IUniswapV3Pool

Title: IUniswapV3Pool

Author: Vendored minimal subset of Uniswap V3 (https://github.com/Uniswap/v3-core/blob/main/contracts/interfaces/IUniswapV3Pool.sol

and .../interfaces/pool/IUniswapV3PoolDerivedState.sol). Upstream license: GPL-2.0-or-later.

Minimal vendored subset of a Uniswap V3 pool, covering only what the Lattice UniswapV3Adapter needs: the time-weighted observe oracle (the manipulation-resistant valuation source), the immutable token/fee/tick-spacing readers, and slot0 (declared for completeness / tests — the adapter MUST NEVER value its position from slot0 because the spot tick is single-block manipulable).

Vendored subset — do not add a uniswap-v3-core dependency. Valuation reads are view.

Functions

observe

Returns cumulative tick and liquidity-in-range values as of each secondsAgo.

The TWAP arithmetic-mean tick over a window w is (tickCumulatives[0] - tickCumulatives[1]) / int56(uint56(w)) for secondsAgos = [w, 0]. This is the canonical Uniswap V3 oracle and is the ONLY price source the adapter uses for NAV — it is resistant to single-block manipulation because it averages the tick over the whole window.

function observe(uint32[] calldata secondsAgos)
        external
        view
        returns (int56[] memory tickCumulatives, uint160[] memory secondsPerLiquidityCumulativeX128s);

Parameters

Name	Type	Description
secondsAgos	`uint32[]`	From how long ago each cumulative value should be returned (seconds).

Returns

Name	Type	Description
tickCumulatives	`int56[]`	Cumulative tick values as of each `secondsAgos` from the current block.
secondsPerLiquidityCumulativeX128s	`uint160[]`	Cumulative seconds-per-liquidity-in-range values.

slot0

The current pool state (slot0). Manipulation hazard: sqrtPriceX96/tick here are the instantaneous spot price, settable within a single block by a flash swap. The adapter declares this only so callers/tests can observe spot; it is NEVER used for NAV.

function slot0()
        external
        view
        returns (
            uint160 sqrtPriceX96,
            int24 tick,
            uint16 observationIndex,
            uint16 observationCardinality,
            uint16 observationCardinalityNext,
            uint8 feeProtocol,
            bool unlocked
        );

Returns

Name	Type	Description
sqrtPriceX96	`uint160`	The current price as a sqrt(token1/token0) Q64.96 value.
tick	`int24`	The current tick.
observationIndex	`uint16`	The index of the last written observation.
observationCardinality	`uint16`	The current maximum number of observations stored.
observationCardinalityNext	`uint16`	The next maximum number of observations.
feeProtocol	`uint8`	The protocol fee for both tokens of the pool.
unlocked	`bool`	Whether the pool is currently locked to reentrancy.

tickSpacing

The pool tick spacing (governs which ticks may be initialized; full-range positions use the min/max usable ticks aligned to this spacing).

function tickSpacing() external view returns (int24);

Returns

Name	Type	Description
<none>	`int24`

token0

The first of the two tokens of the pool, sorted by address.

function token0() external view returns (address);

Returns

Name	Type	Description
<none>	`address`

token1

The second of the two tokens of the pool, sorted by address.

function token1() external view returns (address);

Returns

Name	Type	Description
<none>	`address`

fee

The pool's fee in hundredths of a bip (i.e. 1e-6).

function fee() external view returns (uint24);

Returns

Name	Type	Description
<none>	`uint24`
