Prime Trust Wins $9M Default Judgment Against Poloniex

The bankruptcy estate of Prime Trust, the now-collapsed US crypto custodian, has obtained a $9 million default judgment against Polo Digital Assets Ltd, the entity that operates the Poloniex cryptocurrency exchange. The ruling, which lands in the middle of a broader web of adversary proceedings involving Justin Sun-affiliated companies, carries real accounting and legal exposure implications for any firm that maintained commercial relationships with distressed crypto counterparties in the period before a bankruptcy filing.

Background: How Prime Trust Collapsed

Prime Trust was a Nevada-chartered trust company that provided custody, payments, and compliance infrastructure to crypto businesses across the United States. Its failure was not a single event but the result of compounding operational failures, most critically an inability to adequately safeguard the cryptocurrency assets it held on behalf of customers.

The custody failures that triggered insolvency

When those custody shortfalls became apparent, Prime Trust reportedly resorted to using customer deposits in an attempt to cover the gap. That decision accelerated the path to insolvency. By the time the company filed for bankruptcy protection, the estate faced a significant deficit between the assets it held and the liabilities it owed to customers and creditors. Courts overseeing the estate have since been tasked with recovering as much value as possible for those creditors, including through adversary proceedings against parties that received transfers before the filing date.

The Sun connection and the pre-bankruptcy wind-down

Shortly before its bankruptcy filing, Prime Trust took the decision to terminate its relationships with entities connected to Justin Sun, including Poloniex. That decision was made in the context of a Securities and Exchange Commission lawsuit against Sun that was active at the time, though that particular action has since been dropped. The timing matters for the adversary proceeding: transfers made to Sun-linked entities during the wind-down period are exactly the kind of transactions that bankruptcy trustees examine for preferential transfer claims.

The Adversary Proceeding and the $9 Million Judgment

Prime Trust's estate filed an adversary proceeding seeking to claw back funds transferred to Justin Sun and to Poloniex before the bankruptcy. Adversary proceedings of this kind are a standard tool in US bankruptcy law, allowing an estate to recover assets transferred to creditors or counterparties within defined look-back windows under the US Bankruptcy Code's preference and fraudulent transfer provisions.

What the default judgment means in practice

The $9 million default judgment has been entered specifically against Polo Digital Assets Ltd, the Poloniex operating entity. A default judgment is entered when the defendant fails to respond to or contest the action within the required timeframe. It is not an admission of wrongdoing by the defendant, but it creates an enforceable monetary obligation. Collecting on a default judgment against an entity that may hold assets in multiple jurisdictions can itself be a complex process, and the practical recovery timeline remains open.

Crucially, litigation against Justin Sun personally is not yet concluded. The estate is still in discovery against Sun himself, meaning the total financial exposure from this adversary proceeding could increase once that phase concludes and any further claims are adjudicated.

Poloniex is not the only Sun-linked entity in the crosshairs

The Prime Trust case is not operating in isolation. The FTX estate has separately filed adversary proceedings against Sun-owned HTX (formerly Huobi) and Poloniex, as well as against Sun personally. The parallel litigation from two major crypto bankruptcy estates against overlapping defendants adds weight to the argument that any firm with exposure to Sun-affiliated entities should be conducting a thorough review of its transaction history and documented due diligence records.

Accounting and Reporting Implications for Firms

For accounting firms, CFOs, and finance teams advising or supporting businesses that had commercial relationships with Prime Trust or Poloniex, this judgment surfaces a set of practical questions that need answers on the balance sheet and in the audit file.

Clawback risk and contingent liabilities

Preferential transfer claims in bankruptcy are not limited to the direct parties in a case. Any firm that received a payment from an entity that subsequently went insolvent within the relevant look-back period could, in principle, face its own clawback demand. Under Chapter 7 and Chapter 11 of the US Bankruptcy Code, transfers made to non-insider creditors within 90 days of the filing, or to insiders within one year, may be recoverable by the estate if they meet the statutory preference criteria.

