LayerZero Security Debate: $178M Still at Risk as Memecoin Opsec Scandal Breaks

 



A serious security debate has broken out around LayerZero Labs, one of the most widely used cross-chain messaging protocols in DeFi. What started as a question in the ETHSecurity Community Telegram has turned into a full public reckoning over how LayerZero handled both its multisig keys and its default library configurations.

The core issue is straightforward. LayerZero's default library contracts had no timelock and could be upgraded by LayerZero Labs to forge messages. Security researcher banteg confirmed that more than $3 billion in OFT value was sitting with that vulnerable default config when the Kelp rsETH exploit happened. Major protocols including Ethena and EtherFi were still using those risky defaults just weeks ago.

That alone would be a significant concern. But then came the onchain data. Researchers found that LayerZero multisig signers, the same keys securing user funds, were being used to trade memecoins, swap on DEXs, and bridge through third-party platforms like Hop. That activity connects production keys to random websites, which is a textbook phishing risk.

ChainLinkGod flagged on X that one signer wallet swapped ETH for a memecoin called McPepes on Uniswap. The LayerZero team said the activity was testing PEPE's OFT integration. Researchers disputed that explanation, noting PEPE had not been deployed when the trades happened.

Bryan from LayerZero Labs also acknowledged in the Telegram that the defaults are "made for teams who are not prioritizing security," which security researchers pointed out is an unusual thing to admit about a protocol handling billions in user value.

As of the latest data from banteg, $178 million in market-priced surface remains exposed through projects still using the vulnerable default config. LayerZero's Primo said the team is working through projects one by one to ensure configs are pinned directly.

The full breakdown of the security debate, the onchain receipts, and what this means for DeFi projects still running default configs is covered in detail over at CryptoNewsLive.org. If you are building on or holding funds in protocols using LayerZero's default configuration, this is worth reading carefully before the situation changes further.

Ripple Is Building XRPL's Defense Against Quantum Computing, and the Clock Is Already Running

Image
  Ripple has released a detailed plan to protect the XRP Ledger from quantum computing threats, and the timeline it has set is not aspirational. The target is full post-quantum cryptography readiness by 2028, with active work already underway in 2026. The roadmap runs four phases. The first is an emergency contingency for a scenario where quantum computers break classical cryptography ahead of schedule. Ripple calls this Q-Day readiness. In that scenario, the XRP Ledger would enforce a hard network shift, stopping classical public-key signatures and requiring users to migrate to quantum-safe accounts. The second and third phases cover 2026. Testing begins on NIST-recommended post-quantum algorithms under real XRPL workload conditions. Performance, storage, and bandwidth costs all get measured. Then hybrid deployment begins on Devnet, running quantum-resistant signatures alongside existing ones before anything touches the live network. Project Eleven, an organization working on cr...

Hoskinson Just Said Everything Nobody Else Will Say About Crypto in 2026

Image
  Charles Hoskinson spent over an hour on the O Show with host Wendo in April 2026 and covered ground that most crypto founders avoid in public interviews. The Midnight Network mainnet went live on March 31 with nine institutional node operators including Google Cloud, MoneyGram, Worldpay, Telegram, Vodafone's Pairpoint, eToro, Bullish, Blockdaemon, and Shielded Technologies. That alone is a headline. But it was not the most important thing he said. The AI agent argument is where this interview breaks from the usual. His position is that zero-knowledge proofs are not primarily a privacy feature. They are the only mechanism by which AI agents can verify each other's behavior. When an autonomous agent is managing your funds across multiple blockchains while you sleep, it needs mathematical proof infrastructure underneath it to constrain what it can do, protect your data without exposing it, and settle value in real time without a middleman. Midnight is being built for that future...

: KelpDAO's $292M Bridge Hack Just Broke Aave and Locked Real Lenders Out

Image
  On April 18, 2026, a single forged message on a cross-chain bridge became 2026's largest DeFi exploit. Someone called the lzReceive function on LayerZero's EndpointV2 contract, tricked KelpDAO's bridge into accepting it as a legitimate transfer, and walked away with 116,500 rsETH worth $292 million. That was 18% of rsETH's entire circulating supply, minted on Ethereum mainnet with nothing backing it. The attacker did not stop at the theft. The stolen rsETH went straight into Aave V3 as collateral, and against it, the attacker borrowed approximately $236 million in wrapped ETH. Real funds, borrowed against tokens that had just been fraudulently minted. Aave was left with roughly $280 million in bad debt, frozen rsETH markets on both V3 and V4, and an ETH utilization rate that hit 100%. That last number matters more than it sounds. When ETH utilization on Aave reaches 100%, lenders cannot withdraw. Real WETH suppliers, people who had deposited ETH into Aave's len...
