On April 29, the cross-chain sector presented a starkly contrasting industry landscape: on one hand, the shadow of security remains unlifted, as multiple data sources indicate that the Commons cross-chain bridge under Syndicate suffered a vulnerability attack, resulting in approximately 18.5 million SYND tokens being stolen and cashed out for about $330,000, with the funds transferred to Ethereum via cross-chain pathways. On the other hand, the iteration of underlying infrastructure is accelerating, as B.AI announced on the same day a collaboration with deBridge, aiming to provide financial support for the AI Agent economy through an intent-driven cross-chain architecture. According to reports on April 28, the daily active users (DAU) of cross-chain bridges have continuously declined to about 13,000, sharply contrasting with the intense technical actions on the supply side. At the same time, the Starknet Foundation revealed that strkBTC plans to launch on May 12, bringing privacy-preserving assets into the cross-chain landscape. These signals point to one fact: the cross-chain sector is undergoing a structural migration from "retail front-end tools" to "institution-level back-end facilities."

This section will deeply analyze the core signals of the cross-chain sector under the liquidity cooling cycle, focusing on recent intensive security events, the intent-driven technological evolution, and the market structure's shift from virtual to real. We will trace the origins of the security vulnerabilities at Syndicate, compare the intent execution logic of B.AI and deBridge, and discuss, in conjunction with Starknet's layout for privacy cross-chain assets, the underlying logic and industry trends of new players continuously entering to build an interoperability foundation in an environment rife with attack risks.

Commons Cross-Chain Bridge Hacked for $330,000

The shadow of security in the cross-chain sector remains. According to AiCoin data, on April 29, CertiK Alert disclosed that the Commons cross-chain bridge under Syndicate suffered a security breach. The attackers precisely exploited a protocol vulnerability to illegally obtain approximately 18.5 million SYND tokens, which they rapidly sold off in the market, making a profit of about $330,000. Monitoring shows that the relevant attack funds, after completing the exchange, have been transferred to the Ethereum network via the cross-chain bridge. This sell-off impacted the SYND token price, leading to significant community concerns over the underlying security of the protocol.

Syndicate officially confirmed the breach of the Commons cross-chain bridge on the same day and stated that it is investigating the unusual flow of SYND tokens. To prevent further losses, the official urgently advised users to stop providing liquidity to the protocol until the vulnerability is fully resolved. In response, the Syndicate team claimed to have collaborated with several security companies to fully track the on-chain traces of the attackers. Meanwhile, the official attempted to reassure the community, stating that it currently has enough token reserves to cover the losses of affected users and is researching specific compensation plans to mitigate the trust crisis caused by the security incident.

This attack event is not an isolated case, but in the sensitive period when the daily active users (DAU) of cross-chain bridges have declined to about 13,000, its negative impact is magnified. In the broader context of an overall cooling liquidity environment, the breach of the Commons cross-chain bridge has once again exposed the vulnerabilities of cross-chain channels concerning code logic and fund isolation. The frequent occurrence of security incidents not only directly causes on-chain asset losses but also undermines user trust in cross-chain infrastructure at a deeper level. This collapse of trust is forcing the market to reassess the forms of cross-chain products — when the traditional TVL pledging model faces ongoing security challenges, the industry urgently requires more robust technical solutions to reshape the security of cross-chain execution.

0-TVL and No Gas: deBridge Cross-Chain Reconstruction

On April 29, B.AI officially announced a strategic partnership with deBridge, as the two will jointly explore intent-centric cross-chain infrastructure. Positioned as a financial underlying facility for the AI Agent era, the core goal of this collaboration is to utilize deBridge's tech stack to provide a seamless and secure cross-chain execution environment for a scalable AI Agent economy. The 0-TVL model and no gas cross-chain technology offered by deBridge fundamentally reconstruct the asset transfer pathways — it no longer requires the establishment of a large liquidity pool on the target chain but achieves minimized collateralization of assets through efficient intent matching and settlement mechanisms, which perfectly aligns with the demands of high-frequency, low-friction execution in AI automated trading systems.

At the technological support level, deBridge's Multi-Chain Communication Protocol (MCP) and intent-driven Bundles have become key to advancing efficient autonomous trading systems. According to external social media information, deBridge's MCP landed on the TRON network on April 17, 2026, while its intent-driven Bundles went live in December 2025. These components allow AI Agents to complete cross-chain intent confirmations in complex on-chain environments in the form of bundled transactions, without requiring native gas tokens to be reserved on each chain. According to AiCoin data, this architecture not only enhances the interactive experience but also significantly reduces systemic exposure. Compared to the risks of funds being long-term locked in smart contracts in traditional cross-chain solutions, the decentralization and security properties emphasized by deBridge are becoming the core technological barrier for the new generation of cross-chain players entering the market.

This "light asset, heavy execution" model stands in stark contrast to the traditional cross-chain security incidents occurring on the same day. On April 29, according to CertiK and various media, Syndicate's Commons cross-chain bridge was attacked, with attackers exploiting a vulnerability to obtain approximately 18.5 million SYND tokens and quickly selling them for a profit of about $330,000; related funds have since been transferred to the Ethereum network via the cross-chain bridge. Syndicate officials subsequently confirmed the security incident and advised users to stop providing liquidity. In contrast to the painful lessons learned from the Commons attack, where reserve tokens were stolen due to vulnerabilities, the 0-TVL model promoted by B.AI and deBridge attempts to structurally avoid the risk of large-scale liquidity pools being locked by hackers by reducing the duration and exposure of assets during the bridging process. This shift from the "pool model" to the "intent execution model" is not only an iteration of cross-chain technology but also a defensive evolution in response to the continuously worsening security environment on-chain.

strkBTC Privacy Bridge to Launch: Betting on Security and Compliance

In the broader context of cross-chain security extending from protocol code to physical security, Starknet showcases another evolution path. Damian Chen, the Vice President of Growth at the Starknet Foundation, announced at the "Bitcoin 2026" conference that the zero-knowledge proof-based privacy Bitcoin wrapped asset strkBTC is scheduled to officially launch on May 12. The project maintains a 1:1 peg with Bitcoin and is initially cross-chain custodized via multi-signature governance by professional organizations such as UTXO, Twinsnake, Luganodes, and Xverse. Unlike traditional transparent bridging, the core competitive edge of strkBTC lies in its built-in privacy pool structure: after wrapping Bitcoin cross-chain to Starknet, all transactional and transfer paths within the pool are completely invisible to the outside, allowing external observers to only monitor the funds entering the bridge contract and the final outflow actions, thus severing the public association of funds' flows on-chain.

This extreme pursuit of privacy is not merely a technical showcase but based on severe data-driven on-chain security concerns. According to data cited by Damian Chen, incidents of personal attacks targeting crypto holders surged by approximately 75% in 2025 compared to the previous year, with France alone recording 41 relevant kidnapping cases this year. Meanwhile, the on-chain analytical environment is becoming increasingly transparent, with AI tools being able to associate on-chain addresses with real identities with about 90% accuracy in just seconds, and with very low operational costs. Against this backdrop, privacy cross-chain assets are seen as a necessary defensive line to protect users' personal safety. To achieve a balance between privacy and regulatory compliance, strkBTC introduces a "viewing key" mechanism, allowing users to hold this key to decrypt their transaction records and proactively present them when facing tax audits or law enforcement needs; at the same time, the protocol features a third-party asset screening mechanism to prevent sanctioned assets from entering the privacy pool.

