In the past hour, total liquidations across the network reached $10.35 million, with $4.20 million from long positions, with $6.15 million from short positions. BTC liquidation $626,138.77, ETH liquidation $1.83 million.

According to official sources, the Gate Pre-IPOs project SpaceX (SPCX) has surpassed $300 million in subscriptions, and the subscription channel remains open. The product supports both USDT and GUSD for participation. Upon completion of the subscription, SPCX asset certificates will be 100% unlocked and enter the pre-market trading market. Furthermore, new subscribers can enjoy up to a 200% annualized return on their savings account; users choosing GUSD for subscription can enjoy a 2.9% minting bonus; VIP 5 and above users and super agents are receiving additional airdrop rewards, continuously enhancing the overall participation and return potential.

Odaily Planet Daily reports that Arbitrum announced on its X platform that its Security Committee has taken emergency measures to freeze approximately 30,766 ETH related to the KelpDAO attack. The committee acted based on attacker identification information provided by law enforcement agencies and used technical means to transfer the funds to an intermediate frozen wallet, completing the process without affecting other on-chain states or users. As of 11:26 PM ET on April 20th, the funds have been successfully transferred, the original address is no longer accessible, and further use of the funds will require Arbitrum's governance process and coordination with relevant parties.

According to PeckShield monitoring, Odaily Planet Daily reports that Kelp DAO attackers transferred 30,765 ETH (approximately $70.92 million) to a special address starting with 0x00000, suspected of destroying the coins.

Ripple has announced a phased roadmap to upgrade its XRP Ledger to quantum-resistant capabilities by 2028, according to Odaily. The plan includes developing a "Quantum-Day" contingency plan to address potential quantum computing threats and collaborating with Project Eleven for preliminary testing and validation. Ripple stated that this move aims to prepare for a post-quantum-secure transition, and the entire plan will proceed in four phases: Phase 1: Q-Day Contingency Preparedness (Already Launched). Establishing a Quantum Day (Q-Day) contingency response mechanism. If the existing classical encryption system is suddenly compromised, the network will immediately stop accepting traditional public-key signatures and forcibly migrate to quantum-secure accounts. Phase 2: Risk Assessment and Algorithm Testing (First Half of 2026). Comprehensively assessing the impact of post-quantum cryptography on the XRP Ledger network performance, storage, and bandwidth. Collaborating with Project Eleven to conduct validator-level testing and Devnet benchmarking, deploying the NIST-standardized ML-DSA quantum-secure signature scheme, and developing a post-quantum escrow wallet prototype. Phase 3: Devnet Hybrid Integration (Second Half of 2026). Integrate candidate post-quantum signature schemes in parallel with existing elliptic curve signatures on the developer network (Devnet), allowing developers to test performance and system impact without affecting the mainnet. Simultaneously explore post-quantum zero-knowledge proof primitives and homomorphic encryption for confidential transfers to advance the privacy and compliance capabilities of tokenized real-world assets on XRPL. Phase 4: Full Mainnet Upgrade (Target 2028). Submit a formal protocol amendment, which, after being approved by validators, will fully enable native post-quantum cryptography on the mainnet.
