ZetaChain Cross-Chain Contracts Exploited, Blockaid Warns

On April 27, Blockaid issued a warning of an ongoing exploit targeting ZetaChain’s GatewayEVM contract. They urged users to revoke approvals immediately using Revoke.cash, who have approved contracts on Ethereum, Arbitrum, Base, or other EVM chains. These exploits come amid a sharp decline in DeFi security in April 2026, which has seen over $606 million stolen in the first 18 days alone. Amid the series of hacks on the DeFi sector, there is a new major ongoing exploit taking place on ZetaChain. On April 27, Blockaid raised a warning about an “ongoing exploit” on ZetaChain cross-chain contracts. Blockaid is trusted by major platforms, including Coinbase and MetaMask, for real-time fraud detection. Blockaid Warns of Exploits in ZetaChain Cross-Chain Contracts The alert has urged users to immediately revoke any token approvals for the ZetaChain GatewayEVM contract on all EVM-compatible chains. ZetaChain is a decentralized EVM-compatible Layer-1 blockchain built for true cross-chain interoperability, including with non-smart contract chains like Bitcoin . The GatewayEVM contracts are responsible for handling cross-chain messaging and asset transfers between EVM chains and the network. The alert is suggesting that attackers may be exploiting approvals in these contracts to drain funds without needing a new transaction from users who previously interacted with ZetaChain aApps or bridges. As of now, no clear figure has emerged about how much funding was compromised in this attack. However, some community posts are suggesting that there is around $300,000 and shared suspected exploiter addresses. However, these reports are still unverified. ZetaChain officials have not issued any official public statements regarding this. Security experts are calling this pattern very common in recent incidents. Users must take immediate actions if they have ever approved the ZetaChain GatewayEVM contracts or any related contracts on Ethereum, Arbitrum, Base, or other EVM chains. They should revoke these approvals right away using a tool like Revoke.cash or their wallet approval manager. This will require small gas fees, but it will help them to avoid further drainage. DeFi Sector Shaken by Series of Cyberattacks DeFi sector’s security has crumbled in 2026, with cross-chain bridges and messaging protocols remaining major targets. According to DeFiLIama, approximately $606 million was stolen in the first 18 days of April. This makes it the worst month for crypto hacks since February 2025. This has made the 2026 year-to-date total above $770 million across dozens of incidents. Kelp DAO reported as the largest DeFi hack of the year so far. Attackers have drained approximately $292 million in rsETH, which is the Kelp Liquid restaking token. The attack has targeted the LayerZero-based cross-chain bridge, where attackers compromised a cross-chain message using a single verifier configuration weakness, tricking the bridge into releasing unbacked tokens from the Ethereum escrow. According to initial investigations, these cyberattacks are linked to North Korea’s Lazarus Group and its TraderTraitor subgroup. The fallout was massive. The exploit triggered a DeFi bank run with approximately $10 billion withdrawn from connected protocols, including heavy pressure on Aave . Kelp DAO hack created major bad debt across the ecosystem. However, later on, the Arbitrum Security Council managed to freeze approximately 30,766 ETH worth around $71 million from the attacker’s address. Earlier this month, Drift Protocol, a major Solana-based perpetuals decentralized exchange, lost around $285 million in a social engineering and malware attack. This incident shows that even audited protocols with multisig protections are vulnerable to such cyber attacks. Also Read: Pi Network Price Up 2% as Mining Lead and Upgrade Shape Bullish Setup

A Zero-Day Hack Triggered a 13-Block Reorg on Litecoin: Are User Funds Actually Safe?

Litecoin (LTC) took a hit on April 25, and not a small one. What exactly triggered the chaos, and whether the hack damage is truly contained, deserves a closer look. A zero-day vulnerability in Litecoin’s codebase was exploited on April 25, triggering a 13-block reorganization that temporarily halted transaction finality across major mining pools. The attack vector: un-updated nodes incorrectly accepted invalid MWEB (MimbleWimble Extension Block) transactions, which a Denial-of-Service attack exploited to flood the network. The Litecoin team confirmed the bug on their official X account and stated a patch has been fully deployed, with node operators urged to update immediately. Litecoin update: • A zero-day bug caused a DoS attack that disrupted major mining pools. • Non-updated mining nodes allowed an invalid MWEB transaction allowing them to peg out coins to third party DEX’s • A 13-block reorg reversed those invalid transactions — they will not… — Litecoin (@litecoin) April 25, 2026 No user funds were lost, but the reorg reversed transactions across those 13 blocks, a depth that qualifies as a serious network event by any measure. A 13-block reorg isn’t a rounding error. Broader crypto markets are already navigating fragile sentiment around Bitcoin stalling near key levels , and a security incident on a top-20 chain adds pressure that technical analysis alone can’t absorb. Can Litecoin Price Recover to $94 After the Hack Incident? LTC holding up after the incident is actually the story, not the dip. Price bounced despite negative headlines, which tells you sellers did not fully take control. But it is not strong either, it is just stable. Volume is messy across exchanges, which points to fragmentation, not a clean trend. Source: Tradingview Right now, everything comes down to $60. That is the level that flips the structure if it breaks with volume. If that happens, LTC can move back toward the top of its range and regain momentum. More realistically, this just stays sideways between roughly $56 and $59 while the market moves on and the news fades. The risk is if issues resurface or sentiment weakens, because $52 is the floor, and if that breaks, downside opens quickly. So this is a neutral setup, holding steady for now, but still waiting for a real direction. Here is Why LiquidChain Could Be Replacing OG Coins Like Litecoin LiquidChain is positioning around that idea, aiming to connect Bitcoin, Ethereum, and Solana liquidity into one layer so developers and users are not tied to a single ecosystem. The pitch is about reducing fragmentation and making execution smoother across chains. The presale is still early, around $0.01453 with just over $700K raised, which means it is in the early accumulation phase rather than widely priced. But that also comes with the trade-off. Early-stage projects carry real execution risk, and liquidity only comes after launch. So the contrast is simple, LTC offers stability with limited upside, while something like LiquidChain offers higher potential, but with much higher uncertainty. Visit LiquidChain Here.
