Crypto Disputes in Singapore Courts: Property, Trusts and Stolen Coins

Singapore has spent a decade making itself one of the world's most hospitable homes for digital assets — licensed exchanges, a regulator that engages rather than bans, a steady migration of crypto businesses to the city-state. Less noticed, but at least as important, its courts have quietly assembled one of the clearest bodies of cryptocurrency law anywhere in the common law world. If your coins are stolen, your NFT is seized by a lender you know only by a username, or your exchange reverses a trade you thought was final, Singapore is one of the few places on earth where you can say with reasonable confidence what a judge will do about it.

That confidence rests on a single, deceptively simple proposition: cryptocurrency is property. Not money, not a gambling chip, not a string of characters with no legal home — property, capable of being owned, traced, frozen and held on trust. Nearly everything else in this guide flows from that proposition, so that is where we begin.

What follows covers the leading Singapore decisions, the interim remedies available when coins vanish, how to sue a thief you cannot name, how to make exchanges reveal who their customers are, what happens when your dispute is with the platform itself, and — because honesty matters more than optimism in this field — what recovery realistically looks like.

Cryptocurrency is property: the ByBit case

The foundational modern authority is ByBit Fintech Ltd v Ho Kai Xin [2023] SGHC 199. An employee of a payroll services provider engaged by the ByBit exchange abused her access to payroll spreadsheets and directed more than four million USDT — Tether's US-dollar stablecoin — to cryptocurrency addresses she controlled. When ByBit sued, the High Court had to confront the prior question head on: is a crypto asset something the law recognises as property at all?

The court held that it is. A holder of USDT has a right the law will protect, classified as a thing in action — the same broad family as debts and other rights enforceable by legal action — and misappropriated tokens can be impressed with a constructive trust in favour of their true owner. The employee held the stolen USDT on trust for ByBit and was ordered to give it back.

Why does the label matter so much? Because property status unlocks the strongest remedies in the civil-litigation toolkit:

Proprietary claims. You are not merely a creditor owed a sum of money; you can claim the coins themselves, and their traceable substitutes, in whoever's hands they end up (short of a good-faith purchaser).
Trust remedies. A constructive trust turns the thief into a trustee, with all the duties and disgorgement obligations that follow.
Priority on insolvency. If the wrongdoer goes bankrupt, assets held on trust for you generally sit outside the estate, ahead of the queue of unsecured creditors.
Interim protection. Property can be the subject of a proprietary injunction — the remedy that does the real work in crypto fraud cases, as the next section explains.

Freezing stolen coins: proprietary and worldwide injunctions

The remedy a crypto theft victim usually needs first is not damages but a standstill: an order stopping the coins from moving again while the claim is fought. Singapore granted exactly that in CLM v CLN [2022] SGHC 46, one of the first reported Singapore decisions to deploy the injunction armoury against crypto fraud. A claimant whose Bitcoin and Ether had been misappropriated traced a portion of them into identifiable wallets and exchange accounts. The High Court granted a proprietary injunction over the stolen assets and their traceable proceeds, together with a worldwide freezing order against the unidentified defendants — and made supporting orders against cryptocurrency exchanges connected to Singapore.

The two orders do different jobs. A proprietary injunction attaches to specific assets you claim are yours — these coins, in these wallets, and whatever they are swapped into. A freezing order restrains a defendant from dealing with their assets generally, up to the value of your claim, whether or not those assets are yours. In a crypto case you typically want both: the proprietary order to hold the traced coins, the freezing order to catch value that has already leaked beyond the tracing exercise. The general law of freezing orders — the real-risk-of-dissipation test, the cross-undertaking in damages you must give, the duty of full and frank disclosure on a without-notice application — is covered in our guide to freezing orders; all of it applies with full force here, and the price of getting it wrong is the same.

What makes crypto different is tempo. Coins can cross three exchanges and a mixing service in an afternoon. Applications are made urgently and without notice, often within days of discovery, supported by an affidavit exhibiting the blockchain analysis. Courts have shown themselves willing to move at that speed — but only for claimants who arrive with their evidence organised.

Suing a wallet address: claims against persons unknown

The defining awkwardness of crypto fraud is that you usually have no idea who robbed you. What you have is a wallet address — a string of characters — and perhaps a username, an email, a Telegram handle. Singapore courts have accepted that this is enough to start proceedings. In CLM v CLN the defendants were sued as unknown persons, described by reference to what they had done and the addresses they controlled. The description must be precise enough that, once identified, a person either clearly falls within it or clearly does not.

Service — normally the delivery of court papers to a person at a place — adapts too. Where the defendant exists only online, Singapore courts have permitted substituted service by the very channels the defendant used: email, messaging platforms, social media accounts. The practical sequence in a typical case runs: injunction first, disclosure orders against exchanges next, then formal service on the now-identified (or still-anonymous) defendant, and — since fraudsters rarely instruct counsel and appear — judgment in default at the end. A default judgment against a wallet address may sound hollow, but it is the key that unlocks enforcement against whatever assets the disclosure exercise has found.

Making exchanges talk: disclosure orders

Between you and the thief usually stands an exchange — and exchanges, unlike wallets, know their customers. Licensed platforms collect identity documents, bank details and login records as part of their onboarding checks. The mechanism for extracting that information is a disclosure order against the exchange as an innocent third party mixed up in the wrongdoing — the Norwich Pharmacal jurisdiction, explained in our dedicated guide to Norwich Pharmacal orders. In CLM v CLN, orders were made against exchanges with a Singapore presence to disclose information about the accounts into which the stolen assets had flowed.

