WEEX Crypto News, 29 December 2025
In a recent incident, the Flow blockchain faced a significant security breach, marking a substantial setback for the network. This breach led to approximately $3.9 million worth of assets being illicitly transferred out of the network, precipitating a swift response from its validators who enacted a coordinated pause to forestall any further exploitation.
Understanding the Flow Blockchain’s Security Breach
The Flow Foundation, which is pivotal to the blockchain’s operation, confirmed this security lapse. The breach emphasizes the persistent vulnerability in digital networks, where unauthorized intrusions can result in substantial financial losses. Validators on the Flow network, acting promptly, executed a network suspension to mitigate further risks. This decisive action underscores the critical role of validators in safeguarding blockchain integrity.
Communication from the Flow Foundation affirms that user funds are secure, with no individual accounts being compromised during this breach. This reassurance highlights the resilience of the Flow network’s current security measures in protecting its users, despite the breach affecting a significant portion of assets at the network level.
Recovery and Response Plan
The Flow Foundation is currently working intensively with validators, core developers, and its ecosystem partners to devise an effective recovery plan. This collaborative effort aims to reestablish the network’s stability and confidence among its user base. As part of this recovery process, the technical steps necessary for restoring normal operations are under careful examination.
The network’s coordination phase is anticipated to conclude within the next two to three hours, demonstrating a commitment to transparency and timeliness. Users and stakeholders of the Flow blockchain can expect a detailed status update by late evening Pacific Time on December 29. This update aims to keep the community informed and reassured regarding the security and restoration tactics being employed.
Implications for the Flow Ecosystem
The implications of this incident for the Flow blockchain are multifaceted. Primarily, it serves as a stark reminder of the vulnerabilities inherent in even the most robust blockchain systems. It prompts a reevaluation of security protocols and paves the way for enhancing defensive measures against future breaches.
Additionally, this episode draws attention to the blockchain’s operational dynamics, particularly the interplay between technological infrastructure and community governance. The rapid response by validators to suspend network operations reflects the agility and responsiveness of decentralized governance structures in crisis scenarios.
FLOW Token Impact and Market Reaction
In the wake of the breach, the FLOW token experienced a noticeable market reaction. Over a 24-hour period, the token’s value dropped by 10.80%, bringing its market capitalization to around $171 million. This decline mirrors investor apprehension about the breach’s impact and their confidence in the network’s recovery process. However, the swift diplomatic and technical response may help stabilize market perceptions in the coming days.
A Final Word: Security in Decentralized Networks
As the cryptocurrency and blockchain space continually evolves, incidents like the Flow security breach reinforce the critical importance of comprehensive security measures. They highlight the effective role that coordinated community and validator responses play in mitigating risks and protecting assets. For those interested in participating in a secure and vigilant blockchain environment, Flow’s experience demonstrates the value of a proactive and resilient network strategy.

Disclaimer: Why Lighter is Severely Underestimated
Compared to other Perp Dexs, Lighter's valuation is a steal, not to mention when compared to multiples during the peak of a bull market.
Currently, most of the circulating chips are priced by early users of Hyperliquid. These people got rich by holding Perp Dex's tokens, and even for risk hedging, they would buy Lighter. 99% of VCs have missed out on $HYPE and are in urgent need of the next target.
Narrative occupies the majority of the token's valuation, and Lighter's signal is already very clear.
Today's token price is supported solely by "programmatic" spot buying (such as automatic buybacks). Unless the spot buying is strong enough, the token is unlikely to rise in value (refer to the lessons of ETHFI, GRASS). Currently, only the Perp Dex track has truly implemented this logic.
Lighter's Vlad has a close relationship with Robinhood's Vlad, and Robinhood is likely to direct orders to Lighter in the future.
The 0 fee rate business model is highly favored by users.
Whales all need privacy; no one wants their liquidation price to be watched by the whole network.
From the current OTC market perspective, Lighter's Fully Diluted Valuation (FDV) is around 3.3 billion USD. Assuming an airdrop ratio of 30%, its initial circulating market cap is approximately 750 million USD. For comparison, Hyperliquid's circulating market cap is as high as 8.2 billion USD.
Looking at revenue alone (Note: Lighter's revenue has not been market-validated for a year like Hyperliquid), by simply annualizing based on the revenue of the past month, Lighter's annualized revenue could reach 250 million USD. This means that Lighter's Price-to-Sales ratio (market cap/revenue) multiple is only 2.5 times, far lower than Hyperliquid's 7.6 times, ridiculously cheap.
Take a closer look at a closer competitor, Aster. Aster's TVL is comparable to Lighter's, with an Open Interest (OI) of about one billion more than Lighter's. However, its FDV reaches up to 7 billion, with a circulating market cap of around 2 billion. In contrast, Lighter's trading price is only one-third of Aster's.
Ask yourself: Even considering Aster's Binance/CZ halo, is Lighter's price at only one-third of Aster's reasonable? In my opinion, based on the current valuation, Lighter is severely undervalued fundamentally.
