$290M was drained from Kelp DAO in April because a bridge trusted poisoned RPC data. Not a smart contract bug. Not a key leak. The RPCs lied — and the system believed them. Here's exactly how it happened, and how you prevent it: 🧵 https://t.co/KqUxAGnxLv

Chainlink ethereum:0x514910771af9ca656af840dff83e8264ecf986ca uses decentralized oracle networks that come to quorum for security to enable trillions RelayGuard uses Secure Mode to come to quorum with your RPC providers to stop you from losing millions Level up your RPC security with RelayGuard. https://t.co/6z8yN5enF1

🚨 “The RPC was up” just cost another project millions. One poisoned node. One bad read. One rug. Uptime ≠ correctness. RelayGuard changes the game: • Quorum checks across providers • Fail-closed (bad data = no data) • Signed verified responses + instant alerts Your dApp deserves better than blind trust.

🚨 The LayerZero/KelpDAO $290M+ RPC Poisoning Attack — And How RelayGuard Security Mode Would Have Stopped It Cold In April 2026, attackers (linked to Lazarus) didn’t hack keys, smart contracts, or the DVN itself. They went after the infrastructure layer: compromised a quorum of RPC nodes that LayerZero’s verifier relied on, swapped binaries to feed forged transaction data only to the DVN, and DDoS’d the clean nodes to force failover. Result? A fake cross-chain message got validated, draining ~$290-292M in rsETH. High uptime wasn’t enough. The poisoned nodes stayed responsive and returned correct data to monitoring tools — just not to the critical verifier. This is exactly why uptime alone is a dangerous priority for production RPCs. RelayGuard’s Security Mode changes the game: • Quorum verification down to the contract function — Your gateway fans out security-critical calls (e.g., eth_getTransactionReceipt, eth_getStorageAt, custom contract reads) to multiple independent providers in parallel. • Only returns results when they agree — If there’s disagreement (or no quorum), it fails closed. No silent bad data, no “it worked in testing.” • Method + contract-level policies — Require quorum on exactly the calls that matter. Import ABIs and set rules per function. • Signed receipts + divergence alerts — Every verified response comes with a tamper-evident receipt. Get instant Slack/email/webhook notifications the moment providers diverge. • Health-aware routing + failover on top — But security-first: correctness over raw uptime. https://t.co/yuPzCRSvzR In the LayerZero case, Security Mode would have detected the split responses from poisoned vs. clean nodes and refused to proceed with the fraudulent verification — forcing the attack to fail instead of succeeding via failover. For teams building bridges, oracles, lending protocols, or any high-value dApp: • Uptime gets you online. • Verified correctness keeps you solvent. Don’t let your RPC layer become the weakest link. Bring your existing providers (Alchemy, Infura, QuickNode, self-hosted, etc.), add RelayGuard as the trust layer, and sleep better knowing bad data gets rejected before it reaches your contracts. One stable, policy-driven endpoint. Quorum where it counts. Fail-closed by design. Check it out: https://t.co/yuPzCRSvzR

🚨 Stop trusting a single RPC response for anything critical. One node. One answer. One point of failure. That’s how millions get rugged, frontrun, or silently lied to every week. RelayGuard fixes it: ✅Quorum validation across multiple providers ✅Fail-closed by default (never return bad data) ✅Zero-trust reads for serious teams Free Beta Workshop (limited spots) https://t.co/6z8yN5enF1 #Web3 #Blockchain #Ethereum #DevTools #BuildInPublic
