Usage​

/// Angstrom Adapter swap()
    function swap(
        PoolKey calldata key,
        bool zeroForOne,
        uint128 amountIn,
        uint128 minAmountOut,

        address recipient,
        uint256 deadline
    ) external returns (uint256 amountOut);

Using Multiple Bundle/Unlock Attestations​

The Angstrom Adapter has the capability to receive multiple attestations for multiple blocks. The _selectAttestation() is used in the contract to select the one corresponding to the valid block. The usage stems from the multiple unlock attestations that can be received from the Attestations API. This will help guarantee multi-block validity.
