PredicateHelper
A helper contract for executing boolean functions on arbitrary target call results
Functions
or
function or(
address[] targets,
bytes[] data
) external returns (bool)
Calls every target with corresponding data
Parameters:
Name | Type | Description |
---|---|---|
targets | address[] | |
data | bytes[] |
Return Values:
Name | Type | Description |
---|---|---|
Result | bool | True if call to any target returned True. Otherwise, false |
and
function and(
address[] targets,
bytes[] data
) external returns (bool)
Calls every target with corresponding data
Parameters:
Name | Type | Description |
---|---|---|
targets | address[] | |
data | bytes[] |
Return Values:
Name | Type | Description |
---|---|---|
Result | bool | True if calls to all targets returned True. Otherwise, false |
eq
function eq(
uint256 value,
address target,
bytes data
) external returns (bool)
Calls target with specified data and tests if it's equal to the value
Parameters:
Name | Type | Description |
---|---|---|
value | uint256 | Value to test |
target | address | |
data | bytes |
Return Values:
Name | Type | Description |

Result | bool | True if call to target returns the same value as value . Otherwise, false |
lt
function lt(
uint256 value,
address target,
bytes data
) external returns (bool)
Calls target with specified data and tests if it's lower than value
Parameters:
Name | Type | Description |
---|---|---|
value | uint256 | Value to test |
target | address | |
data | bytes |
Return Values:
Name | Type | Description |
---|---|---|
Result | bool | True if call to target returns value which is lower than value . Otherwise, false |
gt
function gt(
uint256 value,
address target,
bytes data
) external returns (bool)
Calls target with specified data and tests if it's bigger than value
Parameters:

timestampBelow
function timestampBelow(
uint256 time
) external returns (bool)
Checks passed time against block timestamp
Parameters:
