Gate News message, on March 31, Google’s Quantum AI team released a white paper stating that future cryptography-related quantum computers (CRQC) will require fewer quantum resources than previously expected to break the elliptic-curve cryptography (ECC) currently widely used for encrypting cryptocurrencies. The white paper shows that the research team compiled two quantum circuits targeting the 256-bit elliptic-curve discrete logarithm problem (ECDLP-256): Scheme 1 uses fewer than 1,200 logical qubits and 90 million Toffoli gates, while Scheme 2 uses fewer than 1,450 logical qubits and 70 million Toffoli gates. Estimates indicate that the above circuits can complete the computation in a matter of minutes on superconducting quantum computers with fewer than 500,000 physical qubits, which is about 20 times fewer physical qubits than previously required. Google previously published a migration timeline for 2029, urging the cryptocurrency community to migrate the blockchain to post-quantum cryptography (PQC) before this deadline, and calling for avoiding exposure or reusing wallet addresses that may have vulnerabilities.

Ripple CTO: Kelp DAO Exploit Reflects Bridge Security Trade-Offs
David Schwartz, CTO Emeritus at Ripple, analyzed bridge security vulnerabilities following the $292 million Kelp DAO exploit. He noted that providers prioritized convenience over robust security, undermining essential protective features. The Kelp DAO breach stemmed from a private key leak, exacerbated by a simplified security configuration in their LayerZero implementation.

rsETH LayerZero bridge hacked, Aave and other protocols urgently freeze funds
Kelp DAO’s liquidity re-staking token rsETH was attacked on April 19 by a hacker exploiting a cross-chain message verification vulnerability, resulting in 116,500 rsETH being released to an address controlled by the attacker. Multiple DeFi protocols urgently froze related functions to address potential losses. LayerZero stated that it is actively fixing the vulnerability and will release a post-incident analysis report.

eth.limo domain hijacked; EasyDNS admits first social engineering attack in 28 years
The eth.limo domain was subject to DNS hijacking on April 17. The attacker, posing as a team member, successfully tricked the domain registrar EasyDNS into executing account recovery for the domain. Although this incident did not affect users, because the attacker did not obtain the DNSSEC key material, they were unable to bypass the trust chain. This incident highlighted the risks of social engineering in the crypto space and prompted eth.limo to switch to the Domainsure service, which does not support account recovery, to enhance security.

Curve Finance Suspends LayerZero Bridging as a Precaution, Limits CRV and crvUSD Bridge Access
Curve Finance has been attacked over LayerZero infrastructure related to rsETH, and has temporarily suspended cross-chain functionality to prevent risk, impacting CRV cross-chain bridging and the fast bridging of crvUSD. Founder Egorov said the incident demonstrates the risk of “non-isolated lending,” and proposed a fully isolated mode as an alternative. Kelp DAO also suffered losses of about $292 million due to the attack, affecting lending activity on the Aave platform.

A Kelp bridge hack spreads and affects Aave, as TVL plunges and bad debt surges to 196 million
Liquidity re-staking protocol Kelp’s cross-chain bridge was attacked, stealing 116,500 rsETH and depositing it into Aave V3, resulting in roughly $196 million in bad debt. Aave’s contracts were not affected, but the incident revealed the systemic risk of LRT collateral, prompting DeFi protocols to re-evaluate their risk models, which could lead to losses for stkAAVE holders.
