Inherits: SafeCallback

Abstract contract for performing a combination of actions on Uniswap v4.

Suggested uint256 action values are defined in Actions.sol, however any definition can be used

Functions​

constructor​

constructor(IPoolManager _poolManager) SafeCallback(_poolManager);

_executeActions​

internal function that triggers the execution of a set of actions on v4

inheriting contracts should call this function to trigger execution

function _executeActions(bytes calldata unlockData) internal;

_unlockCallback​

function that is called by the PoolManager through the SafeCallback.unlockCallback

function _unlockCallback(bytes calldata data) internal override returns (bytes memory);

Parameters

NameTypeDescription
databytesAbi encoding of (bytes actions, bytes[] params) where params[i] is the encoded parameters for actions[i]

_executeActionsWithoutUnlock​

function _executeActionsWithoutUnlock(bytes calldata actions, bytes[] calldata params) internal;

_handleAction​

function to handle the parsing and execution of an action and its parameters

function _handleAction(uint256 action, bytes calldata params) internal virtual;

msgSender​

function that returns address considered executor of the actions

The other context functions, _msgData and _msgValue, are not supported by this contract In many contracts this will be the address that calls the initial entry point that calls _executeActionsmsg.sender shouldn't be used, as this will be the v4 pool manager contract that calls unlockCallback If using ReentrancyLock.sol, this function can return _getLocker()

function msgSender() public view virtual returns (address);

_mapRecipient​

Calculates the address for a action

function _mapRecipient(address recipient) internal view returns (address);

_mapPayer​

Calculates the payer for an action

function _mapPayer(bool payerIsUser) internal view returns (address);

Errors​

InputLengthMismatch​

emitted when different numbers of parameters and actions are provided

error InputLengthMismatch();

UnsupportedAction​

emitted when an inheriting contract does not support an action

error UnsupportedAction(uint256 action);
