Summary
In Fantom Foundation Ltd v Multichain Foundation Ltd & Anor [2024] SGHC 173, the General Division of the High Court addressed the increasingly complex "valuation conundrum" inherent in assessing damages for the loss of cryptocurrency assets. The proceedings followed a default judgment obtained by the Claimant, Fantom Foundation Ltd, against two defendants involved in the operation of the "Multichain Bridge." The core of the dispute lay in a massive security breach on 7 July 2023, which saw over US$127 million in assets moved out of the bridge’s wallet, rendering the platform’s "wrapped" assets effectively worthless and breaching the contractual foundations of the cross-chain ecosystem.
The judgment is a significant contribution to Singapore’s burgeoning digital asset jurisprudence, particularly regarding the quantification of loss in volatile markets. Mohamed Faizal JC was tasked with determining the monetary equivalent of lost native FTM tokens and various stablecoins (USDT, USDC, DAI). The court’s analysis provides a robust framework for practitioners, emphasizing that while the "breach date rule" remains a starting point for compensatory damages, it is not an inflexible rule of law. The court signaled a willingness to depart from this rule where its application would result in injustice, particularly given the extreme price fluctuations characteristic of the cryptocurrency sector.
Ultimately, the court awarded the Claimant US$58,620.55 for its general damages claim and US$2,129,250 for its specific FTM claim. In doing so, the court relied heavily on expert evidence to navigate the technical nuances of "wrapped" tokens and the liquidity mechanisms of decentralized finance (DeFi). The decision underscores the necessity of high-quality evidentiary support under s 47(1) of the Evidence Act 1893 when inviting the court to ascribe value to digital assets that lack intrinsic value and rely solely on market perception.
Beyond the immediate financial awards, the case serves as a cautionary tale for operators of cross-chain bridges and a roadmap for claimants seeking to recover losses from protocol failures. It reinforces the principle that the compensatory objective—restoring the claimant to the position they would have occupied but for the breach—must override rigid adherence to historical valuation dates if those dates fail to reflect the economic reality of the loss.

What Were the Facts of This Case?
The Claimant, Fantom Foundation Ltd, is the developer and operator of the "Fantom Opera Chain," a smart contract platform. Its native cryptocurrency, FTM, is central to the network's governance and transaction fee structure. The Defendants, Multichain Foundation Ltd (the First Defendant) and Multichain Pte Ltd (the Second Defendant), operated the "Multichain Bridge." This bridge functioned as a critical piece of infrastructure in the decentralized finance (DeFi) ecosystem, allowing users to trade assets across different, otherwise illiquid blockchains.
The relationship between the parties was governed by two primary written agreements: the "Integration Agreement" and the "User Agreement." The Integration Agreement facilitated the connection of the Fantom blockchain to the Multichain platform. The User Agreement set out the terms and conditions for using the bridge. Under these arrangements, the bridge operated on a "lock-and-mint" mechanism. When a user deposited "source assets" (such as USDC or USDT) on one chain, the bridge would lock those assets and mint "wrapped assets" of equivalent value on the destination chain. These wrapped assets were essentially IOUs, representing a claim on the underlying collateral held by the bridge.
A crucial factual pillar of the Claimant's case was the representation that the bridge was decentralized and that the source assets were held on a 1:1 basis as a collateral custodian. The Claimant alleged that the User Agreement entitled any bearer of validly encrypted wrapped assets to "unwrap" them and collect the corresponding source assets. However, on 7 July 2023, a massive security breach occurred. Over US$127 million in assets were drained from the bridge's wallets. This breach was not merely a technical failure but a fundamental collapse of the trust and collateralization that underpinned the wrapped assets. Following the breach, the wrapped assets held by the Claimant became "de-pegged" and effectively lost their value, as the bridge could no longer fulfill redemption requests.
The Claimant's losses were categorized into two main heads. First, the "Damages Claim" related to source assets (USDT, USDC, and DAI) that the Claimant had deposited into the bridge. As of 6 July 2023, these assets had a market value of approximately US$61,829.70. Following the breach, the residual value of these wrapped assets was negligible, with the Claimant's expert, Mr. Gu Miao, noting they were worth only a fraction of their original value (e.g., the wrapped DAI was valued at approximately US$3,209.12). The Claimant sought the difference between the pre-breach value and the residual value.
The second head was the "FTM Claim." This arose from a "liquidity facility" arrangement where the Claimant provided 4.175 million FTM tokens to the First Defendant to facilitate bridge operations. The default judgment had already ordered the Defendants to return these tokens or, in the alternative, pay their value. Because the tokens were not returned, the court had to determine their monetary value. The Claimant’s legal counsel, Mr. Eliahu Bernstein, provided evidence regarding the nature of these transactions, while Mr. Gu Miao provided the technical valuation methodology. The Defendants did not participate in the assessment proceedings, leaving the court to evaluate the Claimant's uncontested (but still required to be proven) evidence.
