#1502 · Reimbursement for corrupted staking ledgers

SUMMARY

The Polkadot runtime upgrade to v1.1.2 introduced an unintentional breaking change that prevented three staking accounts from receiving staking rewards across multiple eras. This proposal seeks to reimburse these accounts for the rewards they should have earned for backing validators and securing the network.

The process was detailed by core developer gpestana in multiple articles compiled in the following Polkadot Forum post:

Recover corrupted Staking ledgers in Polkadot and Kusama

The referendum could not be proposed until the runtime upgrade to v1.4.0, which corrected the balance state of one of the affected accounts (PR 538).

TIMELINE

  • 2024-02-19 Breaking change introduced in runtime upgrade v1.1.2
  • 2024-03-15 Hotfix on runtime upgrade to v1.1.3.
  • 2024-10-15 Runtime upgrade to v1.3.3 set the correct ledger/stash status.
  • 2025-02-26 The balance issue for one of the accounts was corrected on runtime v.1.4.0.

PROPOSAL DETAILS

Each account faced a unique situation, and the analysis took into account the bonded funds at the time rewards ceased, the number of eras the payee account went without receiving rewards, and the average APY during that period.

Below is the information for each affected account:
