Call Header
For example, FCT Runner can allow a specific address (child account) to run only FCTs that has 0x0001 permission, while limiting execution of FCTs with 0x0001 permissions in terms of protocols, amounts and rate.
flow_control
FCT supports if/then functionality via the flow_control field combined with the "jump on" fields.
flow_control is defined using human readable string, so the user can easily see the flow condition.
| EIP712 String | Value | Meaning |
|---|---|---|
"continue on success, revert on fail" | 0 | If call reverts, revert the whole FCT, otherwise, continue to the next call according to the jump_on_success field |
"continue on success, stop on fail" | 1 | If call reverts, stop FCT execution (previous calls are not reverted), otherwise, continue to the next call according to the jump_on_success field |
"continue on success, continue on fail" | 2 | Whether call reverts or not, continue to the next call according to the jump_on_success and jump_on_fail fields respectively |
"revert on success, continue on fail" | 3 | If call reverts, continue to the next call according to the jump_on_fail field, otherwise, revert the whole FCT |
"revert on success, stop on fail" | 4 | If call reverts, stop FCT execution (previous calls are not reverted), otherwise, revert the whole FCT |
"stop on success, continue on fail" | 5 | If call reverts, continue to the next call according to the jump_on_fail field, otherwise, stop FCT execution (previous calls are not reverted) |
"stop on success, revert on fail" | 6 | If call reverts, revert the whole FCT, otherwise, stop FCT execution (previous calls are not reverted) |
"stop on success, stop on fail" | 7 | Whether call reverts or not, stop FCT execution (previous calls are not reverted) |
if/then blocks can be achieved by using one of the "cont" flow controls and setting the "jump_on" values
jump_on_success
Part of the flow control. Specify the amount of calls to jump over when current call succeed. When setting to 0 and the current call succeed, the adjacent call will be executed.
This value is ignored when "stop on success" or "revert on success" is being used
jump_on_fail
Part of the flow control. Specify the amount of calls to jump over when current call fails. When setting to 0 and the current call fails, the adjacent call will be executed.
This value is ignored when "stop on fail" or "revert on fail" is being used
method_interface
The name of the function to be called followed by type-names, in parentheses, without any spaces. This is used in order to calculate the function signature and selector. See more info here
ERC20 transfer method interface looks like this: "transfer(address,uint256)"