This means that finance teams should be reviewing whether any crypto-related counterparty in their transaction history has since entered bankruptcy, and whether payments received from that counterparty fall within a statutory preference window. If potential exposure exists, it should be disclosed as a contingent liability in the financial statements and documented in the audit file. Reliable crypto bookkeeping software that timestamps and categorises all counterparty transactions is essential for constructing that historical record quickly when a demand arrives.

Counterparty due diligence as an ongoing obligation

The Prime Trust situation also reinforces that counterparty due diligence is not a one-time onboarding exercise. Prime Trust made a conscious decision to wind down its Sun-linked relationships when the SEC lawsuit became public, suggesting that reputational and regulatory signals were available to market participants at the time. Firms that maintained or expanded relationships with the same entities after those signals emerged may face harder questions in any subsequent litigation or regulatory inquiry.

A documented, repeatable counterparty monitoring process, one that captures regulatory filings, enforcement actions, and changes in ownership, is now a basic expectation in digital asset accounting and risk management. Digital asset accounting software that integrates counterparty metadata with transaction records helps firms demonstrate they acted on available information rather than ignoring it.

Audit considerations for crypto custodian relationships

The Prime Trust collapse is also a reminder that using a crypto custodian does not transfer legal or financial risk entirely to that custodian. Auditors reviewing client accounts that held assets through Prime Trust will need to assess whether those assets were recoverable, whether any recovery has been booked at the correct value, and whether any residual claims against the estate are adequately reflected. Given that bankruptcy distributions typically occur over years, the accounting treatment of claims against a crypto estate, including the discount for uncertainty and the timing of recognition, requires specific professional judgment.

For a broader view of how US enforcement actions are reshaping compliance obligations for crypto firms, see how US crypto enforcement is reshaping firm obligations in 2026. The pattern of courts upholding financial penalties against crypto entities is also visible in the Gemini CFTC settlement that a federal judge refused to vacate, another case where an attempt to relitigate a prior outcome failed.

What the FTX Parallel Proceedings Signal

The fact that the FTX estate is pursuing overlapping defendants, specifically Poloniex and HTX as well as Justin Sun personally, is significant beyond the headline dollar amounts. It indicates that multiple bankruptcy trustees, working independently, have assessed the same counterparty relationships and concluded that adversary proceedings are justified. When two separate estates reach the same conclusion about the same defendants, it strengthens the factual and legal picture in each case, even if the proceedings remain formally separate.

For accounting and legal advisers, the convergence of these two major crypto bankruptcy cases on a single network of related entities is a signal worth tracking. Any client or counterparty with historical ties to the HTX or Poloniex ecosystems, or to Justin Sun-affiliated ventures more broadly, warrants a documented risk assessment in the current environment.

Next Steps for Finance and Compliance Teams

Immediate actions to consider

Firms that had direct relationships with Prime Trust or Poloniex should pull a complete transaction history for the period running up to and including Prime Trust's bankruptcy filing date. The relevant look-back windows under US bankruptcy law are well-established, and determining whether any transfers fall within them is a straightforward first step. If potential exposure is identified, early engagement with restructuring counsel is advisable before a formal demand is received.

Firms with indirect exposure, such as those that used Prime Trust as a sub-custodian or that processed payments through Poloniex, should document that relationship clearly and assess whether any assets remain unrecovered from the estate. Proof of claim deadlines in bankruptcy cases are strict, and missing them can permanently bar recovery.

Longer-term process improvements

This case, alongside the continuing FTX estate proceedings, makes the case for treating crypto counterparty risk with the same rigour applied to traditional financial institution relationships. That means periodic creditworthiness reviews, documented escalation procedures when regulatory signals emerge, and a transaction record that can be reconstructed quickly and completely using robust crypto accounting software. The ability to produce a timestamped, categorised ledger of all counterparty payments is not just good practice; it is increasingly a prerequisite for defending against preference claims and demonstrating compliance to auditors and regulators.