What Were the Key Legal Issues?
The primary legal issue was the quantification of compensatory damages for the loss of cryptocurrency assets following a breach of contract. This required the court to address several sub-issues:
- The Valuation Conundrum: How should the court ascertain the market value of a highly volatile asset like cryptocurrency at a specific point in time? This involved determining which data sets and exchanges (e.g., Binance, Coinbase) provide a reliable "market price."
- The Temporal Element: Which point in time should be used for valuation? The court had to decide whether to strictly apply the "breach date rule" or adopt a different date (such as the date of the judgment or the date the loss was discovered) to satisfy the compensatory principle.
- The Nature of Wrapped Assets: How does the law treat the loss of "wrapped" tokens compared to "native" tokens? The court had to analyze whether the loss should be measured by the value of the underlying source assets or the (now diminished) value of the wrapped tokens themselves.
- Evidentiary Standards for Digital Assets: What level of expert evidence is required under s 47(1) of the Evidence Act 1893 to prove the value of cryptocurrency? The court needed to determine if the methodology used by the Claimant's expert was sufficiently robust.
- Mitigation of Loss: Whether the Claimant had a duty to mitigate its losses by selling the de-pegged wrapped assets immediately after the breach, and whether such mitigation was practically possible in a collapsing market.
How Did the Court Analyse the Issues?
The court began its analysis by reaffirming the fundamental principle of compensatory damages: the award should return the Claimant to the position it would have occupied had the breach not occurred. Citing [2022] 1 SLR 302 at [133], the court noted that while the "breach date rule" is a general principle, it is not an absolute rule of law. The court's primary duty is to achieve a fair assessment of loss.
The Breach Date Rule and its Exceptions
The court engaged deeply with the "breach date rule," which suggests that damages are typically assessed at the date of the breach. However, Mohamed Faizal JC highlighted that this rule can give rise to injustice in cases involving volatile assets. The court referenced the English position in Stanford International Bank Ltd (in liquidation) v HSBC Bank plc [2023] AC 761, where Lord Leggatt JSC stated:
"The error lies in the premise that loss caused by a breach of duty is generally to be assessed as at the date of the breach. There is no such rule of law." (at [46])
The court noted that in the context of cryptocurrency, the breach date rule might not always represent the best assessment methodology. If a claimant is unaware of the breach until later, or if there is no available market to mitigate the loss immediately, the rule must yield to the compensatory principle. The court also cited Hooper v Oats [2014] Ch 287 and the academic commentary of Andrew Dyson and Adam Kramer, "There is No ‘Breach Date Rule’" (2014) 130 LQR 259, to support the view that the valuation date is a matter of achieving justice rather than following a rigid formula.
Valuing Cryptocurrency: The Evidentiary Hurdle
The court applied [2023] SGHC 323 at [11], noting that the acceptance of any valuation ascribed to cryptocurrency must turn on the evidence presented. Because cryptocurrency has no "intrinsic value" and relies on "perceived value" (citing ByBit FinTech Limited v Ho Kai Xin & Others [2023] 5 SLR 1748 at [32]), the court required expert testimony under s 47(1) of the Evidence Act 1893.
The Claimant's expert, Mr. Gu Miao, utilized a methodology that involved taking the volume-weighted average price (VWAP) from major exchanges. The court found this approach persuasive as it smoothed out idiosyncratic price spikes on individual exchanges. For the "Damages Claim," the court accepted the valuation of the source assets as of 6 July 2023 (the day before the breach) as the baseline. It then subtracted the residual value of the wrapped assets post-breach. The court accepted that the Claimant could not have mitigated its losses further because the market for those specific wrapped assets had effectively collapsed, making them illiquid.
The FTM Claim and the Liquidity Facility
Regarding the 4.175 million FTM, the court had to value the tokens because the Defendants failed to return them as ordered in the default judgment. The court noted that the value of FTM had fluctuated significantly, even reaching a 2024 peak following the announcement of the default judgment. To avoid a windfall or an unfair penalty, the court looked for a valuation that reflected the market reality at the time the Claimant was deprived of the assets. The court ultimately accepted the Claimant's submission for a total of US$2,129,250 for this head, which represented the value of the FTM tokens based on the expert's market analysis.
The "Valuation Conundrum" in Practice
The court acknowledged the difficulty of pinpointing a single "market price" for an asset that trades 24/7 across global platforms. It noted that unlike traditional stocks, there is no "closing price" for cryptocurrency. However, by using the expert's data-driven approach, the court was able to arrive at a figure that was "neither speculative nor arbitrary." The court also referenced Kelvin Low and Eliza Mik’s "Pause the Blockchain Legal Revolution" (2020) 69(1) ICLQ 135, acknowledging the unique legal challenges posed by blockchain technology while maintaining that traditional legal principles of damages remain applicable and adaptable.
