A contract bug that could cause a delegator that claims its stake on L2 to be delegated to the null address and unable to move its stake was recently brought to the core team’s attention. A fix for the bug has been deployed and there should be no cases of stake being unmovable or inaccessible after a delegator claims its stake on L2.
The main problems were that:
- It was possible for a delegator that claimed its stake on L2 to become delegated to the null address such that:
- The delegator would not be able to move its stake away from the null address
- There was the possibility of accounting discrepancies upon further staking actions that could make some of a delegator’s stake inaccessible
The deployment of this bug fix is a part of the governance failsafes procedure described in [1]. The bug created the opportunity for a delegator that claims its stake on L2 to potentially lose access to some of its stake in the course of normal staking actions. With this in mind, the core team moved forward with a fix swiftly to resolve this issue for the community as soon as possible.
