Components

SubProxy

The SubProxy is the SubDAO level counter-party of the MakerDAO level MCD_PAUSE_PROXY.

The reason a Proxy is required is to isolate the context of execution for spells from the main governance contract to avoid potential exploits messing with the original contract storage.

This module is heavily inspired by the original DSPauseProxy contract, with a few modifications:

1. Instead of a single owner, it uses the now classic wards/rely/deny pattern from MCD.
2. The exec function is payable.

Interface

rely(address usr)

Grants usr access to execute calls through this contract.

deny(address usr)

Revokes usr access to execute calls through this contract.

exec(address target, bytes memory args) payable returns (bytes memory out)

Executes a calldata-encoded call args on target through delegatecall.
The caller must have been relyed before.
