Orderbook ledger and disclosure

On 5 October 2026 we published the ledger of every orderbook balance at the halt on 14 December 2024, together with a disclosure of an attempted attack on the chain in May 2026. The release, its files and their checksums are on GitHub.

What happened

The orderbook stopped on 14 December 2024. We recovered its ledger, the balance of every account as it stood when it stopped, from a validator's database, and verified it against the hash the chain recorded at the time: 911 accounts and 2,504 rows, matching snapshot 694,063. The 28 deposits made into the orderbook after it stopped, from 16 December 2024 to 20 January 2025, are published with it.

In May 2026 an attempt was made to take the pooled user funds the orderbook still held off the chain, using a defect in the retired orderbook settlement module. The attempt failed: the funds could not leave the chain. The Council has since frozen the assets involved. The chain's consensus and the PDEX token were never at risk, and no user's own wallet was ever reachable.

Am I affected?

• You only held tokens in your own wallet: none of this concerns you.
• You had a balance on the orderbook when it stopped, or deposited after it: your line is in the published files, shown by the first and last four characters of your address. The return comes through governance without any action on your part.

What happens next

Runtime upgrade 392 removes the module that held the defect and goes to a public vote. The network intends to return every balance in the ledger, and every later deposit, through a governance proposal in the upgrade after 392. That proposal will be published for review before any vote, and each step will be announced.

There is nothing to claim

No form, no claim site, no wallet to connect, no transaction to sign. The team will never message you first or ask for your keys. Anyone who does is a scammer. The only official record is the GitHub release linked on this page.
