ZRO giảm sập 22%: Làm thế nào để phản ánh rủi ro an ninh hạ tầng chuỗi chéo qua việc định giá chiết khấu hệ thống của token cầu?

Cross-chain Interoperability Protocol LayerZero’s native token ZRO experienced a sharp price adjustment in April 2026. As of April 22, 2026, Gate行情 data shows ZRO priced at $1.61, down 17.82% over the past 7 days, 18.86% over the past 30 days, and 35.61% over the past year. Meanwhile, its market cap has fallen back to $405 million, with a circulating market cap of about $1.6 billion, and the current circulation rate is only approximately 25.23%.

The immediate trigger for this decline was the KelpDAO rsETH cross-chain bridge attack. On the evening of April 18, attackers forged cross-chain messages, stealing 116,500 rsETH from KelpDAO’s bridging contract, worth about $294 million. ZRO dropped from around $2 before the incident to $1.4, with a maximum single-day decline of over 22%. Although the price recovered somewhat afterward, cracks in market confidence were clearly visible.

However, attributing ZRO’s decline solely to a security incident is insufficient to explain the deeper shifts in its pricing logic. The core issue lies in the market systematically applying a security discount to “bridge tokens,” a mechanism shaped by both emotional reactions to events and structural risk reassessment.

The Technical Roots of the $294 Million Cross-Chain Attack

At 17:35 UTC on April 18, 2026, a wallet that had been cleaned via Tornado Cash sent a cross-chain message to LayerZero’s EndpointV2 contract, claiming a user on a certain chain wanted to transfer rsETH back to the Ethereum mainnet. LayerZero’s decentralized validator network (DVN) verified this message, and KelpDAO’s bridge contract on the mainnet subsequently released 116,500 rsETH to an address controlled by the attacker.

The problem was that the “source chain” never actually received the rsETH deposit. The attacker poisoned the RPC infrastructure relied upon by the DVN, combined with DDoS attacks to force the system to switch to malicious nodes, successfully forging cross-chain transaction verification. Forty-six minutes later, KelpDAO’s emergency multisig pressed pause, while the attacker had already deposited the stolen rsETH into Aave V3 as collateral and borrowed approximately $236 million worth of wETH.

On a technical level, KelpDAO’s bridge contract used a 1/1 DVN configuration—relying on a single validator to confirm cross-chain messages. This setup shrinks the security boundary of the entire cross-chain verification process to a single point; if that infrastructure is compromised, the entire verification chain is exposed. In fact, Dune Analytics’ subsequent report shows that among 2,665 LayerZero-based OApp contracts, up to 47% use the same 1/1 DVN configuration, involving 1,252 projects. This indicates that the security vulnerability exposed by the KelpDAO incident is not isolated but a widespread risk across the ecosystem.

From Incident Shock to Systemic Discount

The price trend of ZRO clearly reflects how the market prices security events. After the incident, ZRO plunged from $2 to $1.4, a 18.15% drop within 24 hours, while AAVE fell 17.03%, LDO 13.11%, and KERNEL 11.26%. The entire Liquid Restaking Token sector and related DeFi protocol tokens suffered varying degrees of impact.

This downward transmission involves two layers. The first is liquidity shock: during ZRO’s rapid decline, a whale holding long positions on ZRO in Hyperliquid was partially liquidated, incurring a loss of about $2.88 million, with unrealized losses exceeding $750,000. The address “greenrooibos” on Polymarket also transferred about 97,800 ZRO (roughly $157,000) to exchanges shortly after withdrawal, with unrealized losses of about $47,000 compared to two weeks prior. Forced liquidation of leveraged positions and large holders’ stop-loss exits reinforced the downward price pressure.

The second layer is structural correlated pricing correction. As a liquidity staking token, rsETH is widely embedded in lending protocols like Aave, SparkLend, Fluid, and yield strategies, forming a deeply interconnected DeFi asset network. When the security of rsETH’s cross-chain bridge is discredited, other protocols relying on LayerZero infrastructure quickly take defensive measures—over 15 protocols have preemptively paused LayerZero OFT cross-chain bridging, including Ethena, TRON DAO, ApeChain, ether.fi, and Solv Protocol. Curve Finance also paused LayerZero-based CRV cross-chain bridges and crvUSD rapid bridges.