From a technological evolution perspective, the strkBTC team is not stopping at the current multi-signature custodial model. According to project plans, although strkBTC is currently considered a trusted wrapped asset, there are future plans to upgrade to a trustless bridging solution based on BitVM. Once Starknet completes STARK verification, the protocol will further achieve native verification of Bitcoin. Furthermore, in response to potential threats to future computational capabilities, the team is researching quantum-resistant cryptographic solutions, attempting to establish long-term institutional-level trust through dual redundancy of security and compliance during the transformation of cross-chain bridges from "traffic entry" to "underlying infrastructure."

User DAUs Drop to 13,000: Cross-Chain Bridges Take a Backseat

As reported on April 28, the daily active users (DAU) in the cross-chain bridge industry have continuously declined to about 13,000. This data clearly reflects that retail users' enthusiasm for proactive cross-chain interactions is at a low ebb. The core logic driving large-scale user withdrawals lies in the collapse of security trust and the trend of cooling on-chain liquidity. On one side, recent frequent security events, such as the attack on Syndicate's Commons cross-chain bridge, have occurred; the attacker exploited vulnerabilities to obtain and sell approximately 18.5 million SYND tokens for a profit of about $330,000, greatly shaking users' foundational confidence in the security of cross-chain protocols. On the other side, as the marginal effects of airdrop rewards from major mainstream protocols decrease, user motivation to frequently cross-chain for excess profits has significantly diminished. According to AiCoin data, the shrinkage of the on-chain yield environment makes funds prefer to remain on their native chains or transfer through lower-cost pathways rather than incur high cross-chain costs to participate in interactions with unknown risks.

The market role of cross-chain bridges is undergoing a deep paradigm shift, transitioning from front-end products aimed at end-users to back-end infrastructure targeted at B-end and institutional users. This transformation is largely driven by deep diversions caused by chain abstraction technologies and centralized exchange platforms (CEX). For ordinary retail users, the deposit and withdrawal networks provided by centralized platforms already cover most cross-chain needs, while chain abstraction solutions obscure complex underlying logic at the application layer, allowing users not to be directly aware of the existence of cross-chain bridges. Although front-end DAU data appears sluggish, institutional-level trading and inter-protocol interoperability demands remain resilient behind the scenes. Cross-chain bridges are gradually evolving into financial underlying infrastructure, bearing invisible high-frequency asset settlement and instruction execution tasks in the AI Agent economy or automated execution systems. This transformation from "traffic entry" to "back-end plugins" signifies that cross-chain technology has entered a mature phase emphasizing stability and institutional compatibility.

From Bridge Being Hacked to Bridge Upgrades: What Signals to Watch in the Next Round of Cross-Chain Competition

The attack on the Commons cross-chain bridge, resulting in approximately 18.5 million SYND being sold off, alongside the intense debut of next-generation solutions like strkBTC and deBridge, collectively forms a vivid picture of contrasting fortunes in the current cross-chain market. This "old bridge losing blood, new bridge entering" growing pain is essentially the iteration of cross-chain architecture from a high-risk asset custodial model to a more resilient execution layer. According to AiCoin data, the DAU of cross-chain bridges has dropped to about 13,000, but this does not mean the exhaustion of interoperability demands; rather, the market narrative is shifting from a purely "traffic entry" perspective to a more privacy-, security-, and automation-friendly foundational form.

The core observation points for the subsequent market will focus on three dimensions: first is the rebuilding of security credibility; Syndicate's tracking of Commons attackers and the implementation of subsequent compensation plans will directly impact users' residual confidence in relay-type protocols; second is the real-world implementation of new cross-chain solutions, such as whether B.AI and deBridge's 0-TVL model can withstand the test of high-frequency execution in AI Agent's autonomous trading systems; and lastly, balancing compliance and privacy, as strkBTC plans to go live on May 12, its privacy pool and viewing key mechanism will be critical signals for the evolution of cross-chain infrastructure in addressing the growing personal safety risks (such as a 75% increase in personal attacks related to crypto in 2025) while meeting regulatory feedback through third-party screening mechanisms.
