bridging

On August 10, UMX (The Unified Market Exchange), incubated by Avenir Group under Li Lin, announced the launch of an invitation-only public beta. UMX is positioned as a crypto-friendly securities platform for global professional investors, supporting spot, leverage, contract, and options trading of crypto assets, while also supporting real US stocks, ETFs, and US stock options trading. The aim is to connect crypto assets and real securities trading on the same platform, enhancing the capital efficiency of cross-asset trading.The public beta focuses on opening the capital link between crypto assets and securities accounts, supporting functions such as stablecoin exchange transfers, non-stablecoin collateralized lending, fiat account withdrawals and deposits, and the mutual conversion of securities holdings and stock tokens. To enhance cross-asset capital efficiency, the platform introduces a cross-asset margin mechanism, allowing financial assets to be used as margin. During the public beta, BTC and USDT financial products will also be launched, with the highest annualized returns reaching 2.5% and 5.5%, respectively. This public beta is invitation-only, and users who have not yet obtained a public beta code can reserve the official version and participate in the early bird benefits program.

According to Token Terminal data, in the past week, the amount of ETH bridged from the Ethereum mainnet (L1) to Robinhood Chain (L2) has increased by about 10 times, exceeding 100 million USD.It is reported that Robinhood Chain uses ETH as its native Gas token. Token Terminal indicates that if the adoption of this chain continues to grow, it may become a new important source of demand for ETH.

According to the official Lido blog, Lido DAO has revoked the "official" bridge endpoints for wstETH on nine networks: zkSync Era, Mode, Scroll, Mantle, Swell, Zircuit, Soneium, Polygon PoS, and Lisk, through a Snapshot vote.This move is a resource adjustment at the governance level and does not affect the technical operation of the related bridges and contracts. Users can still hold, transfer, or bridge back wstETH on the aforementioned networks to Ethereum. Lido will stop security monitoring, ecosystem, and market support for these networks, but no migration deadline will be set.

Syscoin released a bridge security incident report, disclosing details of the UTXO-to-NEVM bridging vulnerability incident. It is reported that this incident led to approximately 5 billion SYS being unauthorizedly released on the UTXO side. The related funds have since been returned to the official recovery address and destroyed through the standard OP_RETURN method, making them unusable by the protocol again, and the on-chain reported SYS supply has been restored to the expected value. The bridging function is currently still suspended, and the team is completing the final review and repair.

Syndicate has released an update regarding the recent security incident, stating that the leakage of private keys led to the malicious upgrade of bridging contracts on two chains, resulting in the theft of approximately 18.5 million SYND (about $330,000) and around $50,000 in customer tokens. Affected users will receive full compensation, and SYND holders will receive additional compensation.The attack involved multi-stage reconnaissance, infrastructure mapping, vulnerability exploitation development, and precise timing, ruling out the possibility of insider involvement. The root cause of the vulnerability was the storage of private keys in a password manager, and the upgrade process did not utilize multi-signature or hardware signing. Syndicate is strengthening security measures, including adding an encryption layer outside the password manager and implementing multi-signature or hardware signing for the upgrade path.

ChainCatcher reported live that Tang Bo, Assistant Dean of the Financial Research Institute at the Hong Kong University of Science and Technology, Fei Si, Partner at King & Wood Mallesons, Diao Zhi Hai, Head of International Wealth Management at China International Capital Corporation, and Gavin Wang, Managing Partner and Chief Investment Officer of SNZ Holding & SNZ Capital, jointly attended the HK Web3 Feastival roundtable discussion, sharing insights on "from asset registration" to "on-chain issuance," bridging the last mile of RWA cross-border compliance.Fei Si pointed out that the so-called "from asset registration to on-chain issuance" essentially establishes a replicable, sustainable, and legally compliant channel for "domestic assets, overseas issuance." He believes that the most critical aspect at this stage is to first establish a solid transaction structure and top-level product design, clarifying whether the product is classified as equity or debt, as this will directly determine the corresponding regulatory authorities, communication methods, and subsequent legal document arrangements.Diao Zhi Hai approached the issue from the practical perspective of traditional financial institutions, stating that the biggest challenge currently is not a single isolated pain point, but how to systematically connect multiple compliance nodes to form a truly implementable closed-loop mechanism. He indicated that RWA cross-border projects involve not only financial regulation but also data cross-border, cybersecurity, foreign exchange management, and other departmental collaborations. Therefore, it is essential to examine whether the underlying assets can be clearly defined and mapped on-chain, who qualifies as the issuer and controlling entity, and whether the non-financial regulatory requirements throughout the process have been incorporated into the plan.Gavin Wang entered the discussion from the investment and market demand perspective, emphasizing that the global trend of asset tokenization is certain, and that high-quality Chinese assets are still significantly undervalued overseas. This means that as long as the cross-border compliance path is opened, market demand genuinely exists. He believes that investment institutions are most concerned with whether the entire project has clear compliance boundaries and marketability: red lines cannot be crossed, and gray areas must be approached with caution. What is truly worth investing in are those asset types with clearer regulatory expectations that investors can more easily understand and accept. In the long term, he is optimistic about two types of Chinese cross-border RWA targets: one type is large, high-quality Chinese assets that are easily understood by overseas investors, and the other type includes high-end manufacturing, robotics, AI, and pharmaceutical pipelines that are still undervalued overseas but possess global competitiveness.

ether.fi posted on platform X that, guided by security partners, it will restore the LayerZero bridging functionality for weETH and eETH within the next 24 hours.ether.fi previously confirmed that its Liquid treasury was not directly exposed to the Kelp rsETH event risk, but decided to suspend the LayerZero cross-chain bridging functionality for weETH and eETH as a precautionary measure until the root cause of the Kelp rsETH event is clarified. Meanwhile, for Liquid (ETH, BTC, USD), sETHFI, and eBTC products, the relevant Teller contracts have been suspended to block the LayerZero OFT bridging path, and the deposit and withdrawal functions for the related assets have also been suspended. They are currently working closely with security partners.

Polymarket's latest data shows that the current probability of the market betting on "Will Kelp DAO share this loss?" is 25%.This market was established around the April 19 incident where the Kelp DAO bridge was attacked. The attacker exploited a LayerZero cross-chain messaging vulnerability, withdrawing approximately $292 million in rsETH from the bridge, causing damage to the collateral backing for rsETH holders on the L2 network.According to Polymarket's market rules, if Kelp DAO announces or implements a mechanism before April 30 to share part or all of the losses with mainnet rsETH holders (rather than having all losses borne by L2 holders), the market will be determined as "Yes"; otherwise, it will be "No".

The USDT0 cross-chain bridging infrastructure has resumed normal operations today, with system integrity and risk exposure unaffected. All in-transit transactions submitted before the suspension have been safely settled.Previously, USDT0 suspended OFT bridging services as a precautionary measure pending the investigation of the KelpDAO rsETH incident, emphasizing that USDT0 has no risk exposure related to this incident, and all USDT0 tokens remain fully backed 1:1 by USDT.

etherFi posted on platform X that its Liquid treasury is temporarily not directly exposed to the Kelp rsETH event risk, but as a precautionary measure, it has suspended the LayerZero cross-chain bridging functionality for weETH and eETH until the root cause of the Kelp rs ETH event is clarified.
