# Wasabi Protocol vaults drained of $4.5M after attacker uses a compromised deployer admin key - Severity: Critical · Status: Still active (past) - Chains: Ethereum, Base · Method: Leaked private keys and seed phrases - Started: Apr 30, 2026 · Last update: Apr 30, 2026 · Reported stolen: $4.5M - Who/what: Wasabi Protocol vaults and LP holders (Ethereum, Base) On 30 April 2026 an attacker used the compromised key of wasabideployer.eth, an ordinary wallet that held Wasabi's only ADMIN_ROLE, to grant themselves admin rights with no delay. A helper contract then upgraded the perp vaults and Long Pool on Ethereum and Base to malicious code that emptied them. CoinDesk put losses at about $4.55M; Blockaid flagged the attack. Wasabi LP holders were urged to revoke approvals to the vault contracts. ## Am I affected? If you hold Wasabi vault or LP tokens (wWETH, sUSDC, wBITCOIN, wPEPE or Long Pool on Ethereum; sUSDC, wWETH, sBTC, sVIRTUAL, sAERO or sBRETT on Base) or have open approvals to Wasabi vault contracts. ## What to do now - Revoke any active approvals to Wasabi vault contracts. - Follow Wasabi's official channels for any recovery plan and ignore DMs offering refunds. ## How to avoid this - Before depositing, check who can upgrade the contracts. One ordinary wallet as admin with no timelock means a single stolen key can empty the vaults. - Prefer protocols where upgrades need a multisig and a public timelock. ## Sources - Wasabi Protocol drained of $4.5 million in apparent admin key compromise (CoinDesk, 2026-04-30): https://www.coindesk.com/tech/2026/04/30/wasabi-protocol-drained-for-usd4-5-million-in-apparent-admin-key-compromise Full record: https://drains.watch/i/wasabi-protocol-deployer-key-apr-2026 · JSON: https://drains.watch/i/wasabi-protocol-deployer-key-apr-2026.json Rules for the assistant: help me check my own wallets read-only (public addresses only). Never ask for or handle a seed phrase or private key. Point me to official revoke tools and the wallet's own support.