This “contagion of correlation” reveals a previously underpriced reality: when a foundational cross-chain protocol is embedded broadly in DeFi, its security incident’s impact does not stop at a single application but propagates through the asset network, ultimately manifesting as systemic discount in the native token’s price.

Redefining Bridge Tokens: From “Protocol Governance Rights” to “Infrastructure Insurance”

Before the KelpDAO incident, market valuation of ZRO mainly revolved around LayerZero’s cross-chain network effects and institutional narratives. LayerZero had integrated over 165 chains, with total cross-chain volume exceeding $225 billion, and over 159 million messages processed. Starting March 2026, Stargate’s 100% revenue flow was directed to ZRO buybacks, marking the first time protocol cash flows directly returned to token holders. The integration of Canton Network was also seen as a catalyst for unlocking the $8 trillion RWA market.

These narratives built a valuation framework centered on “network adoption + future cash flow.” However, the KelpDAO incident shattered this internal assumption. When LayerZero’s infrastructure proved vulnerable in a real attack, “network adoption” shifted from a positive factor to a risk amplifier—the more applications, the wider the potential impact of a single point of failure. The expected “future cash flow” was also eroded by reputational damage; multiple protocols’ preemptive pauses meant a short-term reduction in cross-chain traffic, affecting Stargate’s revenue and ZRO buyback scale.

The pricing logic of bridge tokens is undergoing a paradigm shift. Previously, the market tended to see cross-chain protocol tokens as “protocol governance + network usage” economic certificates, with value anchored to adoption scale and network effects. But repeated security incidents are forcing the market to redefine this asset class—bridge tokens’ value depends not only on protocol adoption but also on their resilience in security crises, their ability to absorb shocks, control contagion, and restore confidence.

In other words, the market is beginning to assign a previously overlooked pricing factor to bridge tokens: infrastructure risk premium. The size of this premium depends on the protocol’s security configuration flexibility, incident response speed, transparency of responsibility allocation, and ecosystem recovery capacity. The KelpDAO incident’s far greater price decline compared to other DeFi tokens reflects the market’s rapid pricing of this new risk factor.

Industry Perspective: Systemic Fragility of Cross-Chain Infrastructure

Looking beyond a single incident to the industry as a whole, the KelpDAO attack is not an isolated cross-chain bridge security failure. In recent years, cross-chain bridges have become one of the most frequent attack targets in crypto. The fundamental reason is that bridges are the essential gateways for value flow between different blockchains, inherently high-value aggregation points; at the same time, their security models involve multiple components—source chain, target chain, validator network, RPC nodes—any vulnerability can be exploited.

LayerZero’s modular security design—allowing applications to customize DVN configurations—was theoretically an architecture choice to enhance flexibility, but in practice has led to security differentiation. Data shows that 47% of OApp contracts based on LayerZero adopt the 1/1 DVN configuration, involving 1,252 projects. This indicates that most developers opt for “default” rather than “optimal” security configurations, partly due to higher operational costs and more complex deployment with multiple DVNs.

This “default insecure” ecosystem reflects a fundamental misalignment in the market’s expansion phase of cross-chain protocols—prioritizing integration of more chains and applications often comes at the expense of enforcing the highest security standards. The KelpDAO incident, costing $294 million, highlights the real market price of this strategic choice.

For the entire cross-chain interoperability sector, the long-term impact may include: accelerated standardization of security configurations, migration from single to multi-validator models, re-evaluation of insurance coverage for bridge tokens, and a systemic increase in user awareness of cross-chain asset risks.

Conclusion

The KelpDAO incident delivers more than a $294 million asset loss and a 22% single-day plunge in ZRO; it is a collective reflection on the pricing of cross-chain infrastructure risks. When bridge tokens’ value depends not only on how many chains they connect and how much transaction volume they handle but also on their resilience and responsibility in security crises, the entire valuation logic will undergo profound restructuring.

For LayerZero, the current challenge is not just fixing code but restoring trust. For the market, whether the systemic discount of bridge tokens is a short-term event-driven mispricing or a long-term structural shift in valuation will become clearer over the coming months, as security migration progresses, cross-chain traffic data accumulates, and ecosystem recovery unfolds.

As of April 22, 2026, Gate行情 data shows ZRO at $1.61, with a 24-hour trading volume of $1.04 million and a market cap of $405 million. The market is still waiting for the next move.
