Chaos Labs Locks Down After Suspected Nation-State Hack Attempt

The scare is pushing DeFi projects toward Chainlink for perceived reliability.

Overview

  • Chaos Labs detected suspicious activity in its operational wallets and moved into a full lockdown, rotating all operational keys.
  • The company said its oracle network was not breached and continues to run in an isolated environment separate from routine on-chain wallets.
  • Authorities and cybersecurity partners told Chaos Labs the tactics matched nation-state operations, a threat category that investigators say stole at least $578 million in April.
  • Projects are switching providers, with Tydro adopting Chainlink oracles, Kelp DAO shifting its rsETH feed to Chainlink, and Solv Protocol moving parts of its cross-chain setup from LayerZero to Chainlink.
  • The scare follows an April 2025 mispricing tied to a Chaos-linked oracle that triggered about $26.9 million in Aave liquidations, after which Aave and Chaos pledged reimbursements.
