sauce The salt of an owner’s default Pot: zero. A Pot is fixed by its (owner, salt) pair, so this is not a namespace: whoever calls Kitchen.deployPot(owner, 0) creates this same Pot, owned by owner, and nobody can create a different one there.

DEFAULT_POT_SALT: Hex

`v12PredictPot`

Function · @eco-incorp/sauce CREATE2(kitchen, keccak256(abi.encode(owner, salt)), initCodeHash) - the formula V12Deployments.json records, applied. kitchen defaults to the pinned release’s Kitchen proxy, the Pots’ deployer; the init-code hash is always the pinned release’s, never a constant here. Chain-independent, like every CREATE2 address: the same owner and salt give the same Pot on every chain the Kitchen is deployed at that address on. A Kitchen upgrade that moves the init-code hash moves every Pot minted after it - the reason this reads the hash from the release.

export declare function v12PredictPot(owner: Hex, salt?: Hex, kitchen?: Hex): Hex;

`kitchenExecutionFee`

Function · @eco-incorp/sauce Kitchen.executionFee(), as a request plus its decoder.

const request = kitchenExecutionFee();
const fee = request.decode(await client.call(request).then((r) => r.data!));

Read it shortly before building a cook: an increase between the read and the cook makes the cook revert.

export declare function kitchenExecutionFee(kitchen?: Hex): ExecutionFeeCall;

`ExecutionFeeCall`

Interface · @eco-incorp/sauce

export interface ExecutionFeeCall {
    readonly to: Hex;
    readonly data: Hex;
    decode(result: Hex): bigint;
}