Three practical cautions. First, the order binds the exchange, not the coins: pair it with a request (and where possible an order) that the account be frozen, or the disclosure may arrive after the assets have gone. Second, disclosure is only as good as the exchange's onboarding checks — a determined fraudster may have opened the account with stolen or synthetic identity documents, and the trail ends at someone else's passport. Third, jurisdiction matters: a Singapore order is straightforwardly effective against exchanges with operations here, while purely offshore platforms may require proceedings in their home courts. Many of the major exchanges have Singapore entities or licences, which is precisely what makes Singapore a natural forum for this work.

NFTs get the same protection: the Bored Ape case

The property analysis is not confined to fungible tokens. In Janesh s/o Rajkumar v Unknown Person [2022] SGHC 264, the claimant had borrowed cryptocurrency against his Bored Ape Yacht Club NFT — a well-known digital collectible — from a lender he knew only by an online handle. When the relationship soured, the lender foreclosed and took control of the NFT. The High Court granted an injunction restraining any dealing with the NFT, accepting that an NFT is capable of being property that the courts will protect, that proceedings could run against a defendant known only by a username, and that court documents could be served through the defendant's online accounts.

The decision matters beyond its striking facts. It confirms that Singapore's crypto jurisprudence extends across the asset class — coins, stablecoins, NFTs — and it shows the court treating a purely online lending arrangement, conducted pseudonymously across borders, as ordinary commercial litigation with ordinary remedies. For anyone using digital assets as loan collateral, it is also a caution: the deal terms you agree in a Discord chat are still contract terms, and untangling them later is expensive.

When the platform is the counterparty: Quoine v B2C2

Not every crypto dispute involves a thief. Sometimes the fight is with the exchange itself — over a reversed trade, a frozen account, a platform malfunction. The leading authority is Quoine Pte Ltd v B2C2 Ltd [2020] SGCA(I) 2. A glitch on Quoine's platform led B2C2's trading algorithm to execute trades at roughly 250 times the prevailing market rate. Quoine unwound the trades; B2C2 sued. The Court of Appeal held that the reversal breached the platform's own terms, which stated that executed orders were irreversible, and Quoine was liable in contract.

Two aspects of the decision repay attention. On unilateral mistake, Quoine argued the trades were vitiated because the prices were absurd and B2C2 must have known it. The court held that where contracts are formed by deterministic algorithms, the relevant state of knowledge is that of the humans who programmed them, assessed when the code was written — and on the facts the mistake doctrine did not save Quoine. On trust, the majority rejected the claim that the exchange held customers' assets on trust: holding customer balances, even segregated ones, does not by itself show the certainty of intention a trust requires. That second holding matters enormously if a platform fails — whether you are a trust beneficiary or an unsecured creditor can determine whether you recover anything at all — and it turns, unglamorously, on the platform's terms of service. Read them before you deposit, not after.

The SICC: a venue built for cross-border crypto fights

Larger disputes often land in the Singapore International Commercial Court, a specialist division of the General Division of the High Court designed for international commercial cases. Its bench includes eminent international judges from other common law and civil law jurisdictions, its procedures are adapted for cross-border disputes, and in qualifying offshore cases parties may be represented by registered foreign counsel. The Quoine litigation itself was heard there at first instance. For a crypto dispute with parties in three countries, assets on servers in none of them, and contractual documents drafted under foreign law, the SICC is one of the most credible forums in Asia — and exchange terms of service increasingly nominate Singapore as the seat for exactly that reason.

First steps if you have been scammed

The law above is only as useful as the evidence and speed you bring to it. If your crypto has been stolen or scammed away, the first week matters more than the following year:

Preserve everything immediately. Transaction hashes, wallet addresses, screenshots of the scam website or chat with URLs and timestamps, emails, payment records. Fraudsters delete channels fast; your evidence should outlive them.
Report to the police. Lodge a report with the Singapore Police Force promptly. Police action can trigger account freezes through channels no civil litigant can access, and a police report is standard supporting evidence for later applications.
Notify the exchanges on the trail. Write to every exchange the coins touched, identify the transactions, and ask them to freeze the destination accounts pending court orders. Compliance teams at licensed exchanges do act on credible fraud notifications — but only while the assets are still there.
Get a tracing analysis. Blockchain analytics firms can map the flow of funds from your wallet to exchange deposit addresses. Courts expect this evidence; without it you cannot identify whom to enjoin or which exchange to ask.
Take advice on proportionality before you commit. Interim injunctions and disclosure applications front-load tens of thousands of dollars in costs. That is rational for a large loss and ruinous for a small one — be honest about the arithmetic at the start.

Do not sit on the claim while you deliberate. Most contract and tort claims in Singapore carry a six-year limitation period, but the practical deadline — the interval in which the coins remain traceable and freezable — is measured in days and weeks, not years.

Realistic prospects: winning is not recovering

A clear-eyed close. Singapore courts can recognise your property, freeze it worldwide, unmask account holders and enter judgment against defendants who never show their faces. What no court can do is conjure value out of a wallet that has been emptied through a mixer into an unregulated offshore platform. The cases that end well share a pattern: the victim moved within days, a meaningful tranche of the funds was still sitting on an exchange with a Singapore nexus, and the freeze landed before the withdrawal. The cases that end badly share the opposite pattern, and no amount of doctrine fixes them.

If the trail leads abroad, a Singapore judgment can be exported: our guide to enforcing foreign judgments explains the registration and common-law routes by which a judgment from one jurisdiction is collected in another. And where the loss is modest, the proportionate play may be the unglamorous one — police report, exchange notifications, and a written-off lesson — rather than proceedings whose costs would dwarf any recovery.

The law here is young, but its direction is unmistakable. In the span of a few years Singapore's courts have answered the questions that matter most to anyone holding digital assets: your coins are property, thieves hold them on trust for you, the courts will freeze them at speed, and anonymity is a weaker shield than the fraudsters believe. The rest — as ever in litigation — is evidence, speed and money.