What Was the Outcome?
The court accepted the Claimant's submissions in their entirety regarding the quantum of loss. The operative orders were set out at paragraph [50] of the judgment:
"For the reasons I have given, I accepted the Claimant’s submissions and order as follows: (a) that the Defendants pay the Claimant damages in the sum of US$58,620.55; and (b) that the Defendants pay the Claimant damages in the sum of US$2,129,250, namely the equivalent value of the 4.175m FTM."
The total award amounted to US$2,187,870.55. The court specifically ordered the payments in US Dollars, reflecting the currency in which the losses were calculated and the international nature of the parties' dealings. The "Damages Claim" award of US$58,620.55 was derived from the original value of the deposited assets (US$61,829.70) minus the residual value of the wrapped assets post-breach. The court found that the Claimant was unable to mitigate these losses due to the lack of an available market for the compromised tokens.
The "FTM Claim" award of US$2,129,250 provided a final monetary resolution to the alternative order in the default judgment. Since the Defendants had not complied with the primary order to deliver the 4.175 million FTM tokens, the court's assessment provided the necessary "value" component to make the judgment enforceable as a debt. The court reserved the issue of costs for separate consideration, as indicated at paragraph [51].
Why Does This Case Matter?
This case is a landmark for practitioners dealing with digital asset litigation in Singapore for several reasons. First, it provides a clear judicial endorsement of using expert evidence to overcome the "valuation conundrum." By accepting the volume-weighted average price (VWAP) methodology, the court has signaled a pragmatic approach to the 24/7, multi-exchange reality of crypto markets. Practitioners can now point to this case as a precedent for how to structure valuation evidence in future claims.
Second, the judgment clarifies the application of the "breach date rule" in the context of high volatility. By citing Stanford International Bank and iVenture, the court has reinforced that the rule is a servant of the compensatory principle, not its master. This is particularly important for crypto-assets, where a delay of even a few days in discovering a breach can lead to massive price swings. The court's willingness to look at the date the Claimant was actually deprived of the asset's value, rather than a strictly technical breach date, provides a more equitable framework for recovery.
Third, the case highlights the legal risks associated with "wrapped" assets and cross-chain bridges. The court's analysis of the 1:1 collateralization requirement and the subsequent "de-pegging" provides a template for how to plead breaches in DeFi protocols. It recognizes that the value of a wrapped token is inextricably linked to the integrity of the bridge's custody of the source assets. When that custody is breached, the loss is not just the tokens themselves, but the collapse of the underlying contractual promise of 1:1 redemption.
Finally, the decision demonstrates the Singapore court's sophistication in handling technical blockchain concepts. From distinguishing between native and non-native coins to understanding the role of MPC (Multi-Party Computation) nodes, the judgment shows that the judiciary is well-equipped to apply traditional contract and damages law to "Web3" disputes. This enhances Singapore's reputation as a leading hub for digital asset dispute resolution.
Practice Pointers
- Expert Evidence is Mandatory: Do not rely on simple screenshots from CoinMarketCap. Use a qualified expert under s 47(1) of the Evidence Act to provide a robust valuation methodology, such as VWAP across multiple high-liquidity exchanges.
- Plead Alternative Values: When seeking the return of specific tokens, always plead an alternative monetary value. This ensures that if the tokens are not delivered, the court has a clear basis to award a specific USD or SGD sum.
- Address Mitigation Proactively: If a token "de-pegs" or a bridge is hacked, document the state of the market immediately. If the market becomes illiquid, use that evidence to explain why immediate mitigation (selling the assets) was impossible.
- Temporal Flexibility: Be prepared to argue for a valuation date other than the breach date if the latter would result in an unfair assessment of the actual economic loss.
- Currency of Award: Consider whether the award should be in USD or SGD. In this case, the court awarded damages in USD, which may be more appropriate for international crypto-transactions to avoid additional exchange rate volatility.
- Detail the Protocol Mechanism: When pleading a bridge failure, clearly outline the "lock-and-mint" or "collateral custodian" obligations. The court's understanding of the breach depends on a clear explanation of how the technology was supposed to work versus how it failed.
Subsequent Treatment
As a relatively recent 2024 decision, Fantom Foundation Ltd v Multichain Foundation Ltd has already begun to solidify the ratio that the assessment of cryptocurrency value must turn on the specific evidence presented to the court. It follows the trajectory set by [2023] SGHC 323, confirming that Singapore courts will treat digital assets as property capable of precise (if complex) valuation. Its treatment of the "breach date rule" is likely to be cited in any future Singapore case involving the assessment of damages for volatile assets, whether digital or traditional.
