DMD Diamond's DAO Recovery of Coins Stranded on BitMart

When an exchange stops paying out, depositors usually wait on insolvency courts rather than code. DMD Diamond, a Layer 1 network that has operated since 2013, says it took a different route after BitMart stopped processing DMD withdrawals: a published vote, a voluntary software upgrade by validators and a written doctrine limiting when the step can be repeated. The details below come from the DMD Diamond Association, which is itself a party to the case, so readers should check them against the public block explorer.

The Stranded Balance

The Association says BitMart's wallets held roughly 240,000 DMD at their peak. By the time withdrawals stopped, it says the on-chain balance had fallen to 123,214.74746996 DMD, or 2.81312209% of total supply, while verified depositor claims have since passed 180,000 DMD. The Association reads that gap as a sign coins left the wallets before the halt became public, which makes the shortfall a matter for BitMart and its creditors rather than something a fork can fix.

It also argues that an unexplained balance of that size, held by an entity that has stopped communicating, is a risk to the market and to a governance system in which coins carry votes. BitMart's wider troubles are documented elsewhere: it announced a wind-down in July, halted trading on August 26, 2026 and has said it will terminate operations on January 31, 2027, while users have reported frozen withdrawals.

Two Gates Instead of a Key

The recovery ran through two independent steps. A first governance proposal set the mandate for targeted recovery and proportional redistribution, and the Association reports 77.32% participation with 96.68% in favor. A second proposal set the fork's parameters, including its timestamp and the destination of the funds.

Neither vote moved a coin by itself. The change lived in the node software, and each validator had to decide independently whether to run it. The Association says it holds no key that would let it proceed alone. At the set timestamp, the software set the custodial balance to zero and credited it to a recovery contract governed by the DAO, with no block reorganized and no historical transaction altered.

How It Compares

Case	Who decided	Outcome
Ethereum, 2016	Off-chain signaling by miners and holders	Executed; network split into ETH and ETC
Steem, 2020	Community developers, no binding vote	Two competing chains
Juno, 2022	On-chain vote of coin holders	One holder's balance cut; widely contested
Bitcoin, 2026	Proposed by an individual	Never adopted; rejected by developers
DMD Diamond, 2026	On-chain vote plus voluntary validator adoption	Executed; no competing chain reported

The Juno vote in 2022 passed narrowly, and critics argued that a rule that can be voted away is not a rule. The Bitcoin entry refers to the February 2026 proposal by former Mt. Gox chief executive Mark Karpelès for a consensus exception covering about 80,000 stolen BTC. The Association's counterargument is that, here, immutability would have protected a defaulting custodian rather than a user.

Four Conditions

The doctrine the network adopted limits protocol-level reassignment to cases where four things hold at once. The address must belong to a documented custodial intermediary that has ceased operating and defaulted on releasing funds. Documentary evidence must show the coins belong to third-party depositors. The concentration must be large enough to threaten market integrity or network security. Both the vote and the voluntary validator adoption must clear in sequence.

"The obvious way to do this would have been an administrative key held by the Association, and that is the capability we did not want to own."

Claims and Open Questions

Depositors have 90 days from the opening of the verification window to file, with authenticated transaction records, exchange account export logs and matching identity documents. Payouts will be proportional, so repayment at parity is impossible, and the Association says it has said so up front. A final distribution ledger returns to the DAO as a third proposal, and no coin leaves the contract until that passes. BitMart has the same 90 days to present its own settlement plan.

Several questions remain open. The shortfall cannot be closed by governance, collecting records from an unresponsive exchange is hard, and the doctrine has been used once, in a case where sympathies were clear. The Association itself says the next claim will be the real test.