Looking at the fundamentals, you will find that only two tokens can sustain a high revenue multiple in the long run: Hyperliquid and DYDX. Why? The former has the most transparent buyback mechanism, while the latter has stood the test of time in this industry. Unlike other listed Perp Dexes, Lighter does not have a top-tier influencer like CZ or liquidity support from Coinbase to artificially pump, nor does it face the dilemma of "lack of real users" like other competitors.
Additionally, it is important to note that the over-the-counter market (SOTC) usually carries a discount because buyers bear default risks (if the opening price is twice as high as the OTC transaction price, sellers have an incentive to default), which causes people not to offer high prices in OTC but to wait and see the actual listing performance.
I choose to annualize based on the revenue of the last month for a reason: in the crypto world, everyone only has a 7-second memory, and no one has the ability to see clearly or trade for the future a year later. Therefore, only the immediate revenue of the last month is the most important indicator.
The reason why Hyperliquid was able to break out on an independent trend is that many early LPs did not believe in its model. This led to those sharp-sighted retail investors sweeping all the chips and then selling to the belated buyers at a high price.
In conversations with a large number of VCs over the past few months, I have noticed a phenomenon: except for Paradigm, almost everyone missed out on Hyperliquid. This means that every VC with a liquidity fund (the vast majority of them do) will try to catch the next $HYPE.
Who is the next Hyperliquid? It's quite simple; just do a "pattern matching" between Lighter's storyline and Hyperliquid, and you'll find it's Lighter.
Looking at the token distribution, you will find: the large holders of Hyperliquid have also become the large holders and deep users of Lighter. The secret to wealth for this group of people is simple: Hold
errorToken BuybackPassive spot buying is the only thing that can support the coin price. BTC has MicroStrategy's Saylor, ETH has Tom Lee, but for altcoins, the market only recognizes income buybacks. If you want to keep the price firm, you need passive buying in the form of buybacks. Hyperliquid understands this well.
Lighter is essentially a replica of Hyperliquid. Founder Vlad has made it clear that they will conduct buybacks. While you can't expect them to buy back 97% of the tokens, buying back 30% or 50% is reasonable. As long as there is an eight-figure (tens of millions) passive buy, this is attractive enough.
Note: In their $68 million financing (mainly for the insurance fund), the team has allocated some funds for token buybacks at TGE. This is similar to the early Hyperliquid's $75 million spot buy.
Vlad Tenev (Robinhood's Vlad1) previously interned at Addepar for Vlad (Vlad2) from Lighter, and that's how they met. Robinhood is an investor in Lighter, and Vlad1 is also an advisor to Lighter.
There have been numerous rumors in the industry about using Lighter on Robinhood's chain. Lighter's goal is composability and will be integrated into Ethereum L1, ultimately achieving collateralized LLP token lending. This composability aligns with Robinhood's vision of "tokenizing everything" and putting everything on-chain.
While this is speculation, I support the argument that Robinhood will acquire a significant stake in Lighter (whether through tokens or equity). Given the similarity of their Payment for Order Flow (PFOF) models, I speculate that once Robinhood holds Lighter shares, it will redirect a significant portion of its traffic to Lighter. This will further strengthen this narrative.
Although not limited to Lighter, RWA contract trading has proven to be a key early product-market fit. Data shows that Lighter's daily trading volume for all RWA products is $517 million, with an open interest (OI) of $271 million. Compared to Hyperliquid, Lighter is quickly catching up and even surpassing.
One key distinction is that Lighter's RWA service is not provided by a third party in the ecosystem, but rather self-operated. This makes coordination and onboarding of new assets smoother and faster. Additionally, Lighter's majority of trading volume comes from its FX contract, while Hyperliquid is mainly index contracts (80%). Ultimately, this will evolve into a pure competition of liquidity and order book depth to vie for users.
The derivative market is growing rapidly, and despite a loyal fan base on Twitter shouting "Hyperliquid is the only one," the market is large enough to accommodate multiple top players. Robinhood has also opened up futures trading, as futures have a strong foothold in the crypto space and are indeed a superior trading method compared to options.
Solving the full collateral issue is the most critical challenge that Hyperliquid has outsourced to Flood and Fullstack Trade. To my knowledge, Flood is at least 6 months away from solving this problem. Lighter's larger team is more likely to tackle this challenge. Yes, Hyperliquid has a first-mover advantage, but if Lighter can swiftly integrate this feature, they may well take a slice of their cake.
While Hyperliquid has built a cult-like community culture, its architecture has a fatal flaw for whales: complete transparency.
On Hyperliquid, leaderboards and on-chain data broadcast every large position, entry price, and liquidation point to the world. This turns trading into a PvP arena where predatory players like me can specifically hunt whales' liquidation orders and front-run large funds. Leveraging liquidation data to predict short-term tops and bottoms is traceable, and I know many traders continue to profit through this strategy.
Lighter positions itself as the antidote to this risk. By obfuscating trading flows and shielding position data, its operation is more akin to an on-chain dark pool rather than a standard DEX. For "smart money" and large funds, anonymity is not just a feature—it is a necessity. If you have a significant amount of funds, you absolutely cannot trade in a place that directly exposes your hand and liquidation point to the counterparty. As DeFi matures, venues that can protect user alpha will inevitably attract the largest flows of funds.
